-Vim has a number of internal variables and switches which can be set to
-achieve special effects.  These options come in three forms:
-	boolean		can only be on or off		*boolean* *toggle*
-	number		has a numeric value
-	string		has a string value
-
-==============================================================================
-1. Setting options					*set-option* *E764*
-
-							*:se* *:set*
-:se[t][!]		Show all options that differ from their default value.
-			When [!] is present every option is on a separate
-			line.
-
-:se[t][!] all		Show all but terminal options.
-			When [!] is present every option is on a separate
-			line.
-
-:se[t] termcap		Show all terminal options.  Note that in the GUI the
-			key codes are not shown, because they are generated
-			internally and can't be changed.  Changing the terminal
-			codes in the GUI is not useful either...
-			The options have the form t_AB, see
-			|terminal-options|.
-
-:se[t]! termcap		Idem, but don't use multiple columns.
-
-								*E518* *E519*
-:se[t] {option}?	Show value of {option}.
-
-:se[t] {option}		Toggle option: set, switch it on.
-			Number option: show value.
-			String option: show value.
-
-:se[t] no{option}	Toggle option: Reset, switch it off.
-
-							   *:set-!* *:set-inv*
-:se[t] {option}!   or
-:se[t] inv{option}	Toggle option: Invert value.
-
-				*:set-default* *:set-&* *:set-&vi* *:set-&vim*
-:se[t] {option}&	Reset option to its default value.  May depend on the
-			current value of 'compatible'.
-:se[t] {option}&vi	Reset option to its Vi default value.
-:se[t] {option}&vim	Reset option to its Vim default value.
-
-:se[t] all&		Set all options to their default value.  The values of
-			these options are not changed:
-			  all terminal options, starting with t_
-			  'columns'
-			  'cryptmethod'
-			  'encoding'
-			  'key'
-			  'lines'
-			  'term'
-			  'ttymouse'
-			  'ttytype'
-			Warning: This may have a lot of side effects.
-
-						*:set-args* *E487* *E521*
-:se[t] {option}={value}		or
-:se[t] {option}:{value}
-			Set string or number option to {value}.
-			For numeric options the value can be given in decimal,
-			hex (preceded with 0x) or octal (preceded with '0').
-			The old value can be inserted by typing 'wildchar' (by
-			default this is a <Tab> or CTRL-E if 'compatible' is
-			set).  See |cmdline-completion|.
-			White space between {option} and '=' is allowed and
-			will be ignored.  White space between '=' and {value}
-			is not allowed.
-			See |option-backslash| for using white space and
-			backslashes in {value}.
-
-:se[t] {option}+={value}				*:set+=*
-			Add the {value} to a number option, or append the
-			{value} to a string option.  When the option is a
-			comma-separated list, a comma is added, unless the
-			value was empty.
-			If the option is a list of flags, superfluous flags
-			are removed.  When adding a flag that was already
-			present the option value doesn't change.
-			Also see |:set-args| above.
-
-:se[t] {option}^={value}				*:set^=*
-			Multiply the {value} to a number option, or prepend
-			the {value} to a string option.  When the option is a
-			comma-separated list, a comma is added, unless the
-			value was empty.
-			Also see |:set-args| above.
-
-:se[t] {option}-={value}				*:set-=*
-			Subtract the {value} from a number option, or remove
-			the {value} from a string option, if it is there.
-			If the {value} is not found in a string option, there
-			is no error or warning.  When the option is a comma
-			separated list, a comma is deleted, unless the option
-			becomes empty.
-			When the option is a list of flags, {value} must be
-			exactly as they appear in the option.  Remove flags
-			one by one to avoid problems.
-			Also see |:set-args| above.
-
-The {option} arguments to ":set" may be repeated.  For example: >
-	:set ai nosi sw=3 ts=3
-If you make an error in one of the arguments, an error message will be given
-and the following arguments will be ignored.
-
-							*:set-verbose*
-When 'verbose' is non-zero, displaying an option value will also tell where it
-was last set.  Example: >
-	:verbose set shiftwidth cindent?
-<  shiftwidth=4 ~
-	  Last set from modeline line 1 ~
-  cindent ~
-	  Last set from /usr/local/share/vim/vim60/ftplugin/c.vim line 30 ~
-This is only done when specific option values are requested, not for ":verbose
-set all" or ":verbose set" without an argument.
-When the option was set by hand there is no "Last set" message.
-When the option was set while executing a function, user command or
-autocommand, the script in which it was defined is reported.
-Note that an option may also have been set as a side effect of setting
-'compatible'.
-A few special texts:
-	Last set from modeline line 1 ~
-		Option was set in a |modeline|.
-	Last set from --cmd argument ~
-		Option was set with command line argument |--cmd| or +.
-	Last set from -c argument ~
-		Option was set with command line argument |-c|, +, |-S| or
-		|-q|.
-	Last set from environment variable ~
-		Option was set from an environment variable, $VIMINIT,
-		$GVIMINIT or $EXINIT.
-	Last set from error handler ~
-		Option was cleared when evaluating it resulted in an error.
-
-{not available when compiled without the |+eval| feature}
-
-							*:set-termcap* *E522*
-For {option} the form "t_xx" may be used to set a terminal option.  This will
-override the value from the termcap.  You can then use it in a mapping.  If
-the "xx" part contains special characters, use the <t_xx> form: >
-	:set <t_#4>=^[Ot
-This can also be used to translate a special code for a normal key.  For
-example, if Alt-b produces <Esc>b, use this: >
-	:set <M-b>=^[b
-(the ^[ is a real <Esc> here, use CTRL-V <Esc> to enter it)
-The advantage over a mapping is that it works in all situations.
-
-You can define any key codes, e.g.: >
-	:set t_xy=^[foo;
-There is no warning for using a name that isn't recognized.  You can map these
-codes as you like: >
-	:map <t_xy> something
-<								*E846*
-When a key code is not set, it's like it does not exist.  Trying to get its
-value will result in an error: >
-	:set t_kb=
-	:set t_kb
-<	E846: Key code not set: t_kb ~
-
-The t_xx options cannot be set from a |modeline| or in the |sandbox|, for
-security reasons.
-
-The listing from ":set" looks different from Vi.  Long string options are put
-at the end of the list.  The number of options is quite large.  The output of
-"set all" probably does not fit on the screen, causing Vim to give the
-|more-prompt|.
-
-							*option-backslash*
-To include white space in a string option value it has to be preceded with a
-backslash.  To include a backslash you have to use two.  Effectively this
-means that the number of backslashes in an option value is halved (rounded
-down).
-A few examples: >
-   :set tags=tags\ /usr/tags	    results in "tags /usr/tags"
-   :set tags=tags\\,file	    results in "tags\,file"
-   :set tags=tags\\\ file	    results in "tags\ file"
-
-The "|" character separates a ":set" command from a following command.  To
-include the "|" in the option value, use "\|" instead.  This example sets the
-'titlestring' option to "hi|there": >
-   :set titlestring=hi\|there
-This sets the 'titlestring' option to "hi" and 'iconstring' to "there": >
-   :set titlestring=hi|set iconstring=there
-
-Similarly, in legacy script the double quote character starts a comment.  To
-include the '"' in the option value, use '\"' instead.  This example sets the
-'titlestring' option to 'hi "there"': >
-   :set titlestring=hi\ \"there\"
-
-In |Vim9| script it's simpler, comments start with a '#' character, and only
-when preceded by white space.  A backslash is needed less often: >
-   vim9script
-   set titlestring=hi\ "there"
-   set titlestring=hi#there#
-   set titlestring=hi\ \#there#
-
-For Win32 backslashes in file names are mostly not removed.  More precise: For
-options that expect a file name (those where environment variables are
-expanded) a backslash before a normal file name character is not removed.  But
-a backslash before a special character (space, backslash, comma, etc.) is used
-like explained above.
-There is one special situation, when the value starts with "\\": >
-   :set dir=\\machine\path	    results in "\\machine\path"
-   :set dir=\\\\machine\\path	    results in "\\machine\path"
-   :set dir=\\path\\file	    results in "\\path\file" (wrong!)
-For the first one the start is kept, but for the second one the backslashes
-are halved.  This makes sure it works both when you expect backslashes to be
-halved and when you expect the backslashes to be kept.  The third gives a
-result which is probably not what you want.  Avoid it.
-
-				*add-option-flags* *remove-option-flags*
-				*E539* *E550* *E551* *E552*
-Some options are a list of flags.  When you want to add a flag to such an
-option, without changing the existing ones, you can do it like this: >
-   :set guioptions+=a
-Remove a flag from an option like this: >
-   :set guioptions-=a
-This removes the 'a' flag from 'guioptions'.
-Note that you should add or remove one flag at a time.  If 'guioptions' has
-the value "ab", using "set guioptions-=ba" won't work, because the string "ba"
-doesn't appear.
-
-			   *:set_env* *expand-env* *expand-environment-var*
-Environment variables in specific string options will be expanded.  If the
-environment variable exists the '$' and the following environment variable
-name is replaced with its value.  If it does not exist the '$' and the name
-are not modified.  Any non-id character (not a letter, digit or '_') may
-follow the environment variable name.  That character and what follows is
-appended to the value of the environment variable.  Examples: >
-   :set term=$TERM.new
-   :set path=/usr/$INCLUDE,$HOME/include,.
-When adding or removing a string from an option with ":set opt-=val" or ":set
-opt+=val" the expansion is done before the adding or removing.
-
-
-Handling of local options			*local-options*
-
-Some of the options only apply to a window or buffer.  Each window or buffer
-has its own copy of this option, thus each can have its own value.  This
-allows you to set 'list' in one window but not in another.  And set
-'shiftwidth' to 3 in one buffer and 4 in another.
-
-The following explains what happens to these local options in specific
-situations.  You don't really need to know all of this, since Vim mostly uses
-the option values you would expect.  Unfortunately, doing what the user
-expects is a bit complicated...
-
-When splitting a window, the local options are copied to the new window.  Thus
-right after the split the contents of the two windows look the same.
-
-When editing a new buffer, its local option values must be initialized.  Since
-the local options of the current buffer might be specifically for that buffer,
-these are not used.  Instead, for each buffer-local option there also is a
-global value, which is used for new buffers.  With ":set" both the local and
-global value is changed.  With "setlocal" only the local value is changed,
-thus this value is not used when editing a new buffer.
-
-When editing a buffer that has been edited before, the options from the window
-that was last closed are used again.  If this buffer has been edited in this
-window, the values from back then are used.  Otherwise the values from the
-last closed window where the buffer was edited last are used.
-
-It's possible to set a local window option specifically for a type of buffer.
-When you edit another buffer in the same window, you don't want to keep
-using these local window options.  Therefore Vim keeps a global value of the
-local window options, which is used when editing another buffer.  Each window
-has its own copy of these values.  Thus these are local to the window, but
-global to all buffers in the window.  With this you can do: >
-	:e one
-	:set list
-	:e two
-Now the 'list' option will also be set in "two", since with the ":set list"
-command you have also set the global value. >
-	:set nolist
-	:e one
-	:setlocal list
-	:e two
-Now the 'list' option is not set, because ":set nolist" resets the global
-value, ":setlocal list" only changes the local value and ":e two" gets the
-global value.  Note that if you do this next: >
-	:e one
-You will get back the 'list' value as it was the last time you edited "one".
-The options local to a window are remembered for each buffer.  This also
-happens when the buffer is not loaded, but they are lost when the buffer is
-wiped out |:bwipe|.
-
-							*:setl* *:setlocal*
-:setl[ocal][!] ...	Like ":set" but set only the value local to the
-			current buffer or window.  Not all options have a
-			local value.  If the option does not have a local
-			value the global value is set.
-			With the "all" argument: display local values for all
-			local options.
-			Without argument: Display local values for all local
-			options which are different from the default.
-			When displaying a specific local option, show the
-			local value.  For a global/local boolean option, when
-			the global value is being used, "--" is displayed
-			before the option name.
-			For a global option the global value is
-			shown (but that might change in the future).
-
-:setl[ocal] {option}<	Set the local value of {option} to its global value by
-			copying the value.
-
-:se[t] {option}<	For |global-local| options: Remove the local value of
-			{option}, so that the global value will be used.
-
-							*:setg* *:setglobal*
-:setg[lobal][!] ...	Like ":set" but set only the global value for a local
-			option without changing the local value.
-			When displaying an option, the global value is shown.
-			With the "all" argument: display global values for all
-			local options.
-			Without argument: display global values for all local
-			options which are different from the default.
-
-For buffer-local and window-local options:
-	Command		 global value	    local value ~
-      :set option=value	     set		set
- :setlocal option=value	      -			set
-:setglobal option=value	     set		 -
-      :set option?	      -		       display
- :setlocal option?	      -		       display
-:setglobal option?	    display		 -
-
-
-Global options with a local value			*global-local*
-
-Options are global when you mostly use one value for all buffers and windows.
-For some global options it's useful to sometimes have a different local value.
-You can set the local value with ":setlocal".  That buffer or window will then
-use the local value, while other buffers and windows continue using the global
-value.
-
-For example, you have two windows, both on C source code.  They use the global
-'makeprg' option.  If you do this in one of the two windows: >
-	:set makeprg=gmake
-then the other window will switch to the same value.  There is no need to set
-the 'makeprg' option in the other C source window too.
-However, if you start editing a Perl file in a new window, you want to use
-another 'makeprg' for it, without changing the value used for the C source
-files.  You use this command: >
-	:setlocal makeprg=perlmake
-You can switch back to using the global value by making the local value empty: >
-	:setlocal makeprg=
-This only works for a string option.  For a number or boolean option you need
-to use the "<" flag, like this: >
-	:setlocal autoread<
-Note that for non-boolean and non-number options using "<" copies the global
-value to the local value, it doesn't switch back to using the global value
-(that matters when the global value changes later).  You can also use: >
-	:set path<
-This will make the local value of 'path' empty, so that the global value is
-used.  Thus it does the same as: >
-	:setlocal path=
-Note: In the future more global options can be made |global-local|.  Using
-":setlocal" on a global option might work differently then.
-
-
-						*option-value-function*
-Some options ('completefunc', 'imactivatefunc', 'imstatusfunc', 'omnifunc',
-'operatorfunc', 'quickfixtextfunc', 'tagfunc' and 'thesaurusfunc') are set to
-a function name or a function reference or a lambda function.  When using a
-lambda it will be converted to the name, e.g. "<lambda>123".  Examples:
->
-	set opfunc=MyOpFunc
-	set opfunc=function('MyOpFunc')
-	set opfunc=funcref('MyOpFunc')
-	set opfunc={a\ ->\ MyOpFunc(a)}
-
-Set to a script-local function: >
-	set opfunc=s:MyLocalFunc
-	set opfunc=<SID>MyLocalFunc
-In |Vim9| script the "s:" and "<SID>" can be omitted if the function exists in
-the script: >
-	set opfunc=MyLocalFunc
-
-Set using a funcref variable: >
-	let Fn = function('MyTagFunc')
-	let &tagfunc = Fn
-
-Set using a lambda expression: >
-	let &tagfunc = {t -> MyTagFunc(t)}
-
-Set using a variable with lambda expression: >
-	let L = {a, b, c -> MyTagFunc(a, b , c)}
-	let &tagfunc = L
-
-In Vim9 script, in a compiled function, you can use a lambda, but a
-closured does not work, because the function will be called without the
-context of where it was defined.
-
-
-Setting the filetype
-
-:setf[iletype] [FALLBACK] {filetype}			*:setf* *:setfiletype*
-			Set the 'filetype' option to {filetype}, but only if
-			not done yet in a sequence of (nested) autocommands.
-			This is short for: >
-				:if !did_filetype()
-				:  setlocal filetype={filetype}
-				:endif
-<			This command is used in a filetype.vim file to avoid
-			setting the 'filetype' option twice, causing different
-			settings and syntax files to be loaded.
-
-			When the optional FALLBACK argument is present, a
-			later :setfiletype command will override the
-			'filetype'.  This is to be used for filetype
-			detections that are just a guess.  |did_filetype()|
-			will return false after this command.
-
-				*option-window* *optwin*
-:bro[wse] se[t]			*:set-browse* *:browse-set* *:opt* *:options*
-:opt[ions]		Open a window for viewing and setting all options.
-			Options are grouped by function.
-			Offers short help for each option.  Hit <CR> on the
-			short help to open a help window with more help for
-			the option.
-			Modify the value of the option and hit <CR> on the
-			"set" line to set the new value.  For window and
-			buffer specific options, the last accessed window is
-			used to set the option value in, unless this is a help
-			window, in which case the window below help window is
-			used (skipping the option-window).
-			{not available when compiled without the |+eval|
-			feature}
-
-								*$HOME*
-Using "~" is like using "$HOME", but it is only recognized at the start of an
-option and after a space or comma.
-
-On Unix systems "~user" can be used too.  It is replaced by the home directory
-of user "user".  Example: >
-    :set path=~mool/include,/usr/include,.
-
-On Unix systems the form "${HOME}" can be used too.  The name between {} can
-contain non-id characters then.  Note that if you want to use this for the
-"gf" command, you need to add the '{' and '}' characters to 'isfname'.
-
-NOTE: expanding environment variables and "~/" is only done with the ":set"
-command, not when assigning a value to an option with ":let".
-
-							*$HOME-windows*
-On MS-Windows, if $HOME is not defined as an environment variable, then
-at runtime Vim will set it to the expansion of $HOMEDRIVE$HOMEPATH.
-If $HOMEDRIVE is not set then $USERPROFILE is used.
-
-This expanded value is not exported to the environment, this matters when
-running an external command: >
-	:echo system('set | findstr ^HOME=')
-and >
-	:echo luaeval('os.getenv("HOME")')
-should echo nothing (an empty string) despite exists('$HOME') being true.
-When setting $HOME to a non-empty string it will be exported to the
-subprocesses.
-
-
-Note the maximum length of an expanded option is limited.  How much depends on
-the system, mostly it is something like 256 or 1024 characters.
-
-							*:fix* *:fixdel*
-:fix[del]		Set the value of 't_kD':
-				't_kb' is     't_kD' becomes	~
-				  CTRL-?	CTRL-H
-				not CTRL-?	CTRL-?
-
-			(CTRL-? is 0o177 octal, 0x7f hex)
-
-			If your delete key terminal code is wrong, but the
-			code for backspace is alright, you can put this in
-			your .vimrc: >
-				:fixdel
-<			This works no matter what the actual code for
-			backspace is.
-
-			If the backspace key terminal code is wrong you can
-			use this: >
-				:if &term == "termname"
-				:  set t_kb=^V<BS>
-				:  fixdel
-				:endif
-<			Where "^V" is CTRL-V and "<BS>" is the backspace key
-			(don't type four characters!).  Replace "termname"
-			with your terminal name.
-
-			If your <Delete> key sends a strange key sequence (not
-			CTRL-? or CTRL-H) you cannot use ":fixdel".  Then use: >
-				:if &term == "termname"
-				:  set t_kD=^V<Delete>
-				:endif
-<			Where "^V" is CTRL-V and "<Delete>" is the delete key
-			(don't type eight characters!).  Replace "termname"
-			with your terminal name.
-
-							*Linux-backspace*
-			Note about Linux: By default the backspace key
-			produces CTRL-?, which is wrong.  You can fix it by
-			putting this line in your rc.local: >
-				echo "keycode 14 = BackSpace" | loadkeys
-<
-							*NetBSD-backspace*
-			Note about NetBSD: If your backspace doesn't produce
-			the right code, try this: >
-				xmodmap -e "keycode 22 = BackSpace"
-<			If this works, add this in your .Xmodmap file: >
-				keysym 22 = BackSpace
-<			You need to restart for this to take effect.
-
-==============================================================================
-2. Automatically setting options			*auto-setting*
-
-Besides changing options with the ":set" command, there are three alternatives
-to set options automatically for one or more files:
-
-1. When starting Vim initializations are read from various places.  See
-   |initialization|.  Most of them are performed for all editing sessions,
-   and some of them depend on the directory where Vim is started.
-   You can create an initialization file with |:mkvimrc|, |:mkview| and
-   |:mksession|.
-2. If you start editing a new file, the automatic commands are executed.
-   This can be used to set options for files matching a particular pattern and
-   many other things.  See |autocommand|.
-3. If you start editing a new file, and the 'modeline' option is on, a
-   number of lines at the beginning and end of the file are checked for
-   modelines.  This is explained here.
-
-					*modeline* *vim:* *vi:* *ex:* *E520*
-There are two forms of modelines.  The first form:
-	[text{white}]{vi:|vim:|ex:}[white]{options}
-
-[text{white}]		empty or any text followed by at least one blank
-			character (<Space> or <Tab>); "ex:" always requires at
-			least one blank character
-{vi:|vim:|ex:}		the string "vi:", "vim:" or "ex:"
-[white]			optional white space
-{options}		a list of option settings, separated with white space
-			or ':', where each part between ':' is the argument
-			for a ":set" command (can be empty)
-
-Examples:
-   vi:noai:sw=3 ts=6 ~
-   vim: tw=77 ~
-
-The second form (this is compatible with some versions of Vi):
-
-	[text{white}]{vi:|vim:|Vim:|ex:}[white]se[t] {options}:[text]
-
-[text{white}]		empty or any text followed by at least one blank
-			character (<Space> or <Tab>); "ex:" always requires at
-			least one blank character
-{vi:|vim:|Vim:|ex:}	the string "vi:", "vim:", "Vim:" or "ex:"
-[white]			optional white space
-se[t]			the string "set " or "se " (note the space); When
-			"Vim" is used it must be "set".
-{options}		a list of options, separated with white space, which
-			is the argument for a ":set" command
-:			a colon
-[text]			any text or empty
-
-Examples:
-   /* vim: set ai tw=75: */ ~
-   /* Vim: set ai tw=75: */ ~
-
-The white space before {vi:|vim:|Vim:|ex:} is required.  This minimizes the
-chance that a normal word like "lex:" is caught.  There is one exception:
-"vi:" and "vim:" can also be at the start of the line (for compatibility with
-version 3.0).  Using "ex:" at the start of the line will be ignored (this
-could be short for "example:").
-
-If the modeline is disabled within a modeline, subsequent modelines will be
-ignored.  This is to allow turning off modeline on a per-file basis.  This is
-useful when a line looks like a modeline but isn't.  For example, it would be
-good to start a YAML file containing strings like "vim:" with
-    # vim: nomodeline ~
-so as to avoid modeline misdetection.  Following options on the same line
-after modeline deactivation, if any, are still evaluated (but you would
-normally not have any).
-
-							*modeline-local*
-The options are set like with ":setlocal": The new value only applies to the
-buffer and window that contain the file.  Although it's possible to set global
-options from a modeline, this is unusual.  If you have two windows open and
-the files in it set the same global option to a different value, the result
-depends on which one was opened last.
-
-When editing a file that was already loaded, only the window-local options
-from the modeline are used.  Thus if you manually changed a buffer-local
-option after opening the file, it won't be changed if you edit the same buffer
-in another window.  But window-local options will be set.
-
-							*modeline-version*
-If the modeline is only to be used for some versions of Vim, the version
-number can be specified where "vim:" or "Vim:" is used:
-	vim{vers}:	version {vers} or later
-	vim<{vers}:	version before {vers}
-	vim={vers}:	version {vers}
-	vim>{vers}:	version after {vers}
-{vers} is 700 for Vim 7.0 (hundred times the major version plus minor).
-For example, to use a modeline only for Vim 7.0:
-	/* vim700: set foldmethod=marker */ ~
-To use a modeline for Vim after version 7.2:
-	/* vim>702: set cole=2: */ ~
-There can be no blanks between "vim" and the ":".
-
-
-The number of lines that are checked can be set with the 'modelines' option.
-If 'modeline' is off or 'modelines' is 0 no lines are checked.
-
-Note that for the first form all of the rest of the line is used, thus a line
-like:
-   /* vi:ts=4: */ ~
-will give an error message for the trailing "*/".  This line is OK:
-   /* vi:set ts=4: */ ~
-
-If an error is detected the rest of the line is skipped.
-
-If you want to include a ':' in a set command precede it with a '\'.  The
-backslash in front of the ':' will be removed.  Example:
-   /* vi:set fillchars=stl\:^,vert\:\|: */ ~
-This sets the 'fillchars' option to "stl:^,vert:\|".  Only a single backslash
-before the ':' is removed.  Thus to include "\:" you have to specify "\\:".
-							*E992*
-No other commands than "set" are supported, for security reasons (somebody
-might create a Trojan horse text file with modelines).  And not all options
-can be set.  For some options a flag is set, so that when the value is used
-the |sandbox| is effective.  Some options can only be set from the modeline
-when 'modelineexpr' is set (the default is off).
-
-Still, there is always a small risk that a modeline causes trouble.  E.g.,
-when some joker sets 'textwidth' to 5 all your lines are wrapped unexpectedly.
-So disable modelines before editing untrusted text.  The mail ftplugin does
-this, for example.
-
-Hint: If you would like to do something else than setting an option, you could
-define an autocommand that checks the file for a specific string.  For
-example: >
-	au BufReadPost * if getline(1) =~ "VAR" | call SetVar() | endif
-And define a function SetVar() that does something with the line containing
-"VAR".

-==============================================================================
-3. Options summary					*option-summary*
-
-In the list below all the options are mentioned with their full name and with
-an abbreviation if there is one.  Both forms may be used.
-
-In this document when a boolean option is "set" that means that ":set option"
-is entered.  When an option is "reset", ":set nooption" is used.
-
-For some options there are two default values: The "Vim default", which is
-used when 'compatible' is not set, and the "Vi default", which is used when
-'compatible' is set.
-
-Most options are the same in all windows and buffers.  There are a few that
-are specific to how the text is presented in a window.  These can be set to a
-different value in each window.  For example the 'list' option can be set in
-one window and reset in another for the same text, giving both types of view
-at the same time.  There are a few options that are specific to a certain
-file.  These can have a different value for each file or buffer.  For example
-the 'textwidth' option can be 78 for a normal text file and 0 for a C
-program.
-
-	global			one option for all buffers and windows
-	local to window		each window has its own copy of this option
-	local to buffer		each buffer has its own copy of this option
-
-When creating a new window the option values from the currently active window
-are used as a default value for the window-specific options.  For the
-buffer-specific options this depends on the 's' and 'S' flags in the
-'cpoptions' option.  If 's' is included (which is the default) the values for
-buffer options are copied from the currently active buffer when a buffer is
-first entered.  If 'S' is present the options are copied each time the buffer
-is entered, this is almost like having global options.  If 's' and 'S' are not
-present, the options are copied from the currently active buffer when the
-buffer is created.
-
-Hidden options						*hidden-options*
-
-Not all options are supported in all versions.  This depends on the supported
-features and sometimes on the system.  A remark about this is in curly braces
-below.  When an option is not supported it may still be set without getting an
-error, this is called a hidden option.  You can't get the value of a hidden
-option though, it is not stored.
-
-To test if option "foo" can be used with ":set" use something like this: >
-	if exists('&foo')
-This also returns true for a hidden option.  To test if option "foo" is really
-supported use something like this: >
-	if exists('+foo')

-A jump table for the options with a short description can be found at |Q_op|.
-
-					*'aleph'* *'al'* *aleph* *Aleph*
-'aleph' 'al'		number	(default 128 for MS-Windows, 224 otherwise)
-			global
-			{only available when compiled with the |+rightleft|
-			feature}
-	The ASCII code for the first letter of the Hebrew alphabet.  The
-	routine that maps the keyboard in Hebrew mode, both in Insert mode
-	(when hkmap is set) and on the command-line (when hitting CTRL-_)
-	outputs the Hebrew characters in the range [aleph..aleph+26].
-	aleph=128 applies to PC code, and aleph=224 applies to ISO 8859-8.
-	See |rileft.txt|.
-
-			*'allowrevins'* *'ari'* *'noallowrevins'* *'noari'*
-'allowrevins' 'ari'	boolean	(default off)
-			global
-			{only available when compiled with the |+rightleft|
-			feature}
-	Allow CTRL-_ in Insert and Command-line mode.  This is default off, to
-	avoid that users that accidentally type CTRL-_ instead of SHIFT-_ get
-	into reverse Insert mode, and don't know how to get out.  See
-	'revins'.
-	NOTE: This option is reset when 'compatible' is set.
-
-			 *'altkeymap'* *'akm'* *'noaltkeymap'* *'noakm'*
-'altkeymap' 'akm'	boolean (default off)
-			global
-			{only available when compiled with the |+farsi|
-			feature}
-	This option was for using Farsi, which has been removed.  See
-	|farsi.txt|.
-
-						*'ambiwidth'* *'ambw'*
-'ambiwidth' 'ambw'	string (default: "single")
-			global
-	Only effective when 'encoding' is "utf-8" or another Unicode encoding.
-	Tells Vim what to do with characters with East Asian Width Class
-	Ambiguous (such as Euro, Registered Sign, Copyright Sign, Greek
-	letters, Cyrillic letters).
-
-	There are currently two possible values:
-	"single":	Use the same width as characters in US-ASCII.  This is
-			expected by most users.
-	"double":	Use twice the width of ASCII characters.
-							*E834* *E835*
-	The value "double" cannot be used if 'listchars' or 'fillchars'
-	contains a character that would be double width.  These errors may
-	also be given when calling setcellwidths().
-
-	The values are overruled for characters specified with
-	|setcellwidths()|.
-
-	There are a number of CJK fonts for which the width of glyphs for
-	those characters are solely based on how many octets they take in
-	legacy/traditional CJK encodings.  In those encodings, Euro,
-	Registered sign, Greek/Cyrillic letters are represented by two octets,
-	therefore those fonts have "wide" glyphs for them.  This is also
-	true of some line drawing characters used to make tables in text
-	file.  Therefore, when a CJK font is used for GUI Vim or
-	Vim is running inside a terminal (emulators) that uses a CJK font
-	(or Vim is run inside an xterm invoked with "-cjkwidth" option.),
-	this option should be set to "double" to match the width perceived
-	by Vim with the width of glyphs in the font.  Perhaps it also has
-	to be set to "double" under CJK MS-Windows when the system locale is
-	set to one of CJK locales.  See Unicode Standard Annex #11
-	(http://www.unicode.org/reports/tr11).
-
-	Vim may set this option automatically at startup time when Vim is
-	compiled with the |+termresponse| feature and if |t_u7| is set to the
-	escape sequence to request cursor position report.  The response can
-	be found in |v:termu7resp|.
-
-			*'antialias'* *'anti'* *'noantialias'* *'noanti'*
-'antialias' 'anti'	boolean (default: off)
-			global
-			{only available when compiled with GUI enabled
-			on macOS}
-	This option only has an effect in the GUI version of Vim on macOS
-	v10.2 or later.  When on, Vim will use smooth ("antialiased") fonts,
-	which can be easier to read at certain sizes on certain displays.
-	Setting this option can sometimes cause problems if 'guifont' is set
-	to its default (empty string).
-	NOTE: This option is reset when 'compatible' is set.
-
-			*'autochdir'* *'acd'* *'noautochdir'* *'noacd'*
-'autochdir' 'acd'	boolean (default off)
-			global
-			{only available when compiled with it, use
-			exists("+autochdir") to check}
-	When on, Vim will change the current working directory whenever you
-	open a file, switch buffers, delete a buffer or open/close a window.
-	It will change to the directory containing the file which was opened
-	or selected.  When a buffer has no name it also has no directory, thus
-	the current directory won't change when navigating to it.
-	Note: When this option is on some plugins may not work.
-
-			*'autoshelldir'* *'asd'* *'noautoshelldir'* *'noasd'*
-'autoshelldir' 'asd'	boolean (default off)
-			global
-	When on, Vim will change the current working directory whenever you
-	change the directory of the shell running in a terminal window. You
-	need proper setting-up, so whenever the shell's pwd changes an OSC 7
-	escape sequence will be emitted.  For example, on Linux, you can
-	source /etc/profile.d/vte.sh in your shell profile if you use bash or
-	zsh.  For bash this should work (put it in a bash init file): >
-		if [[ -n "$VIM_TERMINAL" ]]; then
-		    PROMPT_COMMAND='_vim_sync_PWD'
-		    function _vim_sync_PWD() {
-			printf '\033]7;file://%s\033\\' "$PWD"
-		    }
-		fi
-<
-	Or, in a zsh init file: >
-		if [[ -n "$VIM_TERMINAL" ]]; then
-		    autoload -Uz add-zsh-hook
-		    add-zsh-hook -Uz chpwd _vim_sync_PWD
-		    function _vim_sync_PWD() {
-			printf '\033]7;file://%s\033\\' "$PWD"
-		    }
-		fi
-<
-	In a fish init file: >
-		if test -n "$VIM_TERMINAL"
-		    function _vim_sync_PWD --on-variable=PWD
-			printf '\033]7;file://%s\033\\' "$PWD"
-		    end
-		end
-<
-	You can find an alternative method at |terminal-autoshelldir|.
-	When the parsing of the OSC sequence fails you get *E1179* .
-
-				*'arabic'* *'arab'* *'noarabic'* *'noarab'*
-'arabic' 'arab'		boolean (default off)
-			local to window
-			{only available when compiled with the |+arabic|
-			feature}
-	This option can be set to start editing Arabic text.
-	Setting this option will:
-	- Set the 'rightleft' option, unless 'termbidi' is set.
-	- Set the 'arabicshape' option, unless 'termbidi' is set.
-	- Set the 'keymap' option to "arabic"; in Insert mode CTRL-^ toggles
-	  between typing English and Arabic key mapping.
-	- Set the 'delcombine' option
-	Note that 'encoding' must be "utf-8" for working with Arabic text.
-
-	Resetting this option will:
-	- Reset the 'rightleft' option.
-	- Disable the use of 'keymap' (without changing its value).
-	Note that 'arabicshape' and 'delcombine' are not reset (it is a global
-	option).
-	NOTE: This option is reset when 'compatible' is set.
-	Also see |arabic.txt|.
-
-					*'arabicshape'* *'arshape'*
-					*'noarabicshape'* *'noarshape'*
-'arabicshape' 'arshape'	boolean (default on)
-			global
-			{only available when compiled with the |+arabic|
-			feature}
-	When on and 'termbidi' is off, the required visual character
-	corrections that need to take place for displaying the Arabic language
-	take effect.  Shaping, in essence, gets enabled; the term is a broad
-	one which encompasses:
-	  a) the changing/morphing of characters based on their location
-	     within a word (initial, medial, final and stand-alone).
-	  b) the enabling of the ability to compose characters
-	  c) the enabling of the required combining of some characters
-	When disabled the display shows each character's true stand-alone
-	form.
-	Arabic is a complex language which requires other settings, for
-	further details see |arabic.txt|.
-	NOTE: This option is set when 'compatible' is set.
-
-			*'autoindent'* *'ai'* *'noautoindent'* *'noai'*
-'autoindent' 'ai'	boolean	(default off)
-			local to buffer
-	Copy indent from current line when starting a new line (typing <CR>
-	in Insert mode or when using the "o" or "O" command).  If you do not
-	type anything on the new line except <BS> or CTRL-D and then type
-	<Esc>, CTRL-O or <CR>, the indent is deleted again.  Moving the cursor
-	to another line has the same effect, unless the 'I' flag is included
-	in 'cpoptions'.
-	When autoindent is on, formatting (with the "gq" command or when you
-	reach 'textwidth' in Insert mode) uses the indentation of the first
-	line.
-	When 'smartindent' or 'cindent' is on the indent is changed in
-	a different way.
-	The 'autoindent' option is reset when the 'paste' option is set and
-	restored when 'paste' is reset.
-
-				 *'autoread'* *'ar'* *'noautoread'* *'noar'*
-'autoread' 'ar'		boolean	(default off)
-			global or local to buffer |global-local|
-	When a file has been detected to have been changed outside of Vim and
-	it has not been changed inside of Vim, automatically read it again.
-	When the file has been deleted this is not done, so you have the text
-	from before it was deleted.  When it appears again then it is read.
-	|timestamp|
-	If this option has a local value, use this command to switch back to
-	using the global value: >
-		:set autoread<
-<
-				 *'autowrite'* *'aw'* *'noautowrite'* *'noaw'*
-'autowrite' 'aw'	boolean	(default off)
-			global
-	Write the contents of the file, if it has been modified, on each
-	`:next`, `:rewind`, `:last`, `:first`, `:previous`, `:stop`,
-	`:suspend`, `:tag`, `:!`, `:make`, CTRL-] and CTRL-^ command; and when
-	a `:buffer`, CTRL-O, CTRL-I, '{A-Z0-9}, or `{A-Z0-9} command takes one
-	to another file.
-	A buffer is not written if it becomes hidden, e.g. when 'bufhidden' is
-	set to "hide" and `:next` is used.
-	Note that for some commands the 'autowrite' option is not used, see
-	'autowriteall' for that.
-	Some buffers will not be written, specifically when 'buftype' is
-	"nowrite", "nofile", "terminal" or "prompt".
-	USE WITH CARE: If you make temporary changes to a buffer that you
-	don't want to be saved this option may cause it to be saved anyway.
-	Renaming the buffer with ":file {name}" may help avoid this.
-
-			 *'autowriteall'* *'awa'* *'noautowriteall'* *'noawa'*
-'autowriteall' 'awa'	boolean	(default off)
-			global
-	Like 'autowrite', but also used for commands ":edit", ":enew", ":quit",
-	":qall", ":exit", ":xit", ":recover" and closing the Vim window.
-	Setting this option also implies that Vim behaves like 'autowrite' has
-	been set.
-
-							*'background'* *'bg'*
-'background' 'bg'	string	(default "dark" or "light", see below)
-			global
-	When set to "dark", Vim will try to use colors that look good on a
-	dark background.  When set to "light", Vim will try to use colors that
-	look good on a light background.  Any other value is illegal.
-	Vim tries to set the default value according to the terminal used.
-	This will not always be correct.
-	Setting this option does not change the background color, it tells Vim
-	what the background color looks like.  For changing the background
-	color, see |:hi-normal|.
-
-	When 'background' is set Vim will adjust the default color groups for
-	the new value.  But the colors used for syntax highlighting will not
-	change.					*g:colors_name*
-	When a color scheme is loaded (the "g:colors_name" variable is set)
-	setting 'background' will cause the color scheme to be reloaded.  If
-	the color scheme adjusts to the value of 'background' this will work.
-	However, if the color scheme sets 'background' itself the effect may
-	be undone.  First delete the "g:colors_name" variable when needed.
-
-	When setting 'background' to the default value with: >
-		:set background&
-<	Vim will guess the value.  In the GUI this should work correctly,
-	in other cases Vim might not be able to guess the right value.
-	If the GUI supports a dark theme, you can use the "d" flag in
-	'guioptions', see 'go-d'.
-
-	When the |t_RB| option is set, Vim will use it to request the background
-	color from the terminal.  If the returned RGB value is dark/light and
-	'background' is not dark/light, 'background' will be set and the
-	screen is redrawn.  This may have side effects, make t_BG empty in
-	your .vimrc if you suspect this problem.  The response to |t_RB| can
-	be found in |v:termrbgresp|.
-
-	When starting the GUI, the default value for 'background' will be
-	"light".  When the value is not set in the .gvimrc, and Vim detects
-	that the background is actually quite dark, 'background' is set to
-	"dark".  But this happens only AFTER the .gvimrc file has been read
-	(because the window needs to be opened to find the actual background
-	color).  To get around this, force the GUI window to be opened by
-	putting a ":gui" command in the .gvimrc file, before where the value
-	of 'background' is used (e.g., before ":syntax on").
-
-	For MS-Windows the default is "dark".
-	For other systems "dark" is used when 'term' is "linux",
-	"screen.linux", "cygwin" or "putty", or $COLORFGBG suggests a dark
-	background.  Otherwise the default is "light".
-
-	The |:terminal| command and the |term_start()| function use the
-	'background' value to decide whether the terminal window will start
-	with a white or black background.
-
-	Normally this option would be set in the .vimrc file.  Possibly
-	depending on the terminal name.  Example: >
-		:if &term == "pcterm"
-		:  set background=dark
-		:endif
-<	When this option is set, the default settings for the highlight groups
-	will change.  To use other settings, place ":highlight" commands AFTER
-	the setting of the 'background' option.
-	This option is also used in the "$VIMRUNTIME/syntax/syntax.vim" file
-	to select the colors for syntax highlighting.  After changing this
-	option, you must load syntax.vim again to see the result.  This can be
-	done with ":syntax on".
-
-							*'backspace'* *'bs'*
-'backspace' 'bs'	string	(default "", set to "indent,eol,start"
-							    in |defaults.vim|)
-			global
-	Influences the working of <BS>, <Del>, CTRL-W and CTRL-U in Insert
-	mode.  This is a list of items, separated by commas.  Each item allows
-	a way to backspace over something:
-	value	effect	~
-	indent	allow backspacing over autoindent
-	eol	allow backspacing over line breaks (join lines)
-	start	allow backspacing over the start of insert; CTRL-W and CTRL-U
-		stop once at the start of insert.
-	nostop	like start, except CTRL-W and CTRL-U do not stop at the start of
-		insert.
-
-	When the value is empty, Vi compatible backspacing is used, none of
-	the ways mentioned for the items above are possible.
-
-	For backwards compatibility with version 5.4 and earlier:
-	value	effect	~
-	  0	same as ":set backspace=" (Vi compatible)
-	  1	same as ":set backspace=indent,eol"
-	  2	same as ":set backspace=indent,eol,start"
-	  3	same as ":set backspace=indent,eol,nostop"
-
-	See |:fixdel| if your <BS> or <Del> key does not do what you want.
-	NOTE: This option is set to "" when 'compatible' is set.
-
-				*'backup'* *'bk'* *'nobackup'* *'nobk'*
-'backup' 'bk'		boolean	(default off)
-			global
-	Make a backup before overwriting a file.  Leave it around after the
-	file has been successfully written.  If you do not want to keep the
-	backup file, but you do want a backup while the file is being
-	written, reset this option and set the 'writebackup' option (this is
-	the default).  If you do not want a backup file at all reset both
-	options (use this if your file system is almost full).  See the
-	|backup-table| for more explanations.
-	When the 'backupskip' pattern matches, a backup is not made anyway.
-	When 'patchmode' is set, the backup may be renamed to become the
-	oldest version of a file.
-	NOTE: This option is reset when 'compatible' is set.
-
-						*'backupcopy'* *'bkc'*
-'backupcopy' 'bkc'	string	(Vi default for Unix: "yes", otherwise: "auto")
-			global or local to buffer |global-local|
-	When writing a file and a backup is made, this option tells how it's
-	done.  This is a comma-separated list of words.
-
-	The main values are:
-	"yes"	make a copy of the file and overwrite the original one
-	"no"	rename the file and write a new one
-	"auto"	one of the previous, what works best
-
-	Extra values that can be combined with the ones above are:
-	"breaksymlink"	always break symlinks when writing
-	"breakhardlink"	always break hardlinks when writing
-
-	Making a copy and overwriting the original file:
-	- Takes extra time to copy the file.
-	+ When the file has special attributes, is a (hard/symbolic) link or
-	  has a resource fork, all this is preserved.
-	- When the file is a link the backup will have the name of the link,
-	  not of the real file.
-
-	Renaming the file and writing a new one:
-	+ It's fast.
-	- Sometimes not all attributes of the file can be copied to the new
-	  file.
-	- When the file is a link the new file will not be a link.
-
-	The "auto" value is the middle way: When Vim sees that renaming the
-	file is possible without side effects (the attributes can be passed on
-	and the file is not a link) that is used.  When problems are expected,
-	a copy will be made.
-
-	The "breaksymlink" and "breakhardlink" values can be used in
-	combination with any of "yes", "no" and "auto".  When included, they
-	force Vim to always break either symbolic or hard links by doing
-	exactly what the "no" option does, renaming the original file to
-	become the backup and writing a new file in its place.  This can be
-	useful for example in source trees where all the files are symbolic or
-	hard links and any changes should stay in the local source tree, not
-	be propagated back to the original source.
-							*crontab*
-	One situation where "no" and "auto" will cause problems: A program
-	that opens a file, invokes Vim to edit that file, and then tests if
-	the open file was changed (through the file descriptor) will check the
-	backup file instead of the newly created file.  "crontab -e" is an
-	example.
-
-	When a copy is made, the original file is truncated and then filled
-	with the new text.  This means that protection bits, owner and
-	symbolic links of the original file are unmodified.  The backup file,
-	however, is a new file, owned by the user who edited the file.  The
-	group of the backup is set to the group of the original file.  If this
-	fails, the protection bits for the group are made the same as for
-	others.
-
-	When the file is renamed, this is the other way around: The backup has
-	the same attributes of the original file, and the newly written file
-	is owned by the current user.  When the file was a (hard/symbolic)
-	link, the new file will not!  That's why the "auto" value doesn't
-	rename when the file is a link.  The owner and group of the newly
-	written file will be set to the same ones as the original file, but
-	the system may refuse to do this.  In that case the "auto" value will
-	again not rename the file.
-
-	NOTE: This option is set to the Vi default value when 'compatible' is
-	set and to the Vim default value when 'compatible' is reset.
-
-						*'backupdir'* *'bdir'*
-'backupdir' 'bdir'	string	(default for Amiga: ".,t:",
-				 for Win32: ".,$TEMP,c:/tmp,c:/temp"
-				 for Unix: ".,~/tmp,~/")
-			global
-	List of directories for the backup file, separated with commas.
-	- The backup file will be created in the first directory in the list
-	  where this is possible.  The directory must exist, Vim will not
-	  create it for you.
-	- Empty means that no backup file will be created ('patchmode' is
-	  impossible!).  Writing may fail because of this.
-	- A directory "." means to put the backup file in the same directory
-	  as the edited file.
-	- A directory starting with "./" (or ".\" for MS-Windows) means to put
-	  the backup file relative to where the edited file is.  The leading
-	  "." is replaced with the path name of the edited file.
-	  ("." inside a directory name has no special meaning).
-	- Spaces after the comma are ignored, other spaces are considered part
-	  of the directory name.  To have a space at the start of a directory
-	  name, precede it with a backslash.
-	- To include a comma in a directory name precede it with a backslash.
-	- A directory name may end in an '/'.
-	- For Unix and Win32, if a directory ends in two path separators "//",
-	  the backup file name will be built from the complete path to the
-	  file with all path separators changed to percent '%' signs. This
-	  will ensure file name uniqueness in the backup directory.
-	  On Win32, it is also possible to end with "\\".  However, When a
-	  separating comma is following, you must use "//", since "\\" will
-	  include the comma in the file name. Therefore it is recommended to
-	  use '//', instead of '\\'.
-	- Environment variables are expanded |:set_env|.
-	- Careful with '\' characters, type one before a space, type two to
-	  get one in the option (see |option-backslash|), for example: >
-	    :set bdir=c:\\tmp,\ dir\\,with\\,commas,\\\ dir\ with\ spaces
-<	- For backwards compatibility with Vim version 3.0 a '>' at the start
-	  of the option is removed.
-	See also 'backup' and 'writebackup' options.
-	If you want to hide your backup files on Unix, consider this value: >
-		:set backupdir=./.backup,~/.backup,.,/tmp
-<	You must create a ".backup" directory in each directory and in your
-	home directory for this to work properly.
-	The use of |:set+=| and |:set-=| is preferred when adding or removing
-	directories from the list.  This avoids problems when a future version
-	uses another default.
-	This option cannot be set from a |modeline| or in the |sandbox|, for
-	security reasons.
-
-						*'backupext'* *'bex'* *E589*
-'backupext' 'bex'	string	(default "~", for VMS: "_")
-			global
-	String which is appended to a file name to make the name of the
-	backup file.  The default is quite unusual, because this avoids
-	accidentally overwriting existing files with a backup file.  You might
-	prefer using ".bak", but make sure that you don't have files with
-	".bak" that you want to keep.
-	Only normal file name characters can be used; "/\*?[|<>" are illegal.
-
-	If you like to keep a lot of backups, you could use a BufWritePre
-	autocommand to change 'backupext' just before writing the file to
-	include a timestamp. >
-		:au BufWritePre * let &bex = '-' .. strftime("%Y%b%d%X") .. '~'
-<	Use 'backupdir' to put the backup in a different directory.
-
-						*'backupskip'* *'bsk'*
-'backupskip' 'bsk'	string	(default: "$TMPDIR/*,$TMP/*,$TEMP/*"
-				 Unix: "/tmp/*,$TMPDIR/*,$TMP/*,$TEMP/*"
-				 Mac: "/private/tmp/*,$TMPDIR/*,$TMP/*,$TEMP/*")
-			global
-	A list of file patterns.  When one of the patterns matches with the
-	name of the file which is written, no backup file is created.  Both
-	the specified file name and the full path name of the file are used.
-	The pattern is used like with |:autocmd|, see |autocmd-patterns|.
-	Watch out for special characters, see |option-backslash|.
-	When $TMPDIR, $TMP or $TEMP is not defined, it is not used for the
-	default value.  "/tmp/*" is only used for Unix.
-
-	WARNING: Not having a backup file means that when Vim fails to write
-	your buffer correctly and then, for whatever reason, Vim exits, you
-	lose both the original file and what you were writing.  Only disable
-	backups if you don't care about losing the file.
-
-	Note that environment variables are not expanded.  If you want to use
-	$HOME you must expand it explicitly, e.g.: >
-		:let &backupskip = escape(expand('$HOME'), '\') .. '/tmp/*'
-
-<	Note that the default also makes sure that "crontab -e" works (when a
-	backup would be made by renaming the original file crontab won't see
-	the newly created file).  Also see 'backupcopy' and |crontab|.
-
-						*'balloondelay'* *'bdlay'*
-'balloondelay' 'bdlay'	number	(default: 600)
-			global
-			{only available when compiled with the |+balloon_eval|
-			feature}
-	Delay in milliseconds before a balloon may pop up.  See |balloon-eval|.
-
-		       *'ballooneval'* *'beval'* *'noballooneval'* *'nobeval'*
-'ballooneval' 'beval'	boolean	(default off)
-			global
-			{only available when compiled with the |+balloon_eval|
-			feature}
-	Switch on the |balloon-eval| functionality for the GUI.
-
-		       *'balloonevalterm'* *'bevalterm'* *'noballoonevalterm'*
-		       *'nobevalterm'*
-'balloonevalterm' 'bevalterm'	boolean	(default off)
-			global
-			{only available when compiled with the
-			|+balloon_eval_term| feature}
-	Switch on the |balloon-eval| functionality for the terminal.
-
-						     *'balloonexpr'* *'bexpr'*
-'balloonexpr' 'bexpr'	string	(default "")
-			global or local to buffer |global-local|
-			{only available when compiled with the |+balloon_eval|
-			feature}
-	Expression for text to show in evaluation balloon.  It is only used
-	when 'ballooneval' or 'balloonevalterm' is on.  These variables can be
-	used:
-
-	v:beval_bufnr	number of the buffer in which balloon is going to show
-	v:beval_winnr	number of the window
-	v:beval_winid	ID of the window
-	v:beval_lnum	line number
-	v:beval_col	column number (byte index)
-	v:beval_text	word under or after the mouse pointer
-
-	Instead of showing a balloon, which is limited to plain text, consider
-	using a popup window, see |popup_beval_example|.  A popup window can
-	use highlighting and show a border.
-
-	The evaluation of the expression must not have side effects!
-	Example: >
-    function MyBalloonExpr()
-	return 'Cursor is at line ' .. v:beval_lnum ..
-		\ ', column ' .. v:beval_col ..
-		\ ' of file ' ..  bufname(v:beval_bufnr) ..
-		\ ' on word "' .. v:beval_text .. '"'
-    endfunction
-    set bexpr=MyBalloonExpr()
-    set ballooneval balloonevalterm
-<
-	Also see |balloon_show()|, it can be used if the content of the balloon
-	is to be fetched asynchronously.  In that case evaluating
-	'balloonexpr' should result in an empty string.  If you get a balloon
-	with only "0" you probably didn't return anything from your function.
-
-	NOTE: The balloon is displayed only if the cursor is on a text
-	character.  If the result of evaluating 'balloonexpr' is not empty,
-	Vim does not try to send a message to an external debugger (Netbeans
-	or Sun Workshop).
-
-	If the expression starts with s: or |<SID>|, then it is replaced with
-	the script ID (|local-function|). Example: >
-		set bexpr=s:MyBalloonExpr()
-		set bexpr=<SID>SomeBalloonExpr()
-<	Otherwise, the expression is evaluated in the context of the script
-	where the option was set, thus script-local items are available.
-
-	The expression will be evaluated in the |sandbox| when set from a
-	modeline, see |sandbox-option|.
-	This option cannot be set in a modeline when 'modelineexpr' is off.
-
-	It is not allowed to change text or jump to another window while
-	evaluating 'balloonexpr', see |textlock|.
-
-	To check whether line breaks in the balloon text work use this check: >
-		if has("balloon_multiline")
-<	When they are supported "\n" characters will start a new line.  If the
-	expression evaluates to a |List| this is equal to using each List item
-	as a string and putting "\n" in between them.
-	NOTE: This option is set to "" when 'compatible' is set.
-
-						*'belloff'* *'bo'*
-'belloff' 'bo'		string	(default "")
-			global
-	Specifies for which events the bell will not be rung. It is a comma
-	separated list of items. For each item that is present, the bell
-	will be silenced. This is most useful to specify specific events in
-	insert mode to be silenced.
-	You can also make it flash by using 'visualbell'.
-
-	item	    meaning when present	~
-	all	    All events.
-	backspace   When hitting <BS> or <Del> and deleting results in an
-		    error.
-	cursor	    Fail to move around using the cursor keys or
-		    <PageUp>/<PageDown> in |Insert-mode|.
-	complete    Error occurred when using |i_CTRL-X_CTRL-K| or
-		    |i_CTRL-X_CTRL-T|.
-	copy	    Cannot copy char from insert mode using |i_CTRL-Y| or
-		    |i_CTRL-E|.
-	ctrlg	    Unknown Char after <C-G> in Insert mode.
-	error	    Other Error occurred (e.g. try to join last line)
-		    (mostly used in |Normal-mode| or |Cmdline-mode|).
-	esc	    hitting <Esc> in |Normal-mode|.
-	ex	    In |Visual-mode|, hitting |Q| results in an error.
-	hangul	    Ignored.
-	insertmode  Pressing <Esc> in 'insertmode'.
-	lang	    Calling the beep module for Lua/Mzscheme/TCL.
-	mess	    No output available for |g<|.
-	showmatch   Error occurred for 'showmatch' function.
-	operator    Empty region error |cpo-E|.
-	register    Unknown register after <C-R> in |Insert-mode|.
-	shell	    Bell from shell output |:!|.
-	spell	    Error happened on spell suggest.
-	term	    Bell from |:terminal| output.
-	wildmode    More matches in |cmdline-completion| available
-		    (depends on the 'wildmode' setting).
-
-	This is most useful to fine tune when in Insert mode the bell should
-	be rung. For Normal mode and Ex commands, the bell is often rung to
-	indicate that an error occurred. It can be silenced by adding the
-	"error" keyword.
-
-				     *'binary'* *'bin'* *'nobinary'* *'nobin'*
-'binary' 'bin'		boolean	(default off)
-			local to buffer
-	This option should be set before editing a binary file.  You can also
-	use the |-b| Vim argument.  When this option is switched on a few
-	options will be changed (also when it already was on):
-		'textwidth'  will be set to 0
-		'wrapmargin' will be set to 0
-		'modeline'   will be off
-		'expandtab'  will be off
-	Also, 'fileformat' and 'fileformats' options will not be used, the
-	file is read and written like 'fileformat' was "unix" (a single <NL>
-	separates lines).
-	The 'fileencoding' and 'fileencodings' options will not be used, the
-	file is read without conversion.
-	NOTE: When you start editing a(nother) file while the 'bin' option is
-	on, settings from autocommands may change the settings again (e.g.,
-	'textwidth'), causing trouble when editing.  You might want to set
-	'bin' again when the file has been loaded.
-	The previous values of these options are remembered and restored when
-	'bin' is switched from on to off.  Each buffer has its own set of
-	saved option values.
-	To edit a file with 'binary' set you can use the |++bin| argument.
-	This avoids you have to do ":set bin", which would have effect for all
-	files you edit.
-	When writing a file the <EOL> for the last line is only written if
-	there was one in the original file (normally Vim appends an <EOL> to
-	the last line if there is none; this would make the file longer).  See
-	the 'endofline' option.
-
-			*'bioskey'* *'biosk'* *'nobioskey'* *'nobiosk'*
-'bioskey' 'biosk'	boolean	(default on)
-			global
-			{only for MS-DOS}
-	This was for MS-DOS and is no longer supported.
-
-							*'bomb'* *'nobomb'*
-'bomb'			boolean	(default off)
-			local to buffer
-	When writing a file and the following conditions are met, a BOM (Byte
-	Order Mark) is prepended to the file:
-	- this option is on
-	- the 'binary' option is off
-	- 'fileencoding' is "utf-8", "ucs-2", "ucs-4" or one of the little/big
-	  endian variants.
-	Some applications use the BOM to recognize the encoding of the file.
-	Often used for UCS-2 files on MS-Windows.  For other applications it
-	causes trouble, for example: "cat file1 file2" makes the BOM of file2
-	appear halfway the resulting file.  Gcc doesn't accept a BOM.
-	When Vim reads a file and 'fileencodings' starts with "ucs-bom", a
-	check for the presence of the BOM is done and 'bomb' set accordingly.
-	Unless 'binary' is set, it is removed from the first line, so that you
-	don't see it when editing.  When you don't change the options, the BOM
-	will be restored when writing the file.
-
-						*'breakat'* *'brk'*
-'breakat' 'brk'		string	(default " ^I!@*-+;:,./?")
-			global
-			{not available when compiled without the |+linebreak|
-			feature}
-	This option lets you choose which characters might cause a line
-	break if 'linebreak' is on.  Only works for ASCII and also for 8-bit
-	characters when 'encoding' is an 8-bit encoding.
-
-			*'breakindent'* *'bri'* *'nobreakindent'* *'nobri'*
-'breakindent' 'bri'	boolean (default off)
-			local to window
-			{not available when compiled without the |+linebreak|
-			feature}
-	Every wrapped line will continue visually indented (same amount of
-	space as the beginning of that line), thus preserving horizontal blocks
-	of text.
-	NOTE: This option is reset when 'compatible' is set.
-
-						*'breakindentopt'* *'briopt'*
-'breakindentopt' 'briopt' string (default empty)
-			local to window
-			{not available when compiled without the |+linebreak|
-			feature}
-	Settings for 'breakindent'. It can consist of the following optional
-	items and must be separated by a comma:
-		min:{n}	    Minimum text width that will be kept after
-			    applying 'breakindent', even if the resulting
-			    text should normally be narrower. This prevents
-			    text indented almost to the right window border
-			    occupying lot of vertical space when broken.
-			    (default: 20)
-		shift:{n}   After applying 'breakindent', the wrapped line's
-			    beginning will be shifted by the given number of
-			    characters.  It permits dynamic French paragraph
-			    indentation (negative) or emphasizing the line
-			    continuation (positive).
-			    (default: 0)
-		sbr	    Display the 'showbreak' value before applying the
-			    additional indent.
-			    (default: off)
-		list:{n}    Adds an additional indent for lines that match a
-			    numbered or bulleted list (using the
-			    'formatlistpat' setting).
-		list:-1	    Uses the length of a match with 'formatlistpat'
-			    for indentation.
-			    (default: 0)
-		column:{n}  Indent at column {n}. Will overrule the other
-			    sub-options. Note: an additional indent may be
-			    added for the 'showbreak' setting.
-			    (default: off)
-
-						*'browsedir'* *'bsdir'*
-'browsedir' 'bsdir'	string	(default: "last")
-			global
-			{only for Motif, GTK, Mac and Win32 GUI}
-	Which directory to use for the file browser:
-	   last		Use same directory as with last file browser, where a
-			file was opened or saved.
-	   buffer	Use the directory of the related buffer.
-	   current	Use the current directory.
-	   {path}	Use the specified directory
-
-						*'bufhidden'* *'bh'*
-'bufhidden' 'bh'	string (default: "")
-			local to buffer
-	This option specifies what happens when a buffer is no longer
-	displayed in a window:
-	  <empty>	follow the global 'hidden' option
-	  hide		hide the buffer (don't unload it), even if 'hidden' is
-			not set
-	  unload	unload the buffer, even if 'hidden' is set; the
-			|:hide| command will also unload the buffer
-	  delete	delete the buffer from the buffer list, even if
-			'hidden' is set; the |:hide| command will also delete
-			the buffer, making it behave like |:bdelete|
-	  wipe		wipe the buffer from the buffer list, even if
-			'hidden' is set; the |:hide| command will also wipe
-			out the buffer, making it behave like |:bwipeout|
-
-	CAREFUL: when "unload", "delete" or "wipe" is used changes in a buffer
-	are lost without a warning.  Also, these values may break autocommands
-	that switch between buffers temporarily.
-	This option is used together with 'buftype' and 'swapfile' to specify
-	special kinds of buffers.   See |special-buffers|.
-
-			*'buflisted'* *'bl'* *'nobuflisted'* *'nobl'* *E85*
-'buflisted' 'bl'	boolean (default: on)
-			local to buffer
-	When this option is set, the buffer shows up in the buffer list.  If
-	it is reset it is not used for ":bnext", "ls", the Buffers menu, etc.
-	This option is reset by Vim for buffers that are only used to remember
-	a file name or marks.  Vim sets it when starting to edit a buffer.
-	But not when moving to a buffer with ":buffer".
-
-						*'buftype'* *'bt'* *E382*
-'buftype' 'bt'		string (default: "")
-			local to buffer
-	The value of this option specifies the type of a buffer:
-	  <empty>	normal buffer
-	  nofile	buffer which is not related to a file and will not be
-			written
-	  nowrite	buffer which will not be written
-	  acwrite	buffer which will always be written with BufWriteCmd
-			autocommands.
-	  quickfix	quickfix buffer, contains list of errors |:cwindow|
-			or list of locations |:lwindow|
-	  help		help buffer (you are not supposed to set this
-			manually)
-	  terminal	buffer for a |terminal| (you are not supposed to set
-			this manually)
-	  prompt	buffer where only the last line can be edited, meant
-			to be used by a plugin, see |prompt-buffer|
-			{only when compiled with the |+channel| feature}
-	  popup		buffer used in a popup window, see |popup|.
-			{only when compiled with the |+textprop| feature}
-
-	This option is used together with 'bufhidden' and 'swapfile' to
-	specify special kinds of buffers.   See |special-buffers|.
-	Also see |win_gettype()|, which returns the type of the window.
-
-	Be careful with changing this option, it can have many side effects!
-	One such effect is that Vim will not check the timestamp of the file,
-	if the file is changed by another program this will not be noticed.
-
-	A "quickfix" buffer is only used for the error list and the location
-	list.  This value is set by the |:cwindow| and |:lwindow| commands and
-	you are not supposed to change it.
-
-	"nofile" and "nowrite" buffers are similar:
-	both:		The buffer is not to be written to disk, ":w" doesn't
-			work (":w filename" does work though).
-	both:		The buffer is never considered to be |'modified'|.
-			There is no warning when the changes will be lost, for
-			example when you quit Vim.
-	both:		A swap file is only created when using too much memory
-			(when 'swapfile' has been reset there is never a swap
-			file).
-	nofile only:	The buffer name is fixed, it is not handled like a
-			file name.  It is not modified in response to a |:cd|
-			command.
-	both:		When using ":e bufname" and already editing "bufname"
-			the buffer is made empty and autocommands are
-			triggered as usual for |:edit|.
-							*E676*
-	"acwrite" implies that the buffer name is not related to a file, like
-	"nofile", but it will be written.  Thus, in contrast to "nofile" and
-	"nowrite", ":w" does work and a modified buffer can't be abandoned
-	without saving.  For writing there must be matching |BufWriteCmd|,
-	|FileWriteCmd| or |FileAppendCmd| autocommands.
-
-						*'casemap'* *'cmp'*
-'casemap' 'cmp'		string	(default: "internal,keepascii")
-			global
-	Specifies details about changing the case of letters.  It may contain
-	these words, separated by a comma:
-	internal	Use internal case mapping functions, the current
-			locale does not change the case mapping.  This only
-			matters when 'encoding' is a Unicode encoding,
-			"latin1" or "iso-8859-15".  When "internal" is
-			omitted, the towupper() and towlower() system library
-			functions are used when available.
-	keepascii	For the ASCII characters (0x00 to 0x7f) use the US
-			case mapping, the current locale is not effective.
-			This probably only matters for Turkish.
-
-				*'cdhome'* *'cdh'* *'nocdhome'* *'nocdh'*
-'cdhome' 'cdh'		boolean	(default: off)
-			global
-	When on, |:cd|, |:tcd| and |:lcd| without an argument changes the
-	current working directory to the |$HOME| directory like in Unix.
-	When off, those commands just print the current directory name.
-	On Unix this option has no effect.
-	NOTE: This option is reset when 'compatible' is set.
-
-						*'cdpath'* *'cd'* *E344* *E346*
-'cdpath' 'cd'		string	(default: equivalent to $CDPATH or ",,")
-			global
-	This is a list of directories which will be searched when using the
-	|:cd|, |:tcd| and |:lcd| commands, provided that the directory being
-	searched for has a relative path, not an absolute part starting with
-	"/", "./" or "../", the 'cdpath' option is not used then.
-	The 'cdpath' option's value has the same form and semantics as
-	|'path'|.  Also see |file-searching|.
-	The default value is taken from $CDPATH, with a "," prepended to look
-	in the current directory first.
-	If the default value taken from $CDPATH is not what you want, include
-	a modified version of the following command in your vimrc file to
-	override it: >
-	  :let &cdpath = ',' .. substitute(substitute($CDPATH, '[, ]', '\\\0', 'g'), ':', ',', 'g')
-<	This option cannot be set from a |modeline| or in the |sandbox|, for
-	security reasons.
-	(parts of 'cdpath' can be passed to the shell to expand file names).
-
-						*'cedit'*
-'cedit'			string	(Vi default: "", Vim default: CTRL-F)
-			global
-	The key used in Command-line Mode to open the command-line window.
-	The default is CTRL-F when 'compatible' is off.
-	Only non-printable keys are allowed.
-	The key can be specified as a single character, but it is difficult to
-	type.  The preferred way is to use the <> notation.  Examples: >
-		:exe "set cedit=\<C-Y>"
-		:exe "set cedit=\<Esc>"
-<	|Nvi| also has this option, but it only uses the first character.
-	See |cmdwin|.
-	NOTE: This option is set to the Vim default value when 'compatible'
-	is reset.
-
-				*'charconvert'* *'ccv'* *E202* *E214* *E513*
-'charconvert' 'ccv'	string (default "")
-			global
-			{only available when compiled with the |+eval| feature}
-	An expression that is used for character encoding conversion.  It is
-	evaluated when a file that is to be read or has been written has a
-	different encoding from what is desired.
-	'charconvert' is not used when the internal iconv() function is
-	supported and is able to do the conversion.  Using iconv() is
-	preferred, because it is much faster.
-	'charconvert' is not used when reading stdin |--|, because there is no
-	file to convert from.  You will have to save the text in a file first.
-	The expression must return zero, false or an empty string for success,
-	non-zero or true for failure.
-	The possible encoding names encountered are in 'encoding'.
-	Additionally, names given in 'fileencodings' and 'fileencoding' are
-	used.
-	Conversion between "latin1", "unicode", "ucs-2", "ucs-4" and "utf-8"
-	is done internally by Vim, 'charconvert' is not used for this.
-	'charconvert' is also used to convert the viminfo file, if the 'c'
-	flag is present in 'viminfo'.  Also used for Unicode conversion.
-	Example: >
-		set charconvert=CharConvert()
-		fun CharConvert()
-		  system("recode "
-			\ .. v:charconvert_from .. ".." .. v:charconvert_to
-			\ .. " <" .. v:fname_in .. " >" .. v:fname_out)
-		  return v:shell_error
-		endfun
-<	The related Vim variables are:
-		v:charconvert_from	name of the current encoding
-		v:charconvert_to	name of the desired encoding
-		v:fname_in		name of the input file
-		v:fname_out		name of the output file
-	Note that v:fname_in and v:fname_out will never be the same.
-	Note that v:charconvert_from and v:charconvert_to may be different
-	from 'encoding'.  Vim internally uses UTF-8 instead of UCS-2 or UCS-4.
-
-	The advantage of using a function call without arguments is that it is
-	faster, see |expr-option-function|.
-
-	Encryption is not done by Vim when using 'charconvert'.  If you want
-	to encrypt the file after conversion, 'charconvert' should take care
-	of this.
-
-	If the 'charconvert' expression starts with s: or |<SID>|, then it is
-	replaced with the script ID (|local-function|). Example: >
-		set charconvert=s:MyConvert()
-		set charconvert=<SID>SomeConvert()
-<	Otherwise the expression is evaluated in the context of the script
-	where the option was set, thus script-local items are available.
-
-	This option cannot be set from a |modeline| or in the |sandbox|, for
-	security reasons.
-
-				   *'cindent'* *'cin'* *'nocindent'* *'nocin'*
-'cindent' 'cin'		boolean	(default off)
-			local to buffer
-	Enables automatic C program indenting.  See 'cinkeys' to set the keys
-	that trigger reindenting in insert mode and 'cinoptions' to set your
-	preferred indent style.
-	If 'indentexpr' is not empty, it overrules 'cindent'.
-	If 'lisp' is not on and both 'indentexpr' and 'equalprg' are empty,
-	the "=" operator indents using this algorithm rather than calling an
-	external program.
-	See |C-indenting|.
-	When you don't like the way 'cindent' works, try the 'smartindent'
-	option or 'indentexpr'.
-	This option is not used when 'paste' is set.
-	NOTE: This option is reset when 'compatible' is set.
-
-							*'cinkeys'* *'cink'*
-'cinkeys' 'cink'	string	(default "0{,0},0),0],:,0#,!^F,o,O,e")
-			local to buffer
-	A list of keys that, when typed in Insert mode, cause reindenting of
-	the current line.  Only used if 'cindent' is on and 'indentexpr' is
-	empty.
-	For the format of this option see |cinkeys-format|.
-	See |C-indenting|.
-
-						*'cinoptions'* *'cino'*
-'cinoptions' 'cino'	string	(default "")
-			local to buffer
-	The 'cinoptions' affect the way 'cindent' reindents lines in a C
-	program.  See |cinoptions-values| for the values of this option, and
-	|C-indenting| for info on C indenting in general.
-
-
-						*'cinwords'* *'cinw'*
-'cinwords' 'cinw'	string	(default "if,else,while,do,for,switch")
-			local to buffer
-	These keywords start an extra indent in the next line when
-	'smartindent' or 'cindent' is set.  For 'cindent' this is only done at
-	an appropriate place (inside {}).
-	Note that 'ignorecase' isn't used for 'cinwords'.  If case doesn't
-	matter, include the keyword both the uppercase and lowercase:
-	"if,If,IF".
-
-						*'cinscopedecls'* *'cinsd'*
-'cinscopedecls' 'cinsd'	string	(default "public,protected,private")
-			local to buffer
-	Keywords that are interpreted as a C++ scope declaration by |cino-g|.
-	Useful e.g. for working with the Qt framework that defines additional
-	scope declarations "signals", "public slots" and "private slots": >
-		set cinscopedecls+=signals,public\ slots,private\ slots
-
-<						*'clipboard'* *'cb'*
-'clipboard' 'cb'	string	(default "autoselect,exclude:cons\|linux"
-						  for X-windows, "" otherwise)
-			global
-			{only in GUI versions or when the |+xterm_clipboard|
-			feature is included}
-	This option is a list of comma-separated names.
-	Note: if one of the items is "exclude:", then you can't add an item
-	after that.  Therefore do not append an item with += but use ^= to
-	prepend, e.g.: >
-		set clipboard^=unnamed
-<	When using the GUI see |'go-A'|.
-	These names are recognized:
-
-						*clipboard-unnamed*
-	unnamed		When included, Vim will use the clipboard register '*'
-			for all yank, delete, change and put operations which
-			would normally go to the unnamed register.  When a
-			register is explicitly specified, it will always be
-			used regardless of whether "unnamed" is in 'clipboard'
-			or not.  The clipboard register can always be
-			explicitly accessed using the "* notation.  Also see
-			|gui-clipboard|.
-
-						*clipboard-unnamedplus*
-	unnamedplus	A variant of the "unnamed" flag which uses the
-			clipboard register '+' (|quoteplus|) instead of
-			register '*' for all yank, delete, change and put
-			operations which would normally go to the unnamed
-			register.  When "unnamed" is also included to the
-			option, yank operations (but not delete, change or
-			put) will additionally copy the text into register
-			'*'.
-			Only available with the |+X11| feature.
-			Availability can be checked with: >
-				if has('unnamedplus')
-<
-						*clipboard-autoselect*
-	autoselect	Works like the 'a' flag in 'guioptions': If present,
-			then whenever Visual mode is started, or the Visual
-			area extended, Vim tries to become the owner of the
-			windowing system's global selection or put the
-			selected text on the clipboard used by the selection
-			register "*.  See |'go-a'| and |quotestar| for details.
-			When the GUI is active, the 'a' flag in 'guioptions'
-			is used, when the GUI is not active, this "autoselect"
-			flag is used.
-			Also applies to the modeless selection.
-
-						*clipboard-autoselectplus*
-	autoselectplus  Like "autoselect" but using the + register instead of
-			the * register.  Compare to the 'P' flag in
-			'guioptions'.
-
-						*clipboard-autoselectml*
-	autoselectml	Like "autoselect", but for the modeless selection
-			only.  Compare to the 'A' flag in 'guioptions'.
-
-						*clipboard-html*
-	html		When the clipboard contains HTML, use this when
-			pasting.  When putting text on the clipboard, mark it
-			as HTML.  This works to copy rendered HTML from
-			Firefox, paste it as raw HTML in Vim, select the HTML
-			in Vim and paste it in a rich edit box in Firefox.
-			You probably want to add this only temporarily,
-			possibly use BufEnter autocommands.
-			Only supported for GTK version 2 and later.
-
-						*clipboard-exclude*
-	exclude:{pattern}
-			Defines a pattern that is matched against the name of
-			the terminal 'term'.  If there is a match, no
-			connection will be made to the X server.  This is
-			useful in this situation:
-			- Running Vim in a console.
-			- $DISPLAY is set to start applications on another
-			  display.
-			- You do not want to connect to the X server in the
-			  console, but do want this in a terminal emulator.
-			To never connect to the X server use: >
-				exclude:.*
-<			This has the same effect as using the |-X| argument.
-			Note that when there is no connection to the X server
-			the window title won't be restored and the clipboard
-			cannot be accessed.
-			The value of 'magic' is ignored, {pattern} is
-			interpreted as if 'magic' was on.
-			The rest of the option value will be used for
-			{pattern}, this must be the last entry.
-
-						*'cmdheight'* *'ch'*
-'cmdheight' 'ch'	number	(default 1)
-			global or local to tab page
-	Number of screen lines to use for the command-line.  A larger value
-	helps avoiding |hit-enter| prompts.
-	The value of this option is stored with the tab page, so that each tab
-	page can have a different value.
-
-						*'cmdwinheight'* *'cwh'*
-'cmdwinheight' 'cwh'	number	(default 7)
-			global
-	Number of screen lines to use for the command-line window. |cmdwin|
-
-						*'colorcolumn'* *'cc'*
-'colorcolumn' 'cc'	string	(default "")
-			local to window
-			{not available when compiled without the |+syntax|
-			feature}
-	'colorcolumn' is a comma-separated list of screen columns that are
-	highlighted with ColorColumn |hl-ColorColumn|.  Useful to align
-	text.  Will make screen redrawing slower.
-	The screen column can be an absolute number, or a number preceded with
-	'+' or '-', which is added to or subtracted from 'textwidth'. >
-
-		:set cc=+1	  " highlight column after 'textwidth'
-		:set cc=+1,+2,+3  " highlight three columns after 'textwidth'
-		:hi ColorColumn ctermbg=lightgrey guibg=lightgrey
-<
-	When 'textwidth' is zero then the items with '-' and '+' are not used.
-	A maximum of 256 columns are highlighted.
-
-						*'columns'* *'co'* *E594*
-'columns' 'co'		number	(default 80 or terminal width)
-			global
-	Number of columns of the screen.  Normally this is set by the terminal
-	initialization and does not have to be set by hand.  Also see
-	|posix-screen-size|.
-	When Vim is running in the GUI or in a resizable window, setting this
-	option will cause the window size to be changed.  When you only want
-	to use the size for the GUI, put the command in your |gvimrc| file.
-	When you set this option and Vim is unable to change the physical
-	number of columns of the display, the display may be messed up.  For
-	the GUI it is always possible and Vim limits the number of columns to
-	what fits on the screen.  You can use this command to get the widest
-	window possible: >
-		:set columns=9999
-<	Minimum value is 12, maximum value is 10000.
-
-					*'comments'* *'com'* *E524* *E525*
-'comments' 'com'	string	(default
-				"s1:/*,mb:*,ex:*/,://,b:#,:%,:XCOMM,n:>,fb:-")
-			local to buffer
-	A comma-separated list of strings that can start a comment line.  See
-	|format-comments|.  See |option-backslash| about using backslashes to
-	insert a space.
-
-					*'commentstring'* *'cms'* *E537*
-'commentstring' 'cms'	string	(default "/*%s*/")
-			local to buffer
-			{not available when compiled without the |+folding|
-			feature}
-	A template for a comment.  The "%s" in the value is replaced with the
-	comment text.  Currently only used to add markers for folding, see
-	|fold-marker|.
-
-			*'compatible'* *'cp'* *'nocompatible'* *'nocp'*
-'compatible' 'cp'	boolean	(default on, off when a |vimrc| or |gvimrc|
-					file is found, reset in |defaults.vim|)
-			global
-	This option has the effect of making Vim either more Vi-compatible, or
-	make Vim behave in a more useful way.
-
-	This is a special kind of option, because when it's set or reset,
-	other options are also changed as a side effect.
-	NOTE: Setting or resetting this option can have a lot of unexpected
-	effects: Mappings are interpreted in another way, undo behaves
-	differently, etc.  If you set this option in your vimrc file, you
-	should probably put it at the very start.
-
-	By default this option is on and the Vi defaults are used for the
-	options.  This default was chosen for those people who want to use Vim
-	just like Vi, and don't even (want to) know about the 'compatible'
-	option.
-	When a |vimrc| or |gvimrc| file is found while Vim is starting up,
-	this option is switched off, and all options that have not been
-	modified will be set to the Vim defaults.  Effectively, this means
-	that when a |vimrc| or |gvimrc| file exists, Vim will use the Vim
-	defaults, otherwise it will use the Vi defaults.  (Note: This doesn't
-	happen for the system-wide vimrc or gvimrc file, nor for a file given
-	with the |-u| argument).  Also see |compatible-default| and
-	|posix-compliance|.
-	You can also set this option with the "-C" argument, and reset it with
-	"-N".  See |-C| and |-N|.
-	See 'cpoptions' for more fine tuning of Vi compatibility.
-
-	When this option is set, numerous other options are set to make Vim as
-	Vi-compatible as possible.  When this option is unset, various options
-	are set to make Vim more useful.  The table below lists all the
-	options affected.
-	The {?} column indicates when the options are affected:
-	+  Means that the option is set to the value given in {set value} when
-	   'compatible' is set.
-	&  Means that the option is set to the value given in {set value} when
-	   'compatible' is set AND is set to its Vim default value when
-	   'compatible' is unset.
-	-  Means the option is NOT changed when setting 'compatible' but IS
-	   set to its Vim default when 'compatible' is unset.
-	The {effect} column summarises the change when 'compatible' is set.

-
-						*'complete'* *'cpt'* *E535*
-'complete' 'cpt'	string	(default: ".,w,b,u,t,i")
-			local to buffer
-	This option specifies how keyword completion |ins-completion| works
-	when CTRL-P or CTRL-N are used.  It is also used for whole-line
-	completion |i_CTRL-X_CTRL-L|.  It indicates the type of completion
-	and the places to scan.  It is a comma-separated list of flags:
-	.	scan the current buffer ('wrapscan' is ignored)
-	w	scan buffers from other windows
-	b	scan other loaded buffers that are in the buffer list
-	u	scan the unloaded buffers that are in the buffer list
-	U	scan the buffers that are not in the buffer list
-	k	scan the files given with the 'dictionary' option
-	kspell  use the currently active spell checking |spell|
-	k{dict}	scan the file {dict}.  Several "k" flags can be given,
-		patterns are valid too.  For example: >
-			:set cpt=k/usr/dict/*,k~/spanish
-<	s	scan the files given with the 'thesaurus' option
-	s{tsr}	scan the file {tsr}.  Several "s" flags can be given, patterns
-		are valid too.
-	i	scan current and included files
-	d	scan current and included files for defined name or macro
-		|i_CTRL-X_CTRL-D|
-	]	tag completion
-	t	same as "]"
-
-	Unloaded buffers are not loaded, thus their autocmds |:autocmd| are
-	not executed, this may lead to unexpected completions from some files
-	(gzipped files for example).  Unloaded buffers are not scanned for
-	whole-line completion.
-
-	The default is ".,w,b,u,t,i", which means to scan:
-	   1. the current buffer
-	   2. buffers in other windows
-	   3. other loaded buffers
-	   4. unloaded buffers
-	   5. tags
-	   6. included files
-
-	As you can see, CTRL-N and CTRL-P can be used to do any 'iskeyword'-
-	based expansion (e.g., dictionary |i_CTRL-X_CTRL-K|, included patterns
-	|i_CTRL-X_CTRL-I|, tags |i_CTRL-X_CTRL-]| and normal expansions).
-
-						*'completefunc'* *'cfu'*
-'completefunc' 'cfu'	string	(default: empty)
-			local to buffer
-			{not available when compiled without the |+eval|
-			feature}
-	This option specifies a function to be used for Insert mode completion
-	with CTRL-X CTRL-U. |i_CTRL-X_CTRL-U|
-	See |complete-functions| for an explanation of how the function is
-	invoked and what it should return.  The value can be the name of a
-	function, a |lambda| or a |Funcref|. See |option-value-function| for
-	more information.
-	This option cannot be set from a |modeline| or in the |sandbox|, for
-	security reasons.
-
-						*'completeslash'* *'csl'*
-'completeslash' 'csl'	string	(default: "")
-			local to buffer
-			{only for MS-Windows}
-	When this option is set it overrules 'shellslash' for completion:
-	- When this option is set to "slash", a forward slash is used for path
-	  completion in insert mode. This is useful when editing HTML tag, or
-	  Makefile with 'noshellslash' on MS-Windows.
-	- When this option is set to "backslash", backslash is used. This is
-	  useful when editing a batch file with 'shellslash' set on MS-Windows.
-	- When this option is empty, same character is used as for
-	  'shellslash'.
-	For Insert mode completion the buffer-local value is used.  For
-	command line completion the global value is used.
-
-						*'completeopt'* *'cot'*
-'completeopt' 'cot'	string	(default: "menu,preview")
-			global
-	A comma-separated list of options for Insert mode completion
-	|ins-completion|.  The supported values are:
-
-	   menu	    Use a popup menu to show the possible completions.  The
-		    menu is only shown when there is more than one match and
-		    sufficient colors are available.  |ins-completion-menu|
-
-	   menuone  Use the popup menu also when there is only one match.
-		    Useful when there is additional information about the
-		    match, e.g., what file it comes from.
-
-	   longest  Only insert the longest common text of the matches.  If
-		    the menu is displayed you can use CTRL-L to add more
-		    characters.  Whether case is ignored depends on the kind
-		    of completion.  For buffer text the 'ignorecase' option is
-		    used.
-
-	   preview  Show extra information about the currently selected
-		    completion in the preview window.  Only works in
-		    combination with "menu" or "menuone".
-
-	   popup    Show extra information about the currently selected
-		    completion in a popup window.  Only works in combination
-		    with "menu" or "menuone".  Overrides "preview".
-		    See |'completepopup'| for specifying properties.
-		    {only works when compiled with the |+textprop| feature}
-
-	   popuphidden
-		    Just like "popup" but initially hide the popup.  Use a
-		    |CompleteChanged| autocommand to fetch the info and call
-		    |popup_show()| once the popup has been filled.
-		    See the example at |complete-popuphidden|.
-		    {only works when compiled with the |+textprop| feature}
-
-	   noinsert Do not insert any text for a match until the user selects
-		    a match from the menu. Only works in combination with
-		    "menu" or "menuone". No effect if "longest" is present.
-
-	   noselect Do not select a match in the menu, force the user to
-		    select one from the menu. Only works in combination with
-		    "menu" or "menuone".
-
-
-					*'completepopup'* *'cpp'*
-'completepopup' 'cpp'	string (default empty)
-			global
-			{not available when compiled without the |+textprop|
-			or |+quickfix| feature}
-	When 'completeopt' contains "popup" then this option is used for the
-	properties of the info popup when it is created.  If an info popup
-	window already exists it is closed, so that the option value is
-	applied when it is created again.
-	You can also use |popup_findinfo()| and then set properties for an
-	existing info popup with |popup_setoptions()|.  See |complete-popup|.
-
-
-						*'concealcursor'* *'cocu'*
-'concealcursor' 'cocu'	string (default: "")
-			local to window
-			{not available when compiled without the |+conceal|
-			feature}
-	Sets the modes in which text in the cursor line can also be concealed.
-	When the current mode is listed then concealing happens just like in
-	other lines.
-	  n		Normal mode
-	  v		Visual mode
-	  i		Insert mode
-	  c		Command line editing, for 'incsearch'
-
-	'v' applies to all lines in the Visual area, not only the cursor.
-	A useful value is "nc".  This is used in help files.  So long as you
-	are moving around text is concealed, but when starting to insert text
-	or selecting a Visual area the concealed text is displayed, so that
-	you can see what you are doing.
-	Keep in mind that the cursor position is not always where it's
-	displayed.  E.g., when moving vertically it may change column.
-
-
-						*'conceallevel'* *'cole'*
-'conceallevel' 'cole'	number (default 0)
-			local to window
-			{not available when compiled without the |+conceal|
-			feature}
-	Determine how text with the "conceal" syntax attribute |:syn-conceal|
-	is shown:
-
-	Value		Effect ~
-	0		Text is shown normally
-	1		Each block of concealed text is replaced with one
-			character.  If the syntax item does not have a custom
-			replacement character defined (see |:syn-cchar|) the
-			character defined in 'listchars' is used (default is a
-			space).
-			It is highlighted with the "Conceal" highlight group.
-	2		Concealed text is completely hidden unless it has a
-			custom replacement character defined (see
-			|:syn-cchar|).
-	3		Concealed text is completely hidden.
-
-	Note: in the cursor line concealed text is not hidden, so that you can
-	edit and copy the text.  This can be changed with the 'concealcursor'
-	option.
-
-				*'confirm'* *'cf'* *'noconfirm'* *'nocf'*
-'confirm' 'cf'		boolean (default off)
-			global
-	When 'confirm' is on, certain operations that would normally
-	fail because of unsaved changes to a buffer, e.g. ":q" and ":e",
-	instead raise a |dialog| asking if you wish to save the current
-	file(s).  You can still use a ! to unconditionally |abandon| a buffer.
-	If 'confirm' is off you can still activate confirmation for one
-	command only (this is most useful in mappings) with the |:confirm|
-	command.
-	Also see the |confirm()| function and the 'v' flag in 'guioptions'.
-
-			*'conskey'* *'consk'* *'noconskey'* *'noconsk'*
-'conskey' 'consk'	boolean	(default off)
-			global
-	This was for MS-DOS and is no longer supported.
-
-			*'copyindent'* *'ci'* *'nocopyindent'* *'noci'*
-'copyindent' 'ci'	boolean	(default off)
-			local to buffer
-	Copy the structure of the existing lines indent when autoindenting a
-	new line.  Normally the new indent is reconstructed by a series of
-	tabs followed by spaces as required (unless |'expandtab'| is enabled,
-	in which case only spaces are used).  Enabling this option makes the
-	new line copy whatever characters were used for indenting on the
-	existing line.  'expandtab' has no effect on these characters, a Tab
-	remains a Tab.  If the new indent is greater than on the existing
-	line, the remaining space is filled in the normal manner.
-	NOTE: This option is reset when 'compatible' is set.
-	Also see 'preserveindent'.
-
-						*'cpoptions'* *'cpo'* *cpo*
-'cpoptions' 'cpo'	string	(Vim default: "aABceFs",
-				 Vi default:  all flags)
-			global
-	A sequence of single character flags.  When a character is present
-	this indicates Vi-compatible behavior.  This is used for things where
-	not being Vi-compatible is mostly or sometimes preferred.
-	'cpoptions' stands for "compatible-options".
-	Commas can be added for readability.
-	To avoid problems with flags that are added in the future, use the
-	"+=" and "-=" feature of ":set" |add-option-flags|.
-
-	NOTE: This option is set to the Vi default value when 'compatible' is
-	set and to the Vim default value when 'compatible' is reset.
-
-	NOTE: In a |Vim9| script, when `vim9script` is encountered, the value
-	is saved, 'cpoptions' is set to the Vim default, and the saved value
-	is restored at the end of the script.  Changes to the value of
-	'cpoptions' will be applied to the saved value, but keep in mind that
-	removing a flag that is not present when 'cpoptions' is changed has no
-	effect.  In the |.vimrc| file the value is not restored, thus using
-	`vim9script` in the |.vimrc| file results in using the Vim default.
-
-	NOTE: This option is set to the POSIX default value at startup when
-	the Vi default value would be used and the $VIM_POSIX environment
-	variable exists |posix|.  This means Vim tries to behave like the
-	POSIX specification.
-
-	    contains	behavior	~
-								*cpo-a*
-		a	When included, a ":read" command with a file name
-			argument will set the alternate file name for the
-			current window.
-								*cpo-A*
-		A	When included, a ":write" command with a file name
-			argument will set the alternate file name for the
-			current window.
-								*cpo-b*
-		b	"\|" in a ":map" command is recognized as the end of
-			the map command.  The '\' is included in the mapping,
-			the text after the '|' is interpreted as the next
-			command.  Use a CTRL-V instead of a backslash to
-			include the '|' in the mapping.  Applies to all
-			mapping, abbreviation, menu and autocmd commands.
-			See also |map_bar|.
-								*cpo-B*
-		B	A backslash has no special meaning in mappings,
-			abbreviations, user commands and the "to" part of the
-			menu commands.  Remove this flag to be able to use a
-			backslash like a CTRL-V.  For example, the command
-			":map X \<Esc>" results in X being mapped to:
-				'B' included:	"\^["	 (^[ is a real <Esc>)
-				'B' excluded:	"<Esc>"  (5 characters)
-				('<' excluded in both cases)
-								*cpo-c*
-		c	Searching continues at the end of any match at the
-			cursor position, but not further than the start of the
-			next line.  When not present searching continues
-			one character from the cursor position.  With 'c'
-			"abababababab" only gets three matches when repeating
-			"/abab", without 'c' there are five matches.
-								*cpo-C*
-		C	Do not concatenate sourced lines that start with a
-			backslash.  See |line-continuation|.
-								*cpo-d*
-		d	Using "./" in the 'tags' option doesn't mean to use
-			the tags file relative to the current file, but the
-			tags file in the current directory.
-								*cpo-D*
-		D	Can't use CTRL-K to enter a digraph after Normal mode
-			commands with a character argument, like |r|, |f| and
-			|t|.
-								*cpo-e*
-		e	When executing a register with ":@r", always add a
-			<CR> to the last line, also when the register is not
-			linewise.  If this flag is not present, the register
-			is not linewise and the last line does not end in a
-			<CR>, then the last line is put on the command-line
-			and can be edited before hitting <CR>.
-								*cpo-E*
-		E	It is an error when using "y", "d", "c", "g~", "gu" or
-			"gU" on an Empty region.  The operators only work when
-			at least one character is to be operated on.  Example:
-			This makes "y0" fail in the first column.
-								*cpo-f*
-		f	When included, a ":read" command with a file name
-			argument will set the file name for the current buffer,
-			if the current buffer doesn't have a file name yet.
-								*cpo-F*
-		F	When included, a ":write" command with a file name
-			argument will set the file name for the current
-			buffer, if the current buffer doesn't have a file name
-			yet.  Also see |cpo-P|.
-								*cpo-g*
-		g	Goto line 1 when using ":edit" without argument.
-								*cpo-H*
-		H	When using "I" on a line with only blanks, insert
-			before the last blank.  Without this flag insert after
-			the last blank.
-								*cpo-i*
-		i	When included, interrupting the reading of a file will
-			leave it modified.
-								*cpo-I*
-		I	When moving the cursor up or down just after inserting
-			indent for 'autoindent', do not delete the indent.
-								*cpo-j*
-		j	When joining lines, only add two spaces after a '.',
-			not after '!' or '?'.  Also see 'joinspaces'.
-								*cpo-J*
-		J	A |sentence| has to be followed by two spaces after
-			the '.', '!' or '?'.  A <Tab> is not recognized as
-			white space.
-								*cpo-k*
-		k	Disable the recognition of raw key codes in
-			mappings, abbreviations, and the "to" part of menu
-			commands.  For example, if <Key> sends ^[OA (where ^[
-			is <Esc>), the command ":map X ^[OA" results in X
-			being mapped to:
-				'k' included:	"^[OA"	 (3 characters)
-				'k' excluded:	"<Key>"  (one key code)
-			Also see the '<' flag below.
-								*cpo-K*
-		K	Don't wait for a key code to complete when it is
-			halfway a mapping.  This breaks mapping <F1><F1> when
-			only part of the second <F1> has been read.  It
-			enables cancelling the mapping by typing <F1><Esc>.
-								*cpo-l*
-		l	Backslash in a [] range in a search pattern is taken
-			literally, only "\]", "\^", "\-" and "\\" are special.
-			See |/[]|
-			   'l' included: "/[ \t]"  finds <Space>, '\' and 't'
-			   'l' excluded: "/[ \t]"  finds <Space> and <Tab>
-			Also see |cpo-\|.
-								*cpo-L*
-		L	When the 'list' option is set, 'wrapmargin',
-			'textwidth', 'softtabstop' and Virtual Replace mode
-			(see |gR|) count a <Tab> as two characters, instead of
-			the normal behavior of a <Tab>.
-								*cpo-m*
-		m	When included, a showmatch will always wait half a
-			second.  When not included, a showmatch will wait half
-			a second or until a character is typed.  |'showmatch'|
-								*cpo-M*
-		M	When excluded, "%" matching will take backslashes into
-			account.  Thus in "( \( )" and "\( ( \)" the outer
-			parenthesis match.  When included "%" ignores
-			backslashes, which is Vi compatible.
-								*cpo-n*
-		n	When included, the column used for 'number' and
-			'relativenumber' will also be used for text of wrapped
-			lines.
-								*cpo-o*
-		o	Line offset to search command is not remembered for
-			next search.
-								*cpo-O*
-		O	Don't complain if a file is being overwritten, even
-			when it didn't exist when editing it.  This is a
-			protection against a file unexpectedly created by
-			someone else.  Vi didn't complain about this.
-								*cpo-p*
-		p	Vi compatible Lisp indenting.  When not present, a
-			slightly better algorithm is used.
-								*cpo-P*
-		P	When included, a ":write" command that appends to a
-			file will set the file name for the current buffer, if
-			the current buffer doesn't have a file name yet and
-			the 'F' flag is also included |cpo-F|.
-								*cpo-q*
-		q	When joining multiple lines leave the cursor at the
-			position where it would be when joining two lines.
-								*cpo-r*
-		r	Redo ("." command) uses "/" to repeat a search
-			command, instead of the actually used search string.
-								*cpo-R*
-		R	Remove marks from filtered lines.  Without this flag
-			marks are kept like |:keepmarks| was used.
-								*cpo-s*
-		s	Set buffer options when entering the buffer for the
-			first time.  This is like it is in Vim version 3.0.
-			And it is the default.  If not present the options are
-			set when the buffer is created.
-								*cpo-S*
-		S	Set buffer options always when entering a buffer
-			(except 'readonly', 'fileformat', 'filetype' and
-			'syntax').  This is the (most) Vi compatible setting.
-			The options are set to the values in the current
-			buffer.  When you change an option and go to another
-			buffer, the value is copied.  Effectively makes the
-			buffer options global to all buffers.
-
-			's'    'S'     copy buffer options
-			no     no      when buffer created
-			yes    no      when buffer first entered (default)
-			 X     yes     each time when buffer entered (vi comp.)
-								*cpo-t*
-		t	Search pattern for the tag command is remembered for
-			"n" command.  Otherwise Vim only puts the pattern in
-			the history for search pattern, but doesn't change the
-			last used search pattern.
-								*cpo-u*
-		u	Undo is Vi compatible.  See |undo-two-ways|.
-								*cpo-v*
-		v	Backspaced characters remain visible on the screen in
-			Insert mode.  Without this flag the characters are
-			erased from the screen right away.  With this flag the
-			screen newly typed text overwrites backspaced
-			characters.
-								*cpo-w*
-		w	When using "cw" on a blank character, only change one
-			character and not all blanks until the start of the
-			next word.
-								*cpo-W*
-		W	Don't overwrite a readonly file.  When omitted, ":w!"
-			overwrites a readonly file, if possible.
-								*cpo-x*
-		x	<Esc> on the command-line executes the command-line.
-			The default in Vim is to abandon the command-line,
-			because <Esc> normally aborts a command.  |c_<Esc>|
-								*cpo-X*
-		X	When using a count with "R" the replaced text is
-			deleted only once.  Also when repeating "R" with "."
-			and a count.
-								*cpo-y*
-		y	A yank command can be redone with ".".  Think twice if
-			you really want to use this, it may break some
-			plugins, since most people expect "." to only repeat a
-			change.
-								*cpo-Z*
-		Z	When using "w!" while the 'readonly' option is set,
-			don't reset 'readonly'.
-								*cpo-!*
-		!	When redoing a filter command, use the last used
-			external command, whatever it was.  Otherwise the last
-			used -filter- command is used.
-								*cpo-$*
-		$	When making a change to one line, don't redisplay the
-			line, but put a '$' at the end of the changed text.
-			The changed text will be overwritten when you type the
-			new text.  The line is redisplayed if you type any
-			command that moves the cursor from the insertion
-			point.
-								*cpo-%*
-		%	Vi-compatible matching is done for the "%" command.
-			Does not recognize "#if", "#endif", etc.
-			Does not recognize "/*" and "*/".
-			Parens inside single and double quotes are also
-			counted, causing a string that contains a paren to
-			disturb the matching.  For example, in a line like
-			"if (strcmp("foo(", s))" the first paren does not
-			match the last one.  When this flag is not included,
-			parens inside single and double quotes are treated
-			specially.  When matching a paren outside of quotes,
-			everything inside quotes is ignored.  When matching a
-			paren inside quotes, it will find the matching one (if
-			there is one).  This works very well for C programs.
-			This flag is also used for other features, such as
-			C-indenting.
-								*cpo--*
-		-	When included, a vertical movement command fails when
-			it would go above the first line or below the last
-			line.  Without it the cursor moves to the first or
-			last line, unless it already was in that line.
-			Applies to the commands "-", "k", CTRL-P, "+", "j",
-			CTRL-N, CTRL-J and ":1234".
-								*cpo-+*
-		+	When included, a ":write file" command will reset the
-			'modified' flag of the buffer, even though the buffer
-			itself may still be different from its file.
-								*cpo-star*
-		*	Use ":*" in the same way as ":@".  When not included,
-			":*" is an alias for ":'<,'>", select the Visual area.
-								*cpo-<*
-		<	Disable the recognition of special key codes in |<>|
-			form in mappings, abbreviations, and the "to" part of
-			menu commands.  For example, the command
-			":map X <Tab>" results in X being mapped to:
-				'<' included:	"<Tab>"  (5 characters)
-				'<' excluded:	"^I"	 (^I is a real <Tab>)
-			Also see the 'k' flag above.
-								*cpo->*
-		>	When appending to a register, put a line break before
-			the appended text.
-								*cpo-;*
-		;	When using |,| or |;| to repeat the last |t| search
-			and the cursor is right in front of the searched
-			character, the cursor won't move. When not included,
-			the cursor would skip over it and jump to the
-			following occurrence.
-
-	POSIX flags.  These are not included in the Vi default value, except
-	when $VIM_POSIX was set on startup. |posix|
-
-	    contains	behavior	~
-								*cpo-#*
-		#	A count before "D", "o" and "O" has no effect.
-								*cpo-&*
-		&	When ":preserve" was used keep the swap file when
-			exiting normally while this buffer is still loaded.
-			This flag is tested when exiting.
-								*cpo-\*
-		\	Backslash in a [] range in a search pattern is taken
-			literally, only "\]" is special  See |/[]|
-			   '\' included: "/[ \-]"  finds <Space>, '\' and '-'
-			   '\' excluded: "/[ \-]"  finds <Space> and '-'
-			Also see |cpo-l|.
-								*cpo-/*
-		/	When "%" is used as the replacement string in a |:s|
-			command, use the previous replacement string. |:s%|
-								*cpo-{*
-		{	The |{| and |}| commands also stop at a "{" character
-			at the start of a line.
-								*cpo-.*
-		.	The ":chdir" and ":cd" commands fail if the current
-			buffer is modified, unless ! is used.  Vim doesn't
-			need this, since it remembers the full path of an
-			opened file.
-								*cpo-bar*
-		|	The value of the $LINES and $COLUMNS environment
-			variables overrule the terminal size values obtained
-			with system specific functions.
-
-
-						*'cryptmethod'* *'cm'*
-'cryptmethod' 'cm'	string	(default "blowfish2")
-			global or local to buffer |global-local|
-	Method used for encryption when the buffer is written to a file:
-							*pkzip*
-	   zip		PkZip compatible method.  A weak kind of encryption.
-			Backwards compatible with Vim 7.2 and older.
-			Only use if you need to be backwards compatible.
-							*blowfish*
-	   blowfish	Blowfish method.  Medium strong encryption but it has
-			an implementation flaw.  Requires Vim 7.3 or later,
-			files can NOT be read by Vim 7.2 and older.  This adds
-			a "seed" to the file, every time you write the file
-			the encrypted bytes will be different.
-			Obsolete, please do no longer use.
-							*blowfish2*
-	   blowfish2	Blowfish method.  Medium strong encryption.  Requires
-			Vim 7.4.401 or later, files can NOT be read by Vim 7.3
-			and older.  This adds a "seed" to the file, every time
-			you write the file the encrypted bytes will be
-			different.  The whole undo file is encrypted, not just
-			the pieces of text.
-					*E1193* *E1194* *E1195* *E1196* *E1230*
-					*E1197* *E1198* *E1199* *E1200* *E1201*
-	   xchacha20	XChaCha20 Cipher with Poly1305 Message Authentication
-			Code.  Medium strong till strong encryption.
-			Encryption is provided by the libsodium library, it
-			requires Vim to be built with |+sodium|.
-			It adds a seed and a message authentication code (MAC)
-			to the file.  This needs at least a Vim 8.2.3022 to
-			read the encrypted file.
-			Encryption of swap files is not supported, therefore
-			no swap file will be used when xchacha20 encryption is
-			enabled.
-			Encryption of undo files is not yet supported,
-			therefore no undo file will currently be written.
-			CAREFUL: Files written with this method might have to
-			be read back with the same version of Vim if the
-			binary format changes later.
-			Obsolete, please do no longer use.
-	   xchacha20v2  Same algorithm as with "xchacha20" that correctly
-			stores the key derivation parameters together with the
-			encrypted file.  Should work better in case the
-			parameters in the libsodium library ever change.
-			STILL EXPERIMENTAL: Files written with this method
-			might have to be read back with the same version of
-			Vim if the binary format changes later.
-
-	You should use "blowfish2", also to re-encrypt older files.  The
-	"xchacha20" method provides better encryption, but it does not work
-	with all versions of Vim.
-
-	When reading an encrypted file 'cryptmethod' will be set automatically
-	to the detected method of the file being read.  Thus if you write it
-	without changing 'cryptmethod' the same method will be used.
-	Changing 'cryptmethod' does not mark the file as modified, you have to
-	explicitly write it, you don't get a warning unless there are other
-	modifications.  Also see |:X|.
-
-	When setting the global value to an empty string, it will end up with
-	the value "blowfish2".  When setting the local value to an empty
-	string the buffer will use the global value.
-
-	When a new encryption method is added in a later version of Vim, and
-	the current version does not recognize it, you will get	*E821* .
-	You need to edit this file with the later version of Vim.

-						*'cscopepathcomp'* *'cspc'*
-'cscopepathcomp' 'cspc'	number	(default 0)
-			global
-			{not available when compiled without the |+cscope|

-	Specifies the command to execute cscope.  See |cscopeprg|.
-	This option cannot be set from a |modeline| or in the |sandbox|, for
-	security reasons.
-
-						*'cscopequickfix'* *'csqf'*
-'cscopequickfix' 'csqf' string	(default "")
-			global

-	Specifies whether to use quickfix window to show cscope results.
-	See |cscopequickfix|.
-
-		*'cscoperelative'* *'csre'* *'nocscoperelative'* *'nocsre'*
-'cscoperelative' 'csre' boolean (default off)
-			global
-			{not available when compiled without the |+cscope|
-			feature}
-	In the absence of a prefix (-P) for cscope. setting this option enables
-	to use the basename of cscope.out path as the prefix.
-	See |cscoperelative|.
-	NOTE: This option is reset when 'compatible' is set.
-
-				*'cscopetag'* *'cst'* *'nocscopetag'* *'nocst'*
-'cscopetag' 'cst'	boolean (default off)
-			global
-			{not available when compiled without the |+cscope|
-			feature}
-	Use cscope for tag commands.  See |cscope-options|.
-	NOTE: This option is reset when 'compatible' is set.
-

-'cscopetagorder' 'csto'	number	(default 0)
-			global
-			{not available when compiled without the |+cscope|
-			feature}
-	Determines the order in which ":cstag" performs a search.  See

-					*'nocscopeverbose'* *'nocsverb'*
-'cscopeverbose' 'csverb' boolean (default off)
-			global
-			{not available when compiled without the |+cscope|
-			feature}
-	Give messages when adding a cscope database.  See |cscopeverbose|.
-	NOTE: This option is reset when 'compatible' is set.
-
-			*'cursorbind'* *'crb'* *'nocursorbind'* *'nocrb'*
-'cursorbind' 'crb'	boolean  (default off)
-			local to window
-	When this option is set, as the cursor in the current
-	window moves other cursorbound windows (windows that also have
-	this option set) move their cursors to the corresponding line and
-	column.  This option is useful for viewing the
-	differences between two versions of a file (see 'diff'); in diff mode,
-	inserted and deleted lines (though not characters within a line) are
-	taken into account.
-
-
-			*'cursorcolumn'* *'cuc'* *'nocursorcolumn'* *'nocuc'*
-'cursorcolumn' 'cuc'	boolean	(default off)
-			local to window
-			{not available when compiled without the |+syntax|
-			feature}
-	Highlight the screen column of the cursor with CursorColumn
-	|hl-CursorColumn|.  Useful to align text.  Will make screen redrawing
-	slower.
-	If you only want the highlighting in the current window you can use
-	these autocommands: >
-		au WinLeave * set nocursorline nocursorcolumn
-		au WinEnter * set cursorline cursorcolumn
-<
-
-			*'cursorline'* *'cul'* *'nocursorline'* *'nocul'*
-'cursorline' 'cul'	boolean	(default off)
-			local to window
-			{not available when compiled without the |+syntax|
-			feature}
-	Highlight the text line of the cursor with CursorLine |hl-CursorLine|.
-	Useful to easily spot the cursor.  Will make screen redrawing slower.
-	When Visual mode is active the highlighting isn't used to make it
-	easier to see the selected text.
-
-
-						*'cursorlineopt'* *'culopt'*
-'cursorlineopt' 'culopt' string (default: "number,line")
-			local to window
-			{not available when compiled without the |+syntax|
-			feature}
-	Comma-separated list of settings for how 'cursorline' is displayed.
-	Valid values:
-	"line"		Highlight the text line of the cursor with
-			CursorLine |hl-CursorLine|.
-	"screenline"	Highlight only the screen line of the cursor with
-			CursorLine |hl-CursorLine|.
-	"number"	Highlight the line number of the cursor with
-			CursorLineNr |hl-CursorLineNr|.
-
-	Special value:
-	"both"		Alias for the values "line,number".
-
-	"line" and "screenline" cannot be used together.
-
-
-						*'debug'*
-'debug'			string	(default "")
-			global
-	These values can be used:
-	msg	Error messages that would otherwise be omitted will be given
-		anyway.
-	throw	Error messages that would otherwise be omitted will be given
-		anyway and also throw an exception and set |v:errmsg|.
-	beep	A message will be given when otherwise only a beep would be
-		produced.
-	The values can be combined, separated by a comma.
-	"msg" and "throw" are useful for debugging 'foldexpr', 'formatexpr' or
-	'indentexpr'.
-
-						*'define'* *'def'*
-'define' 'def'		string	(default "^\s*#\s*define")
-			global or local to buffer |global-local|
-	Pattern to be used to find a macro definition.  It is a search
-	pattern, just like for the "/" command.  This option is used for the
-	commands like "[i" and "[d" |include-search|.  The 'isident' option is
-	used to recognize the defined name after the match:
-		{match with 'define'}{non-ID chars}{defined name}{non-ID char}
-	See |option-backslash| about inserting backslashes to include a space
-	or backslash.
-	The default value is for C programs.  For C++ this value would be
-	useful, to include const type declarations: >
-		^\(#\s*define\|[a-z]*\s*const\s*[a-z]*\)
-<	You can also use "\ze" just before the name and continue the pattern
-	to check what is following.  E.g. for Javascript, if a function is
-	defined with "func_name = function(args)": >
-		^\s*\ze\i\+\s*=\s*function(
-<	If the function is defined with "func_name : function() {...": >
-	        ^\s*\ze\i\+\s*[:]\s*(*function\s*(
-<	When using the ":set" command, you need to double the backslashes!
-	To avoid that use `:let` with a single quote string: >
-		let &l:define = '^\s*\ze\k\+\s*=\s*function('
-<
-
-			*'delcombine'* *'deco'* *'nodelcombine'* *'nodeco'*
-'delcombine' 'deco'	boolean (default off)
-			global
-	If editing Unicode and this option is set, backspace and Normal mode
-	"x" delete each combining character on its own.  When it is off (the
-	default) the character along with its combining characters are
-	deleted.
-	Note: When 'delcombine' is set "xx" may work differently from "2x"!
-
-	This is useful for Arabic, Hebrew and many other languages where one
-	may have combining characters overtop of base characters, and want
-	to remove only the combining ones.
-	NOTE: This option is reset when 'compatible' is set.
-
-						*'dictionary'* *'dict'*
-'dictionary' 'dict'	string	(default "")
-			global or local to buffer |global-local|
-	List of file names, separated by commas, that are used to lookup words
-	for keyword completion commands |i_CTRL-X_CTRL-K|.  Each file should
-	contain a list of words.  This can be one word per line, or several
-	words per line, separated by non-keyword characters (white space is
-	preferred).  Maximum line length is 510 bytes.
-
-	When this option is empty or an entry "spell" is present, and spell
-	checking is enabled, words in the word lists for the currently active
-	'spelllang' are used. See |spell|.
-
-	To include a comma in a file name precede it with a backslash.  Spaces
-	after a comma are ignored, otherwise spaces are included in the file
-	name.  See |option-backslash| about using backslashes.
-	This has nothing to do with the |Dictionary| variable type.
-	Where to find a list of words?
-	- On FreeBSD, there is the file "/usr/share/dict/words".
-	- In the Simtel archive, look in the "msdos/linguist" directory.
-	- In "miscfiles" of the GNU collection.
-	The use of |:set+=| and |:set-=| is preferred when adding or removing

-	uses another default.
-	Backticks cannot be used in this option for security reasons.
-
-							*'diff'* *'nodiff'*
-'diff'			boolean	(default off)
-			local to window
-			{not available when compiled without the |+diff|
-			feature}
-	Join the current window in the group of windows that shows differences
-	between files.  See |vimdiff|.
-
-						*'dex'* *'diffexpr'*
-'diffexpr' 'dex'	string	(default "")
-			global
-			{not available when compiled without the |+diff|
-			feature}
-	Expression which is evaluated to obtain a diff file (either ed-style
-	or unified-style) from two versions of a file.  See |diff-diffexpr|.
-	This option cannot be set from a |modeline| or in the |sandbox|, for
-	security reasons.
-
-						*'dip'* *'diffopt'*
-'diffopt' 'dip'		string	(default "internal,filler,closeoff")
-			global
-			{not available when compiled without the |+diff|
-			feature}
-	Option settings for diff mode.  It can consist of the following items.
-	All are optional.  Items must be separated by a comma.
-
-		filler		Show filler lines, to keep the text
-				synchronized with a window that has inserted
-				lines at the same position.  Mostly useful
-				when windows are side-by-side and 'scrollbind'
-				is set.
-
-		context:{n}	Use a context of {n} lines between a change
-				and a fold that contains unchanged lines.
-				When omitted a context of six lines is used.
-				When using zero the context is actually one,
-				since folds require a line in between, also
-				for a deleted line.
-				See |fold-diff|.
-
-		iblank		Ignore changes where lines are all blank.  Adds
-				the "-B" flag to the "diff" command if
-				'diffexpr' is empty.  Check the documentation
-				of the "diff" command for what this does
-				exactly.
-				NOTE: the diff windows will get out of sync,
-				because no differences between blank lines are
-				taken into account.
-
-		icase		Ignore changes in case of text.  "a" and "A"
-				are considered the same.  Adds the "-i" flag
-				to the "diff" command if 'diffexpr' is empty.
-
-		iwhite		Ignore changes in amount of white space.  Adds
-				the "-b" flag to the "diff" command if
-				'diffexpr' is empty.  Check the documentation
-				of the "diff" command for what this does
-				exactly.  It should ignore adding trailing
-				white space, but not leading white space.
-
-		iwhiteall	Ignore all white space changes.  Adds
-				the "-w" flag to the "diff" command if
-				'diffexpr' is empty.  Check the documentation
-				of the "diff" command for what this does
-				exactly.
-
-		iwhiteeol	Ignore white space changes at end of line.
-				Adds the "-Z" flag to the "diff" command if
-				'diffexpr' is empty.  Check the documentation
-				of the "diff" command for what this does
-				exactly.
-
-		horizontal	Start diff mode with horizontal splits (unless
-				explicitly specified otherwise).
-
-		vertical	Start diff mode with vertical splits (unless
-				explicitly specified otherwise).
-
-		closeoff	When a window is closed where 'diff' is set
-				and there is only one window remaining in the
-				same tab page with 'diff' set, execute
-				`:diffoff` in that window.  This undoes a
-				`:diffsplit` command.
-
-		hiddenoff	Do not use diff mode for a buffer when it
-				becomes hidden.
-
-		foldcolumn:{n}	Set the 'foldcolumn' option to {n} when
-				starting diff mode.  Without this 2 is used.
-
-		followwrap	Follow the 'wrap' option and leave as it is.
-
-		internal	Use the internal diff library.  This is
-				ignored when 'diffexpr' is set.  *E960*
-				When running out of memory when writing a
-				buffer this item will be ignored for diffs
-				involving that buffer.  Set the 'verbose'
-				option to see when this happens.
-
-		indent-heuristic
-				Use the indent heuristic for the internal
-				diff library.
-
-                algorithm:{text} Use the specified diff algorithm with the
-				internal diff engine. Currently supported
-				algorithms are:
-				myers      the default algorithm
-				minimal    spend extra time to generate the
-					   smallest possible diff
-				patience   patience diff algorithm
-				histogram  histogram diff algorithm
-
-	Examples: >
-		:set diffopt=internal,filler,context:4
-		:set diffopt=
-		:set diffopt=internal,filler,foldcolumn:3
-		:set diffopt-=internal  " do NOT use the internal diff parser
-<
-				     *'digraph'* *'dg'* *'nodigraph'* *'nodg'*
-'digraph' 'dg'		boolean	(default off)
-			global
-			{not available when compiled without the |+digraphs|
-			feature}
-	Enable the entering of digraphs in Insert mode with {char1} <BS>
-	{char2}.  See |digraphs|.
-	NOTE: This option is reset when 'compatible' is set.
-
-						*'directory'* *'dir'*
-'directory' 'dir'	string	(default for Amiga: ".,t:",
-				 for Win32: ".,$TEMP,c:\tmp,c:\temp"
-				 for Unix: ".,~/tmp,/var/tmp,/tmp")
-			global
-	List of directory names for the swap file, separated with commas.
-	Recommended value:  ".,~/vimswap//" - this will put the swap file next
-	to the edited file if possible, and in your personal swap directory
-	otherwise.  Make sure "~/vimswap//" is only readable for you.
-
-	Possible items:
-	- The swap file will be created in the first directory where this is
-	  possible.
-	- Empty means that no swap file will be used (recovery is
-	  impossible!) and no |E303| error will be given.
-	- A directory "." means to put the swap file in the same directory as
-	  the edited file.  On Unix, a dot is prepended to the file name, so
-	  it doesn't show in a directory listing.  On MS-Windows the "hidden"
-	  attribute is set and a dot prepended if possible.
-	- A directory starting with "./" (or ".\" for MS-Windows) means to put
-	  the swap file relative to where the edited file is.  The leading "."
-	  is replaced with the path name of the edited file.
-	- For Unix and Win32, if a directory ends in two path separators "//",
-	  the swap file name will be built from the complete path to the file
-	  with all path separators replaced by percent '%' signs (including
-	  the colon following the drive letter on Win32). This will ensure
-	  file name uniqueness in the preserve directory.
-	  On Win32, it is also possible to end with "\\".  However, When a
-	  separating comma is following, you must use "//", since "\\" will
-	  include the comma in the file name. Therefore it is recommended to
-	  use '//', instead of '\\'.
-	- Spaces after the comma are ignored, other spaces are considered part
-	  of the directory name.  To have a space at the start of a directory
-	  name, precede it with a backslash.
-	- To include a comma in a directory name precede it with a backslash.
-	- A directory name may end in an ':' or '/'.
-	- Environment variables are expanded |:set_env|.
-	- Careful with '\' characters, type one before a space, type two to
-	  get one in the option (see |option-backslash|), for example: >
-	    :set dir=c:\\tmp,\ dir\\,with\\,commas,\\\ dir\ with\ spaces
-<	- For backwards compatibility with Vim version 3.0 a '>' at the start
-	  of the option is removed.
-	Using "." first in the list is recommended.  This means that editing
-	the same file twice will result in a warning.  Using "/tmp" on Unix is
-	discouraged: When the system crashes you lose the swap file.
-	"/var/tmp" is often not cleared when rebooting, thus is a better
-	choice than "/tmp".  But others on the computer may be able to see the
-	files, and it can contain a lot of files, your swap files get lost in
-	the crowd.  That is why a "tmp" directory in your home directory is
-	tried first.
-	The use of |:set+=| and |:set-=| is preferred when adding or removing
-	directories from the list.  This avoids problems when a future version
-	uses another default.
-	This option cannot be set from a |modeline| or in the |sandbox|, for
-	security reasons.
-
-					*'display'* *'dy'*
-'display' 'dy'		string	(default "", set to "truncate" in
-							       |defaults.vim|)
-			global
-	Change the way text is displayed.  This is a comma-separated list of
-	flags:
-	lastline	When included, as much as possible of the last line
-			in a window will be displayed.  "@@@" is put in the
-			last columns of the last screen line to indicate the
-			rest of the line is not displayed.
-	truncate	Like "lastline", but "@@@" is displayed in the first
-			column of the last screen line.  Overrules "lastline".
-	uhex		Show unprintable characters hexadecimal as <xx>
-			instead of using ^C and ~C.
-
-	When neither "lastline" nor "truncate" is included, a last line that
-	doesn't fit is replaced with "@" lines.
-
-	The "@" character can be changed by setting the "lastline" item in
-	'fillchars'.  The character is highlighted with |hl-NonText|.
-
-						*'eadirection'* *'ead'*
-'eadirection' 'ead'	string	(default "both")
-			global
-	Tells when the 'equalalways' option applies:
-		ver	vertically, width of windows is not affected
-		hor	horizontally, height of windows is not affected
-		both	width and height of windows is affected
-
-			   *'ed'* *'edcompatible'* *'noed'* *'noedcompatible'*
-'edcompatible' 'ed'	boolean	(default off)
-			global
-	Makes the 'g' and 'c' flags of the ":substitute" command to be
-	toggled each time the flag is given.  See |complex-change|.  See
-	also 'gdefault' option.
-	Switching this option on may break plugins!
-	This option is not used in |Vim9| script.
-
-					*'emoji'* *'emo'* *'noemoji'* *'noemo'*
-'emoji' 'emo'	boolean (default: on)
-			global
-	When on all Unicode emoji characters are considered to be full width.
-	This excludes "text emoji" characters, which are normally displayed as
-	single width.  Unfortunately there is no good specification for this
-	and it has been determined on trial-and-error basis.  Use the
-	|setcellwidths()| function to change the behavior.
-
-					*'encoding'* *'enc'* *E543*
-'encoding' 'enc'	string (default for MS-Windows: "utf-8",
-				otherwise: value from $LANG or "latin1")
-			global
-	Sets the character encoding used inside Vim.  It applies to text in
-	the buffers, registers, Strings in expressions, text stored in the
-	viminfo file, etc.  It sets the kind of characters which Vim can work
-	with.  See |encoding-names| for the possible values.
-
-	NOTE: Changing this option will not change the encoding of the
-	existing text in Vim.  It may cause non-ASCII text to become invalid.
-	It should normally be kept at its default value, or set when Vim
-	starts up.  See |multibyte|.  To reload the menus see |:menutrans|.
-
-	This option cannot be set from a |modeline|.  It would most likely
-	corrupt the text.
-
-	NOTE: For GTK+ 2 or later, it is highly recommended to set 'encoding'
-	to "utf-8".  Although care has been taken to allow different values of
-	'encoding', "utf-8" is the natural choice for the environment and
-	avoids unnecessary conversion overhead.  "utf-8" has not been made
-	the default to prevent different behavior of the GUI and terminal
-	versions, and to avoid changing the encoding of newly created files
-	without your knowledge (in case 'fileencodings' is empty).
-
-	The character encoding of files can be different from 'encoding'.
-	This is specified with 'fileencoding'.  The conversion is done with
-	iconv() or as specified with 'charconvert'.
-
-	If you need to know whether 'encoding' is a multibyte encoding, you
-	can use: >
-		if has("multi_byte_encoding")
-<
-	Normally 'encoding' will be equal to your current locale.  This will
-	be the default if Vim recognizes your environment settings.  If
-	'encoding' is not set to the current locale, 'termencoding' must be
-	set to convert typed and displayed text.  See |encoding-table|.
-
-	When you set this option, it fires the |EncodingChanged| autocommand
-	event so that you can set up fonts if necessary.
-
-	When the option is set, the value is converted to lowercase.  Thus
-	you can set it with uppercase values too.  Underscores are translated
-	to '-' signs.
-	When the encoding is recognized, it is changed to the standard name.
-	For example "Latin-1" becomes "latin1", "ISO_88592" becomes
-	"iso-8859-2" and "utf8" becomes "utf-8".
-
-	Note: "latin1" is also used when the encoding could not be detected.
-	This only works when editing files in the same encoding!  When the
-	actual character set is not latin1, make sure 'fileencoding' and
-	'fileencodings' are empty.  When conversion is needed, switch to using
-	utf-8.
-
-	When "unicode", "ucs-2" or "ucs-4" is used, Vim internally uses utf-8.
-	You don't notice this while editing, but it does matter for the
-	|viminfo-file|.  And Vim expects the terminal to use utf-8 too.  Thus
-	setting 'encoding' to one of these values instead of utf-8 only has
-	effect for encoding used for files when 'fileencoding' is empty.
-
-	When 'encoding' is set to a Unicode encoding, and 'fileencodings' was
-	not set yet, the default for 'fileencodings' is changed.
-
-			*'endoffile'* *'eof'* *'noendoffile'* *'noeof'*
-'endoffile' 'eof'	boolean	(default off)
-			local to buffer
-	Indicates that a CTRL-Z character was found at the end of the file
-	when reading it.  Normally only happens when 'fileformat' is "dos".
-	When writing a file and this option is off and the 'binary' option
-	is on, or 'fixeol' option is off, no CTRL-Z will be written at the
-	end of the file.
-	See |eol-and-eof| for example settings.
-
-			*'endofline'* *'eol'* *'noendofline'* *'noeol'*
-'endofline' 'eol'	boolean	(default on)
-			local to buffer
-	When writing a file and this option is off and the 'binary' option
-	is on, or 'fixeol' option is off, no <EOL> will be written for the
-	last line in the file.  This option is automatically set or reset when
-	starting to edit a new file, depending on whether file has an <EOL>
-	for the last line in the file.  Normally you don't have to set or
-	reset this option.
-	When 'binary' is off and 'fixeol' is on the value is not used when
-	writing the file.  When 'binary' is on or 'fixeol' is off it is used
-	to remember the presence of a <EOL> for the last line in the file, so
-	that when you write the file the situation from the original file can
-	be kept.  But you can change it if you want to.
-	See |eol-and-eof| for example settings.
-
-			     *'equalalways'* *'ea'* *'noequalalways'* *'noea'*
-'equalalways' 'ea'	boolean	(default on)
-			global
-	When on, all the windows are automatically made the same size after
-	splitting or closing a window.  This also happens the moment the
-	option is switched on.  When off, splitting a window will reduce the
-	size of the current window and leave the other windows the same.  When
-	closing a window the extra lines are given to the window next to it
-	(depending on 'splitbelow' and 'splitright').
-	When mixing vertically and horizontally split windows, a minimal size
-	is computed and some windows may be larger if there is room.  The
-	'eadirection' option tells in which direction the size is affected.
-	Changing the height and width of a window can be avoided by setting
-	'winfixheight' and 'winfixwidth', respectively.
-	If a window size is specified when creating a new window sizes are
-	currently not equalized (it's complicated, but may be implemented in
-	the future).
-
-						*'equalprg'* *'ep'*
-'equalprg' 'ep'		string	(default "")
-			global or local to buffer |global-local|
-	External program to use for "=" command.  When this option is empty
-	the internal formatting functions are used; either 'lisp', 'cindent'
-	or 'indentexpr'.  When Vim was compiled without internal formatting,
-	the "indent" program is used.
-	Environment variables are expanded |:set_env|.  See |option-backslash|
-	about including spaces and backslashes.
-	This option cannot be set from a |modeline| or in the |sandbox|, for
-	security reasons.
-
-			*'errorbells'* *'eb'* *'noerrorbells'* *'noeb'*
-'errorbells' 'eb'	boolean	(default off)
-			global
-	Ring the bell (beep or screen flash) for error messages.  This only
-	makes a difference for error messages, the bell will be used always
-	for a lot of errors without a message (e.g., hitting <Esc> in Normal
-	mode).  See 'visualbell' on how to make the bell behave like a beep,
-	screen flash or do nothing. See 'belloff' to finetune when to ring the
-	bell.
-
-						*'errorfile'* *'ef'*
-'errorfile' 'ef'	string	(Amiga default: "AztecC.Err",
-					others: "errors.err")
-			global
-			{not available when compiled without the |+quickfix|
-			feature}
-	Name of the errorfile for the QuickFix mode (see |:cf|).
-	When the "-q" command-line argument is used, 'errorfile' is set to the
-	following argument.  See |-q|.
-	NOT used for the ":make" command.  See 'makeef' for that.
-	Environment variables are expanded |:set_env|.
-	See |option-backslash| about including spaces and backslashes.
-	This option cannot be set from a |modeline| or in the |sandbox|, for
-	security reasons.
-
-						*'errorformat'* *'efm'*
-'errorformat' 'efm'	string	(default is very long)
-			global or local to buffer |global-local|
-			{not available when compiled without the |+quickfix|
-			feature}
-	Scanf-like description of the format for the lines in the error file
-	(see |errorformat|).
-
-				     *'esckeys'* *'ek'* *'noesckeys'* *'noek'*
-'esckeys' 'ek'		boolean	(Vim default: on, Vi default: off)
-			global
-	Function keys that start with an <Esc> are recognized in Insert
-	mode.  When this option is off, the cursor and function keys cannot be
-	used in Insert mode if they start with an <Esc>.  The advantage of
-	this is that the single <Esc> is recognized immediately, instead of
-	after one second.  Instead of resetting this option, you might want to
-	try changing the values for 'timeoutlen' and 'ttimeoutlen'.  Note that
-	when 'esckeys' is off, you can still map anything, but the cursor keys
-	won't work by default.
-	NOTE: This option is set to the Vi default value when 'compatible' is
-	set and to the Vim default value when 'compatible' is reset.
-	NOTE: when this option is off then the |modifyOtherKeys| functionality
-	is disabled while in Insert mode to avoid ending Insert mode with any
-	key that has a modifier.
-
-						*'eventignore'* *'ei'*
-'eventignore' 'ei'	string	(default "")
-			global
-	A list of autocommand event names, which are to be ignored.
-	When set to "all" or when "all" is one of the items, all autocommand
-	events are ignored, autocommands will not be executed.
-	Otherwise this is a comma-separated list of event names.  Example: >
-	    :set ei=WinEnter,WinLeave
-<
-				 *'expandtab'* *'et'* *'noexpandtab'* *'noet'*
-'expandtab' 'et'	boolean	(default off)
-			local to buffer
-	In Insert mode: Use the appropriate number of spaces to insert a
-	<Tab>.  Spaces are used in indents with the '>' and '<' commands and
-	when 'autoindent' is on.  To insert a real tab when 'expandtab' is
-	on, use CTRL-V<Tab>.  See also |:retab| and |ins-expandtab|.
-	This option is reset when the 'paste' option is set and restored when
-	the 'paste' option is reset.
-	NOTE: This option is reset when 'compatible' is set.
-
-					*'exrc'* *'ex'* *'noexrc'* *'noex'*
-'exrc' 'ex'		boolean (default off)
-			global
-	Enables the reading of .vimrc, .exrc and .gvimrc in the current
-	directory.
-
-	Setting this option is a potential security leak.  E.g., consider
-	unpacking a package or fetching files from github, a .vimrc in there
-	might be a trojan horse.  BETTER NOT SET THIS OPTION!
-	Instead, define an autocommand in your .vimrc to set options for a
-	matching directory.
-
-	If you do switch this option on you should also consider setting the
-	'secure' option (see |initialization|).
-	Also see |.vimrc| and |gui-init|.
-	This option cannot be set from a |modeline| or in the |sandbox|, for
-	security reasons.
-
-				*'fileencoding'* *'fenc'* *E213*
-'fileencoding' 'fenc'	string (default: "")
-			local to buffer
-	Sets the character encoding for the file of this buffer.
-
-	When 'fileencoding' is different from 'encoding', conversion will be
-	done when writing the file.  For reading see below.
-	When 'fileencoding' is empty, the same value as 'encoding' will be
-	used (no conversion when reading or writing a file).
-	No error will be given when the value is set, only when it is used,
-	only when writing a file.
-	Conversion will also be done when 'encoding' and 'fileencoding' are
-	both a Unicode encoding and 'fileencoding' is not utf-8.  That's
-	because internally Unicode is always stored as utf-8.
-		WARNING: Conversion can cause loss of information!  When
-		'encoding' is "utf-8" or another Unicode encoding, conversion
-		is most likely done in a way that the reverse conversion
-		results in the same text.  When 'encoding' is not "utf-8" some
-		characters may be lost!
-
-	See 'encoding' for the possible values.  Additionally, values may be
-	specified that can be handled by the converter, see
-	|mbyte-conversion|.
-
-	When reading a file 'fileencoding' will be set from 'fileencodings'.
-	To read a file in a certain encoding it won't work by setting
-	'fileencoding', use the |++enc| argument.  One exception: when
-	'fileencodings' is empty the value of 'fileencoding' is used.
-	For a new file the global value of 'fileencoding' is used.
-
-	Prepending "8bit-" and "2byte-" has no meaning here, they are ignored.
-	When the option is set, the value is converted to lowercase.  Thus
-	you can set it with uppercase values too.  '_' characters are
-	replaced with '-'.  If a name is recognized from the list for
-	'encoding', it is replaced by the standard name.  For example
-	"ISO8859-2" becomes "iso-8859-2".
-
-	When this option is set, after starting to edit a file, the 'modified'
-	option is set, because the file would be different when written.
-
-	Keep in mind that changing 'fenc' from a modeline happens
-	AFTER the text has been read, thus it applies to when the file will be
-	written.  If you do set 'fenc' in a modeline, you might want to set
-	'nomodified' to avoid not being able to ":q".
-
-	This option can not be changed when 'modifiable' is off.
-
-							*'fe'*
-	NOTE: Before version 6.0 this option specified the encoding for the
-	whole of Vim, this was a mistake.  Now use 'encoding' instead.  The
-	old short name was 'fe', which is no longer used.
-
-					*'fileencodings'* *'fencs'*
-'fileencodings' 'fencs'	string (default: "ucs-bom",
-				    "ucs-bom,utf-8,default,latin1" when
-				    'encoding' is set to a Unicode value)
-			global
-	This is a list of character encodings considered when starting to edit
-	an existing file.  When a file is read, Vim tries to use the first
-	mentioned character encoding.  If an error is detected, the next one
-	in the list is tried.  When an encoding is found that works,
-	'fileencoding' is set to it.  If all fail, 'fileencoding' is set to
-	an empty string, which means the value of 'encoding' is used.
-		WARNING: Conversion can cause loss of information!  When
-		'encoding' is "utf-8" (or one of the other Unicode variants)
-		conversion is most likely done in a way that the reverse
-		conversion results in the same text.  When 'encoding' is not
-		"utf-8" some non-ASCII characters may be lost!  You can use
-		the |++bad| argument to specify what is done with characters
-		that can't be converted.
-	For an empty file or a file with only ASCII characters most encodings
-	will work and the first entry of 'fileencodings' will be used (except
-	"ucs-bom", which requires the BOM to be present).  If you prefer
-	another encoding use an BufReadPost autocommand event to test if your
-	preferred encoding is to be used.  Example: >
-		au BufReadPost * if search('\S', 'w') == 0 |
-			\ set fenc=iso-2022-jp | endif
-<	This sets 'fileencoding' to "iso-2022-jp" if the file does not contain
-	non-blank characters.
-	When the |++enc| argument is used then the value of 'fileencodings' is
-	not used.
-	Note that 'fileencodings' is not used for a new file, the global value
-	of 'fileencoding' is used instead.  You can set it with: >
-		:setglobal fenc=iso-8859-2
-<	This means that a non-existing file may get a different encoding than
-	an empty file.
-	The special value "ucs-bom" can be used to check for a Unicode BOM
-	(Byte Order Mark) at the start of the file.  It must not be preceded
-	by "utf-8" or another Unicode encoding for this to work properly.
-	An entry for an 8-bit encoding (e.g., "latin1") should be the last,
-	because Vim cannot detect an error, thus the encoding is always
-	accepted.
-	The special value "default" can be used for the encoding from the
-	environment.  On MS-Windows this is the system encoding.  Otherwise
-	this is the default value for 'encoding'.  It is useful when
-	'encoding' is set to "utf-8" and your environment uses a non-latin1
-	encoding, such as Russian.
-	When 'encoding' is "utf-8" and a file contains an illegal byte
-	sequence it won't be recognized as UTF-8.  You can use the |8g8|
-	command to find the illegal byte sequence.
-	WRONG VALUES:			WHAT'S WRONG:
-		latin1,utf-8		"latin1" will always be used
-		utf-8,ucs-bom,latin1	BOM won't be recognized in an utf-8
-					file
-		cp1250,latin1		"cp1250" will always be used
-	If 'fileencodings' is empty, 'fileencoding' is not modified.
-	See 'fileencoding' for the possible values.
-	Setting this option does not have an effect until the next time a file
-	is read.
-
-					*'fileformat'* *'ff'*
-'fileformat' 'ff'	string (MS-Windows default: "dos",
-				Unix, macOS default: "unix")
-			local to buffer
-	This gives the <EOL> of the current buffer, which is used for
-	reading/writing the buffer from/to a file:
-	    dos	    <CR><NL>
-	    unix    <NL>
-	    mac	    <CR>
-	When "dos" is used, CTRL-Z at the end of a file is ignored.
-	See |file-formats| and |file-read|.
-	For the character encoding of the file see 'fileencoding'.
-	When 'binary' is set, the value of 'fileformat' is ignored, file I/O
-	works like it was set to "unix".
-	This option is set automatically when starting to edit a file and
-	'fileformats' is not empty and 'binary' is off.
-	When this option is set, after starting to edit a file, the 'modified'
-	option is set, because the file would be different when written.
-	This option can not be changed when 'modifiable' is off.
-	For backwards compatibility: When this option is set to "dos",
-	'textmode' is set, otherwise 'textmode' is reset.
-
-					*'fileformats'* *'ffs'*
-'fileformats' 'ffs'	string (default:
-				Vim+Vi	MS-Windows: "dos,unix",
-				Vim	Unix, macOS: "unix,dos",
-				Vi	Cygwin: "unix,dos",
-				Vi	others: "")
-			global
-	This gives the end-of-line (<EOL>) formats that will be tried when
-	starting to edit a new buffer and when reading a file into an existing
-	buffer:
-	- When empty, the format defined with 'fileformat' will be used
-	  always.  It is not set automatically.
-	- When set to one name, that format will be used whenever a new buffer
-	  is opened.  'fileformat' is set accordingly for that buffer.  The
-	  'fileformats' name will be used when a file is read into an existing
-	  buffer, no matter what 'fileformat' for that buffer is set to.
-	- When more than one name is present, separated by commas, automatic
-	  <EOL> detection will be done when reading a file.  When starting to
-	  edit a file, a check is done for the <EOL>:
-	  1. If all lines end in <CR><NL>, and 'fileformats' includes "dos",
-	     'fileformat' is set to "dos".
-	  2. If a <NL> is found and 'fileformats' includes "unix", 'fileformat'
-	     is set to "unix".  Note that when a <NL> is found without a
-	     preceding <CR>, "unix" is preferred over "dos".
-	  3. If 'fileformat' has not yet been set, and if a <CR> is found, and
-	     if 'fileformats' includes "mac", 'fileformat' is set to "mac".
-	     This means that "mac" is only chosen when:
-	      "unix" is not present or no <NL> is found in the file, and
-	      "dos" is not present or no <CR><NL> is found in the file.
-	     Except: if "unix" was chosen, but there is a <CR> before
-	     the first <NL>, and there appear to be more <CR>s than <NL>s in
-	     the first few lines, "mac" is used.
-	  4. If 'fileformat' is still not set, the first name from
-	     'fileformats' is used.
-	  When reading a file into an existing buffer, the same is done, but
-	  this happens like 'fileformat' has been set appropriately for that
-	  file only, the option is not changed.
-	When 'binary' is set, the value of 'fileformats' is not used.
-
-	When Vim starts up with an empty buffer the first item is used.  You
-	can overrule this by setting 'fileformat' in your .vimrc.
-
-	For systems with a Dos-like <EOL> (<CR><NL>), when reading files that
-	are ":source"ed and for vimrc files, automatic <EOL> detection may be
-	done:
-	- When 'fileformats' is empty, there is no automatic detection.  Dos
-	  format will be used.
-	- When 'fileformats' is set to one or more names, automatic detection
-	  is done.  This is based on the first <NL> in the file: If there is a
-	  <CR> in front of it, Dos format is used, otherwise Unix format is
-	  used.
-	Also see |file-formats|.
-	For backwards compatibility: When this option is set to an empty
-	string or one format (no comma is included), 'textauto' is reset,
-	otherwise 'textauto' is set.
-	NOTE: This option is set to the Vi default value when 'compatible' is
-	set and to the Vim default value when 'compatible' is reset.
-
-		*'fileignorecase'* *'fic'* *'nofileignorecase'* *'nofic'*
-'fileignorecase' 'fic'	boolean	(default on for systems where case in file
-				 names is normally ignored)
-			global
-	When set case is ignored when using file names and directories.
-	See 'wildignorecase' for only ignoring case when doing completion.
-
-					*'filetype'* *'ft'*
-'filetype' 'ft'		string (default: "")
-			local to buffer
-	When this option is set, the FileType autocommand event is triggered.
-	All autocommands that match with the value of this option will be
-	executed.  Thus the value of 'filetype' is used in place of the file
-	name.
-	Otherwise this option does not always reflect the current file type.
-	This option is normally set when the file type is detected.  To enable
-	this use the ":filetype on" command. |:filetype|
-	Setting this option to a different value is most useful in a modeline,
-	for a file for which the file type is not automatically recognized.
-	Example, for in an IDL file:
-		/* vim: set filetype=idl : */ ~
-	|FileType| |filetypes|
-	When a dot appears in the value then this separates two filetype
-	names.  Example:
-		/* vim: set filetype=c.doxygen : */ ~
-	This will use the "c" filetype first, then the "doxygen" filetype.
-	This works both for filetype plugins and for syntax files.  More than
-	one dot may appear.
-	This option is not copied to another buffer, independent of the 's' or
-	'S' flag in 'cpoptions'.
-	Only normal file name characters can be used, "/\*?[|<>" are illegal.
-
-						*'fillchars'* *'fcs'*
-'fillchars' 'fcs'	string	(default "vert:|,fold:-,eob:~")
-			global or local to window |global-local|
-			{not available when compiled without the |+folding|
-			feature}
-	Characters to fill the statuslines, vertical separators and special
-	lines in the window.
-	It is a comma-separated list of items.  Each item has a name, a colon
-	and the value of that item:
-
-	  item name	default		Used for ~
-	  stl		' ' or '^'	statusline of the current window
-	  stlnc		' ' or '='	statusline of the non-current windows
-	  vert		'|'		vertical separators |:vsplit|
-	  fold		'-'		filling 'foldtext'
-	  foldopen	'-'		mark the beginning of a fold
-	  foldclose	'+'		show a closed fold
-	  foldsep	'|'		open fold middle character
-	  diff		'-'		deleted lines of the 'diff' option
-	  eob		'~'		empty lines below the end of a buffer
-	  lastline	'@'		'display' contains lastline/truncate
-
-	Any one that is omitted will fall back to the default.  For "stl" and
-	"stlnc" the space will be used when there is highlighting, '^' or '='
-	otherwise.
-
-	Example: >
-	    :set fillchars=stl:^,stlnc:=,vert:\|,fold:-,diff:-
-<	This is similar to the default, except that these characters will also
-	be used when there is highlighting.
-
-	For the "stl", "stlnc", "foldopen", "foldclose" and "foldsep" items
-	single-byte and multibyte characters are supported.  But double-width
-	characters are not supported.
-
-	The highlighting used for these items:
-	  item name	highlight group ~
-	  stl		StatusLine		|hl-StatusLine|
-	  stlnc		StatusLineNC		|hl-StatusLineNC|
-	  vert		VertSplit		|hl-VertSplit|
-	  fold		Folded			|hl-Folded|
-	  diff		DiffDelete		|hl-DiffDelete|
-	  eob		EndOfBuffer		|hl-EndOfBuffer|
-	  lastline	NonText			|hl-NonText|
-
-		*'fixendofline'* *'fixeol'* *'nofixendofline'* *'nofixeol'*
-'fixendofline' 'fixeol'	boolean	(default on)
-			local to buffer
-	When writing a file and this option is on, <EOL> at the end of file
-	will be restored if missing.  Turn this option off if you want to
-	preserve the situation from the original file.
-	When the 'binary' option is set the value of this option doesn't
-	matter.
-	See the 'endofline' option.
-	See |eol-and-eof| for example settings.
-
-					*'fkmap'* *'fk'* *'nofkmap'* *'nofk'*
-'fkmap' 'fk'		boolean (default off)
-			global
-			{only available when compiled with the |+rightleft|
-			feature}
-	This option was for using Farsi, which has been removed.  See
-	|farsi.txt|.
-
-						*'foldclose'* *'fcl'*
-'foldclose' 'fcl'	string (default "")
-			global
-			{not available when compiled without the |+folding|
-			feature}
-	When set to "all", a fold is closed when the cursor isn't in it and
-	its level is higher than 'foldlevel'.  Useful if you want folds to
-	automatically close when moving out of them.
-
-						*'foldcolumn'* *'fdc'*
-'foldcolumn' 'fdc'	number (default 0)
-			local to window
-			{not available when compiled without the |+folding|
-			feature}
-	When non-zero, a column with the specified width is shown at the side
-	of the window which indicates open and closed folds.  The maximum
-	value is 12.
-	See |folding|.
-
-			*'foldenable'* *'fen'* *'nofoldenable'* *'nofen'*
-'foldenable' 'fen'	boolean (default on)
-			local to window
-			{not available when compiled without the |+folding|
-			feature}
-	When off, all folds are open.  This option can be used to quickly
-	switch between showing all text unfolded and viewing the text with
-	folds (including manually opened or closed folds).  It can be toggled
-	with the |zi| command.  The 'foldcolumn' will remain blank when
-	'foldenable' is off.
-	This option is set by commands that create a new fold or close a fold.
-	See |folding|.
-
-						*'foldexpr'* *'fde'*
-'foldexpr' 'fde'	string (default: "0")
-			local to window
-			{not available when compiled without the |+folding|
-			or |+eval| features}
-	The expression used for when 'foldmethod' is "expr".  It is evaluated
-	for each line to obtain its fold level.  The context is set to the
-	script where 'foldexpr' was set, script-local items can be accessed.
-	See |fold-expr| for the usage.
-
-	The expression will be evaluated in the |sandbox| if set from a
-	modeline, see |sandbox-option|.
-	This option can't be set from a |modeline| when the 'diff' option is
-	on or the 'modelineexpr' option is off.
-
-	It is not allowed to change text or jump to another window while
-	evaluating 'foldexpr' |textlock|.
-
-						*'foldignore'* *'fdi'*
-'foldignore' 'fdi'	string (default: "#")
-			local to window
-			{not available when compiled without the |+folding|
-			feature}
-	Used only when 'foldmethod' is "indent".  Lines starting with
-	characters in 'foldignore' will get their fold level from surrounding
-	lines.  White space is skipped before checking for this character.
-	The default "#" works well for C programs.  See |fold-indent|.
-
-						*'foldlevel'* *'fdl'*
-'foldlevel' 'fdl'	number (default: 0)
-			local to window
-			{not available when compiled without the |+folding|
-			feature}
-	Sets the fold level: Folds with a higher level will be closed.
-	Setting this option to zero will close all folds.  Higher numbers will
-	close fewer folds.
-	This option is set by commands like |zm|, |zM| and |zR|.
-	See |fold-foldlevel|.
-
-						*'foldlevelstart'* *'fdls'*
-'foldlevelstart' 'fdls'	number (default: -1)
-			global
-			{not available when compiled without the |+folding|
-			feature}
-	Sets 'foldlevel' when starting to edit another buffer in a window.
-	Useful to always start editing with all folds closed (value zero),
-	some folds closed (one) or no folds closed (99).
-	This is done before reading any modeline, thus a setting in a modeline
-	overrules this option.  Starting to edit a file for |diff-mode| also
-	ignores this option and closes all folds.
-	It is also done before BufReadPre autocommands, to allow an autocmd to
-	overrule the 'foldlevel' value for specific files.
-	When the value is negative, it is not used.
-
-						*'foldmarker'* *'fmr'* *E536*
-'foldmarker' 'fmr'	string (default: "{{{,}}}")
-			local to window
-			{not available when compiled without the |+folding|
-			feature}
-	The start and end marker used when 'foldmethod' is "marker".  There
-	must be one comma, which separates the start and end marker.  The
-	marker is a literal string (a regular expression would be too slow).
-	See |fold-marker|.
-
-						*'foldmethod'* *'fdm'*
-'foldmethod' 'fdm'	string (default: "manual")
-			local to window
-			{not available when compiled without the |+folding|
-			feature}
-	The kind of folding used for the current window.  Possible values:
-	|fold-manual|	manual	    Folds are created manually.
-	|fold-indent|	indent	    Lines with equal indent form a fold.
-	|fold-expr|	expr	    'foldexpr' gives the fold level of a line.
-	|fold-marker|	marker	    Markers are used to specify folds.
-	|fold-syntax|	syntax	    Syntax highlighting items specify folds.
-	|fold-diff|	diff	    Fold text that is not changed.
-
-						*'foldminlines'* *'fml'*
-'foldminlines' 'fml'	number (default: 1)
-			local to window
-			{not available when compiled without the |+folding|
-			feature}
-	Sets the number of screen lines above which a fold can be displayed
-	closed.  Also for manually closed folds.  With the default value of
-	one a fold can only be closed if it takes up two or more screen lines.
-	Set to zero to be able to close folds of just one screen line.
-	Note that this only has an effect on what is displayed.  After using
-	"zc" to close a fold, which is displayed open because it's smaller
-	than 'foldminlines', a following "zc" may close a containing fold.
-
-						*'foldnestmax'* *'fdn'*
-'foldnestmax' 'fdn'	number (default: 20)
-			local to window
-			{not available when compiled without the |+folding|
-			feature}
-	Sets the maximum nesting of folds for the "indent" and "syntax"
-	methods.  This avoids that too many folds will be created.  Using more
-	than 20 doesn't work, because the internal limit is 20.
-
-						*'foldopen'* *'fdo'*
-'foldopen' 'fdo'	string (default: "block,hor,mark,percent,quickfix,
-							     search,tag,undo")
-			global
-			{not available when compiled without the |+folding|
-			feature}
-	Specifies for which type of commands folds will be opened, if the
-	command moves the cursor into a closed fold.  It is a comma-separated
-	list of items.
-	NOTE: When the command is part of a mapping this option is not used.
-	Add the |zv| command to the mapping to get the same effect.
-	(rationale: the mapping may want to control opening folds itself)
-
-		item		commands ~
-		all		any
-		block		"(", "{", "[[", "[{", etc.
-		hor		horizontal movements: "l", "w", "fx", etc.
-		insert		any command in Insert mode
-		jump		far jumps: "G", "gg", etc.
-		mark		jumping to a mark: "'m", CTRL-O, etc.
-		percent		"%"
-		quickfix	":cn", ":crew", ":make", etc.
-		search		search for a pattern: "/", "n", "*", "gd", etc.
-				(not for a search pattern in a ":" command)
-				Also for |[s| and |]s|.
-		tag		jumping to a tag: ":ta", CTRL-T, etc.
-		undo		undo or redo: "u" and CTRL-R
-	When a movement command is used for an operator (e.g., "dl" or "y%")
-	this option is not used.  This means the operator will include the
-	whole closed fold.
-	Note that vertical movements are not here, because it would make it
-	very difficult to move onto a closed fold.
-	In insert mode the folds containing the cursor will always be open
-	when text is inserted.
-	To close folds you can re-apply 'foldlevel' with the |zx| command or
-	set the 'foldclose' option to "all".
-
-						*'foldtext'* *'fdt'*
-'foldtext' 'fdt'	string (default: "foldtext()")
-			local to window
-			{not available when compiled without the |+folding|
-			feature}
-	An expression which is used to specify the text displayed for a closed
-	fold.  The context is set to the script where 'foldexpr' was set,
-	script-local items can be accessed.  See |fold-foldtext| for the
-	usage.
-
-	The expression will be evaluated in the |sandbox| if set from a
-	modeline, see |sandbox-option|.
-	This option cannot be set in a modeline when 'modelineexpr' is off.
-
-	It is not allowed to change text or jump to another window while
-	evaluating 'foldtext' |textlock|.
-
-						*'formatexpr'* *'fex'*
-'formatexpr' 'fex'	string (default "")
-			local to buffer
-			{not available when compiled without the |+eval|
-			feature}
-	Expression which is evaluated to format a range of lines for the |gq|
-	operator or automatic formatting (see 'formatoptions').  When this
-	option is empty 'formatprg' is used.
-
-	The |v:lnum|  variable holds the first line to be formatted.
-	The |v:count| variable holds the number of lines to be formatted.
-	The |v:char|  variable holds the character that is going to be
-		      inserted if the expression is being evaluated due to
-		      automatic formatting.  This can be empty.  Don't insert
-		      it yet!
-
-	Example: >
-		:set formatexpr=mylang#Format()
-<	This will invoke the mylang#Format() function in the
-	autoload/mylang.vim file in 'runtimepath'. |autoload|
-
-	The advantage of using a function call without arguments is that it is
-	faster, see |expr-option-function|.
-
-	The expression is also evaluated when 'textwidth' is set and adding
-	text beyond that limit.  This happens under the same conditions as
-	when internal formatting is used.  Make sure the cursor is kept in the
-	same spot relative to the text then!  The |mode()| function will
-	return "i" or "R" in this situation.
-
-	When the expression evaluates to non-zero Vim will fall back to using
-	the internal format mechanism.
-
-	If the expression starts with s: or |<SID>|, then it is replaced with
-	the script ID (|local-function|). Example: >
-		set formatexpr=s:MyFormatExpr()
-		set formatexpr=<SID>SomeFormatExpr()
-<	Otherwise, the expression is evaluated in the context of the script
-	where the option was set, thus script-local items are available.
-
-	The expression will be evaluated in the |sandbox| when set from a
-	modeline, see |sandbox-option|.  That stops the option from working,
-	since changing the buffer text is not allowed.
-	This option cannot be set in a modeline when 'modelineexpr' is off.
-	NOTE: This option is set to "" when 'compatible' is set.
-
-					*'formatlistpat'* *'flp'*
-'formatlistpat' 'flp'	string (default: "^\s*\d\+[\]:.)}\t ]\s*")
-			local to buffer
-	A pattern that is used to recognize a list header.  This is used for
-	the "n" flag in 'formatoptions'.
-	The pattern must match exactly the text that will be the indent for
-	the line below it.  You can use |/\ze| to mark the end of the match
-	while still checking more characters.  There must be a character
-	following the pattern, when it matches the whole line it is handled
-	like there is no match.
-	The default recognizes a number, followed by an optional punctuation
-	character and white space.
-
-					*'formatoptions'* *'fo'*
-'formatoptions' 'fo'	string (Vim default: "tcq", Vi default: "vt")
-			local to buffer
-	This is a sequence of letters which describes how automatic
-	formatting is to be done.  See |fo-table|.  When the 'paste' option is
-	on, no formatting is done (like 'formatoptions' is empty).  Commas can
-	be inserted for readability.
-	To avoid problems with flags that are added in the future, use the
-	"+=" and "-=" feature of ":set" |add-option-flags|.
-	NOTE: This option is set to the Vi default value when 'compatible' is
-	set and to the Vim default value when 'compatible' is reset.
-
-						*'formatprg'* *'fp'*
-'formatprg' 'fp'	string (default "")
-			global or local to buffer |global-local|
-	The name of an external program that will be used to format the lines
-	selected with the |gq| operator.  The program must take the input on
-	stdin and produce the output on stdout.  The Unix program "fmt" is
-	such a program.
-	If the 'formatexpr' option is not empty it will be used instead.
-	Otherwise, if 'formatprg' option is an empty string, the internal
-	format function will be used |C-indenting|.
-	Environment variables are expanded |:set_env|.  See |option-backslash|
-	about including spaces and backslashes.
-	This option cannot be set from a |modeline| or in the |sandbox|, for
-	security reasons.
-
-					*'fsync'* *'fs'* *'nofsync'* *'nofs'*
-'fsync' 'fs'		boolean	(default on)
-			global
-	When on, the library function fsync() will be called after writing a
-	file.  This will flush a file to disk, ensuring that it is safely
-	written even on filesystems which do metadata-only journaling.  This
-	will force the harddrive to spin up on Linux systems running in laptop
-	mode, so it may be undesirable in some situations.  Be warned that
-	turning this off increases the chances of data loss after a crash.  On
-	systems without an fsync() implementation, this variable is always
-	off.
-	Also see 'swapsync' for controlling fsync() on swap files.
-	'fsync' also applies to |writefile()| (unless a flag is used to
-	overrule it) and when writing undo files (see |undo-persistence|).
-	This option cannot be set from a |modeline| or in the |sandbox|, for
-	security reasons.
-
-				   *'gdefault'* *'gd'* *'nogdefault'* *'nogd'*
-'gdefault' 'gd'		boolean	(default off)
-			global
-	When on, the ":substitute" flag 'g' is default on.  This means that
-	all matches in a line are substituted instead of one.  When a 'g' flag
-	is given to a ":substitute" command, this will toggle the substitution
-	of all or one match.  See |complex-change|.
-
-		command		'gdefault' on	'gdefault' off	~
-		:s///		  subst. all	  subst. one
-		:s///g		  subst. one	  subst. all
-		:s///gg		  subst. all	  subst. one
-
-	NOTE: This option is reset when 'compatible' is set.
-	DEPRECATED: Setting this option may break plugins that are not aware
-	of this option.  Also, many users get confused that adding the /g flag
-	has the opposite effect of that it normally does.
-	This option is not used in |Vim9| script.
-
-						*'grepformat'* *'gfm'*
-'grepformat' 'gfm'	string	(default "%f:%l:%m,%f:%l%m,%f  %l%m")
-			global
-	Format to recognize for the ":grep" command output.
-	This is a scanf-like string that uses the same format as the
-	'errorformat' option: see |errorformat|.
-
-						*'grepprg'* *'gp'*
-'grepprg' 'gp'		string	(default "grep -n ",
-					Unix: "grep -n $* /dev/null",
-					Win32: "findstr /n" or "grep -n",
-						      VMS: "SEARCH/NUMBERS ")
-			global or local to buffer |global-local|
-	Program to use for the |:grep| command.  This option may contain '%'
-	and '#' characters, which are expanded like when used in a command-
-	line.  The placeholder "$*" is allowed to specify where the arguments
-	will be included.  Environment variables are expanded |:set_env|.  See
-	|option-backslash| about including spaces and backslashes.
-	When your "grep" accepts the "-H" argument, use this to make ":grep"
-	also work well with a single file: >
-		:set grepprg=grep\ -nH
-<	Special value: When 'grepprg' is set to "internal" the |:grep| command
-	works like |:vimgrep|, |:lgrep| like |:lvimgrep|, |:grepadd| like
-	|:vimgrepadd| and |:lgrepadd| like |:lvimgrepadd|.
-	See also the section |:make_makeprg|, since most of the comments there
-	apply equally to 'grepprg'.
-	For Win32, the default is "findstr /n" if "findstr.exe" can be found,
-	otherwise it's "grep -n".
-	This option cannot be set from a |modeline| or in the |sandbox|, for
-	security reasons.
-
-			*'guicursor'* *'gcr'* *E545* *E546* *E548* *E549*
-'guicursor' 'gcr'	string	(default "n-v-c:block-Cursor/lCursor,

-					r-cr:hor30,sm:block")
-			global
-			{only available when compiled with GUI enabled, and
-			for Win32 console}
-	This option tells Vim what the cursor should look like in different
-	modes.  It fully works in the GUI.  In a Win32 console, only the
-	height of the cursor can be changed.  This can be done by specifying a
-	block cursor, or a percentage for a vertical or horizontal cursor.
-	For a console the 't_SI', 't_SR', and 't_EI' escape sequences are
-	used.
-
-	The option is a comma-separated list of parts.  Each part consist of a
-	mode-list and an argument-list:
-		mode-list:argument-list,mode-list:argument-list,..
-	The mode-list is a dash separated list of these modes:
-		n	Normal mode
-		v	Visual mode
-		ve	Visual mode with 'selection' "exclusive" (same as 'v',
-			if not specified)
-		o	Operator-pending mode
-		i	Insert mode
-		r	Replace mode
-		c	Command-line Normal (append) mode
-		ci	Command-line Insert mode
-		cr	Command-line Replace mode
-		sm	showmatch in Insert mode
-		a	all modes
-	The argument-list is a dash separated list of these arguments:
-		hor{N}	horizontal bar, {N} percent of the character height
-		ver{N}	vertical bar, {N} percent of the character width
-		block	block cursor, fills the whole character
-			[only one of the above three should be present]
-		blinkwait{N}				*cursor-blinking*
-		blinkon{N}
-		blinkoff{N}
-			blink times for cursor: blinkwait is the delay before
-			the cursor starts blinking, blinkon is the time that
-			the cursor is shown and blinkoff is the time that the
-			cursor is not shown.  The times are in msec.  When one
-			of the numbers is zero, there is no blinking.  The
-			default is: "blinkwait700-blinkon400-blinkoff250".
-			These numbers are used for a missing entry.  This
-			means that blinking is enabled by default.  To switch
-			blinking off you can use "blinkon0".  The cursor only
-			blinks when Vim is waiting for input, not while
-			executing a command.
-			To make the cursor blink in an xterm, see
-			|xterm-blink|.
-		{group-name}
-			a highlight group name, that sets the color and font
-			for the cursor
-		{group-name}/{group-name}
-			Two highlight group names, the first is used when
-			no language mappings are used, the other when they
-			are. |language-mapping|
-
-	Examples of parts:
-	   n-c-v:block-nCursor	in Normal, Command-line and Visual mode, use a
-				block cursor with colors from the "nCursor"
-				highlight group
-	   i-ci:ver30-iCursor-blinkwait300-blinkon200-blinkoff150
-				In Insert and Command-line Insert mode, use a
-				30% vertical bar cursor with colors from the
-				"iCursor" highlight group.  Blink a bit
-				faster.
-
-	The 'a' mode is different.  It will set the given argument-list for
-	all modes.  It does not reset anything to defaults.  This can be used
-	to do a common setting for all modes.  For example, to switch off
-	blinking: "a:blinkon0"

-	    :highlight Cursor gui=reverse guifg=NONE guibg=NONE
-	    :highlight Cursor gui=NONE guifg=bg guibg=fg

-						   *E235* *E596*
-'guifont' 'gfn'		string	(default "")
-			global
-			{only available when compiled with GUI enabled}
-	This is a list of fonts which will be used for the GUI version of Vim.
-	In its simplest form the value is just one font name.
-	See |gui-font| for the details.
-
-					*'guifontset'* *'gfs'*

-
-						*'guiheadroom'* *'ghr'*
-'guiheadroom' 'ghr'	number	(default 50)
-			global
-			{only for GTK and X11 GUI}
-	The number of pixels subtracted from the screen height when fitting
-	the GUI window on the screen.  Set this before the GUI is started,
-	e.g., in your |gvimrc| file.  When zero, the whole screen height will
-	be used by the window.  When positive, the specified number of pixel
-	lines will be left for window decorations and other items on the
-	screen.  Set it to a negative value to allow windows taller than the
-	screen.
-
-						*'guiligatures'* *'gli'* *E1243*
-'guiligatures' 'gli'	string	(default "")
-			global
-			{only for GTK GUI}
-	List of ASCII characters that, when combined together, can create more
-	complex shapes. Each character must be a printable ASCII character
-	with a value in the 32-127 range.
-	Example: >
-		:set guiligatures=!\"#$%&()*+-./:<=>?@[]^_{\|~
-<	Changing this option updates screen output immediately. Set it to an
-	empty string to disable ligatures.

-						*'guioptions'* *'go'*
-'guioptions' 'go'	string	(default "egmrLtT"   (MS-Windows,
-					   "t" is removed in |defaults.vim|),
-					 "aegimrLtT" (GTK and Motif),
-					 )
-			global
-			{only available when compiled with GUI enabled}
-	This option only has an effect in the GUI version of Vim.  It is a
-	sequence of letters which describes what components and options of the
-	GUI should be used.
-	To avoid problems with flags that are added in the future, use the
-	"+=" and "-=" feature of ":set" |add-option-flags|.
-
-	Valid characters are as follows:
-								*'go-!'*
-	  '!'	External commands are executed in a terminal window.  Without
-		this flag the MS-Windows GUI will open a console window to
-		execute the command.  The Unix GUI will simulate a dumb
-		terminal to list the command output.
-		The terminal window will be positioned at the bottom, and grow
-		upwards as needed.
-								*'go-a'*
-	  'a'	Autoselect:  If present, then whenever VISUAL mode is started,
-		or the Visual area extended, Vim tries to become the owner of
-		the windowing system's global selection.  This means that the
-		Visually highlighted text is available for pasting into other
-		applications as well as into Vim itself.  When the Visual mode
-		ends, possibly due to an operation on the text, or when an
-		application wants to paste the selection, the highlighted text
-		is automatically yanked into the "* selection register.
-		Thus the selection is still available for pasting into other
-		applications after the VISUAL mode has ended.
-		    If not present, then Vim won't become the owner of the
-		windowing system's global selection unless explicitly told to
-		by a yank or delete operation for the "* register.
-		The same applies to the modeless selection.
-								*'go-P'*
-	  'P'	Like autoselect but using the "+ register instead of the "*
-		register.
-								*'go-A'*
-	  'A'	Autoselect for the modeless selection.  Like 'a', but only
-		applies to the modeless selection.
-
-		    'guioptions'   autoselect Visual  autoselect modeless ~
-			 ""		 -			 -
-			 "a"		yes			yes
-			 "A"		 -			yes
-			 "aA"		yes			yes
-
-		When using a terminal see the 'clipboard' option.
-
-								*'go-c'*
-	  'c'	Use console dialogs instead of popup dialogs for simple
-		choices.
-								*'go-d'*
-	  'd'	Use dark theme variant if available. Currently only works for
-		GTK+ GUI.
-								*'go-e'*
-	  'e'	Add tab pages when indicated with 'showtabline'.
-		'guitablabel' can be used to change the text in the labels.
-		When 'e' is missing a non-GUI tab pages line may be used.
-		The GUI tabs are only supported on some systems, currently
-		GTK, Motif, Mac OS/X, Haiku, and MS-Windows.
-								*'go-f'*
-	  'f'	Foreground: Don't use fork() to detach the GUI from the shell
-		where it was started.  Use this for programs that wait for the
-		editor to finish (e.g., an e-mail program).  Alternatively you
-		can use "gvim -f" or ":gui -f" to start the GUI in the
-		foreground.  |gui-fork|
-		Note: Set this option in the vimrc file.  The forking may have
-		happened already when the |gvimrc| file is read.
-								*'go-i'*
-	  'i'	Use a Vim icon.  For GTK with KDE it is used in the left-upper
-		corner of the window.  It's black&white on non-GTK, because of
-		limitations of X11.  For a color icon, see |X11-icon|.
-								*'go-m'*
-	  'm'	Menu bar is present.
-								*'go-M'*
-	  'M'	The system menu "$VIMRUNTIME/menu.vim" is not sourced.  Note
-		that this flag must be added in the .vimrc file, before
-		switching on syntax or filetype recognition (when the |gvimrc|
-		file is sourced the system menu has already been loaded; the
-		`:syntax on` and `:filetype on` commands load the menu too).
-								*'go-g'*
-	  'g'	Grey menu items: Make menu items that are not active grey.  If
-		'g' is not included inactive menu items are not shown at all.
-								*'go-t'*
-	  't'	Include tearoff menu items.  Currently only works for Win32,
-		GTK+, and Motif 1.2 GUI.
-								*'go-T'*
-	  'T'	Include Toolbar.  Currently only in Win32, GTK+, Motif and
-		Photon GUIs.
-								*'go-r'*
-	  'r'	Right-hand scrollbar is always present.
-								*'go-R'*
-	  'R'	Right-hand scrollbar is present when there is a vertically
-		split window.
-								*'go-l'*
-	  'l'	Left-hand scrollbar is always present.
-								*'go-L'*
-	  'L'	Left-hand scrollbar is present when there is a vertically
-		split window.
-								*'go-b'*
-	  'b'	Bottom (horizontal) scrollbar is present.  Its size depends on
-		the longest visible line, or on the cursor line if the 'h'
-		flag is included. |gui-horiz-scroll|
-								*'go-h'*
-	  'h'	Limit horizontal scrollbar size to the length of the cursor
-		line.  Reduces computations. |gui-horiz-scroll|
-
-	And yes, you may even have scrollbars on the left AND the right if
-	you really want to :-).  See |gui-scrollbars| for more information.
-
-								*'go-v'*
-	  'v'	Use a vertical button layout for dialogs.  When not included,
-		a horizontal layout is preferred, but when it doesn't fit a
-		vertical layout is used anyway.  Not supported in GTK 3.
-								*'go-p'*
-	  'p'	Use Pointer callbacks for X11 GUI.  This is required for some
-		window managers.  If the cursor is not blinking or hollow at
-		the right moment, try adding this flag.  This must be done
-		before starting the GUI.  Set it in your |gvimrc|.  Adding or
-		removing it after the GUI has started has no effect.
-								*'go-F'*
-	  'F'	Add a footer.  Only for Motif.  See |gui-footer|.
-								*'go-k'*
-	  'k'	Keep the GUI window size when adding/removing a scrollbar, or
-		toolbar, tabline, etc.  Instead, the behavior is similar to
-		when the window is maximized and will adjust 'lines' and
-		'columns' to fit to the window.  Without the 'k' flag Vim will
-		try to keep 'lines' and 'columns' the same when adding and
-		removing GUI components.
-
-						*'guipty'* *'noguipty'*
-'guipty'		boolean	(default on)
-			global
-			{only available when compiled with GUI enabled}
-	Only in the GUI: If on, an attempt is made to open a pseudo-tty for
-	I/O to/from shell commands.  See |gui-pty|.
-
-						*'guitablabel'* *'gtl'*
-'guitablabel' 'gtl'	string	(default empty)
-			global
-			{only available when compiled with GUI enabled}
-	When non-empty describes the text to use in a label of the GUI tab
-	pages line.  When empty and when the result is empty Vim will use a
-	default label.  See |setting-guitablabel| for more info.
-
-	The format of this option is like that of 'statusline'.
-	'guitabtooltip' is used for the tooltip, see below.
-	The expression will be evaluated in the |sandbox| when set from a
-	modeline, see |sandbox-option|.
-	This option cannot be set in a modeline when 'modelineexpr' is off.
-
-	Only used when the GUI tab pages line is displayed.  'e' must be
-	present in 'guioptions'.  For the non-GUI tab pages line 'tabline' is
-	used.
-
-						*'guitabtooltip'* *'gtt'*
-'guitabtooltip' 'gtt'	string	(default empty)
-			global
-			{only available when compiled with GUI enabled}
-	When non-empty describes the text to use in a tooltip for the GUI tab
-	pages line.  When empty Vim will use a default tooltip.
-	This option is otherwise just like 'guitablabel' above.
-	You can include a line break.  Simplest method is to use |:let|: >
-		:let &guitabtooltip = "line one\nline two"
-<
-
-						*'helpfile'* *'hf'*
-'helpfile' 'hf'		string	(default (MS-Windows) "$VIMRUNTIME\doc\help.txt"
-					 (others) "$VIMRUNTIME/doc/help.txt")
-			global
-	Name of the main help file.  All distributed help files should be
-	placed together in one directory.  Additionally, all "doc" directories
-	in 'runtimepath' will be used.
-	Environment variables are expanded |:set_env|.  For example:
-	"$VIMRUNTIME/doc/help.txt".  If $VIMRUNTIME is not set, $VIM is also
-	tried.  Also see |$VIMRUNTIME| and |option-backslash| about including
-	spaces and backslashes.
-	This option cannot be set from a |modeline| or in the |sandbox|, for
-	security reasons.
-
-						*'helpheight'* *'hh'*
-'helpheight' 'hh'	number	(default 20)
-			global
-	Minimal initial height of the help window when it is opened with the
-	":help" command.  The initial height of the help window is half of the
-	current window, or (when the 'ea' option is on) the same as other
-	windows.  When the height is less than 'helpheight', the height is
-	set to 'helpheight'.  Set to zero to disable.
-
-						*'helplang'* *'hlg'*
-'helplang' 'hlg'	string	(default: messages language or empty)
-			global
-			{only available when compiled with the |+multi_lang|
-			feature}
-	Comma-separated list of languages.  Vim will use the first language
-	for which the desired help can be found.  The English help will always
-	be used as a last resort.  You can add "en" to prefer English over
-	another language, but that will only find tags that exist in that
-	language and not in the English help.
-	Example: >
-		:set helplang=de,it
-<	This will first search German, then Italian and finally English help
-	files.
-	When using |CTRL-]| and ":help!" in a non-English help file Vim will
-	try to find the tag in the current language before using this option.
-	See |help-translated|.
-
-				     *'hidden'* *'hid'* *'nohidden'* *'nohid'*
-'hidden' 'hid'		boolean	(default off)
-			global
-	When off a buffer is unloaded when it is |abandon|ed.  When on a
-	buffer becomes hidden when it is |abandon|ed.  If the buffer is still
-	displayed in another window, it does not become hidden, of course.
-
-	The commands that move through the buffer list sometimes make a buffer
-	hidden even if the 'hidden' option is off when these three are true:
-	- the buffer is modified
-	- 'autowrite' is off or writing is not possible
-	- the '!' flag was used
-	Also see |windows.txt|.
-
-	To only make one buffer hidden use the 'bufhidden' option.
-	This option is set for one command with ":hide {command}" |:hide|.
-	WARNING: It's easy to forget that you have changes in hidden buffers.
-	Think twice when using ":q!" or ":qa!".
-
-						*'highlight'* *'hl'*
-'highlight' 'hl'	string	(default (as a single string):

-				     z:StatusLineTerm,Z:StatusLineTermNC")
-			global
-	This option can be used to set highlighting mode for various
-	occasions.  It is a comma-separated list of character pairs.  The
-	first character in a pair gives the occasion, the second the mode to
-	use for that occasion.  The occasions are:
-	|hl-SpecialKey|	 8  Meta and special keys listed with ":map"
-	|hl-EndOfBuffer|   ~  lines after the last line in the buffer
-	|hl-NonText|	 @  '@' at the end of the window and

-	The default is used for occasions that are not included.
-	If you want to change what the display modes do, see |dos-colors|
-	for an example.
-	When using the ':' display mode, this must be followed by the name of
-	a highlight group.  A highlight group can be used to define any type
-	of highlighting, including using color.  See |:highlight| on how to
-	define one.  The default uses a different group for each occasion.
-	See |highlight-default| for the default highlight groups.
-
-						*'history'* *'hi'*
-'history' 'hi'		number	(Vim default: 50, Vi default: 0,
-						 set to 200 in |defaults.vim|)
-			global
-	A history of ":" commands, and a history of previous search patterns
-	is remembered.  This option decides how many entries may be stored in
-	each of these histories (see |cmdline-editing|).
-	The maximum value is 10000.
-	NOTE: This option is set to the Vi default value when 'compatible' is
-	set and to the Vim default value when 'compatible' is reset.
-
-					 *'hkmap'* *'hk'* *'nohkmap'* *'nohk'*
-'hkmap' 'hk'		boolean (default off)
-			global
-			{only available when compiled with the |+rightleft|
-			feature}
-	When on, the keyboard is mapped for the Hebrew character set.
-	Normally you would set 'allowrevins' and use CTRL-_ in insert mode to
-	toggle this option.  See |rileft.txt|.
-	NOTE: This option is reset when 'compatible' is set.
-
-				 *'hkmapp'* *'hkp'* *'nohkmapp'* *'nohkp'*
-'hkmapp' 'hkp'		boolean (default off)
-			global
-			{only available when compiled with the |+rightleft|
-			feature}
-	When on, phonetic keyboard mapping is used.  'hkmap' must also be on.
-	This is useful if you have a non-Hebrew keyboard.
-	See |rileft.txt|.
-	NOTE: This option is reset when 'compatible' is set.
-
-				 *'hlsearch'* *'hls'* *'nohlsearch'* *'nohls'*
-'hlsearch' 'hls'	boolean	(default off)
-			global
-			{not available when compiled without the
-			|+extra_search| feature}
-	When there is a previous search pattern, highlight all its matches.
-	The type of highlighting used can be set with the 'l' occasion in the
-	'highlight' option.  This uses the "Search" highlight group by
-	default.  Note that only the matching text is highlighted, any offsets
-	are not applied.  If the "CurSearch" highlight group is set then the
-	current match is highlighted with that.
-	See also: 'incsearch' and |:match|.
-	When you get bored looking at the highlighted matches, you can turn it
-	off with |:nohlsearch|.  This does not change the option value, as
-	soon as you use a search command, the highlighting comes back.
-	'redrawtime' specifies the maximum time spent on finding matches.
-	When the search pattern can match an end-of-line, Vim will try to
-	highlight all of the matched text.  However, this depends on where the
-	search starts.  This will be the first line in the window or the first
-	line below a closed fold.  A match in a previous line which is not
-	drawn may not continue in a newly drawn line.
-	You can specify whether the highlight status is restored on startup
-	with the 'h' flag in 'viminfo' |viminfo-h|.
-	NOTE: This option is reset when 'compatible' is set.
-
-						*'icon'* *'noicon'*
-'icon'			boolean	(default off, on when title can be restored)
-			global
-	When on, the icon text of the window will be set to the value of
-	'iconstring' (if it is not empty), or to the name of the file
-	currently being edited.  Only the last part of the name is used.
-	Overridden by the 'iconstring' option.
-	Only works if the terminal supports setting window icons (currently
-	only X11 GUI and terminals with a non-empty 't_IS' option - these are
-	Unix xterm and iris-ansi by default, where 't_IS' is taken from the
-	builtin termcap).
-	When Vim was compiled with HAVE_X11 defined, the original icon will be
-	restored if possible |X11|.  See |X11-icon| for changing the icon on
-	X11.
-	For MS-Windows the icon can be changed, see |windows-icon|.
-
-						*'iconstring'*
-'iconstring'		string	(default "")
-			global
-	When this option is not empty, it will be used for the icon text of
-	the window.  This happens only when the 'icon' option is on.
-	Only works if the terminal supports setting window icon text
-	(currently only X11 GUI and terminals with a non-empty 't_IS' option).
-	Does not work for MS-Windows.
-	When Vim was compiled with HAVE_X11 defined, the original icon will be
-	restored if possible |X11|.
-	When this option contains printf-style '%' items, they will be
-	expanded according to the rules used for 'statusline'.  See
-	'titlestring' for example settings.
-	This option cannot be set in a modeline when 'modelineexpr' is off.
-	{not available when compiled without the |+statusline| feature}
-
-			*'ignorecase'* *'ic'* *'noignorecase'* *'noic'*
-'ignorecase' 'ic'	boolean	(default off)
-			global
-	Ignore case in search patterns.  Also used when searching in the tags
-	file.
-	Also see 'smartcase' and 'tagcase'.
-	Can be overruled by using "\c" or "\C" in the pattern, see
-	|/ignorecase|.
-
-						*'imactivatefunc'* *'imaf'*
-'imactivatefunc' 'imaf'	string (default "")
-			global
-	This option specifies a function that will be called to
-	activate or deactivate the Input Method.  The value can be the name of
-	a function, a |lambda| or a |Funcref|. See |option-value-function| for
-	more information.
-	It is not used in the MS-Windows GUI version.
-	The expression will be evaluated in the |sandbox| when set from a
-	modeline, see |sandbox-option|.
-
-	Example: >
-		function ImActivateFunc(active)
-		  if a:active
-		    ... do something
-		  else
-		    ... do something
-		  endif
-		  " return value is not used
-		endfunction
-		set imactivatefunc=ImActivateFunc
-<
-						*'imactivatekey'* *'imak'*
-'imactivatekey' 'imak'	string (default "")
-			global
-			{only available when compiled with |+xim| and
-			|+GUI_GTK|}				*E599*
-	Specifies the key that your Input Method in X-Windows uses for
-	activation.  When this is specified correctly, vim can fully control
-	IM with 'imcmdline', 'iminsert' and 'imsearch'.
-	You can't use this option to change the activation key, the option
-	tells Vim what the key is.
-	Format:
-		[MODIFIER_FLAG-]KEY_STRING
-
-	These characters can be used for MODIFIER_FLAG (case is ignored):
-		S	    Shift key
-		L	    Lock key
-		C	    Control key
-		1	    Mod1 key
-		2	    Mod2 key
-		3	    Mod3 key
-		4	    Mod4 key
-		5	    Mod5 key
-	Combinations are allowed, for example "S-C-space" or "SC-space" are
-	both shift+ctrl+space.
-	See <X11/keysymdef.h> and XStringToKeysym for KEY_STRING.
-
-	Example: >
-		:set imactivatekey=S-space
-<	"S-space" means shift+space.  This is the activation key for kinput2 +
-	canna (Japanese), and ami (Korean).
-
-				*'imcmdline'* *'imc'* *'noimcmdline'* *'noimc'*
-'imcmdline' 'imc'	boolean (default off)
-			global
-	When set the Input Method is always on when starting to edit a command
-	line, unless entering a search pattern (see 'imsearch' for that).
-	Setting this option is useful when your input method allows entering
-	English characters directly, e.g., when it's used to type accented
-	characters with dead keys.
-
-				*'imdisable'* *'imd'* *'noimdisable'* *'noimd'*
-'imdisable' 'imd'	boolean (default off, on for some systems (SGI))
-			global
-	When set the Input Method is never used.  This is useful to disable
-	the IM when it doesn't work properly.
-	Currently this option is on by default for SGI/IRIX machines.  This
-	may change in later releases.
-
-						*'iminsert'* *'imi'*
-'iminsert' 'imi'	number (default 0)
-			local to buffer
-	Specifies whether :lmap or an Input Method (IM) is to be used in
-	Insert mode.  Valid values:
-		0	:lmap is off and IM is off
-		1	:lmap is ON and IM is off
-		2	:lmap is off and IM is ON
-	To always reset the option to zero when leaving Insert mode with <Esc>
-	this can be used: >
-		:inoremap <ESC> <ESC>:set iminsert=0<CR>
-<	This makes :lmap and IM turn off automatically when leaving Insert
-	mode.
-	Note that this option changes when using CTRL-^ in Insert mode
-	|i_CTRL-^|.
-	The value is set to 1 when setting 'keymap' to a valid keymap name.
-	It is also used for the argument of commands like "r" and "f".
-	The value 0 may not work correctly with Motif with some XIM
-	methods.  Use 'imdisable' to disable XIM then.
-
-	You can set 'imactivatefunc' and 'imstatusfunc' to handle IME/XIM
-	via external command if Vim is not compiled with the |+xim|,
-	|+multi_byte_ime| or |global-ime|.
-
-						*'imsearch'* *'ims'*
-'imsearch' 'ims'	number (default -1)
-			local to buffer
-	Specifies whether :lmap or an Input Method (IM) is to be used when
-	entering a search pattern.  Valid values:
-		-1	the value of 'iminsert' is used, makes it look like
-			'iminsert' is also used when typing a search pattern
-		0	:lmap is off and IM is off
-		1	:lmap is ON and IM is off
-		2	:lmap is off and IM is ON
-	Note that this option changes when using CTRL-^ in Command-line mode
-	|c_CTRL-^|.
-	The value is set to 1 when it is not -1 and setting the 'keymap'
-	option to a valid keymap name.
-	The value 0 may not work correctly with Motif with some XIM
-	methods.  Use 'imdisable' to disable XIM then.
-
-						*'imstatusfunc'* *'imsf'*
-'imstatusfunc' 'imsf'	string (default "")
-			global
-	This option specifies a function that is called to obtain the status
-	of Input Method.  It must return a positive number when IME is active.
-	The value can be the name of a function, a |lambda| or a |Funcref|.
-	See |option-value-function| for more information.
-	It is not used in the MS-Windows GUI version.
-
-	Example: >
-		function ImStatusFunc()
-		  let is_active = ...do something
-		  return is_active ? 1 : 0
-		endfunction
-		set imstatusfunc=ImStatusFunc
-<
-	NOTE: This function is invoked very often.  Keep it fast.
-	The expression will be evaluated in the |sandbox| when set from a
-	modeline, see |sandbox-option|.
-
-						*'imstyle'* *'imst'*
-'imstyle' 'imst'	number (default 1)
-			global
-			{only available when compiled with |+xim| and
-			|+GUI_GTK|}
-	This option specifies the input style of Input Method:
-	0   use on-the-spot style
-	1   over-the-spot style
-	See: |xim-input-style|
-
-	For a long time on-the-spot style had been used in the GTK version of
-	vim, however, it is known that it causes troubles when using mappings,
-	|single-repeat|, etc.  Therefore over-the-spot style becomes the
-	default now.  This should work fine for most people, however if you
-	have any problem with it, try using on-the-spot style.
-	The expression will be evaluated in the |sandbox| when set from a
-	modeline, see |sandbox-option|.
-
-						*'include'* *'inc'*
-'include' 'inc'		string	(default "^\s*#\s*include")
-			global or local to buffer |global-local|
-			{not available when compiled without the
-			|+find_in_path| feature}
-	Pattern to be used to find an include command.  It is a search
-	pattern, just like for the "/" command (See |pattern|).  The default
-	value is for C programs.  This option is used for the commands "[i",
-	"]I", "[d", etc.
-	Normally the 'isfname' option is used to recognize the file name that
-	comes after the matched pattern.  But if "\zs" appears in the pattern
-	then the text matched from "\zs" to the end, or until "\ze" if it
-	appears, is used as the file name.  Use this to include characters
-	that are not in 'isfname', such as a space.  You can then use
-	'includeexpr' to process the matched text.
-	See |option-backslash| about including spaces and backslashes.
-
-						*'includeexpr'* *'inex'*
-'includeexpr' 'inex'	string	(default "")
-			local to buffer
-			{not available when compiled without the
-			|+find_in_path| or |+eval| features}
-	Expression to be used to transform the string found with the 'include'
-	option to a file name.  Mostly useful to change "." to "/" for Java: >
-		:setlocal includeexpr=substitute(v:fname,'\\.','/','g')
-<	The "v:fname" variable will be set to the file name that was detected.
-	Note the double backslash: the `:set` command first halves them, then
-	one remains it the value, where "\." matches a dot literally.  For
-	simple character replacements `tr()` avoids the need for escaping: >
-		:setlocal includeexpr=tr(v:fname,'.','/')
-<
-	Also used for the |gf| command if an unmodified file name can't be
-	found.  Allows doing "gf" on the name after an 'include' statement.
-	Also used for |<cfile>|.
-
-	If the expression starts with s: or |<SID>|, then it is replaced with
-	the script ID (|local-function|). Example: >
-		setlocal includeexpr=s:MyIncludeExpr()
-		setlocal includeexpr=<SID>SomeIncludeExpr()
-<	Otherwise, the expression is evaluated in the context of the script
-	where the option was set, thus script-local items are available.
-
-	It is more efficient if the value is just a function call without
-	arguments, see |expr-option-function|.
-
-	The expression will be evaluated in the |sandbox| when set from a
-	modeline, see |sandbox-option|.
-	This option cannot be set in a modeline when 'modelineexpr' is off.
-
-	It is not allowed to change text or jump to another window while
-	evaluating 'includeexpr' |textlock|.
-
-				 *'incsearch'* *'is'* *'noincsearch'* *'nois'*
-'incsearch' 'is'	boolean	(default off, set in |defaults.vim| if the
-					    |+reltime| feature is supported)
-			global
-			{not available when compiled without the
-			|+extra_search| features}
-	While typing a search command, show where the pattern, as it was typed
-	so far, matches.  The matched string is highlighted.  If the pattern
-	is invalid or not found, nothing is shown.  The screen will be updated
-	often, this is only useful on fast terminals.
-	Also applies to the pattern in commands: >
-		:global
-		:lvimgrep
-		:lvimgrepadd
-		:smagic
-		:snomagic
-		:sort
-		:substitute
-		:vglobal
-		:vimgrep
-		:vimgrepadd
-<	Note that the match will be shown, but the cursor will return to its
-	original position when no match is found and when pressing <Esc>.  You
-	still need to finish the search command with <Enter> to move the
-	cursor to the match.
-	You can use the CTRL-G and CTRL-T keys to move to the next and
-	previous match. |c_CTRL-G| |c_CTRL-T|
-	When compiled with the |+reltime| feature Vim only searches for about
-	half a second.  With a complicated pattern and/or a lot of text the
-	match may not be found.  This is to avoid that Vim hangs while you
-	are typing the pattern.
-	The highlighting can be set with the 'i' flag in 'highlight'.
-	When 'hlsearch' is on, all matched strings are highlighted too while
-	typing a search command. See also: 'hlsearch'.
-	If you don't want to turn 'hlsearch' on, but want to highlight all
-	matches while searching, you can turn on and off 'hlsearch' with
-	autocmd.  Example: >
-		augroup vimrc-incsearch-highlight
-		  autocmd!
-		  autocmd CmdlineEnter /,\? :set hlsearch
-		  autocmd CmdlineLeave /,\? :set nohlsearch
-		augroup END
-<
-	CTRL-L can be used to add one character from after the current match
-	to the command line.  If 'ignorecase' and 'smartcase' are set and the
-	command line has no uppercase characters, the added character is
-	converted to lowercase.
-	CTRL-R CTRL-W can be used to add the word at the end of the current
-	match, excluding the characters that were already typed.
-	NOTE: This option is reset when 'compatible' is set.
-
-						*'indentexpr'* *'inde'*
-'indentexpr' 'inde'	string	(default "")
-			local to buffer
-			{not available when compiled without the |+eval|
-			feature}
-	Expression which is evaluated to obtain the proper indent for a line.
-	It is used when a new line is created, for the |=| operator and
-	in Insert mode as specified with the 'indentkeys' option.
-	When this option is not empty, it overrules the 'cindent' and
-	'smartindent' indenting.  When 'lisp' is set, this option is
-	is only used when 'lispoptions' contains "expr:1".
-	When 'paste' is set this option is not used for indenting.
-	The expression is evaluated with |v:lnum| set to the line number for
-	which the indent is to be computed.  The cursor is also in this line
-	when the expression is evaluated (but it may be moved around).
-
-	If the expression starts with s: or |<SID>|, then it is replaced with
-	the script ID (|local-function|). Example: >
-		set indentexpr=s:MyIndentExpr()
-		set indentexpr=<SID>SomeIndentExpr()
-<	Otherwise, the expression is evaluated in the context of the script
-	where the option was set, thus script-local items are available.
-
-	The advantage of using a function call without arguments is that it is
-	faster, see |expr-option-function|.
-
-	The expression must return the number of spaces worth of indent.  It
-	can return "-1" to keep the current indent (this means 'autoindent' is
-	used for the indent).
-	Functions useful for computing the indent are |indent()|, |cindent()|
-	and |lispindent()|.
-	The evaluation of the expression must not have side effects!  It must
-	not change the text, jump to another window, etc.  Afterwards the
-	cursor position is always restored, thus the cursor may be moved.
-	Normally this option would be set to call a function: >
-		:set indentexpr=GetMyIndent()
-<	Error messages will be suppressed, unless the 'debug' option contains
-	"msg".
-	See |indent-expression|.
-	NOTE: This option is set to "" when 'compatible' is set.
-
-	The expression will be evaluated in the |sandbox| when set from a
-	modeline, see |sandbox-option|.
-	This option cannot be set in a modeline when 'modelineexpr' is off.
-
-	It is not allowed to change text or jump to another window while
-	evaluating 'indentexpr' |textlock|.
-
-
-						*'indentkeys'* *'indk'*
-'indentkeys' 'indk'	string	(default "0{,0},0),0],:,0#,!^F,o,O,e")
-			local to buffer
-	A list of keys that, when typed in Insert mode, cause reindenting of
-	the current line.  Only happens if 'indentexpr' isn't empty.
-	The format is identical to 'cinkeys', see |indentkeys-format|.
-	See |C-indenting| and |indent-expression|.
-
-			*'infercase'* *'inf'* *'noinfercase'* *'noinf'*
-'infercase' 'inf'	boolean	(default off)
-			local to buffer
-	When doing keyword completion in insert mode |ins-completion|, and
-	'ignorecase' is also on, the case of the match is adjusted depending
-	on the typed text.  If the typed text contains a lowercase letter
-	where the match has an upper case letter, the completed part is made
-	lowercase.  If the typed text has no lowercase letters and the match
-	has a lowercase letter where the typed text has an uppercase letter,
-	and there is a letter before it, the completed part is made uppercase.
-	With 'noinfercase' the match is used as-is.
-
-			*'insertmode'* *'im'* *'noinsertmode'* *'noim'*
-'insertmode' 'im'	boolean	(default off)
-			global
-	Makes Vim work in a way that Insert mode is the default mode.  Useful
-	if you want to use Vim as a modeless editor.  Used for |evim|.
-	These Insert mode commands will be useful:
-	- Use the cursor keys to move around.
-	- Use CTRL-O to execute one Normal mode command |i_CTRL-O|.  When
-	  this is a mapping, it is executed as if 'insertmode' was off.
-	  Normal mode remains active until the mapping is finished.
-	- Use CTRL-L to execute a number of Normal mode commands, then use
-	  <Esc> to get back to Insert mode.  Note that CTRL-L moves the cursor
-	  left, like <Esc> does when 'insertmode' isn't set.  |i_CTRL-L|
-
-	These items change when 'insertmode' is set:
-	- when starting to edit of a file, Vim goes to Insert mode.
-	- <Esc> in Insert mode is a no-op and beeps.
-	- <Esc> in Normal mode makes Vim go to Insert mode.
-	- CTRL-L in Insert mode is a command, it is not inserted.
-	- CTRL-Z in Insert mode suspends Vim, see |CTRL-Z|.	*i_CTRL-Z*
-	However, when <Esc> is used inside a mapping, it behaves like
-	'insertmode' was not set.  This was done to be able to use the same
-	mappings with 'insertmode' set or not set.
-	When executing commands with |:normal| 'insertmode' is not used.
-
-	NOTE: This option is reset when 'compatible' is set.
-
-						*'isfname'* *'isf'*
-'isfname' 'isf'		string	(default for Win32:
-			     "@,48-57,/,\,.,-,_,+,,,#,$,%,{,},[,],:,@-@,!,~,="
-			    for AMIGA: "@,48-57,/,.,-,_,+,,,$,:"
-			    for VMS: "@,48-57,/,.,-,_,+,,,#,$,%,<,>,[,],:,;,~"
-			    for OS/390: "@,240-249,/,.,-,_,+,,,#,$,%,~,="
-			    otherwise: "@,48-57,/,.,-,_,+,,,#,$,%,~,=")
-			global
-	The characters specified by this option are included in file names and
-	path names.  Filenames are used for commands like "gf", "[i" and in
-	the tags file.  It is also used for "\f" in a |pattern|.
-	Multi-byte characters 256 and above are always included, only the
-	characters up to 255 are specified with this option.
-	For UTF-8 the characters 0xa0 to 0xff are included as well.
-	Think twice before adding white space to this option.  Although a
-	space may appear inside a file name, the effect will be that Vim
-	doesn't know where a file name starts or ends when doing completion.
-	It most likely works better without a space in 'isfname'.
-
-	Note that on systems using a backslash as path separator, Vim tries to
-	do its best to make it work as you would expect.  That is a bit
-	tricky, since Vi originally used the backslash to escape special
-	characters.  Vim will not remove a backslash in front of a normal file
-	name character on these systems, but it will on Unix and alikes.  The
-	'&' and '^' are not included by default, because these are special for
-	cmd.exe.
-
-	The format of this option is a list of parts, separated with commas.
-	Each part can be a single character number or a range.  A range is two
-	character numbers with '-' in between.  A character number can be a
-	decimal number between 0 and 255 or the ASCII character itself (does
-	not work for digits).  Example:
-		"_,-,128-140,#-43"	(include '_' and '-' and the range
-					128 to 140 and '#' to 43)
-	If a part starts with '^', the following character number or range
-	will be excluded from the option.  The option is interpreted from left
-	to right.  Put the excluded character after the range where it is
-	included.  To include '^' itself use it as the last character of the
-	option or the end of a range.  Example:
-		"^a-z,#,^"	(exclude 'a' to 'z', include '#' and '^')
-	If the character is '@', all characters where isalpha() returns TRUE
-	are included.  Normally these are the characters a to z and A to Z,
-	plus accented characters.  To include '@' itself use "@-@".  Examples:
-		"@,^a-z"	All alphabetic characters, excluding lower
-				case ASCII letters.
-		"a-z,A-Z,@-@"	All letters plus the '@' character.
-	A comma can be included by using it where a character number is
-	expected.  Example:
-		"48-57,,,_"	Digits, comma and underscore.
-	A comma can be excluded by prepending a '^'.  Example:
-		" -~,^,,9"	All characters from space to '~', excluding
-				comma, plus <Tab>.
-	See |option-backslash| about including spaces and backslashes.
-
-						*'isident'* *'isi'*
-'isident' 'isi'		string	(default for Win32:
-					   "@,48-57,_,128-167,224-235"
-				otherwise: "@,48-57,_,192-255")
-			global
-	The characters given by this option are included in identifiers.
-	Identifiers are used in recognizing environment variables and after a
-	match of the 'define' option.  It is also used for "\i" in a
-	|pattern|.  See 'isfname' for a description of the format of this
-	option.  For '@' only characters up to 255 are used.
-	Careful: If you change this option, it might break expanding
-	environment variables.  E.g., when '/' is included and Vim tries to
-	expand "$HOME/.viminfo".  Maybe you should change 'iskeyword' instead.
-
-						*'iskeyword'* *'isk'*
-'iskeyword' 'isk'	string (Vim default for Win32:
-					    "@,48-57,_,128-167,224-235"
-				   otherwise:  "@,48-57,_,192-255"
-				Vi default: "@,48-57,_")
-			local to buffer
-	Keywords are used in searching and recognizing with many commands:
-	"w", "*", "[i", etc.  It is also used for "\k" in a |pattern|.  See
-	'isfname' for a description of the format of this option.  For '@'
-	characters above 255 check the "word" character class (any character
-	that is not white space or punctuation).
-	For C programs you could use "a-z,A-Z,48-57,_,.,-,>".
-	For a help file it is set to all non-blank printable characters except
-	'*', '"' and '|' (so that CTRL-] on a command finds the help for that
-	command).
-	When the 'lisp' option is on the '-' character is always included.
-	This option also influences syntax highlighting, unless the syntax
-	uses |:syn-iskeyword|.
-	NOTE: This option is set to the Vi default value when 'compatible' is
-	set and to the Vim default value when 'compatible' is reset.
-
-						*'isprint'* *'isp'*
-'isprint' 'isp'	string	(default for Win32 and macOS:
-				"@,~-255"; otherwise: "@,161-255")
-			global
-	The characters given by this option are displayed directly on the
-	screen.  It is also used for "\p" in a |pattern|.  The characters from
-	space (ASCII 32) to '~' (ASCII 126) are always displayed directly,
-	even when they are not included in 'isprint' or excluded.  See
-	'isfname' for a description of the format of this option.
-
-	Non-printable characters are displayed with two characters:
-		  0 -  31	"^@" - "^_"
-		 32 - 126	always single characters
-		   127		"^?"
-		128 - 159	"~@" - "~_"
-		160 - 254	"| " - "|~"
-		   255		"~?"
-	When 'encoding' is a Unicode one, illegal bytes from 128 to 255 are
-	displayed as <xx>, with the hexadecimal value of the byte.
-	When 'display' contains "uhex" all unprintable characters are
-	displayed as <xx>.
-	The SpecialKey highlighting will be used for unprintable characters.
-	|hl-SpecialKey|
-
-	Multi-byte characters 256 and above are always included, only the
-	characters up to 255 are specified with this option.  When a character
-	is printable but it is not available in the current font, a
-	replacement character will be shown.
-	Unprintable and zero-width Unicode characters are displayed as <xxxx>.
-	There is no option to specify these characters.
-
-			*'joinspaces'* *'js'* *'nojoinspaces'* *'nojs'*
-'joinspaces' 'js'	boolean	(default on)
-			global
-	Insert two spaces after a '.', '?' and '!' with a join command.
-	When 'cpoptions' includes the 'j' flag, only do this after a '.'.
-	Otherwise only one space is inserted.
-	NOTE: This option is set when 'compatible' is set.
-
-							*'key'*
-'key'			string	(default "")
-			local to buffer
-			{only available when compiled with the |+cryptv|
-			feature}
-	The key that is used for encrypting and decrypting the current buffer.
-	See |encryption| and 'cryptmethod'.
-	Careful: Do not set the key value by hand, someone might see the typed
-	key.  Use the |:X| command.  But you can make 'key' empty: >
-		:set key=
-<	It is not possible to get the value of this option with ":set key" or
-	"echo &key".  This is to avoid showing it to someone who shouldn't
-	know.  It also means you cannot see it yourself once you have set it,
-	be careful not to make a typing error!
-	You can use "&key" in an expression to detect whether encryption is
-	enabled.  When 'key' is set it returns "*****" (five stars).
-
-					*'keymap'* *'kmp'* *E544*
-'keymap' 'kmp'		string	(default "")
-			local to buffer
-			{only available when compiled with the |+keymap|
-			feature}
-	Name of a keyboard mapping.  See |mbyte-keymap|.
-	Setting this option to a valid keymap name has the side effect of
-	setting 'iminsert' to one, so that the keymap becomes effective.
-	'imsearch' is also set to one, unless it was -1
-	Only normal file name characters can be used, "/\*?[|<>" are illegal.
-
-					*'keymodel'* *'km'*
-'keymodel' 'km'		string	(default "")
-			global
-	List of comma-separated words, which enable special things that keys
-	can do.  These values can be used:
-	   startsel	Using a shifted special key starts selection (either
-			Select mode or Visual mode, depending on "key" being
-			present in 'selectmode').
-	   stopsel	Using a not-shifted special key stops selection.
-	Special keys in this context are the cursor keys, <End>, <Home>,
-	<PageUp> and <PageDown>.
-	The 'keymodel' option is set by the |:behave| command.
-
-						*'keyprotocol'* *'kpc'*
-'keyprotocol' 'kpc'	string	(default: see below)
-			global
-	Specifies what keyboard protocol to use depending on the value of
-	'term'.  The supported keyboard protocols names are:
-		none	whatever the terminal uses
-		mok2	modifyOtherKeys level 2, as supported by xterm
-		kitty	Kitty keyboard protocol, as supported by Kitty
-
-	The option value is a list of comma separated items.  Each item has
-	a pattern that is matched against the 'term' option, a colon and the
-	protocol name to be used.  To illustrate this, the default value would
-	be set with: >
-	   set keyprotocol=kitty:kitty,foot:kitty,wezterm:kitty,xterm:mok2
-
-<	This means that when 'term' contains "kitty, "foot" or "wezterm"
-	somewhere then the "kitty" protocol is used.  When 'term' contains
-	"xterm" somewhere, then the "mok2" protocol is used.
-
-	The first match is used, thus if you want to have "kitty" use the
-	kitty protocol, but "badkitty" not, then you should match "badkitty"
-	first and use the "none" value: >
-	   set keyprotocol=badkitty:none,kitty:kitty
-<
-	The option is used after 'term' has been changed.  First the termcap
-	entries are set, possibly using the builtin list, see |builtin-terms|.
-	Then this option is inspected and if there is a match and a protocol
-	is specified the following happens:
-		none	Nothing, the regular t_TE and t_TI values remain
-
-		mok2	The t_TE value is changed to:
-			    CSI >4;m	disables modifyOtherKeys
-			The t_TI value is changed to:
-			    CSI >4;2m	enables modifyOtherKeys
-			    CSI ?4m	request the modifyOtherKeys state
-
-		kitty	The t_TE value is changed to:
-			    CSI >4;m	disables modifyOtherKeys
-			    CSI =0;1u	disables the kitty keyboard protocol
-			The t_TI value is changed to:
-			    CSI =1;1u	enables the kitty keyboard protocol
-			    CSI ?u	request kitty keyboard protocol state
-			    CSI >c	request the termresponse
-
-	If you notice problems, such as characters being displayed that
-	disappear after `CTRL-L`, you might want to try making this option
-	empty.  Then set the 'term' option to have it take effect: >
-		set keyprotocol=
-		let &term = &term
-<
-
-					*'keywordprg'* *'kp'*
-'keywordprg' 'kp'	string	(default "man" or "man -s",  DOS: ":help",
-								  VMS: "help")
-			global or local to buffer |global-local|
-	Program to use for the |K| command.  Environment variables are
-	expanded |:set_env|.  ":help" may be used to access the Vim internal
-	help.  (Note that previously setting the global option to the empty
-	value did this, which is now deprecated.)
-	When the first character is ":", the command is invoked as a Vim
-	Ex command with [count] added as an argument if it is not zero.
-	When "man", "man -s" or an Ex command is used, Vim will automatically
-	translate a count for the "K" command and pass it as the first
-	argument.  For "man -s" the "-s" is removed when there is no count.
-	See |option-backslash| about including spaces and backslashes.
-	Example: >
-		:set keywordprg=man\ -s
-<	This option cannot be set from a |modeline| or in the |sandbox|, for
-	security reasons.
-
-					*'langmap'* *'lmap'* *E357* *E358*
-'langmap' 'lmap'	string	(default "")
-			global
-			{only available when compiled with the |+langmap|
-			feature}
-	This option allows switching your keyboard into a special language
-	mode.  When you are typing text in Insert mode the characters are
-	inserted directly.  When in Normal mode the 'langmap' option takes
-	care of translating these special characters to the original meaning
-	of the key.  This means you don't have to change the keyboard mode to
-	be able to execute Normal mode commands.
-	This is the opposite of the 'keymap' option, where characters are
-	mapped in Insert mode.
-	Also consider setting 'langremap' to off, to prevent 'langmap' from
-	applying to characters resulting from a mapping.
-	This option cannot be set from a |modeline| or in the |sandbox|, for
-	security reasons.
-
-	Example (for Greek, in UTF-8):				*greek*  >
-	    :set langmap=ΑA,ΒB,ΨC,ΔD,ΕE,ΦF,ΓG,ΗH,ΙI,ΞJ,ΚK,ΛL,ΜM,ΝN,ΟO,ΠP,QQ,ΡR,ΣS,ΤT,ΘU,ΩV,WW,ΧX,ΥY,ΖZ,αa,βb,ψc,δd,εe,φf,γg,ηh,ιi,ξj,κk,λl,μm,νn,οo,πp,qq,ρr,σs,τt,θu,ωv,ςw,χx,υy,ζz
-<	Example (exchanges meaning of z and y for commands): >
-	    :set langmap=zy,yz,ZY,YZ
-<
-	The 'langmap' option is a list of parts, separated with commas.  Each
-	part can be in one of two forms:
-	1.  A list of pairs.  Each pair is a "from" character immediately
-	    followed by the "to" character.  Examples: "aA", "aAbBcC".
-	2.  A list of "from" characters, a semi-colon and a list of "to"
-	    characters.  Example: "abc;ABC"
-	Example: "aA,fgh;FGH,cCdDeE"
-	Special characters need to be preceded with a backslash.  These are
-	";", ',', '"', '|' and backslash itself.
-
-	This will allow you to activate vim actions without having to switch
-	back and forth between the languages.  Your language characters will
-	be understood as normal vim English characters (according to the
-	langmap mappings) in the following cases:
-	 o Normal/Visual mode (commands, buffer/register names, user mappings)
-	 o Insert/Replace Mode: Register names after CTRL-R
-	 o Insert/Replace Mode: Mappings
-	Characters entered in Command-line mode will NOT be affected by
-	this option.   Note that this option can be changed at any time
-	allowing to switch between mappings for different languages/encodings.
-	Use a mapping to avoid having to type it each time!
-
-					*'langmenu'* *'lm'*
-'langmenu' 'lm'		string	(default "")
-			global
-			{only available when compiled with the |+menu| and
-			|+multi_lang| features}
-	Language to use for menu translation.  Tells which file is loaded
-	from the "lang" directory in 'runtimepath': >
-		"lang/menu_" .. &langmenu .. ".vim"
-<	(without the spaces).  For example, to always use the Dutch menus, no
-	matter what $LANG is set to: >
-		:set langmenu=nl_NL.ISO_8859-1
-<	When 'langmenu' is empty, |v:lang| is used.
-	Only normal file name characters can be used, "/\*?[|<>" are illegal.
-	If your $LANG is set to a non-English language but you do want to use
-	the English menus: >
-		:set langmenu=none
-<	This option must be set before loading menus, switching on filetype
-	detection or syntax highlighting.  Once the menus are defined setting
-	this option has no effect.  But you could do this: >
-		:source $VIMRUNTIME/delmenu.vim
-		:set langmenu=de_DE.ISO_8859-1
-		:source $VIMRUNTIME/menu.vim
-<	Warning: This deletes all menus that you defined yourself!
-
-			*'langnoremap'* *'lnr'* *'nolangnoremap'* *'nolnr'*
-'langnoremap' 'lnr'	boolean (default off, set in |defaults.vim|)
-			global
-			{only available when compiled with the |+langmap|
-			feature}
-	This is just like 'langremap' but with the value inverted.  It only
-	exists for backwards compatibility.  When setting 'langremap' then
-	'langnoremap' is set to the inverted value, and the other way around.
-
-			*'langremap'* *'lrm'* *'nolangremap'* *'nolrm'*
-'langremap' 'lrm'	boolean (default on, set to off in |defaults.vim|)
-			global
-			{only available when compiled with the |+langmap|
-			feature}
-	When off, setting 'langmap' does not apply to characters resulting from
-	a mapping.  This basically means, if you noticed that setting
-	'langmap' disables some of your mappings, try resetting this option.
-	This option defaults to on for backwards compatibility.  Set it off if
-	that works for you to avoid mappings to break.
-
-					*'laststatus'* *'ls'*
-'laststatus' 'ls'	number	(default 1)
-			global
-	The value of this option influences when the last window will have a
-	status line:
-		0: never
-		1: only if there are at least two windows
-		2: always
-	The screen looks nicer with a status line if you have several
-	windows, but it takes another screen line. |status-line|
-
-			*'lazyredraw'* *'lz'* *'nolazyredraw'* *'nolz'*
-'lazyredraw' 'lz'	boolean	(default off)
-			global
-	When this option is set, the screen will not be redrawn while
-	executing macros, registers and other commands that have not been
-	typed.  Also, updating the window title is postponed.  To force an
-	update use |:redraw|.
-	This may occasionally cause display errors.  It is only meant to be set
-	temporarily when performing an operation where redrawing may cause
-	flickering or cause a slow down.
-
-			*'linebreak'* *'lbr'* *'nolinebreak'* *'nolbr'*
-'linebreak' 'lbr'	boolean	(default off)
-			local to window
-			{not available when compiled without the |+linebreak|
-			feature}
-	If on, Vim will wrap long lines at a character in 'breakat' rather
-	than at the last character that fits on the screen.  Unlike
-	'wrapmargin' and 'textwidth', this does not insert <EOL>s in the file,
-	it only affects the way the file is displayed, not its contents.
-	If 'breakindent' is set, line is visually indented. Then, the value
-	of 'showbreak' is used to put in front of wrapped lines. This option
-	is not used when the 'wrap' option is off.
-	Note that <Tab> characters after an <EOL> are mostly not displayed
-	with the right amount of white space.
-
-						*'lines'* *E593*
-'lines'			number	(default 24 or terminal height)
-			global
-	Number of lines of the Vim window.
-	Normally you don't need to set this.  It is done automatically by the
-	terminal initialization code.  Also see |posix-screen-size|.
-	When Vim is running in the GUI or in a resizable window, setting this
-	option will cause the window size to be changed.  When you only want
-	to use the size for the GUI, put the command in your |gvimrc| file.
-	Vim limits the number of lines to what fits on the screen.  You can
-	use this command to get the tallest window possible: >
-		:set lines=999
-<	Minimum value is 2, maximum value is 1000.
-	If you get fewer lines than expected, check the 'guiheadroom' option.
-	When you set this option and Vim is unable to change the physical
-	number of lines of the display, the display may be messed up.
-
-						*'linespace'* *'lsp'*
-'linespace' 'lsp'	number	(default 0, 1 for Win32 GUI)
-			global
-			{only in the GUI}
-	Number of pixel lines inserted between characters.  Useful if the font
-	uses the full character cell height, making lines touch each other.
-	When non-zero there is room for underlining.
-	With some fonts there can be too much room between lines (to have
-	space for ascents and descents).  Then it makes sense to set
-	'linespace' to a negative value.  This may cause display problems
-	though!
-
-						*'lisp'* *'nolisp'*
-'lisp'			boolean	(default off)
-			local to buffer
-	Lisp mode: When <Enter> is typed in insert mode set the indent for
-	the next line to Lisp standards (well, sort of).  Also happens with
-	"cc" or "S".  'autoindent' must also be on for this to work.  The 'p'
-	flag in 'cpoptions' changes the method of indenting: Vi compatible or
-	better.  Also see 'lispwords'.
-	The '-' character is included in keyword characters.  Redefines the
-	"=" operator to use this same indentation algorithm rather than
-	calling an external program if 'equalprg' is empty.
-	This option is not used when 'paste' is set.
-
-						*'lispoptions'* *'lop'*
-'lispoptions' 'lop'	string	(default "")
-			local to buffer
-	Comma-separated list of items that influence the Lisp indenting when
-	enabled with the |'lisp'| option.  Currently only one item is
-	supported:
-		expr:1	use 'indentexpr' for Lisp indenting when it is set
-		expr:0	do not use 'indentexpr' for Lisp indenting (default)
-	Note that when using 'indentexpr' the `=` operator indents all the
-	lines, otherwise the first line is not indented (Vi-compatible).
-
-						*'lispwords'* *'lw'*
-'lispwords' 'lw'	string	(default is very long)
-			global or local to buffer |global-local|
-	Comma-separated list of words that influence the Lisp indenting when
-	enabled with the |'lisp'| option.
-
-						*'list'* *'nolist'*
-'list'			boolean	(default off)
-			local to window
-	List mode: By default show tabs as CTRL-I is displayed, display $
-	after end of line.  Useful to see the difference between tabs and
-	spaces and for trailing blanks.  Further changed by the 'listchars'
-	option.
-
-	The cursor is displayed at the start of the space a Tab character
-	occupies, not at the end as usual in Normal mode.  To get this cursor
-	position while displaying Tabs with spaces, use: >
-		:set list lcs=tab:\ \ 
-<
-	Note that list mode will also affect formatting (set with 'textwidth'
-	or 'wrapmargin') when 'cpoptions' includes 'L'.  See 'listchars' for
-	changing the way tabs are displayed.
-
-						*'listchars'* *'lcs'*
-'listchars' 'lcs'	string	(default "eol:$")
-			global or local to window |global-local|
-	Strings to use in 'list' mode and for the |:list| command.  It is a
-	comma-separated list of string settings.
-							*lcs-eol*
-	  eol:c		Character to show at the end of each line.  When
-			omitted, there is no extra character at the end of the
-			line.
-							*lcs-tab*
-	  tab:xy[z]	Two or three characters to be used to show a tab.
-			The third character is optional.
-
-	  tab:xy	The 'x' is always used, then 'y' as many times as will
-			fit.  Thus "tab:>-" displays:
-				>
-				>-
-				>--
-				etc.
-
-	  tab:xyz	The 'z' is always used, then 'x' is prepended, and
-			then 'y' is used as many times as will fit.  Thus
-			"tab:<->" displays:
-				>
-				<>
-				<->
-				<-->
-				etc.
-
-			When "tab:" is omitted, a tab is shown as ^I.
-							*lcs-space*
-	  space:c	Character to show for a space.  When omitted, spaces
-			are left blank.
-							*lcs-multispace*
-	  multispace:c...
-			One or more characters to use cyclically to show for
-			multiple consecutive spaces.  Overrides the "space"
-			setting, except for single spaces.  When omitted, the
-			"space" setting is used.  For example,
-			`:set listchars=multispace:---+` shows ten consecutive
-			spaces as:
-				---+---+-- ~
-							*lcs-lead*
-	  lead:c	Character to show for leading spaces.  When omitted,
-			leading spaces are blank.  Overrides the "space" and
-			"multispace" settings for leading spaces.  You can
-			combine it with "tab:", for example: >
-				:set listchars+=tab:>-,lead:.
-<							*lcs-leadmultispace*
-	  leadmultispace:c...
-			Like the |lcs-multispace| value, but for leading
-			spaces only.  Also overrides |lcs-lead| for leading
-			multiple spaces.
-			`:set listchars=leadmultispace:---+` shows ten
-			consecutive leading spaces as:
-				---+---+--XXX ~
-			Where "XXX" denotes the first non-blank characters in
-			the line.
-							*lcs-trail*
-	  trail:c	Character to show for trailing spaces.  When omitted,
-			trailing spaces are blank.  Overrides the "space" and
-			"multispace" settings for trailing spaces.
-							*lcs-extends*
-	  extends:c	Character to show in the last column, when 'wrap' is
-			off and the line continues beyond the right of the
-			screen.
-							*lcs-precedes*
-	  precedes:c	Character to show in the first visible column of the
-			physical line, when there is text preceding the
-			character visible in the first column.
-							*lcs-conceal*
-	  conceal:c	Character to show in place of concealed text, when
-			'conceallevel' is set to 1.
-							*lcs-nbsp*
-	  nbsp:c	Character to show for a non-breakable space character
-			(0xA0 (160 decimal) and U+202F).  Left blank when
-			omitted.
-
-	The characters ':' and ',' should not be used.  UTF-8 characters can
-	be used when 'encoding' is "utf-8", otherwise only printable
-	characters are allowed.  All characters must be single width.
-
-	Each character can be specified as hex: >
-		set listchars=eol:\\x24
-		set listchars=eol:\\u21b5
-		set listchars=eol:\\U000021b5
-<	Note that a double backslash is used.  The number of hex characters
-	must be exactly 2 for \\x, 4 for \\u and 8 for \\U.
-
-	Examples: >
-	    :set lcs=tab:>-,trail:-
-	    :set lcs=tab:>-,eol:<,nbsp:%
-	    :set lcs=extends:>,precedes:<
-<	The "NonText" highlighting will be used for "eol", "extends" and
-	"precedes".  "SpecialKey" will be used for "tab", "nbsp", "space",
-	"multispace", "lead" and "trail".
-	|hl-NonText| |hl-SpecialKey|
-
-			*'lpl'* *'nolpl'* *'loadplugins'* *'noloadplugins'*
-'loadplugins' 'lpl'	boolean	(default on)
-			global
-	When on the plugin scripts are loaded when starting up |load-plugins|.
-	This option can be reset in your |vimrc| file to disable the loading
-	of plugins.
-	Note that using the "-u NONE", "-u DEFAULTS" and "--noplugin" command
-	line arguments reset this option.  See |-u| and |--noplugin|.
-
-						*'luadll'*
-'luadll'		string	(default depends on the build)
-			global
-			{only available when compiled with the |+lua/dyn|
-			feature}
-	Specifies the name of the Lua shared library. The default is
-	DYNAMIC_LUA_DLL, which was specified at compile time.
-	Environment variables are expanded |:set_env|.
-	This option cannot be set from a |modeline| or in the |sandbox|, for
-	security reasons.
-
-						*'macatsui'* *'nomacatsui'*
-'macatsui'		boolean	(default on)
-			global
-			{not supported}
-	No longer supported, as the Mac OS X GUI code was removed.
-
-						*'magic'* *'nomagic'*
-'magic'			boolean	(default on)
-			global
-	Changes the special characters that can be used in search patterns.
-	See |pattern|.
-	WARNING: Switching this option off most likely breaks plugins!  That
-	is because many patterns assume it's on and will fail when it's off.
-	Only switch it off when working with old Vi scripts.  In any other
-	situation write patterns that work when 'magic' is on.  Include "\M"
-	when you want to |/\M|.
-	In |Vim9| script the value of 'magic' is ignored, patterns behave like
-	it is always set.
-
-						*'makeef'* *'mef'*
-'makeef' 'mef'		string	(default: "")
-			global
-			{not available when compiled without the |+quickfix|
-			feature}
-	Name of the errorfile for the |:make| command (see |:make_makeprg|)
-	and the |:grep| command.
-	When it is empty, an internally generated temp file will be used.
-	When "##" is included, it is replaced by a number to make the name
-	unique.  This makes sure that the ":make" command doesn't overwrite an
-	existing file.
-	NOT used for the ":cf" command.  See 'errorfile' for that.
-	Environment variables are expanded |:set_env|.
-	See |option-backslash| about including spaces and backslashes.
-	This option cannot be set from a |modeline| or in the |sandbox|, for
-	security reasons.
-
-					*'makeencoding'* *'menc'*
-'makeencoding' 'menc'	string	(default "")
-			global or local to buffer |global-local|
-	Encoding used for reading the output of external commands.  When empty,
-	encoding is not converted.
-	This is used for `:make`, `:lmake`, `:grep`, `:lgrep`, `:grepadd`,
-	`:lgrepadd`, `:cfile`, `:cgetfile`, `:caddfile`, `:lfile`, `:lgetfile`,
-	and `:laddfile`.
-
-	This would be mostly useful when you use MS-Windows and set 'encoding'
-	to "utf-8".  If |+iconv| is enabled and GNU libiconv is used, setting
-	'makeencoding' to "char" has the same effect as setting to the system
-	locale encoding.  Example: >
-		:set encoding=utf-8
-		:set makeencoding=char	" system locale is used
-<
-						*'makeprg'* *'mp'*
-'makeprg' 'mp'		string	(default "make", VMS: "MMS")
-			global or local to buffer |global-local|
-	Program to use for the ":make" command.  See |:make_makeprg|.
-	This option may contain '%' and '#' characters (see  |:_%| and |:_#|),
-	which are expanded to the current and alternate file name.  Use |::S|
-	to escape file names in case they contain special characters.
-	Environment variables are expanded |:set_env|.  See |option-backslash|
-	about including spaces and backslashes.
-	Note that a '|' must be escaped twice: once for ":set" and once for
-	the interpretation of a command.  When you use a filter called
-	"myfilter" do it like this: >
-	    :set makeprg=gmake\ \\\|\ myfilter
-<	The placeholder "$*" can be given (even multiple times) to specify
-	where the arguments will be included, for example: >
-	    :set makeprg=latex\ \\\\nonstopmode\ \\\\input\\{$*}
-<	This option cannot be set from a |modeline| or in the |sandbox|, for
-	security reasons.
-
-						*'matchpairs'* *'mps'*
-'matchpairs' 'mps'	string	(default "(:),{:},[:]")
-			local to buffer
-	Characters that form pairs.  The |%| command jumps from one to the
-	other.
-	Only character pairs are allowed that are different, thus you cannot
-	jump between two double quotes.
-	The characters must be separated by a colon.
-	The pairs must be separated by a comma.  Example for including '<' and
-	'>' (for HTML): >
-		:set mps+=<:>
-
-<	A more exotic example, to jump between the '=' and ';' in an
-	assignment, useful for languages like C and Java: >
-		:au FileType c,cpp,java set mps+==:;
-
-<	For a more advanced way of using "%", see the matchit.vim plugin in
-	the $VIMRUNTIME/pack/dist/opt/matchit directory. |add-local-help|
-
-						*'matchtime'* *'mat'*
-'matchtime' 'mat'	number	(default 5)
-			global
-	Tenths of a second to show the matching paren, when 'showmatch' is
-	set.  Note that this is not in milliseconds, like other options that
-	set a time.  This is to be compatible with Nvi.
-
-						*'maxcombine'* *'mco'*
-'maxcombine' 'mco'	number (default 2)
-			global
-	The maximum number of combining characters supported for displaying.
-	Only used when 'encoding' is "utf-8".
-	The default is OK for most languages.  Hebrew may require 4.
-	Maximum value is 6.
-	Even when this option is set to 2 you can still edit text with more
-	combining characters, you just can't see them.  Use |g8| or |ga|.
-	See |mbyte-combining|.
-
-						*'maxfuncdepth'* *'mfd'*
-'maxfuncdepth' 'mfd'	number	(default 100)
-			global
-			{not available when compiled without the |+eval|
-			feature}
-	Maximum depth of function calls for user functions.  This normally
-	catches endless recursion.  When using a recursive function with
-	more depth, set 'maxfuncdepth' to a bigger number.  But this will use
-	more memory, there is the danger of failing when memory is exhausted.
-	Increasing this limit above 200 also changes the maximum for Ex
-	command recursion, see |E169|.
-	See also |:function|.
-
-						*'maxmapdepth'* *'mmd'* *E223*
-'maxmapdepth' 'mmd'	number	(default 1000)
-			global
-	Maximum number of times a mapping is done without resulting in a
-	character to be used.  This normally catches endless mappings, like
-	":map x y" with ":map y x".  It still does not catch ":map g wg",
-	because the 'w' is used before the next mapping is done.  See also
-	|key-mapping|.
-
-						*'maxmem'* *'mm'*
-'maxmem' 'mm'		number	(default between 256 to 5120 (system
-				 dependent) or half the amount of memory
-				 available)
-			global
-	Maximum amount of memory (in Kbyte) to use for one buffer.  When this
-	limit is reached allocating extra memory for a buffer will cause
-	other memory to be freed.
-	The maximum usable value is about 2000000.  Use this to work without a
-	limit.
-	The value is ignored when 'swapfile' is off.
-	Also see 'maxmemtot'.
-
-						*'maxmempattern'* *'mmp'*
-'maxmempattern' 'mmp'	number	(default 1000)
-			global
-	Maximum amount of memory (in Kbyte) to use for pattern matching.
-	The maximum value is about 2000000.  Use this to work without a limit.
-							*E363*
-	When Vim runs into the limit it gives an error message and mostly
-	behaves like CTRL-C was typed.
-	Running into the limit often means that the pattern is very
-	inefficient or too complex.  This may already happen with the pattern
-	"\(.\)*" on a very long line.  ".*" works much better.
-	Might also happen on redraw, when syntax rules try to match a complex
-	text structure.
-	Vim may run out of memory before hitting the 'maxmempattern' limit, in
-	which case you get an "Out of memory" error instead.
-
-						*'maxmemtot'* *'mmt'*
-'maxmemtot' 'mmt'	number	(default between 2048 and 10240 (system
-				 dependent) or half the amount of memory
-				 available)
-			global
-	Maximum amount of memory in Kbyte to use for all buffers together.
-	The maximum usable value is about 2000000 (2 Gbyte).  Use this to work
-	without a limit.
-	On 64 bit machines higher values might work.  But hey, do you really
-	need more than 2 Gbyte for text editing?  Keep in mind that text is
-	stored in the swap file, one can edit files > 2 Gbyte anyway.  We do
-	need the memory to store undo info.
-	Buffers with 'swapfile' off still count to the total amount of memory
-	used.
-	Also see 'maxmem'.
-
-						*'menuitems'* *'mis'*
-'menuitems' 'mis'	number	(default 25)
-			global
-			{not available when compiled without the |+menu|
-			feature}
-	Maximum number of items to use in a menu.  Used for menus that are
-	generated from a list of items, e.g., the Buffers menu.  Changing this
-	option has no direct effect, the menu must be refreshed first.
-
-						*'mkspellmem'* *'msm'*
-'mkspellmem' 'msm'	string	(default "460000,2000,500")
-			global
-			{not available when compiled without the |+syntax|
-			feature}
-	Parameters for |:mkspell|.  This tunes when to start compressing the
-	word tree.  Compression can be slow when there are many words, but
-	it's needed to avoid running out of memory.  The amount of memory used
-	per word depends very much on how similar the words are, that's why
-	this tuning is complicated.
-
-	There are three numbers, separated by commas:
-		{start},{inc},{added}
-
-	For most languages the uncompressed word tree fits in memory.  {start}
-	gives the amount of memory in Kbyte that can be used before any
-	compression is done.  It should be a bit smaller than the amount of
-	memory that is available to Vim.
-
-	When going over the {start} limit the {inc} number specifies the
-	amount of memory in Kbyte that can be allocated before another
-	compression is done.  A low number means compression is done after
-	less words are added, which is slow.  A high number means more memory
-	will be allocated.
-
-	After doing compression, {added} times 1024 words can be added before
-	the {inc} limit is ignored and compression is done when any extra
-	amount of memory is needed.  A low number means there is a smaller
-	chance of hitting the {inc} limit, less memory is used but it's
-	slower.
-
-	The languages for which these numbers are important are Italian and
-	Hungarian.  The default works for when you have about 512 Mbyte.  If
-	you have 1 Gbyte you could use: >
-		:set mkspellmem=900000,3000,800
-<	If you have less than 512 Mbyte |:mkspell| may fail for some
-	languages, no matter what you set 'mkspellmem' to.
-
-	This option cannot be set from a |modeline| or in the |sandbox|.

-				   *'modeline'* *'ml'* *'nomodeline'* *'noml'*
-'modeline' 'ml'		boolean	(Vim default: on (off for root),
-				 Vi default: off)
-			local to buffer
-	If 'modeline' is on 'modelines' gives the number of lines that is
-	checked for set commands.  If 'modeline' is off or 'modelines' is zero
-	no lines are checked.  See |modeline|.
-
-			   *'modelineexpr'* *'mle'* *'nomodelineexpr'* *'nomle'*
-'modelineexpr' 'mle'	boolean (default: off)
-			global
-	When on allow some options that are an expression to be set in the
-	modeline.  Check the option for whether it is affected by
-	'modelineexpr'.  Also see |modeline|.
-	This option cannot be set from a |modeline| or in the |sandbox|, for
-	security reasons.
-
-						*'modelines'* *'mls'*
-'modelines' 'mls'	number	(default 5)
-			global
-	If 'modeline' is on 'modelines' gives the number of lines that is
-	checked for set commands.  If 'modeline' is off or 'modelines' is zero
-	no lines are checked.  See |modeline|.
-	NOTE: 'modeline' is set to the Vi default value when 'compatible' is
-	set and to the Vim default value when 'compatible' is reset.
-
-				*'modifiable'* *'ma'* *'nomodifiable'* *'noma'*
-				*E21*
-'modifiable' 'ma'	boolean	(default on)
-			local to buffer
-	When off the buffer contents cannot be changed.  The 'fileformat' and
-	'fileencoding' options also can't be changed.
-	Can be reset on startup with the |-M| command line argument.
-
-				*'modified'* *'mod'* *'nomodified'* *'nomod'*
-'modified' 'mod'	boolean	(default off)
-			local to buffer
-	When on, the buffer is considered to be modified.  This option is set
-	when:
-	1. A change was made to the text since it was last written.  Using the
-	   |undo| command to go back to the original text will reset the
-	   option.  But undoing changes that were made before writing the
-	   buffer will set the option again, since the text is different from
-	   when it was written.
-	2. 'fileformat' or 'fileencoding' is different from its original
-	   value.  The original value is set when the buffer is read or
-	   written.  A ":set nomodified" command also resets the original
-	   values to the current values and the 'modified' option will be
-	   reset.
-	   Similarly for 'eol' and 'bomb'.
-	This option is not set when a change is made to the buffer as the
-	result of a BufNewFile, BufRead/BufReadPost, BufWritePost,
-	FileAppendPost or VimLeave autocommand event.  See |gzip-example| for
-	an explanation.
-	When 'buftype' is "nowrite" or "nofile" this option may be set, but
-	will be ignored.
-	Note that the text may actually be the same, e.g. 'modified' is set
-	when using "rA" on an "A".
-
-						*'more'* *'nomore'*
-'more'			boolean	(Vim default: on, Vi default: off)
-			global
-	When on, listings pause when the whole screen is filled.  You will get
-	the |more-prompt|.  When this option is off there are no pauses, the
-	listing continues until finished.
-	NOTE: This option is set to the Vi default value when 'compatible' is
-	set and to the Vim default value when 'compatible' is reset.
-
-						*'mouse'*
-'mouse'			string	(default "", "a" for GUI and Win32,
-					set to "a" or "nvi" in |defaults.vim|)
-			global
-	Enable the use of the mouse.  Works for most terminals (xterm, Win32
-	|win32-mouse|, QNX pterm, *BSD console with sysmouse and Linux console
-	with gpm).  For using the mouse in the GUI, see |gui-mouse|.  The
-	mouse can be enabled for different modes:
-		n	Normal mode and Terminal modes
-		v	Visual mode
-		i	Insert mode
-		c	Command-line mode
-		h	all previous modes when editing a help file
-		a	all previous modes
-		r	for |hit-enter| and |more-prompt| prompt
-	Normally you would enable the mouse in all five modes with: >
-		:set mouse=a
-<	If your terminal can't overrule the mouse events going to the
-	application, use: >
-		:set mouse=nvi
-<	Then you can press ":", select text for the system, and press Esc to go
-	back to Vim using the mouse events.
-	In |defaults.vim| "nvi" is used if the 'term' option is not matching
-	"xterm".
-
-	When the mouse is not enabled, the GUI will still use the mouse for
-	modeless selection.  This doesn't move the text cursor.
-
-	See |mouse-using|.  Also see |'clipboard'|.
-
-	Note: When enabling the mouse in a terminal, copy/paste will use the
-	"* register if there is access to an X-server.  The xterm handling of
-	the mouse buttons can still be used by keeping the shift key pressed.
-	Also see the 'clipboard' option.
-
-			*'mousefocus'* *'mousef'* *'nomousefocus'* *'nomousef'*
-'mousefocus' 'mousef'	boolean	(default off)
-			global
-			{only works in the GUI}
-	The window that the mouse pointer is on is automatically activated.
-	When changing the window layout or window focus in another way, the
-	mouse pointer is moved to the window with keyboard focus.  Off is the
-	default because it makes using the pull down menus a little goofy, as
-	a pointer transit may activate a window unintentionally.
-	MS-Windows: Also see 'scrollfocus' for what window is scrolled when
-	using the mouse scroll wheel.
-
-			*'mousehide'* *'mh'* *'nomousehide'* *'nomh'*
-'mousehide' 'mh'	boolean	(default on)
-			global
-			{only works in the GUI}
-	When on, the mouse pointer is hidden when characters are typed.
-	The mouse pointer is restored when the mouse is moved.
-
-						*'mousemodel'* *'mousem'*
-'mousemodel' 'mousem'	string	(default "extend", "popup" for Win32)
-			global
-	Sets the model to use for the mouse.  The name mostly specifies what
-	the right mouse button is used for:
-	   extend	Right mouse button extends a selection.  This works
-			like in an xterm.
-	   popup	Right mouse button pops up a menu.  The shifted left
-			mouse button extends a selection.  This works like
-			with Microsoft Windows.
-	   popup_setpos Like "popup", but the cursor will be moved to the
-			position where the mouse was clicked, and thus the
-			selected operation will act upon the clicked object.
-			If clicking inside a selection, that selection will
-			be acted upon, i.e. no cursor move.  This implies of
-			course, that right clicking outside a selection will
-			end Visual mode.
-	Overview of what button does what for each model:
-	mouse		    extend		popup(_setpos) ~
-	left click	    place cursor	place cursor
-	left drag	    start selection	start selection
-	shift-left	    search word		extend selection
-	right click	    extend selection	popup menu (place cursor)
-	right drag	    extend selection	-
-	middle click	    paste		paste
-
-	In the "popup" model the right mouse button produces a pop-up menu.
-	You need to define this first, see |popup-menu|.
-
-	Note that you can further refine the meaning of buttons with mappings.
-	See |gui-mouse-mapping|.  But mappings are NOT used for modeless
-	selection (because that's handled in the GUI code directly).
-
-	The 'mousemodel' option is set by the |:behave| command.
-
-	      *'mousemoveevent'* *'mousemev'* *'nomousemoveevent'* *'nomousemev'*
-'mousemoveevent' 'mousemev'  boolean	(default off)
-			global
-			{only works in the GUI}
-	When on, mouse move events are delivered to the input queue and are
-	available for mapping. The default, off, avoids the mouse movement
-	overhead except when needed. See |gui-mouse-mapping|.
-	Warning: Setting this option can make pending mappings to be aborted
-	when the mouse is moved.
-	Currently only works in the GUI, may be made to work in a terminal
-	later.
-
-					*'mouseshape'* *'mouses'* *E547*
-'mouseshape' 'mouses'	string	(default "i-r:beam,s:updown,sd:udsizing,
-					vs:leftright,vd:lrsizing,m:no,
-					ml:up-arrow,v:rightup-arrow")
-			global
-			{only available when compiled with the |+mouseshape|
-			feature}
-	This option tells Vim what the mouse pointer should look like in
-	different modes.  The option is a comma-separated list of parts, much
-	like used for 'guicursor'.  Each part consist of a mode/location-list
-	and an argument-list:
-		mode-list:shape,mode-list:shape,..
-	The mode-list is a dash separated list of these modes/locations:
-			In a normal window: ~
-		n	Normal mode
-		v	Visual mode
-		ve	Visual mode with 'selection' "exclusive" (same as 'v',
-			if not specified)
-		o	Operator-pending mode
-		i	Insert mode
-		r	Replace mode
-
-			Others: ~
-		c	appending to the command-line
-		ci	inserting in the command-line
-		cr	replacing in the command-line
-		m	at the 'Hit ENTER' or 'More' prompts
-		ml	idem, but cursor in the last line
-		e	any mode, pointer below last window
-		s	any mode, pointer on a status line
-		sd	any mode, while dragging a status line
-		vs	any mode, pointer on a vertical separator line
-		vd	any mode, while dragging a vertical separator line
-		a	everywhere
-
-	The shape is one of the following:
-	avail	name		looks like ~
-	w x	arrow		Normal mouse pointer
-	w x	blank		no pointer at all (use with care!)
-	w x	beam		I-beam
-	w x	updown		up-down sizing arrows
-	w x	leftright	left-right sizing arrows
-	w x	busy		The system's usual busy pointer
-	w x	no		The system's usual 'no input' pointer
-	  x	udsizing	indicates up-down resizing
-	  x	lrsizing	indicates left-right resizing
-	  x	crosshair	like a big thin +
-	  x	hand1		black hand
-	  x	hand2		white hand
-	  x	pencil		what you write with
-	  x	question	big ?
-	  x	rightup-arrow	arrow pointing right-up
-	w x	up-arrow	arrow pointing up
-	  x	<number>	any X11 pointer number (see X11/cursorfont.h)
-
-	The "avail" column contains a 'w' if the shape is available for Win32,
-	x for X11.
-	Any modes not specified or shapes not available use the normal mouse
-	pointer.
-
-	Example: >
-		:set mouseshape=s:udsizing,m:no
-<	will make the mouse turn to a sizing arrow over the status lines and
-	indicate no input when the hit-enter prompt is displayed (since
-	clicking the mouse has no effect in this state.)
-
-						*'mousetime'* *'mouset'*
-'mousetime' 'mouset'	number	(default 500)
-			global
-	Only for GUI, Win32 and Unix with xterm.  Defines the maximum
-	time in msec between two mouse clicks for the second click to be
-	recognized as a multi click.
-
-						*'mzschemedll'*
-'mzschemedll'		string	(default depends on the build)
-			global
-			{only available when compiled with the |+mzscheme/dyn|
-			feature}
-	Specifies the name of the MzScheme shared library. The default is
-	DYNAMIC_MZSCH_DLL which was specified at compile time.
-	Environment variables are expanded |:set_env|.
-	The value must be set in the |vimrc| script or earlier.  In the
-	startup, before the |load-plugins| step.
-	This option cannot be set from a |modeline| or in the |sandbox|, for
-	security reasons.
-
-						*'mzschemegcdll'*
-'mzschemegcdll'		string	(default depends on the build)
-			global
-			{only available when compiled with the |+mzscheme/dyn|
-			feature}
-	Specifies the name of the MzScheme GC shared library. The default is
-	DYNAMIC_MZGC_DLL which was specified at compile time.
-	The value can be equal to 'mzschemedll' if it includes the GC code.
-	Environment variables are expanded |:set_env|.
-	This option cannot be set from a |modeline| or in the |sandbox|, for
-	security reasons.
-
-						    *'mzquantum'* *'mzq'*
-'mzquantum' 'mzq'	number	(default 100)
-			global
-			{not available when compiled without the |+mzscheme|
-			feature}
-	The number of milliseconds between polls for MzScheme threads.
-	Negative or zero value means no thread scheduling.
-	NOTE: This option is set to the Vim default value when 'compatible'
-	is reset.
-
-							*'nrformats'* *'nf'*
-'nrformats' 'nf'	string	(default "bin,octal,hex",
-					   set to "bin,hex" in |defaults.vim|)
-			local to buffer
-	This defines what bases Vim will consider for numbers when using the
-	CTRL-A and CTRL-X commands for adding to and subtracting from a number
-	respectively; see |CTRL-A| for more info on these commands.
-	alpha	If included, single alphabetical characters will be
-		incremented or decremented.  This is useful for a list with a
-		letter index a), b), etc.		*octal-nrformats*
-	octal	If included, numbers that start with a zero will be considered
-		to be octal.  Example: Using CTRL-A on "007" results in "010".
-	hex	If included, numbers starting with "0x" or "0X" will be
-		considered to be hexadecimal.  Example: Using CTRL-X on
-		"0x100" results in "0x0ff".
-	bin	If included, numbers starting with "0b" or "0B" will be
-		considered to be binary.  Example: Using CTRL-X on
-		"0b1000" subtracts one, resulting in "0b0111".
-	unsigned    If included, numbers are recognized as unsigned. Thus a
-		leading dash or negative sign won't be considered as part of
-		the number.  Examples:
-		    Using CTRL-X on "2020" in "9-2020" results in "9-2019"
-		    (without "unsigned" it would become "9-2021").
-		    Using CTRL-A on "2020" in "9-2020" results in "9-2021"
-		    (without "unsigned" it would become "9-2019").
-		    Using CTRL-X on "0" or CTRL-A on "18446744073709551615"
-		    (2^64 - 1) has no effect, overflow is prevented.
-	Numbers which simply begin with a digit in the range 1-9 are always
-	considered decimal.  This also happens for numbers that are not
-	recognized as octal or hex.
-
-				*'number'* *'nu'* *'nonumber'* *'nonu'*
-'number' 'nu'		boolean	(default off)
-			local to window
-	Print the line number in front of each line.  When the 'n' option is
-	excluded from 'cpoptions' a wrapped line will not use the column of
-	line numbers (this is the default when 'compatible' isn't set).
-	The 'numberwidth' option can be used to set the room used for the line
-	number.
-	When a long, wrapped line doesn't start with the first character, '-'
-	characters are put before the number.
-	For highlighting see |hl-LineNr|, and |hl-CursorLineNr|, and the
-	|:sign-define| "numhl" argument.
-						*number_relativenumber*
-	The 'relativenumber' option changes the displayed number to be
-	relative to the cursor.  Together with 'number' there are these
-	four combinations (cursor in line 3):
-
-		'nonu'          'nu'            'nonu'          'nu'
-		'nornu'         'nornu'         'rnu'           'rnu'
-
-	    |apple          |  1 apple      |  2 apple      |  2 apple
-	    |pear           |  2 pear       |  1 pear       |  1 pear
-	    |nobody         |  3 nobody     |  0 nobody     |3   nobody
-	    |there          |  4 there      |  1 there      |  1 there
-
-						*'numberwidth'* *'nuw'*
-'numberwidth' 'nuw'	number	(Vim default: 4  Vi default: 8)
-			local to window
-			{only available when compiled with the |+linebreak|
-			feature}
-	Minimal number of columns to use for the line number.  Only relevant
-	when the 'number' or 'relativenumber' option is set or printing lines
-	with a line number. Since one space is always between the number and
-	the text, there is one less character for the number itself.
-	The value is the minimum width.  A bigger width is used when needed to
-	fit the highest line number in the buffer respectively the number of
-	rows in the window, depending on whether 'number' or 'relativenumber'
-	is set. Thus with the Vim default of 4 there is room for a line number
-	up to 999. When the buffer has 1000 lines five columns will be used.
-	The minimum value is 1, the maximum value is 20.
-	NOTE: This option is set to the Vi default value when 'compatible' is
-	set and to the Vim default value when 'compatible' is reset.
-
-						*'omnifunc'* *'ofu'*
-'omnifunc' 'ofu'	string	(default: empty)
-			local to buffer
-			{not available when compiled without the |+eval|
-			feature}
-	This option specifies a function to be used for Insert mode omni
-	completion with CTRL-X CTRL-O. |i_CTRL-X_CTRL-O|
-	See |complete-functions| for an explanation of how the function is
-	invoked and what it should return.  The value can be the name of a
-	function, a |lambda| or a |Funcref|. See |option-value-function| for
-	more information.
-	This option is usually set by a filetype plugin:
-	|:filetype-plugin-on|
-	This option cannot be set from a |modeline| or in the |sandbox|, for
-	security reasons.
-
-
-			    *'opendevice'* *'odev'* *'noopendevice'* *'noodev'*
-'opendevice' 'odev'	boolean	(default off)
-			global
-			{only for MS-Windows}  *E796*
-	Enable reading and writing from devices.  This may get Vim stuck on a
-	device that can be opened but doesn't actually do the I/O.  Therefore
-	it is off by default.
-	Note that on MS-Windows editing "aux.h", "lpt1.txt" and the like also
-	result in editing a device.
-
-
-						*'operatorfunc'* *'opfunc'*
-'operatorfunc' 'opfunc'	string	(default: empty)
-			global
-	This option specifies a function to be called by the |g@| operator.
-	See |:map-operator| for more info and an example.  The value can be
-	the name of a function, a |lambda| or a |Funcref|. See
-	|option-value-function| for more information.
-
-	This option cannot be set from a |modeline| or in the |sandbox|, for
-	security reasons.
-
-
-					*'osfiletype'* *'oft'*
-'osfiletype' 'oft'	string (default: "")
-			local to buffer
-	This option was supported on RISC OS, which has been removed.
-
-
-				*'packpath'* *'pp'*
-'packpath' 'pp'		string	(default: see 'runtimepath')
-	Directories used to find packages.  See |packages|.
-
-
-						*'paragraphs'* *'para'*
-'paragraphs' 'para'	string	(default "IPLPPPQPP TPHPLIPpLpItpplpipbp")
-			global
-	Specifies the nroff macros that separate paragraphs.  These are pairs
-	of two letters (see |object-motions|).
-
-						*'paste'* *'nopaste'*
-'paste'			boolean	(default off)
-			global
-	Put Vim in Paste mode.  This is useful if you want to cut or copy
-	some text from one window and paste it in Vim.  This will avoid
-	unexpected effects.
-	Setting this option is useful when using Vim in a terminal, where Vim
-	cannot distinguish between typed text and pasted text.  In the GUI, Vim
-	knows about pasting and will mostly do the right thing without 'paste'
-	being set.  The same is true for a terminal where Vim handles the
-	mouse clicks itself.
-	This option is reset when starting the GUI.  Thus if you set it in
-	your .vimrc it will work in a terminal, but not in the GUI.  Setting
-	'paste' in the GUI has side effects: e.g., the Paste toolbar button
-	will no longer work in Insert mode, because it uses a mapping.
-	When the 'paste' option is switched on (also when it was already on):
-		- mapping in Insert mode and Command-line mode is disabled
-		- abbreviations are disabled
-		- 'autoindent' is reset
-		- 'expandtab' is reset
-		- 'hkmap' is reset
-		- 'revins' is reset
-		- 'ruler' is reset
-		- 'showmatch' is reset
-		- 'smarttab' is reset
-		- 'softtabstop' is set to 0
-		- 'textwidth' is set to 0
-		- 'wrapmargin' is set to 0
-		- 'varsofttabstop' is made empty
-	These options keep their value, but their effect is disabled:
-		- 'cindent'
-		- 'formatoptions' is used like it is empty
-		- 'indentexpr'
-		- 'lisp'
-		- 'smartindent'
-	NOTE: When you start editing another file while the 'paste' option is
-	on, settings from the modelines or autocommands may change the
-	settings again, causing trouble when pasting text.  You might want to
-	set the 'paste' option again.
-	When the 'paste' option is reset the mentioned options are restored to
-	the value before the moment 'paste' was switched from off to on.
-	Resetting 'paste' before ever setting it does not have any effect.
-	Since mapping doesn't work while 'paste' is active, you need to use
-	the 'pastetoggle' option to toggle the 'paste' option with some key.
-
-						*'pastetoggle'* *'pt'*
-'pastetoggle' 'pt'	string	(default "")
-			global
-	When non-empty, specifies the key sequence that toggles the 'paste'
-	option.  This is like specifying a mapping: >
-	    :map {keys} :set invpaste<CR>
-<	Where {keys} is the value of 'pastetoggle'.
-	The difference is that it will work even when 'paste' is set.
-	'pastetoggle' works in Insert mode and Normal mode, but not in
-	Command-line mode.
-	Mappings are checked first, thus overrule 'pastetoggle'.  However,
-	when 'paste' is on mappings are ignored in Insert mode, thus you can do
-	this: >
-	    :map <F10> :set paste<CR>
-	    :map <F11> :set nopaste<CR>
-	    :imap <F10> <C-O>:set paste<CR>
-	    :imap <F11> <nop>
-	    :set pastetoggle=<F11>
-<	This will make <F10> start paste mode and <F11> stop paste mode.
-	Note that typing <F10> in paste mode inserts "<F10>", since in paste
-	mode everything is inserted literally, except the 'pastetoggle' key
-	sequence.

-
-					*'patchmode'* *'pm'* *E205* *E206*
-'patchmode' 'pm'	string	(default "")
-			global
-	When non-empty the oldest version of a file is kept.  This can be used
-	to keep the original version of a file if you are changing files in a
-	source distribution.  Only the first time that a file is written a
-	copy of the original file will be kept.  The name of the copy is the
-	name of the original file with the string in the 'patchmode' option
-	appended.  This option should start with a dot.  Use a string like
-	".orig" or ".org".  'backupdir' must not be empty for this to work
-	(Detail: The backup file is renamed to the patchmode file after the
-	new file has been successfully written, that's why it must be possible
-	to write a backup file).  If there was no file to be backed up, an
-	empty file is created.
-	When the 'backupskip' pattern matches, a patchmode file is not made.
-	Using 'patchmode' for compressed files appends the extension at the
-	end (e.g., "file.gz.orig"), thus the resulting name isn't always
-	recognized as a compressed file.
-	Only normal file name characters can be used, "/\*?[|<>" are illegal.

-				*'path'* *'pa'* *E343* *E345* *E347* *E854*
-'path' 'pa'		string	(default on Unix: ".,/usr/include,,"
-				   other systems: ".,,")
-			global or local to buffer |global-local|
-	This is a list of directories which will be searched when using the
-	|gf|, [f, ]f, ^Wf, |:find|, |:sfind|, |:tabfind| and other commands,
-	provided that the file being searched for has a relative path (not
-	starting with "/", "./" or "../").  The directories in the 'path'
-	option may be relative or absolute.
-	- Use commas to separate directory names: >
-		:set path=.,/usr/local/include,/usr/include
-<	- Spaces can also be used to separate directory names (for backwards
-	  compatibility with version 3.0).  To have a space in a directory
-	  name, precede it with an extra backslash, and escape the space: >
-		:set path=.,/dir/with\\\ space
-<	- To include a comma in a directory name precede it with an extra
-	  backslash: >
-		:set path=.,/dir/with\\,comma
-<	- To search relative to the directory of the current file, use: >
-		:set path=.
-<	- To search in the current directory use an empty string between two
-	  commas: >
-		:set path=,,
-<	- A directory name may end in a ':' or '/'.
-	- Environment variables are expanded |:set_env|.
-	- When using |netrw.vim| URLs can be used.  For example, adding
-	  "http://www.vim.org" will make ":find index.html" work.
-	- Search upwards and downwards in a directory tree using "*", "**" and
-	  ";".  See |file-searching| for info and syntax.
-	- Careful with '\' characters, type two to get one in the option: >
-		:set path=.,c:\\include
-<	  Or just use '/' instead: >
-		:set path=.,c:/include
-<	Don't forget "." or files won't even be found in the same directory as
-	the file!
-	The maximum length is limited.  How much depends on the system, mostly
-	it is something like 256 or 1024 characters.
-	You can check if all the include files are found, using the value of
-	'path', see |:checkpath|.
-	The use of |:set+=| and |:set-=| is preferred when adding or removing
-	directories from the list.  This avoids problems when a future version
-	uses another default.  To remove the current directory use: >
-		:set path-=
-<	To add the current directory use: >
-		:set path+=
-<	To use an environment variable, you probably need to replace the
-	separator.  Here is an example to append $INCL, in which directory
-	names are separated with a semi-colon: >
-		:let &path = &path .. "," .. substitute($INCL, ';', ',', 'g')
-<	Replace the ';' with a ':' or whatever separator is used.  Note that
-	this doesn't work when $INCL contains a comma or white space.

-'preserveindent' 'pi'	boolean	(default off)
-			local to buffer
-	When changing the indent of the current line, preserve as much of the
-	indent structure as possible.  Normally the indent is replaced by a
-	series of tabs followed by spaces as required (unless |'expandtab'| is
-	enabled, in which case only spaces are used).  Enabling this option
-	means the indent will preserve as many existing characters as possible
-	for indenting, and only add additional tabs or spaces as required.
-	'expandtab' does not apply to the preserved white space, a Tab remains
-	a Tab.
-	NOTE: When using ">>" multiple times the resulting indent is a mix of
-	tabs and spaces.  You might not like this.
-	NOTE: This option is reset when 'compatible' is set.
-	Also see 'copyindent'.
-	Use |:retab| to clean up white space.

-			feature}
-	The time in milliseconds for redrawing the display.  This applies to
-	searching for patterns for 'hlsearch', |:match| highlighting and syntax
-	highlighting.
-	When redrawing takes more than this many milliseconds no further
-	matches will be highlighted.
-	For syntax highlighting the time applies per window.  When over the

-
-						*'regexpengine'* *'re'*
-'regexpengine' 're'	number	(default 0)
-			global
-	This selects the default regexp engine. |two-engines|
-	The possible values are:
-		0	automatic selection
-		1	old engine
-		2	NFA engine
-	Note that when using the NFA engine and the pattern contains something
-	that is not supported the pattern will not match.  This is only useful
-	for debugging the regexp engine.
-	Using automatic selection enables Vim to switch the engine, if the
-	default engine becomes too costly.  E.g., when the NFA engine uses too
-	many states.  This should prevent Vim from hanging on a combination of
-	a complex pattern with long text.
-
-		*'relativenumber'* *'rnu'* *'norelativenumber'* *'nornu'*
-'relativenumber' 'rnu'	boolean	(default off)
-			local to window
-	Show the line number relative to the line with the cursor in front of
-	each line. Relative line numbers help you use the |count| you can
-	precede some vertical motion commands (e.g. j k + -) with, without
-	having to calculate it yourself. Especially useful in combination with
-	other commands (e.g. y d c < > gq gw =).
-	When the 'n' option is excluded from 'cpoptions' a wrapped
-	line will not use the column of line numbers (this is the default when
-	'compatible' isn't set).
-	The 'numberwidth' option can be used to set the room used for the line
-	number.
-	When a long, wrapped line doesn't start with the first character, '-'
-	characters are put before the number.
-	See |hl-LineNr|  and |hl-CursorLineNr| for the highlighting used for
-	the number.
-
-	The number in front of the cursor line also depends on the value of
-	'number', see |number_relativenumber| for all combinations of the two
-	options.
-
-						*'remap'* *'noremap'*
-'remap'			boolean	(default on)
-			global
-	Allows for mappings to work recursively.  If you do not want this for
-	a single entry, use the :noremap[!] command.
-	NOTE: To avoid portability problems with Vim scripts, always keep
-	this option at the default "on".  Only switch it off when working with
-	old Vi scripts.

-	screen.  If the statusline is given by 'statusline' (i.e. not empty),
-	this option takes precedence over 'ruler' and 'rulerformat'.
-	If the number of characters displayed is different from the number of
-	bytes in the text (e.g., for a TAB or a multibyte character), both
-	the text column (byte number) and the screen column are shown,
-	separated with a dash.
-	For an empty line "0-1" is shown.
-	For an empty buffer the line number will also be zero: "0,0-1".
-	This option is reset when 'paste' is set and restored when 'paste' is
-	reset.
-	If you don't want to see the ruler all the time but want to know where
-	you are, use "g CTRL-G" |g_CTRL-G|.
-	NOTE: This option is reset when 'compatible' is set.
-
-						*'rulerformat'* *'ruf'*
-'rulerformat' 'ruf'	string	(default empty)
-			global
-			{not available when compiled without the |+statusline|
-			feature}
-	When this option is not empty, it determines the content of the ruler
-	string, as displayed for the 'ruler' option.
-	The format of this option is like that of 'statusline'.
-	This option cannot be set in a modeline when 'modelineexpr' is off.
-
-	The default ruler width is 17 characters.  To make the ruler 15
-	characters wide, put "%15(" at the start and "%)" at the end.
-	Example: >
-		:set rulerformat=%15(%c%V\ %p%%%)

-	And any other file searched for with the |:runtime| command.
-
-	The defaults for most systems are setup to search five locations:
-	1. In your home directory, for your personal preferences.
-	2. In a system-wide Vim directory, for preferences from the system
-	   administrator.
-	3. In $VIMRUNTIME, for files distributed with Vim.
-							*after-directory*
-	4. In the "after" directory in the system-wide Vim directory.  This is
-	   for the system administrator to overrule or add to the distributed
-	   defaults (rarely needed)
-	5. In the "after" directory in your home directory.  This is for
-	   personal preferences to overrule or add to the distributed defaults
-	   or system-wide settings (rarely needed).
-
-	More entries are added when using |packages|.  If it gets very long
-	then `:set rtp` will be truncated, use `:echo &rtp` to see the full
-	string.
-
-	Note that, unlike 'path', no wildcards like "**" are allowed.  Normal
-	wildcards are allowed, but can significantly slow down searching for
-	runtime files.  For speed, use as few items as possible and avoid
-	wildcards.
-	See |:runtime|.
-	Example: >
-		:set runtimepath=~/vimruntime,/mygroup/vim,$VIMRUNTIME
-<	This will use the directory "~/vimruntime" first (containing your
-	personal Vim runtime files), then "/mygroup/vim" (shared between a
-	group of people) and finally "$VIMRUNTIME" (the distributed runtime
-	files).
-	You probably should always include $VIMRUNTIME somewhere, to use the
-	distributed runtime files.  You can put a directory before $VIMRUNTIME
-	to find files which replace a distributed runtime files.  You can put
-	a directory after $VIMRUNTIME to find files which add to distributed
-	runtime files.
-	When Vim is started with |--clean| the home directory entries are not
-	included.
-	This option cannot be set from a |modeline| or in the |sandbox|, for
-	security reasons.
-
-						*'scroll'* *'scr'*
-'scroll' 'scr'		number	(default: half the window height)
-			local to window
-	Number of lines to scroll with CTRL-U and CTRL-D commands.  Will be
-	set to half the number of lines in the window when the window size
-	changes.  This may happen when enabling the |status-line| or
-	'tabline' option after setting the 'scroll' option.
-	If you give a count to the CTRL-U or CTRL-D command it will
-	be used as the new value for 'scroll'.  Reset to half the window
-	height with ":set scroll=0".
-
-			*'scrollbind'* *'scb'* *'noscrollbind'* *'noscb'*
-'scrollbind' 'scb'	boolean  (default off)
-			local to window
-	See also |scroll-binding|.  When this option is set, the current
-	window scrolls as other scrollbind windows (windows that also have
-	this option set) scroll.  This option is useful for viewing the
-	differences between two versions of a file, see 'diff'.
-	See |'scrollopt'| for options that determine how this option should be
-	interpreted.
-	This option is mostly reset when splitting a window to edit another
-	file.  This means that ":split | edit file" results in two windows
-	with scroll-binding, but ":split file" does not.
-
-			*'scrollfocus'* *'scf'* *'noscrollfocus'* *'noscf'*
-'scrollfocus' 'scf'	boolean  (default off)
-			global
-			{only for MS-Windows GUI}
-	When using the scroll wheel and this option is set, the window under
-	the mouse pointer is scrolled.  With this option off the current
-	window is scrolled.
-	Systems other than MS-Windows always behave like this option is on.
-
-						*'scrolljump'* *'sj'*
-'scrolljump' 'sj'	number	(default 1)
-			global
-	Minimal number of lines to scroll when the cursor gets off the
-	screen (e.g., with "j").  Not used for scroll commands (e.g., CTRL-E,
-	CTRL-D).  Useful if your terminal scrolls very slowly.
-	When set to a negative number from -1 to -100 this is used as the
-	percentage of the window height.  Thus -50 scrolls half the window
-	height.
-	NOTE: This option is set to 1 when 'compatible' is set.
-
-						*'scrolloff'* *'so'*
-'scrolloff' 'so'	number	(default 0, set to 5 in |defaults.vim|)
-			global or local to window |global-local|
-	Minimal number of screen lines to keep above and below the cursor.
-	This will make some context visible around where you are working.  If
-	you set it to a very large value (999) the cursor line will always be
-	in the middle of the window (except at the start or end of the file or
-	when long lines wrap).
-	After using the local value, go back the global value with one of
-	these two: >
-		setlocal scrolloff<
-		setlocal scrolloff=-1
-<	For scrolling horizontally see 'sidescrolloff'.
-	NOTE: This option is set to 0 when 'compatible' is set.
-
-						*'scrollopt'* *'sbo'*
-'scrollopt' 'sbo'	string	(default "ver,jump")
-			global
-	This is a comma-separated list of words that specifies how
-	'scrollbind' windows should behave.  'sbo' stands for ScrollBind
-	Options.
-	The following words are available:
-	    ver		Bind vertical scrolling for 'scrollbind' windows
-	    hor		Bind horizontal scrolling for 'scrollbind' windows
-	    jump	Applies to the offset between two windows for vertical
-			scrolling.  This offset is the difference in the first
-			displayed line of the bound windows.  When moving
-			around in a window, another 'scrollbind' window may
-			reach a position before the start or after the end of
-			the buffer.  The offset is not changed though, when
-			moving back the 'scrollbind' window will try to scroll
-			to the desired position when possible.
-			When now making that window the current one, two
-			things can be done with the relative offset:
-			1. When "jump" is not included, the relative offset is
-			   adjusted for the scroll position in the new current
-			   window.  When going back to the other window, the
-			   new relative offset will be used.
-			2. When "jump" is included, the other windows are
-			   scrolled to keep the same relative offset.  When
-			   going back to the other window, it still uses the
-			   same relative offset.
-	Also see |scroll-binding|.
-	When 'diff' mode is active there always is vertical scroll binding,
-	even when "ver" isn't there.
-
-						*'sections'* *'sect'*
-'sections' 'sect'	string	(default "SHNHH HUnhsh")
-			global
-	Specifies the nroff macros that separate sections.  These are pairs of
-	two letters (See |object-motions|).  The default makes a section start
-	at the nroff macros ".SH", ".NH", ".H", ".HU", ".nh" and ".sh".
-
-						*'secure'* *'nosecure'* *E523*
-'secure'		boolean	(default off)
-			global
-	When on, ":autocmd", shell and write commands are not allowed in
-	".vimrc" and ".exrc" in the current directory and map commands are
-	displayed.  Switch it off only if you know that you will not run into
-	problems, or when the 'exrc' option is off.  On Unix this option is
-	only used if the ".vimrc" or ".exrc" is not owned by you.  This can be
-	dangerous if the systems allows users to do a "chown".  You better set
-	'secure' at the end of your ~/.vimrc then.
-	This option cannot be set from a |modeline| or in the |sandbox|, for
-	security reasons.
-
-						*'selection'* *'sel'*
-'selection' 'sel'	string	(default "inclusive")
-			global
-	This option defines the behavior of the selection.  It is only used
-	in Visual and Select mode.
-	Possible values:
-	   value	past line     inclusive ~
-	   old		   no		yes
-	   inclusive	   yes		yes
-	   exclusive	   yes		no
-	"past line" means that the cursor is allowed to be positioned one
-	character past the line.
-	"inclusive" means that the last character of the selection is included
-	in an operation.  For example, when "x" is used to delete the
-	selection.
-	When "old" is used and 'virtualedit' allows the cursor to move past
-	the end of line the line break still isn't included.
-	Note that when "exclusive" is used and selecting from the end
-	backwards, you cannot include the last character of a line, when
-	starting in Normal mode and 'virtualedit' empty.
-
-	The 'selection' option is set by the |:behave| command.
-
-						*'selectmode'* *'slm'*
-'selectmode' 'slm'	string	(default "")
-			global
-	This is a comma-separated list of words, which specifies when to start
-	Select mode instead of Visual mode, when a selection is started.
-	Possible values:
-	   mouse	when using the mouse
-	   key		when using shifted special keys
-	   cmd		when using "v", "V" or CTRL-V
-	See |Select-mode|.
-	The 'selectmode' option is set by the |:behave| command.
-
-						*'sessionoptions'* *'ssop'*
-'sessionoptions' 'ssop'	string	(default: "blank,buffers,curdir,folds,
-					 help,options,tabpages,winsize,terminal")
-			global
-			{not available when compiled without the |+mksession|
-			feature}
-	Changes the effect of the |:mksession| command.  It is a comma
-	separated list of words.  Each word enables saving and restoring
-	something:
-	   word		save and restore ~
-	   blank	empty windows
-	   buffers	hidden and unloaded buffers, not just those in windows
-	   curdir	the current directory
-	   folds	manually created folds, opened/closed folds and local
-			fold options
-	   globals	global variables that start with an uppercase letter
-			and contain at least one lowercase letter.  Only
-			String and Number types are stored.
-	   help		the help window
-	   localoptions	options and mappings local to a window or buffer (not
-			global values for local options)
-	   options	all options and mappings (also global values for local
-			options)
-	   skiprtp	exclude 'runtimepath' and 'packpath' from the options
-	   resize	size of the Vim window: 'lines' and 'columns'
-	   sesdir	the directory in which the session file is located
-			will become the current directory (useful with
-			projects accessed over a network from different
-			systems)
-	   slash	backslashes in file names replaced with forward
-			slashes
-	   tabpages	all tab pages; without this only the current tab page
-			is restored, so that you can make a session for each
-			tab page separately
-	   terminal	include terminal windows where the command can be
-			restored
-	   unix		with Unix end-of-line format (single <NL>), even when
-			on Windows or DOS
-	   winpos	position of the whole Vim window
-	   winsize	window sizes
-
-	Don't include both "curdir" and "sesdir".
-	When neither "curdir" nor "sesdir" is included, file names are stored
-	with absolute paths.
-	If you leave out "options" many things won't work well after restoring
-	the session.
-	"slash" and "unix" are useful on Windows when sharing session files
-	with Unix.  The Unix version of Vim cannot source dos format scripts,
-	but the Windows version of Vim can source unix format scripts.
-
-						*'shell'* *'sh'* *E91*
-'shell' 'sh'		string	(default $SHELL or "sh", Win32: "cmd.exe")
-			global
-	Name of the shell to use for ! and :! commands.  When changing the
-	value also check these options: 'shelltype', 'shellpipe', 'shellslash'
-	'shellredir', 'shellquote', 'shellxquote' and 'shellcmdflag'.
-	It is allowed to give an argument to the command, e.g.  "csh -f".
-	See |option-backslash| about including spaces and backslashes.
-	Environment variables are expanded |:set_env|.
-
-	In |restricted-mode| shell commands will not be possible.  This mode
-	is used if the value of $SHELL ends in "false" or "nologin".
-
-	If the name of the shell contains a space, you need to enclose it in
-	quotes and escape the space.  Example with quotes: >
-		:set shell=\"c:\program\ files\unix\sh.exe\"\ -f
-<	Note the backslash before each quote (to avoid starting a comment) and
-	each space (to avoid ending the option value).  Also note that the
-	"-f" is not inside the quotes, because it is not part of the command
-	name.  Vim automagically recognizes the backslashes that are path
-	separators.
-	Example with escaped space (Vim will do this when initializing the
-	option from $SHELL): >
-		:set shell=/bin/with\\\ space/sh
-<	The resulting value of 'shell' is "/bin/with\ space/sh", two
-	backslashes are consumed by `:set`.
-
-	Under MS-Windows, when the executable ends in ".com" it must be
-	included.  Thus setting the shell to "command.com" or "4dos.com"
-	works, but "command" and "4dos" do not work for all commands (e.g.,
-	filtering).
-	For unknown reasons, when using "4dos.com" the current directory is
-	changed to "C:\".  To avoid this set 'shell' like this: >
-		:set shell=command.com\ /c\ 4dos
-<	This option cannot be set from a |modeline| or in the |sandbox|, for
-	security reasons.
-
-						*'shellcmdflag'* *'shcf'*
-'shellcmdflag' 'shcf'	string	(default: "-c";
-				 Win32, when 'shell' contains "powershell":
-				 "-Command", or when it does not contain "sh"
-				 somewhere: "/c")
-			global
-	Flag passed to the shell to execute "!" and ":!" commands; e.g.,
-	"bash.exe -c ls", "powershell.exe -Command dir", or "cmd.exe /c dir".
-	For MS-Windows, the default is set according to the value of 'shell',
-	to reduce the need to set this option by the user.
-	On Unix it can have more than one flag.  Each white space separated
-	part is passed as an argument to the shell command.
-	See |option-backslash| about including spaces and backslashes.
-	Also see |dos-shell| and |dos-powershell| for MS-Windows.
-	This option cannot be set from a |modeline| or in the |sandbox|, for
-	security reasons.
-
-						*'shellpipe'* *'sp'*
-'shellpipe' 'sp'	string	(default ">", ">%s 2>&1", "| tee", "|& tee"
-				 "2>&1| tee", or
-				 "2>&1 | Out-File -Encoding default")
-			global
-			{not available when compiled without the |+quickfix|
-			feature}
-	String to be used to put the output of the ":make" command in the
-	error file.  See also |:make_makeprg|.  See |option-backslash| about
-	including spaces and backslashes.
-	The name of the temporary file can be represented by "%s" if necessary
-	(the file name is appended automatically if no %s appears in the value
-	of this option).
-	For the Amiga the default is ">".  For MS-Windows using powershell the
-	default is "2>&1 | Out-File -Encoding default", otherwise the default
-	is ">%s 2>&1".  The output is directly saved in a file and not echoed
-	to the screen.
-	For Unix the default is "| tee".  The stdout of the compiler is saved
-	in a file and echoed to the screen.  If the 'shell' option is "csh" or
-	"tcsh" after initializations, the default becomes "|& tee".  If the
-	'shell' option is "sh", "ksh", "mksh", "pdksh", "zsh", "zsh-beta",
-	"bash", "fish", "ash" or "dash" the default becomes "2>&1| tee".  This
-	means that stderr is also included.  Before using the 'shell' option a
-	path is removed, thus "/bin/sh" uses "sh".
-	For Unix and MS-Windows, when the 'shell' option is "pwsh" the default
-	becomes ">%s 2>&1" and the output is not echoed to the screen.
-	The initialization of this option is done after reading the ".vimrc"
-	and the other initializations, so that when the 'shell' option is set
-	there, the 'shellpipe' option changes automatically, unless it was
-	explicitly set before.
-	When 'shellpipe' is set to an empty string, no redirection of the
-	":make" output will be done.  This is useful if you use a 'makeprg'
-	that writes to 'makeef' by itself.  If you want no piping, but do
-	want to include the 'makeef', set 'shellpipe' to a single space.
-	Don't forget to precede the space with a backslash: ":set sp=\ ".
-	In the future pipes may be used for filtering and this option will
-	become obsolete (at least for Unix).
-	This option cannot be set from a |modeline| or in the |sandbox|, for
-	security reasons.
-
-						*'shellquote'* *'shq'*
-'shellquote' 'shq'	string	(default: "")
-			global
-	Quoting character(s), put around the command passed to the shell, for
-	the "!" and ":!" commands.  The redirection is kept outside of the
-	quoting.  See 'shellxquote' to include the redirection.  It's
-	probably not useful to set both options.
-	This is an empty string by default.  Only known to be useful for
-	third-party shells on MS-Windows-like systems, such as the MKS Korn
-	Shell or bash, where it should be "\"".  See |dos-shell|.
-	This option cannot be set from a |modeline| or in the |sandbox|, for
-	security reasons.
-
-						*'shellredir'* *'srr'*
-'shellredir' 'srr'	string	(default ">", ">&", ">%s 2>&1", or
-				 "2>&1 | Out-File -Encoding default")
-			global
-	String to be used to put the output of a filter command in a temporary
-	file.  See also |:!|.  See |option-backslash| about including spaces
-	and backslashes.
-	The name of the temporary file can be represented by "%s" if necessary
-	(the file name is appended automatically if no %s appears in the value
-	of this option).
-	The default is ">".  For Unix, if the 'shell' option is "csh" or
-	"tcsh" during initializations, the default becomes ">&".  If the
-	'shell' option is "sh", "ksh", "mksh", "pdksh", "zsh", "zsh-beta",
-	"bash", "fish", or "pwsh", the default becomes ">%s 2>&1".  This means
-	that stderr is also included.  For Win32, the Unix checks are done and
-	additionally "cmd" is checked for, which makes the default ">%s 2>&1",
-	and "powershell" is checked for which makes the default
-	"2>&1 | Out-File -Encoding default" (see |dos-powershell|).  Also, the
-	same names with ".exe" appended are checked for.
-	The initialization of this option is done after reading the ".vimrc"
-	and the other initializations, so that when the 'shell' option is set
-	there, the 'shellredir' option changes automatically unless it was
-	explicitly set before.
-	In the future pipes may be used for filtering and this option will
-	become obsolete (at least for Unix).
-	This option cannot be set from a |modeline| or in the |sandbox|, for
-	security reasons.
-
-			*'shellslash'* *'ssl'* *'noshellslash'* *'nossl'*
-'shellslash' 'ssl'	boolean	(default off)
-			global
-			{only for MS-Windows}
-	When set, a forward slash is used when expanding file names.  This is
-	useful when a Unix-like shell is used instead of cmd.exe, pwsh.exe, or
-	powershell.exe.  Backward slashes can still be typed, but they are
-	changed to forward slashes by Vim.
-	Note that setting or resetting this option has no effect for some
-	existing file names, thus this option needs to be set before opening
-	any file for best results.  This might change in the future.
-	'shellslash' only works when a backslash can be used as a path
-	separator.  To test if this is so use: >
-		if exists('+shellslash')
-<	Also see 'completeslash'.
-
-			*'shelltemp'* *'stmp'* *'noshelltemp'* *'nostmp'*
-'shelltemp' 'stmp'	boolean	(Vi default off, Vim default on)
-			global
-	When on, use temp files for shell commands.  When off use a pipe.
-	When using a pipe is not possible temp files are used anyway.
-	Currently a pipe is only supported on Unix and MS-Windows 2K and
-	later.  You can check it with: >
-		:if has("filterpipe")
-<	The advantage of using a pipe is that nobody can read the temp file
-	and the 'shell' command does not need to support redirection.
-	The advantage of using a temp file is that the file type and encoding
-	can be detected.
-	The |FilterReadPre|, |FilterReadPost| and |FilterWritePre|,
-	|FilterWritePost| autocommands event are not triggered when
-	'shelltemp' is off.
-	The `system()` function does not respect this option and always uses
-	temp files.
-	NOTE: This option is set to the Vim default value when 'compatible'
-	is reset.
-
-						*'shelltype'* *'st'*
-'shelltype' 'st'	number	(default 0)
-			global
-			{only for the Amiga}
-	On the Amiga this option influences the way how the commands work
-	which use a shell.
-	0 and 1: always use the shell
-	2 and 3: use the shell only to filter lines
-	4 and 5: use shell only for ':sh' command
-	When not using the shell, the command is executed directly.
-
-	0 and 2: use "shell 'shellcmdflag' cmd" to start external commands
-	1 and 3: use "shell cmd" to start external commands
-
-						*'shellxescape'* *'sxe'*
-'shellxescape' 'sxe'	string	(default: "";
-				 for MS-Windows: "\"&|<>()@^")
-			global
-	When 'shellxquote' is set to "(" then the characters listed in this
-	option will be escaped with a '^' character.  This makes it possible
-	to execute most external commands with cmd.exe.
-
-						*'shellxquote'* *'sxq'*
-'shellxquote' 'sxq'	string	(default: "";
-					for Win32, when 'shell' is cmd.exe: "("
-					for Win32, when 'shell' is
-					powershell.exe: "\""
-					for Win32, when 'shell' contains "sh"
-					somewhere: "\""
-					for Unix, when using system(): "\"")
-			global
-	Quoting character(s), put around the command passed to the shell, for
-	the "!" and ":!" commands.  Includes the redirection.  See
-	'shellquote' to exclude the redirection.  It's probably not useful
-	to set both options.
-	When the value is '(' then ')' is appended. When the value is '"('
-	then ')"' is appended.
-	When the value is '(' then also see 'shellxescape'.
-	This is an empty string by default on most systems, but is known to be
-	useful for on Win32 version, either for cmd.exe, powershell.exe, or
-	pwsh.exe which automatically strips off the first and last quote on a
-	command, or 3rd-party shells such as the MKS Korn Shell or bash, where
-	it should be "\"".  The default is adjusted according the value of
-	'shell', to reduce the need to set this option by the user.  See
-	|dos-shell|.
-	This option cannot be set from a |modeline| or in the |sandbox|, for
-	security reasons.
-
-			*'shiftround'* *'sr'* *'noshiftround'* *'nosr'*
-'shiftround' 'sr'	boolean	(default off)
-			global
-	Round indent to multiple of 'shiftwidth'.  Applies to > and <
-	commands.  CTRL-T and CTRL-D in Insert mode always round the indent to
-	a multiple of 'shiftwidth' (this is Vi compatible).
-	NOTE: This option is reset when 'compatible' is set.
-
-						*'shiftwidth'* *'sw'*
-'shiftwidth' 'sw'	number	(default 8)
-			local to buffer
-	Number of spaces to use for each step of (auto)indent.  Used for
-	|'cindent'|, |>>|, |<<|, etc.
-	When zero the 'tabstop' value will be used.  Use the |shiftwidth()|
-	function to get the effective shiftwidth value.
-
-						*'shortmess'* *'shm'*
-'shortmess' 'shm'	string	(Vim default "filnxtToOS", Vi default: "S",
-							POSIX default: "AS")
-			global					*E1336*
-	This option helps to avoid all the |hit-enter| prompts caused by file
-	messages, for example  with CTRL-G, and to avoid some other messages.
-	It is a list of flags:
-	 flag	meaning when present	~
-	  f	use "(3 of 5)" instead of "(file 3 of 5)"		*shm-f*
-	  i	use "[noeol]" instead of "[Incomplete last line]"	*shm-i*
-	  l	use "999L, 888B" instead of "999 lines, 888 bytes"	*shm-l*
-	  m	use "[+]" instead of "[Modified]"			*shm-m*
-	  n	use "[New]" instead of "[New File]"			*shm-n*
-	  r	use "[RO]" instead of "[readonly]"			*shm-r*
-	  w	use "[w]" instead of "written" for file write message	*shm-w*
-		and "[a]" instead of "appended" for ':w >> file' command
-	  x	use "[dos]" instead of "[dos format]", "[unix]"		*shm-x*
-		instead of "[unix format]" and "[mac]" instead of "[mac
-		format]"
-	  a	all of the above abbreviations				*shm-a*
-
-	  o	overwrite message for writing a file with subsequent	*shm-o*
-		message for reading a file (useful for ":wn" or when
-		'autowrite' on)
-	  O	message for reading a file overwrites any previous	*shm-O*
-		message;  also for quickfix message (e.g., ":cn")
-	  s	don't give "search hit BOTTOM, continuing at TOP" or	*shm-s*
-		"search hit TOP, continuing at BOTTOM" messages; when using
-		the search count do not show "W" after the count message (see
-		S below)
-	  t	truncate file message at the start if it is too long	*shm-t*
-		to fit on the command-line, "<" will appear in the left most
-		column; ignored in Ex mode
-	  T	truncate other messages in the middle if they are too	*shm-T*
-		long to fit on the command line; "..." will appear in the
-		middle; ignored in Ex mode
-	  W	don't give "written" or "[w]" when writing a file	*shm-W*
-	  A	don't give the "ATTENTION" message when an existing	*shm-A*
-		swap file is found
-	  I	don't give the intro message when starting Vim,		*shm-I*
-		see |:intro|
-	  c	don't give |ins-completion-menu| messages; for		*shm-c*
-		example, "-- XXX completion (YYY)", "match 1 of 2", "The only
-		match", "Pattern not found", "Back at original", etc.
-	  C	don't give messages while scanning for ins-completion	*shm-C*
-		items, for instance "scanning tags"
-	  q	use "recording" instead of "recording @a"		*shm-q*
-	  F	don't give the file info when editing a file, like	*shm-F*
-		`:silent` was used for the command; note that this also
-		affects messages from autocommands
-	  S	do not show search count message when searching, e.g.	*shm-S*
-		"[1/5]"
-
-	This gives you the opportunity to avoid that a change between buffers
-	requires you to hit <Enter>, but still gives as useful a message as
-	possible for the space available.  To get the whole message that you
-	would have got with 'shm' empty, use ":file!"
-	Useful values:
-	    shm=	No abbreviation of message.
-	    shm=a	Abbreviation, but no loss of information.
-	    shm=at	Abbreviation, and truncate message when necessary.
-
-	NOTE: This option is set to the Vi default value when 'compatible' is
-	set and to the Vim default value when 'compatible' is reset.
-
-				 *'shortname'* *'sn'* *'noshortname'* *'nosn'*
-'shortname' 'sn'	boolean	(default off)
-			local to buffer
-	Filenames are assumed to be 8 characters plus one extension of 3
-	characters.  Multiple dots in file names are not allowed.  When this
-	option is on, dots in file names are replaced with underscores when
-	adding an extension (".~" or ".swp").  This option is useful
-	when editing files on an MS-DOS compatible filesystem, e.g., messydos
-	or crossdos.
-
-						*'showbreak'* *'sbr'* *E595*
-'showbreak' 'sbr'	string	(default "")
-			global or local to window |global-local|
-			{not available when compiled without the |+linebreak|
-			feature}
-	String to put at the start of lines that have been wrapped.  Useful
-	values are "> " or "+++ ": >
-		:set showbreak=>\ 
-<	Note the backslash to escape the trailing space.  It's easier like
-	this: >
-		:let &showbreak = '+++ '
-<	Only printable single-cell characters are allowed, excluding <Tab> and
-	comma (in a future version the comma might be used to separate the
-	part that is shown at the end and at the start of a line).
-	The characters are highlighted according to the '@' flag in
-	'highlight'.
-	Note that tabs after the showbreak will be displayed differently.
-	If you want the 'showbreak' to appear in between line numbers, add the
-	"n" flag to 'cpoptions'.
-	A window-local value overrules a global value.  If the global value is
-	set and you want no value in the current window use NONE: >
-		:setlocal showbreak=NONE
-<
-				     *'showcmd'* *'sc'* *'noshowcmd'* *'nosc'*
-'showcmd' 'sc'		boolean	(Vim default: on, off for Unix,
-				       Vi default: off, set in |defaults.vim|)
-			global
-	Show (partial) command in the last line of the screen.  Set this
-	option off if your terminal is slow.
-	In Visual mode the size of the selected area is shown:
-	- When selecting characters within a line, the number of characters.
-	  If the number of bytes is different it is also displayed: "2-6"
-	  means two characters and six bytes.
-	- When selecting more than one line, the number of lines.
-	- When selecting a block, the size in screen characters:
-	  {lines}x{columns}.
-	This information can be displayed in an alternative location using the
-	'showcmdloc' option.
-	NOTE: This option is set to the Vi default value when 'compatible' is
-	set and to the Vim default value when 'compatible' is reset.
-
-			*'showcmdloc'* *'sloc'*
-'showcmdloc' 'sloc'	string	(default "last")
-			global
-	This option can be used to display the (partially) entered command in
-	another location.  Possible values are:
-	  last		Last line of the screen (default).
-	  statusline	Status line of the current window.
-	  tabline	First line of the screen if 'showtabline' is enabled.
-	Setting this option to "statusline" or "tabline" means that these will
-	be redrawn whenever the command changes, which can be on every key
-	pressed.
-	The %S 'statusline' item can be used in 'statusline' or 'tabline' to
-	place the text.  Without a custom 'statusline' or 'tabline' it will be
-	displayed in a convenient location.
-
-			*'showfulltag'* *'sft'* *'noshowfulltag'* *'nosft'*
-'showfulltag' 'sft'	boolean (default off)
-			global
-	When completing a word in insert mode (see |ins-completion|) from the
-	tags file, show both the tag name and a tidied-up form of the search
-	pattern (if there is one) as possible matches.  Thus, if you have
-	matched a C function, you can see a template for what arguments are
-	required (coding style permitting).
-	Note that this doesn't work well together with having "longest" in
-	'completeopt', because the completion from the search pattern may not
-	match the typed text.
-
-				 *'showmatch'* *'sm'* *'noshowmatch'* *'nosm'*
-'showmatch' 'sm'	boolean	(default off)
-			global
-	When a bracket is inserted, briefly jump to the matching one.  The
-	jump is only done if the match can be seen on the screen.  The time to
-	show the match can be set with 'matchtime'.
-	A Beep is given if there is no match (no matter if the match can be
-	seen or not).
-	This option is reset when 'paste' is set and restored when 'paste' is
-	reset.
-	When the 'm' flag is not included in 'cpoptions', typing a character
-	will immediately move the cursor back to where it belongs.
-	See the "sm" field in 'guicursor' for setting the cursor shape and
-	blinking when showing the match.
-	The 'matchpairs' option can be used to specify the characters to show
-	matches for.  'rightleft' and 'revins' are used to look for opposite
-	matches.
-	Also see the matchparen plugin for highlighting the match when moving
-	around |pi_paren.txt|.
-	Note: Use of the short form is rated PG.
-
-				 *'showmode'* *'smd'* *'noshowmode'* *'nosmd'*
-'showmode' 'smd'	boolean	(Vim default: on, Vi default: off)
-			global
-	If in Insert, Replace or Visual mode put a message on the last line.
-	Use the 'M' flag in 'highlight' to set the type of highlighting for
-	this message.
-	When |XIM| may be used the message will include "XIM".  But this
-	doesn't mean XIM is really active, especially when 'imactivatekey' is
-	not set.
-	NOTE: This option is set to the Vi default value when 'compatible' is
-	set and to the Vim default value when 'compatible' is reset.
-
-						*'showtabline'* *'stal'*
-'showtabline' 'stal'	number	(default 1)
-			global
-	The value of this option specifies when the line with tab page labels
-	will be displayed:
-		0: never
-		1: only if there are at least two tab pages
-		2: always
-	This is both for the GUI and non-GUI implementation of the tab pages
-	line.
-	See |tab-page| for more information about tab pages.
-
-						*'sidescroll'* *'ss'*
-'sidescroll' 'ss'	number	(default 0)
-			global
-	The minimal number of columns to scroll horizontally.  Used only when
-	the 'wrap' option is off and the cursor is moved off of the screen.
-	When it is zero the cursor will be put in the middle of the screen.
-	When using a slow terminal set it to a large number or 0.  When using
-	a fast terminal use a small number or 1.  Not used for "zh" and "zl"
-	commands.
-
-						*'sidescrolloff'* *'siso'*
-'sidescrolloff' 'siso'	number (default 0)
-			global or local to window |global-local|
-	The minimal number of screen columns to keep to the left and to the
-	right of the cursor if 'nowrap' is set.  Setting this option to a
-	value greater than 0 while having |'sidescroll'| also at a non-zero
-	value makes some context visible in the line you are scrolling in
-	horizontally (except at beginning of the line).  Setting this option
-	to a large value (like 999) has the effect of keeping the cursor
-	horizontally centered in the window, as long as one does not come too
-	close to the beginning of the line.
-	After using the local value, go back the global value with one of
-	these two: >
-		setlocal sidescrolloff<
-		setlocal sidescrolloff=-1
-<	NOTE: This option is set to 0 when 'compatible' is set.
-
-	Example: Try this together with 'sidescroll' and 'listchars' as
-		 in the following example to never allow the cursor to move
-		 onto the "extends" character: >
-
-		 :set nowrap sidescroll=1 listchars=extends:>,precedes:<
-		 :set sidescrolloff=1
-<
-						*'signcolumn'* *'scl'*
-'signcolumn' 'scl'	string	(default "auto")
-			local to window
-			{not available when compiled without the |+signs|
-			feature}
-	Whether or not to draw the signcolumn. Valid values are:
-	   "auto"	only when there is a sign to display
-	   "no"		never
-	   "yes"	always
-	   "number"	display signs in the 'number' column. If the number
-			column is not present, then behaves like "auto".
-
-
-			*'smartcase'* *'scs'* *'nosmartcase'* *'noscs'*
-'smartcase' 'scs'	boolean	(default off)
-			global
-	Override the 'ignorecase' option if the search pattern contains upper
-	case characters.  Only used when the search pattern is typed and
-	'ignorecase' option is on.  Used for the commands "/", "?", "n", "N",
-	":g" and ":s".  Not used for "*", "#", "gd", tag search, etc.  After
-	"*" and "#" you can make 'smartcase' used by doing a "/" command,
-	recalling the search pattern from history and hitting <Enter>.
-	NOTE: This option is reset when 'compatible' is set.
-
-			     *'smartindent'* *'si'* *'nosmartindent'* *'nosi'*
-'smartindent' 'si'	boolean	(default off)
-			local to buffer
-	Do smart autoindenting when starting a new line.  Works for C-like
-	programs, but can also be used for other languages.  'cindent' does
-	something like this, works better in most cases, but is more strict,
-	see |C-indenting|.  When 'cindent' is on or 'indentexpr' is set,
-	setting 'si' has no effect.  'indentexpr' is a more advanced
-	alternative.
-	Normally 'autoindent' should also be on when using 'smartindent'.
-	An indent is automatically inserted:
-	- After a line ending in '{'.
-	- After a line starting with a keyword from 'cinwords'.
-	- Before a line starting with '}' (only with the "O" command).
-	When typing '}' as the first character in a new line, that line is
-	given the same indent as the matching '{'.
-	When typing '#' as the first character in a new line, the indent for
-	that line is removed, the '#' is put in the first column.  The indent
-	is restored for the next line.  If you don't want this, use this
-	mapping: ":inoremap # X^H#", where ^H is entered with CTRL-V CTRL-H.
-	When using the ">>" command, lines starting with '#' are not shifted
-	right.
-	NOTE: This option is reset when 'compatible' is set.
-	This option is reset when 'paste' is set and restored when 'paste' is
-	reset.
-
-				 *'smarttab'* *'sta'* *'nosmarttab'* *'nosta'*
-'smarttab' 'sta'	boolean	(default off)
-			global
-	When on, a <Tab> in front of a line inserts blanks according to
-	'shiftwidth'.  'tabstop' or 'softtabstop' is used in other places.  A
-	<BS> will delete a 'shiftwidth' worth of space at the start of the
-	line.
-	When off, a <Tab> always inserts blanks according to 'tabstop' or
-	'softtabstop'.  'shiftwidth' is only used for shifting text left or
-	right |shift-left-right|.
-	What gets inserted (a <Tab> or spaces) depends on the 'expandtab'
-	option.  Also see |ins-expandtab|.  When 'expandtab' is not set, the
-	number of spaces is minimized by using <Tab>s.
-	This option is reset when 'paste' is set and restored when 'paste' is
-	reset.
-	NOTE: This option is reset when 'compatible' is set.
-
-			*'smoothscroll'* *'sms'* *'nosmoothscroll'* *'nosms'*
-'smoothscroll' 'sms'	boolean  (default off)
-			local to window
-	Scrolling works with screen lines.  When 'wrap' is set and the first
-	line in the window wraps part of it may not be visible, as if it is
-	above the window. "<<<" is displayed at the start of the first line,
-	highlighted with |hl-NonText|.
-	You may also want to add "lastline" to the 'display' option to show as
-	much of the last line as possible.
-	NOTE: only partly implemented, currently works with CTRL-E, CTRL-Y
-	and scrolling with the mouse.
-
-					*'softtabstop'* *'sts'*
-'softtabstop' 'sts'	number	(default 0)
-			local to buffer
-	Number of spaces that a <Tab> counts for while performing editing
-	operations, like inserting a <Tab> or using <BS>.  It "feels" like
-	<Tab>s are being inserted, while in fact a mix of spaces and <Tab>s is
-	used.  This is useful to keep the 'ts' setting at its standard value
-	of 8, while being able to edit like it is set to 'sts'.  However,
-	commands like "x" still work on the actual characters.
-	When 'sts' is zero, this feature is off.
-	When 'sts' is negative, the value of 'shiftwidth' is used.
-	'softtabstop' is set to 0 when the 'paste' option is set and restored
-	when 'paste' is reset.
-	See also |ins-expandtab|.  When 'expandtab' is not set, the number of
-	spaces is minimized by using <Tab>s.
-	The 'L' flag in 'cpoptions' changes how tabs are used when 'list' is
-	set.
-	NOTE: This option is set to 0 when 'compatible' is set.
-
-	If Vim is compiled with the |+vartabs| feature then the value of
-	'softtabstop' will be ignored if |'varsofttabstop'| is set to
-	anything other than an empty string.
-
-						*'spell'* *'nospell'*
-'spell'			boolean	(default off)
-			local to window
-			{not available when compiled without the |+syntax|
-			feature}
-	When on spell checking will be done.  See |spell|.
-	The languages are specified with 'spelllang'.
-
-						*'spellcapcheck'* *'spc'*
-'spellcapcheck' 'spc'	string	(default "[.?!]\_[\])'" \t]\+")
-			local to buffer
-			{not available when compiled without the |+syntax|
-			feature}
-	Pattern to locate the end of a sentence.  The following word will be
-	checked to start with a capital letter.  If not then it is highlighted
-	with SpellCap |hl-SpellCap| (unless the word is also badly spelled).
-	When this check is not wanted make this option empty.
-	Only used when 'spell' is set.
-	Be careful with special characters, see |option-backslash| about
-	including spaces and backslashes.
-	To set this option automatically depending on the language, see
-	|set-spc-auto|.
-
-						*'spellfile'* *'spf'*
-'spellfile' 'spf'	string	(default empty)
-			local to buffer
-			{not available when compiled without the |+syntax|
-			feature}
-	Name of the word list file where words are added for the |zg| and |zw|
-	commands.  It must end in ".{encoding}.add".  You need to include the
-	path, otherwise the file is placed in the current directory.
-	The path may include characters from 'isfname', space, comma and '@'.
-								*E765*
-	It may also be a comma-separated list of names.  A count before the
-	|zg| and |zw| commands can be used to access each.  This allows using
-	a personal word list file and a project word list file.
-	When a word is added while this option is empty Vim will set it for
-	you: Using the first directory in 'runtimepath' that is writable.  If
-	there is no "spell" directory yet it will be created.  For the file
-	name the first language name that appears in 'spelllang' is used,
-	ignoring the region.
-	The resulting ".spl" file will be used for spell checking, it does not
-	have to appear in 'spelllang'.
-	Normally one file is used for all regions, but you can add the region
-	name if you want to.  However, it will then only be used when
-	'spellfile' is set to it, for entries in 'spelllang' only files
-	without region name will be found.
-	This option cannot be set from a |modeline| or in the |sandbox|, for
-	security reasons.
-
-						*'spelllang'* *'spl'*
-'spelllang' 'spl'	string	(default "en")
-			local to buffer
-			{not available when compiled without the |+syntax|
-			feature}
-	A comma-separated list of word list names.  When the 'spell' option is
-	on spellchecking will be done for these languages.  Example: >
-		set spelllang=en_us,nl,medical
-<	This means US English, Dutch and medical words are recognized.  Words
-	that are not recognized will be highlighted.
-	The word list name must consist of alphanumeric characters, a dash or
-	an underscore.  It should not include a comma or dot.  Using a dash is
-	recommended to separate the two letter language name from a
-	specification.  Thus "en-rare" is used for rare English words.
-	A region name must come last and have the form "_xx", where "xx" is
-	the two-letter, lower case region name.  You can use more than one
-	region by listing them: "en_us,en_ca" supports both US and Canadian
-	English, but not words specific for Australia, New Zealand or Great
-	Britain. (Note: currently en_au and en_nz dictionaries are older than
-	en_ca, en_gb and en_us).
-	If the name "cjk" is included East Asian characters are excluded from
-	spell checking.  This is useful when editing text that also has Asian
-	words.
-	Note that the "medical" dictionary does not exist, it is just an
-	example of a longer name.
-							*E757*
-	As a special case the name of a .spl file can be given as-is.  The
-	first "_xx" in the name is removed and used as the region name
-	(_xx is an underscore, two letters and followed by a non-letter).
-	This is mainly for testing purposes.  You must make sure the correct
-	encoding is used, Vim doesn't check it.
-	When 'encoding' is set the word lists are reloaded.  Thus it's a good
-	idea to set 'spelllang' after setting 'encoding' to avoid loading the
-	files twice.
-	How the related spell files are found is explained here: |spell-load|.
-
-	If the |spellfile.vim| plugin is active and you use a language name
-	for which Vim cannot find the .spl file in 'runtimepath' the plugin
-	will ask you if you want to download the file.
-
-	After this option has been set successfully, Vim will source the files
-	"spell/LANG.vim" in 'runtimepath'.  "LANG" is the value of 'spelllang'
-	up to the first character that is not an ASCII letter or number and
-	not a dash.  Also see |set-spc-auto|.
-
-						*'spelloptions'* *'spo'*
-'spelloptions' 'spo'	string	(default "")
-			local to buffer
-			{not available when compiled without the |+syntax|
-			feature}
-	A comma-separated list of options for spell checking:
-	   camel	When a word is CamelCased, assume "Cased" is a
-			separate word: every upper-case character in a word
-			that comes after a lower case character indicates the
-			start of a new word.
-
-						*'spellsuggest'* *'sps'*
-'spellsuggest' 'sps'	string	(default "best")
-			global
-			{not available when compiled without the |+syntax|
-			feature}
-	Methods used for spelling suggestions.  Both for the |z=| command and
-	the |spellsuggest()| function.  This is a comma-separated list of
-	items:
-
-	best		Internal method that works best for English.  Finds
-			changes like "fast" and uses a bit of sound-a-like
-			scoring to improve the ordering.
-
-	double		Internal method that uses two methods and mixes the
-			results.  The first method is "fast", the other method
-			computes how much the suggestion sounds like the bad
-			word.  That only works when the language specifies
-			sound folding.  Can be slow and doesn't always give
-			better results.
-
-	fast		Internal method that only checks for simple changes:
-			character inserts/deletes/swaps.  Works well for
-			simple typing mistakes.
-
-	{number}	The maximum number of suggestions listed for |z=|.
-			Not used for |spellsuggest()|.  The number of
-			suggestions is never more than the value of 'lines'
-			minus two.
-
-	timeout:{millisec}   Limit the time searching for suggestions to
-			{millisec} milli seconds.  Applies to the following
-			methods.  When omitted the limit is 5000. When
-			negative there is no limit.  {only works when built
-			with the |+reltime| feature}
-
-	file:{filename} Read file {filename}, which must have two columns,
-			separated by a slash.  The first column contains the
-			bad word, the second column the suggested good word.
-			Example:
-				theribal/terrible ~
-			Use this for common mistakes that do not appear at the
-			top of the suggestion list with the internal methods.
-			Lines without a slash are ignored, use this for
-			comments.
-			The word in the second column must be correct,
-			otherwise it will not be used.  Add the word to an
-			".add" file if it is currently flagged as a spelling
-			mistake.
-			The file is used for all languages.
-
-	expr:{expr}	Evaluate expression {expr}.  Use a function to avoid
-			trouble with spaces.  Best is to call a function
-			without arguments, see |expr-option-function|.
-			|v:val| holds the badly spelled word.  The expression
-			must evaluate to a List of Lists, each with a
-			suggestion and a score.
-			Example:
-				[['the', 33], ['that', 44]] ~
-			Set 'verbose' and use |z=| to see the scores that the
-			internal methods use.  A lower score is better.
-			This may invoke |spellsuggest()| if you temporarily
-			set 'spellsuggest' to exclude the "expr:" part.
-			Errors are silently ignored, unless you set the
-			'verbose' option to a non-zero value.
-
-	Only one of "best", "double" or "fast" may be used.  The others may
-	appear several times in any order.  Example: >
-		:set sps=file:~/.vim/sugg,best,expr:MySuggest()
-<
-	This option cannot be set from a |modeline| or in the |sandbox|, for
-	security reasons.
-
-
-			*'splitbelow'* *'sb'* *'nosplitbelow'* *'nosb'*
-'splitbelow' 'sb'	boolean	(default off)
-			global
-	When on, splitting a window will put the new window below the current
-	one. |:split|
-
-			*'splitkeep'* *'spk'*
-'splitkeep' 'spk'	string	(default "cursor")
-			global
-	The value of this option determines the scroll behavior when opening,
-	closing or resizing horizontal splits.
-
-	Possible values are:
-	  cursor	Keep the same relative cursor position.
-	  screen	Keep the text on the same screen line.
-	  topline	Keep the topline the same.
-
-	For the "screen" and "topline" values, the cursor position will be
-	changed when necessary. In this case, the jumplist will be populated
-	with the previous cursor position. For "screen", the text cannot always

-
-			*'splitright'* *'spr'* *'nosplitright'* *'nospr'*
-'splitright' 'spr'	boolean	(default off)
-			global
-	When on, splitting a window will put the new window right of the
-	current one. |:vsplit|
-
-			   *'startofline'* *'sol'* *'nostartofline'* *'nosol'*
-'startofline' 'sol'	boolean	(default on)
-			global
-	When "on" the commands listed below move the cursor to the first
-	non-blank of the line.  When off the cursor is kept in the same column
-	(if possible).  This applies to the commands:
-	- CTRL-D, CTRL-U, CTRL-B, CTRL-F, "G", "H", "M", "L", "gg"
-	- "d", "<<" and ">>" with a linewise operator
-	- "%" with a count
-	- buffer changing commands (CTRL-^, :bnext, :bNext, etc.)
-	- Ex commands that only has a line number, e.g., ":25" or ":+".
-	In case of buffer changing commands the cursor is placed at the column
-	where it was the last time the buffer was edited.
-	NOTE: This option is set when 'compatible' is set.
-
-			   *'statusline'* *'stl'* *E540* *E542*
-'statusline' 'stl'	string	(default empty)
-			global or local to window |global-local|
-			{not available when compiled without the |+statusline|
-			feature}
-	When non-empty, this option determines the content of the status line.
-	Also see |status-line|.
-
-	The option consists of printf style '%' items interspersed with
-	normal text.  Each status line item is of the form:
-	  %-0{minwid}.{maxwid}{item}
-	All fields except the {item} are optional.  A single percent sign can
-	be given as "%%".
-
-	When the option starts with "%!" then it is used as an expression,
-	evaluated and the result is used as the option value.  Example: >
-		:set statusline=%!MyStatusLine()
-<	The *g:statusline_winid* variable will be set to the |window-ID| of the
-	window that the status line belongs to.
-	The result can contain %{} items that will be evaluated too.
-	Note that the "%!" expression is evaluated in the context of the
-	current window and buffer, while %{} items are evaluated in the
-	context of the window that the statusline belongs to.
-
-	When there is error while evaluating the option then it will be made
-	empty to avoid further errors.  Otherwise screen updating would loop.
-	When the result contains unprintable characters the result is
-	unpredictable.
-
-	Note that the only effect of 'ruler' when this option is set (and
-	'laststatus' is 2) is controlling the output of |CTRL-G|.
-
-	field	    meaning ~

-	0	    Leading zeroes in numeric items.  Overridden by '-'.
-	minwid	    Minimum width of the item, padding as set by '-' & '0'.
-		    Value must be 50 or less.
-	maxwid	    Maximum width of the item.  Truncation occurs with a '<'
-		    on the left for text items.  Numeric items will be
-		    shifted down to maxwid-2 digits followed by '>'number
-		    where number is the amount of missing digits, much like
-		    an exponential notation.
-	item	    A one letter code as described below.
-
-	Following is a description of the possible statusline items.  The
-	second character in "item" is the type:
-		N for number
-		S for string
-		F for flags as described below
-		- not applicable
-
-	item  meaning ~
-	f S   Path to the file in the buffer, as typed or relative to current
-	      directory.
-	F S   Full path to the file in the buffer.
-	t S   File name (tail) of file in the buffer.
-	m F   Modified flag, text is "[+]"; "[-]" if 'modifiable' is off.
-	M F   Modified flag, text is ",+" or ",-".
-	r F   Readonly flag, text is "[RO]".
-	R F   Readonly flag, text is ",RO".
-	h F   Help buffer flag, text is "[help]".
-	H F   Help buffer flag, text is ",HLP".
-	w F   Preview window flag, text is "[Preview]".
-	W F   Preview window flag, text is ",PRV".
-	y F   Type of file in the buffer, e.g., "[vim]".  See 'filetype'.
-	Y F   Type of file in the buffer, e.g., ",VIM".  See 'filetype'.
-	q S   "[Quickfix List]", "[Location List]" or empty.
-	k S   Value of "b:keymap_name" or 'keymap' when |:lmap| mappings are
-	      being used: "<keymap>"
-	n N   Buffer number.
-	b N   Value of character under cursor.
-	B N   As above, in hexadecimal.
-	o N   Byte number in file of byte under cursor, first byte is 1.
-	      Mnemonic: Offset from start of file (with one added)
-	      {not available when compiled without |+byte_offset| feature}
-	O N   As above, in hexadecimal.
-	N N   Printer page number.  (Only works in the 'printheader' option.)
-	l N   Line number.
-	L N   Number of lines in buffer.
-	c N   Column number (byte index).
-	v N   Virtual column number (screen column).
-	V N   Virtual column number as -{num}.  Not displayed if equal to 'c'.
-	p N   Percentage through file in lines as in |CTRL-G|.
-	P S   Percentage through file of displayed window.  This is like the
-	      percentage described for 'ruler'.  Always 3 in length, unless
-	      translated.
-	S S   'showcmd' content, see 'showcmdloc'.
-	a S   Argument list status as in default title.  ({current} of {max})
-	      Empty if the argument file count is zero or one.
-	{ NF  Evaluate expression between '%{' and '}' and substitute result.
-	      Note that there is no '%' before the closing '}'.  The
-	      expression cannot contain a '}' character, call a function to
-	      work around that.  See |stl-%{| below.
-	{% -  This is almost same as { except the result of the expression is
-	      re-evaluated as a statusline format string.  Thus if the
-	      return value of expr contains % items they will get expanded.
-	      The expression can contain the } character, the end of
-	      expression is denoted by %}.
-	      For example: >
-		func! Stl_filename() abort
-		    return "%t"
-		endfunc
-<	        `stl=%{Stl_filename()}`   results in `"%t"`
-	        `stl=%{%Stl_filename()%}` results in `"Name of current file"`
-	%} -  End of `{%` expression
-	( -   Start of item group.  Can be used for setting the width and
-	      alignment of a section.  Must be followed by %) somewhere.
-	) -   End of item group.  No width fields allowed.
-	T N   For 'tabline': start of tab page N label.  Use %T after the last
-	      label.  This information is used for mouse clicks.
-	X N   For 'tabline': start of close tab N label.  Use %X after the
-	      label, e.g.: %3Xclose%X.  Use %999X for a "close current tab"
-	      mark.  This information is used for mouse clicks.
-	< -   Where to truncate line if too long.  Default is at the start.
-	      No width fields allowed.
-	= -   Separation point between alignment sections.  Each section will
-	      be separated by an equal number of spaces.  With one %= what
-	      comes after it will be right-aligned.  With two %= there is a
-	      middle part, with white space left and right of it.
-	      No width fields allowed.
-	# -   Set highlight group.  The name must follow and then a # again.
-	      Thus use %#HLname# for highlight group HLname.  The same
-	      highlighting is used, also for the statusline of non-current
-	      windows.
-	* -   Set highlight group to User{N}, where {N} is taken from the
-	      minwid field, e.g. %1*.  Restore normal highlight with %* or %0*.
-	      The difference between User{N} and StatusLine will be applied to
-	      StatusLineNC for the statusline of non-current windows.
-	      The number N must be between 1 and 9.  See |hl-User1..9|
-
-	When displaying a flag, Vim removes the leading comma, if any, when
-	that flag comes right after plaintext.  This will make a nice display
-	when flags are used like in the examples below.
-
-	When all items in a group becomes an empty string (i.e. flags that are
-	not set) and a minwid is not set for the group, the whole group will
-	become empty.  This will make a group like the following disappear
-	completely from the statusline when none of the flags are set. >
-		:set statusline=...%(\ [%M%R%H]%)...
-<	Beware that an expression is evaluated each and every time the status
-	line is displayed.
-				*stl-%{* *g:actual_curbuf* *g:actual_curwin*
-	While evaluating %{} the current buffer and current window will be set
-	temporarily to that of the window (and buffer) whose statusline is
-	currently being drawn.  The expression will evaluate in this context.
-	The variable "g:actual_curbuf" is set to the `bufnr()` number of the
-	real current buffer and "g:actual_curwin" to the |window-ID| of the
-	real current window.  These values are strings.
-
-	The 'statusline' option will be evaluated in the |sandbox| if set from
-	a modeline, see |sandbox-option|.
-	This option cannot be set in a modeline when 'modelineexpr' is off.
-
-	It is not allowed to change text or jump to another window while
-	evaluating 'statusline' |textlock|.
-
-	If the statusline is not updated when you want it (e.g., after setting
-	a variable that's used in an expression), you can force an update by
-	using `:redrawstatus`.
-
-	A result of all digits is regarded a number for display purposes.
-	Otherwise the result is taken as flag text and applied to the rules
-	described above.
-
-	Watch out for errors in expressions.  They may render Vim unusable!
-	If you are stuck, hold down ':' or 'Q' to get a prompt, then quit and
-	edit your .vimrc or whatever with "vim --clean" to get it right.
-
-	Examples:
-	Emulate standard status line with 'ruler' set >
-	  :set statusline=%<%f\ %h%m%r%=%-14.(%l,%c%V%)\ %P
-<	Similar, but add ASCII value of char under the cursor (like "ga") >
-	  :set statusline=%<%f%h%m%r%=%b\ 0x%B\ \ %l,%c%V\ %P

-						*'suffixes'* *'su'*
-'suffixes' 'su'		string	(default ".bak,~,.o,.h,.info,.swp,.obj")
-			global
-	Files with these suffixes get a lower priority when multiple files
-	match a wildcard.  See |suffixes|.  Commas can be used to separate the
-	suffixes.  Spaces after the comma are ignored.  A dot is also seen as
-	the start of a suffix.  To avoid a dot or comma being recognized as a
-	separator, precede it with a backslash (see |option-backslash| about
-	including spaces and backslashes).
-	See 'wildignore' for completely ignoring files.
-	The use of |:set+=| and |:set-=| is preferred when adding or removing
-	suffixes from the list.  This avoids problems when a future version
-	uses another default.
-
-						*'suffixesadd'* *'sua'*
-'suffixesadd' 'sua'	string	(default "")
-			local to buffer
-	Comma-separated list of suffixes, which are used when searching for a
-	file for the "gf", "[I", etc. commands.  Example: >
-		:set suffixesadd=.java
-<
-				*'swapfile'* *'swf'* *'noswapfile'* *'noswf'*
-'swapfile' 'swf'	boolean (default on)
-			local to buffer
-	Use a swapfile for the buffer.  This option can be reset when a
-	swapfile is not wanted for a specific buffer.  For example, with
-	confidential information that even root must not be able to access.
-	Careful: All text will be in memory:
-		- Don't use this for big files.
-		- Recovery will be impossible!
-	A swapfile will only be present when |'updatecount'| is non-zero and
-	'swapfile' is set.
-	When 'swapfile' is reset, the swap file for the current buffer is
-	immediately deleted.  When 'swapfile' is set, and 'updatecount' is
-	non-zero, a swap file is immediately created.
-	Also see |swap-file| and |'swapsync'|.
-	If you want to open a new buffer without creating a swap file for it,
-	use the |:noswapfile| modifier.
-	See 'directory' for where the swap file is created.
-
-	This option is used together with 'bufhidden' and 'buftype' to
-	specify special kinds of buffers.   See |special-buffers|.
-
-						*'swapsync'* *'sws'*
-'swapsync' 'sws'	string	(default "fsync")
-			global
-	When this option is not empty a swap file is synced to disk after
-	writing to it.  This takes some time, especially on busy unix systems.
-	When this option is empty parts of the swap file may be in memory and
-	not written to disk.  When the system crashes you may lose more work.
-	On Unix the system does a sync now and then without Vim asking for it,
-	so the disadvantage of setting this option off is small.  On some
-	systems the swap file will not be written at all.  For a unix system
-	setting it to "sync" will use the sync() call instead of the default
-	fsync(), which may work better on some systems.
-	The 'fsync' option is used for the actual file.
-
-						*'switchbuf'* *'swb'*
-'switchbuf' 'swb'	string	(default "")
-			global
-	This option controls the behavior when switching between buffers.
-	This option is checked, when
-	- jumping to errors with the |quickfix| commands (|:cc|, |:cn|, |:cp|,
-	  etc.)
-	- jumping to a tag using the |:stag| command.
-	- opening a file using the |CTRL-W_f| or |CTRL-W_F| command.
-	- jumping to a buffer using a buffer split command (e.g.  |:sbuffer|,
-	  |:sbnext|, or |:sbrewind|).
-	Possible values (comma-separated list):
-	   useopen	If included, jump to the first open window in the
-			current tab page that contains the specified buffer
-			(if there is one).  Otherwise: Do not examine other
-			windows.
-	   usetab	Like "useopen", but also consider windows in other tab
-			pages.
-	   split	If included, split the current window before loading
-			a buffer for a |quickfix| command that display errors.
-			Otherwise: do not split, use current window (when used
-			in the quickfix window: the previously used window or
-			split if there is no other window).
-	   vsplit	Just like "split" but split vertically.
-	   newtab	Like "split", but open a new tab page.  Overrules
-			"split" when both are present.
-	   uselast	If included, jump to the previously used window when
-			jumping to errors with |quickfix| commands.
-
-						*'synmaxcol'* *'smc'*
-'synmaxcol' 'smc'	number	(default 3000)
-			local to buffer
-			{not available when compiled without the |+syntax|
-			feature}
-	Maximum column in which to search for syntax items.  In long lines the
-	text after this column is not highlighted and following lines may not
-	be highlighted correctly, because the syntax state is cleared.
-	This helps to avoid very slow redrawing for an XML file that is one
-	long line.
-	Set to zero to remove the limit.
-
-						*'syntax'* *'syn'*
-'syntax' 'syn'		string	(default empty)
-			local to buffer
-			{not available when compiled without the |+syntax|
-			feature}
-	When this option is set, the syntax with this name is loaded, unless
-	syntax highlighting has been switched off with ":syntax off".
-	Otherwise this option does not always reflect the current syntax (the
-	b:current_syntax variable does).
-	This option is most useful in a modeline, for a file which syntax is
-	not automatically recognized.  Example, in an IDL file:
-		/* vim: set syntax=idl : */ ~
-	When a dot appears in the value then this separates two filetype
-	names.  Example:
-		/* vim: set syntax=c.doxygen : */ ~
-	This will use the "c" syntax first, then the "doxygen" syntax.
-	Note that the second one must be prepared to be loaded as an addition,
-	otherwise it will be skipped.  More than one dot may appear.
-	To switch off syntax highlighting for the current file, use: >
-		:set syntax=OFF
-<	To switch syntax highlighting on according to the current value of the
-	'filetype' option: >
-		:set syntax=ON
-<	What actually happens when setting the 'syntax' option is that the
-	Syntax autocommand event is triggered with the value as argument.
-	This option is not copied to another buffer, independent of the 's' or
-	'S' flag in 'cpoptions'.
-	Only normal file name characters can be used, "/\*?[|<>" are illegal.
-
-						*'tabline'* *'tal'*
-'tabline' 'tal'		string	(default empty)
-			global
-	When non-empty, this option determines the content of the tab pages
-	line at the top of the Vim window.  When empty Vim will use a default
-	tab pages line.  See |setting-tabline| for more info.
-
-	The tab pages line only appears as specified with the 'showtabline'
-	option and only when there is no GUI tab line.  When 'e' is in
-	'guioptions' and the GUI supports a tab line 'guitablabel' is used
-	instead.  Note that the two tab pages lines are very different.
-
-	The value is evaluated like with 'statusline'.  You can use
-	|tabpagenr()|, |tabpagewinnr()| and |tabpagebuflist()| to figure out
-	the text to be displayed.  Use "%1T" for the first label, "%2T" for
-	the second one, etc.  Use "%X" items for closing labels.
-
-	When changing something that is used in 'tabline' that does not
-	trigger it to be updated, use |:redrawtabline|.
-	This option cannot be set in a modeline when 'modelineexpr' is off.
-
-	Keep in mind that only one of the tab pages is the current one, others
-	are invisible and you can't jump to their windows.
-
-
-						*'tabpagemax'* *'tpm'*
-'tabpagemax' 'tpm'	number	(default 10)
-			global
-	Maximum number of tab pages to be opened by the |-p| command line
-	argument or the ":tab all" command. |tabpage|
-
-
-						*'tabstop'* *'ts'*
-'tabstop' 'ts'		number	(default 8)
-			local to buffer
-	Number of spaces that a <Tab> in the file counts for.  Also see
-	the |:retab| command, and the 'softtabstop' option.
-
-	Note: Setting 'tabstop' to any other value than 8 can make your file
-	appear wrong in many places, e.g., when printing it.
-	The value must be more than 0 and less than 10000.
-
-	There are four main ways to use tabs in Vim:
-	1. Always keep 'tabstop' at 8, set 'softtabstop' and 'shiftwidth' to 4
-	   (or 3 or whatever you prefer) and use 'noexpandtab'.  Then Vim
-	   will use a mix of tabs and spaces, but typing <Tab> and <BS> will
-	   behave like a tab appears every 4 (or 3) characters.
-	   This is the recommended way, the file will look the same with other
-	   tools and when listing it in a terminal.
-	2. Set 'softtabstop' and 'shiftwidth' to whatever you prefer and use
-	   'expandtab'.  This way you will always insert spaces.  The
-	   formatting will never be messed up when 'tabstop' is changed (leave
-	   it at 8 just in case).  The file will be a bit larger.
-	   You do need to check if no Tabs exist in the file.  You can get rid
-	   of them by first setting 'expandtab' and using `%retab!`, making
-	   sure the value of 'tabstop' is set correctly.
-	3. Set 'tabstop' and 'shiftwidth' to whatever you prefer and use
-	   'expandtab'.  This way you will always insert spaces.  The
-	   formatting will never be messed up when 'tabstop' is changed.
-	   You do need to check if no Tabs exist in the file, just like in the
-	   item just above.
-	4. Set 'tabstop' and 'shiftwidth' to whatever you prefer and use a
-	   |modeline| to set these values when editing the file again.  Only
-	   works when using Vim to edit the file, other tools assume a tabstop
-	   is worth 8 spaces.
-	5. Always set 'tabstop' and 'shiftwidth' to the same value, and
-	   'noexpandtab'.  This should then work (for initial indents only)
-	   for any tabstop setting that people use.  It might be nice to have
-	   tabs after the first non-blank inserted as spaces if you do this
-	   though.  Otherwise aligned comments will be wrong when 'tabstop' is
-	   changed.
-
-	If Vim is compiled with the |+vartabs| feature then the value of
-	'tabstop' will be ignored if |'vartabstop'| is set to anything other
-	than an empty string.
-
-			*'tagbsearch'* *'tbs'* *'notagbsearch'* *'notbs'*
-'tagbsearch' 'tbs'	boolean	(default on)
-			global
-	When searching for a tag (e.g., for the |:ta| command), Vim can either
-	use a binary search or a linear search in a tags file.  Binary
-	searching makes searching for a tag a LOT faster, but a linear search
-	will find more tags if the tags file wasn't properly sorted.
-	Vim normally assumes that your tags files are sorted, or indicate that
-	they are not sorted.  Only when this is not the case does the
-	'tagbsearch' option need to be switched off.
-
-	When 'tagbsearch' is on, binary searching is first used in the tags
-	files.  In certain situations, Vim will do a linear search instead for
-	certain files, or retry all files with a linear search.  When
-	'tagbsearch' is off, only a linear search is done.
-
-	Linear searching is done anyway, for one file, when Vim finds a line
-	at the start of the file indicating that it's not sorted: >
-   !_TAG_FILE_SORTED	0	/some comment/
-<	[The whitespace before and after the '0' must be a single <Tab>]
-
-	When a binary search was done and no match was found in any of the
-	files listed in 'tags', and case is ignored or a pattern is used
-	instead of a normal tag name, a retry is done with a linear search.
-	Tags in unsorted tags files, and matches with different case will only
-	be found in the retry.
-
-	If a tag file indicates that it is case-fold sorted, the second,
-	linear search can be avoided when case is ignored.  Use a value of '2'
-	in the "!_TAG_FILE_SORTED" line for this.  A tag file can be case-fold
-	sorted with the -f switch to "sort" in most unices, as in the command:
-	"sort -f -o tags tags".  For Universal ctags and Exuberant ctags
-	version 5.x or higher (at least 5.5) the --sort=foldcase switch can be
-	used for this as well.  Note that case must be folded to uppercase for
-	this to work.
-
-	By default, tag searches are case-sensitive.  Case is ignored when
-	'ignorecase' is set and 'tagcase' is "followic", or when 'tagcase' is
-	"ignore".
-	Also when 'tagcase' is "followscs" and 'smartcase' is set, or
-	'tagcase' is "smart", and the pattern contains only lowercase
-	characters.
-
-	When 'tagbsearch' is off, tags searching is slower when a full match
-	exists, but faster when no full match exists.  Tags in unsorted tags
-	files may only be found with 'tagbsearch' off.
-	When the tags file is not sorted, or sorted in a wrong way (not on
-	ASCII byte value), 'tagbsearch' should be off, or the line given above
-	must be included in the tags file.
-	This option doesn't affect commands that find all matching tags (e.g.,
-	command-line completion and ":help").
-
-							*'tagcase'* *'tc'*
-'tagcase' 'tc'		string	(default "followic")
-			global or local to buffer |global-local|
-	This option specifies how case is handled when searching the tags
-	file:
-	   followic	Follow the 'ignorecase' option
-	   followscs    Follow the 'smartcase' and 'ignorecase' options
-	   ignore	Ignore case
-	   match	Match case
-	   smart	Ignore case unless an upper case letter is used
-	NOTE: This option is set to the Vi default value when 'compatible' is
-	set and to the Vim default value when 'compatible' is reset.
-
-							*'tagfunc'* *'tfu'*
-'tagfunc' 'tfu'		string	(default: empty)
-			local to buffer
-			{not available when compiled without the |+eval|
-			feature}
-	This option specifies a function to be used to perform tag searches.
-	The function gets the tag pattern and should return a List of matching
-	tags.  See |tag-function| for an explanation of how to write the
-	function and an example.  The value can be the name of a function, a
-	|lambda| or a |Funcref|. See |option-value-function| for more
-	information.
-
-						*'taglength'* *'tl'*
-'taglength' 'tl'	number	(default 0)
-			global
-	If non-zero, tags are significant up to this number of characters.
-
-			*'tagrelative'* *'tr'* *'notagrelative'* *'notr'*
-'tagrelative' 'tr'	boolean	(Vim default: on, Vi default: off)
-			global
-	If on and using a tags file in another directory, file names in that
-	tags file are relative to the directory where the tags file is.
-	NOTE: This option is set to the Vi default value when 'compatible' is
-	set and to the Vim default value when 'compatible' is reset.
-
-						*'tags'* *'tag'* *E433*
-'tags' 'tag'		string	(default "./tags,tags", when compiled with
-				|+emacs_tags|: "./tags,./TAGS,tags,TAGS")
-			global or local to buffer |global-local|
-	Filenames for the tag command, separated by spaces or commas.  To
-	include a space or comma in a file name, precede it with a backslash
-	(see |option-backslash| about including spaces and backslashes).
-	When a file name starts with "./", the '.' is replaced with the path
-	of the current file.  But only when the 'd' flag is not included in
-	'cpoptions'.  Environment variables are expanded |:set_env|.  Also see
-	|tags-option|.
-	"*", "**" and other wildcards can be used to search for tags files in
-	a directory tree.  See |file-searching|.  E.g., "/lib/**/tags" will
-	find all files named "tags" below "/lib".  The filename itself cannot
-	contain wildcards, it is used as-is.  E.g., "/lib/**/tags?" will find
-	files called "tags?".
-	The |tagfiles()| function can be used to get a list of the file names
-	actually used.
-	If Vim was compiled with the |+emacs_tags| feature, Emacs-style tag
-	files are also supported.  They are automatically recognized.  The
-	default value becomes "./tags,./TAGS,tags,TAGS", unless case
-	differences are ignored (MS-Windows).  |emacs-tags|
-	The use of |:set+=| and |:set-=| is preferred when adding or removing
-	file names from the list.  This avoids problems when a future version
-	uses another default.
-
-				*'tagstack'* *'tgst'* *'notagstack'* *'notgst'*
-'tagstack' 'tgst'	boolean	(default on)
-			global
-	When on, the |tagstack| is used normally.  When off, a ":tag" or
-	":tselect" command with an argument will not push the tag onto the
-	tagstack.  A following ":tag" without an argument, a ":pop" command or
-	any other command that uses the tagstack will use the unmodified
-	tagstack, but does change the pointer to the active entry.
-	Resetting this option is useful when using a ":tag" command in a
-	mapping which should not change the tagstack.
-
-						*'tcldll'*
-'tcldll'		string	(default depends on the build)
-			global
-			{only available when compiled with the |+tcl/dyn|
-			feature}
-	Specifies the name of the Tcl shared library. The default is
-	DYNAMIC_TCL_DLL, which was specified at compile time.
-	Environment variables are expanded |:set_env|.
-	This option cannot be set from a |modeline| or in the |sandbox|, for
-	security reasons.
-
-						*'term'* *E529* *E530* *E531*
-'term'			string	(default is $TERM, if that fails:
-				      in the GUI: "builtin_gui"
-					on Amiga: "amiga"
-					on Haiku: "xterm"
-					  on Mac: "mac-ansi"
-					 on Unix: "ansi"
-					  on VMS: "ansi"
-				       on Win 32: "win32")
-			global
-	Name of the terminal.  Used for choosing the terminal control
-	characters.  Environment variables are expanded |:set_env|.
-	For example: >
-		:set term=$TERM
-<	See |termcap|.
-
-						*'termbidi'* *'tbidi'*
-						*'notermbidi'* *'notbidi'*
-'termbidi' 'tbidi'	boolean (default off, on for "mlterm")
-			global
-			{only available when compiled with the |+arabic|
-			feature}
-	The terminal is in charge of Bi-directionality of text (as specified
-	by Unicode).  The terminal is also expected to do the required shaping
-	that some languages (such as Arabic) require.
-	Setting this option implies that 'rightleft' will not be set when
-	'arabic' is set and the value of 'arabicshape' will be ignored.
-	Note that setting 'termbidi' has the immediate effect that
-	'arabicshape' is ignored, but 'rightleft' isn't changed automatically.
-	This option is reset when the GUI is started.
-	For further details see |arabic.txt|.
-
-					*'termencoding'* *'tenc'*
-'termencoding' 'tenc'	string	(default ""; with GTK+ GUI: "utf-8")
-			global
-	Encoding used for the terminal.  This specifies what character
-	encoding the keyboard produces and the display will understand.  For
-	the GUI it only applies to the keyboard ('encoding' is used for the
-	display).
-								*E617* *E950*
-	Note: This does not apply to the GTK+ GUI.  After the GUI has been
-	successfully initialized, 'termencoding' is forcibly set to "utf-8".
-	Any attempts to set a different value will be rejected, and an error
-	message is shown.
-	For the Win32 GUI and console versions 'termencoding' is not used,
-	because the Win32 system always passes Unicode characters.
-	When empty, the same encoding is used as for the 'encoding' option.
-	This is the normal value.
-	Not all combinations for 'termencoding' and 'encoding' are valid.  See
-	|encoding-table|.
-	The value for this option must be supported by internal conversions or
-	iconv().  When this is not possible no conversion will be done and you
-	will probably experience problems with non-ASCII characters.
-	Example: You are working with the locale set to euc-jp (Japanese) and
-	want to edit a UTF-8 file: >
-		:let &termencoding = &encoding
-		:set encoding=utf-8
-<	You need to do this when your system has no locale support for UTF-8.
-
-		*'termguicolors'* *'tgc'* *'notermguicolors'* *'notgc'* *E954*
-'termguicolors' 'tgc'	boolean (default off)
-			global
-			{not available when compiled without the
-			|+termguicolors| feature}
-	When on, uses |highlight-guifg| and |highlight-guibg| attributes in
-	the terminal (thus using 24-bit color).
-
-	Requires a ISO-8613-3 compatible terminal.  If setting this option
-	does not work (produces a colorless UI) reading |xterm-true-color|
-	might help.
-
-	For Win32 console, Windows 10 version 1703 (Creators Update) or later
-	is required. Use this check to find out: >
-		if has('vcon')
-<	This requires Vim to be built with the |+vtp| feature.
-
-	Note that the "cterm" attributes are still used, not the "gui" ones.
-
-	When using Vim with Windows Terminal, the background of Windows
-	Terminal is normally filled with the Vim background color.  Setting
-	'termguicolors' and the guibg of the Normal highlight group to NONE
-	will make the background transparent: >
-		:hi Normal guibg=NONE
-<
-	NOTE: This option is reset when 'compatible' is set.
-
-						*'termwinkey'* *'twk'*
-'termwinkey' 'twk'	string	(default "")
-			local to window
-	The key that starts a CTRL-W command in a terminal window.  Other keys
-	are sent to the job running in the window.
-	The <> notation can be used, e.g.: >
-		:set termwinkey=<C-L>
-<	The string must be one key stroke but can be multiple bytes.
-	When not set CTRL-W is used, so that CTRL-W : gets you to the command
-	line.  If 'termwinkey' is set to CTRL-L then CTRL-L : gets you to the
-	command line.
-
-						*'termwinscroll'* *'twsl'*
-'termwinscroll' 'twsl'	number	(default 10000)
-			local to buffer
-			{not available when compiled without the
-			|+terminal| feature}
-	Number of scrollback lines to keep.  When going over this limit the
-	first 10% of the scrollback lines are deleted.  This is just to reduce
-	the memory usage.  See |Terminal-Normal|.
-	Also used as a limit for text sent to the terminal in one write,
-	multiplied by the number of columns times 3 (average number of bytes
-	per cell).
-
-						*'termwinsize'* *'tws'*
-'termwinsize' 'tws'	string	(default "")
-			local to window
-	Size used when opening the |terminal| window.  Format:
-		{rows}x{columns} or {rows}*{columns}.
-	- When empty the terminal gets the size from the window.
-	- When set with a "x" (e.g., "24x80") the terminal size is not
-	  adjusted to the window size.  If the window is smaller only the
-	  top-left part is displayed.
-	- When set with a "*" (e.g., "10*50") the terminal size follows the
-	  window size, but will not be smaller than the specified rows and/or
-	  columns.
-	- When rows is zero then use the height of the window.
-	- When columns is zero then use the width of the window.
-	- Using "0x0" or "0*0" is the same as empty.
-	- Can be overruled in the |term_start()| options with "term_rows" and
-	  "term_cols".
-
-	Examples:
-	  "30x0" uses 30 rows and the current window width.
-	  "20*0" uses at least 20 rows and the current window width.
-	  "0*40" uses the current window height and at least 40 columns.
-	Note that the command running in the terminal window may still change
-	the size of the terminal.  In that case the Vim window will be
-	adjusted to that size, if possible.
-
-						*'termwintype'* *'twt'*
-'termwintype' 'twt'	string  (default "")
-			global
-			{only available when compiled with the |terminal|
-			feature on MS-Windows}
-	Specify the virtual console (pty) used when opening the terminal
-	window.
-
-	Possible values are:
-	    ""		use ConPTY if it is stable, winpty otherwise
-	    "winpty"	use winpty, fail if not supported
-	    "conpty"	use |ConPTY|, fail if not supported
-
-	|ConPTY| support depends on the platform.  Windows 10 October 2018
-	Update is the first version that supports ConPTY, however it is still
-	considered unstable.  ConPTY might become stable in the next release
-	of Windows 10.  winpty support needs to be installed.  If neither is
-	supported then you cannot open a terminal window.
-
-						*'terse'* *'noterse'*
-'terse'			boolean	(default off)
-			global
-	When set: Add 's' flag to 'shortmess' option (this makes the message
-	for a search that hits the start or end of the file not being
-	displayed).  When reset: Remove 's' flag from 'shortmess' option.  {Vi
-	shortens a lot of messages}
-
-				   *'textauto'* *'ta'* *'notextauto'* *'nota'*
-'textauto' 'ta'		boolean	(Vim default: on, Vi default: off)
-			global
-	This option is obsolete.  Use 'fileformats'.
-	For backwards compatibility, when 'textauto' is set, 'fileformats' is
-	set to the default value for the current system.  When 'textauto' is
-	reset, 'fileformats' is made empty.
-	NOTE: This option is set to the Vi default value when 'compatible' is
-	set and to the Vim default value when 'compatible' is reset.
-
-				   *'textmode'* *'tx'* *'notextmode'* *'notx'*
-'textmode' 'tx'		boolean	(Win32: default on,
-				 others: default off)
-			local to buffer
-	This option is obsolete.  Use 'fileformat'.
-	For backwards compatibility, when 'textmode' is set, 'fileformat' is
-	set to "dos".  When 'textmode' is reset, 'fileformat' is set to
-	"unix".
-
-						*'textwidth'* *'tw'*
-'textwidth' 'tw'	number	(default 0)
-			local to buffer
-	Maximum width of text that is being inserted.  A longer line will be
-	broken after white space to get this width.  A zero value disables
-	this.
-	'textwidth' is set to 0 when the 'paste' option is set and restored
-	when 'paste' is reset.
-	When 'textwidth' is zero, 'wrapmargin' may be used.  See also
-	'formatoptions' and |ins-textwidth|.
-	When 'formatexpr' is set it will be used to break the line.
-	NOTE: This option is set to 0 when 'compatible' is set.
-
-						*'thesaurus'* *'tsr'*
-'thesaurus' 'tsr'	string	(default "")
-			global or local to buffer |global-local|
-	List of file names, separated by commas, that are used to lookup words
-	for thesaurus completion commands |i_CTRL-X_CTRL-T|.  See
-	|compl-thesaurus|.
-
-	This option is not used if 'thesaurusfunc' is set, either for the
-	buffer or globally.
-
-	To include a comma in a file name precede it with a backslash.  Spaces
-	after a comma are ignored, otherwise spaces are included in the file
-	name.  See |option-backslash| about using backslashes.  The use of
-	|:set+=| and |:set-=| is preferred when adding or removing directories
-	from the list.  This avoids problems when a future version uses
-	another default.  Backticks cannot be used in this option for security
-	reasons.
-
-						*'thesaurusfunc'* *'tsrfu'*
-'thesaurusfunc' 'tsrfu'	string	(default: empty)
-			global or local to buffer |global-local|
-			{not available when compiled without the |+eval|
-			feature}
-	This option specifies a function to be used for thesaurus completion
-	with CTRL-X CTRL-T. |i_CTRL-X_CTRL-T| See |compl-thesaurusfunc|.
-	The value can be the name of a function, a |lambda| or a |Funcref|.
-	See |option-value-function| for more information.
-
-	This option cannot be set from a |modeline| or in the |sandbox|, for
-	security reasons.
-
-			     *'tildeop'* *'top'* *'notildeop'* *'notop'*
-'tildeop' 'top'		boolean	(default off)
-			global
-	When on: The tilde command "~" behaves like an operator.
-	NOTE: This option is reset when 'compatible' is set.
-
-				*'timeout'* *'to'* *'notimeout'* *'noto'*
-'timeout' 'to'		boolean (default on)
-			global
-						*'ttimeout'* *'nottimeout'*
-'ttimeout'		boolean (default off, set in |defaults.vim|)
-			global
-	These two options together determine the behavior when part of a
-	mapped key sequence or keyboard code has been received:
-
-	'timeout'    'ttimeout'		action	~
-	   off		off		do not time out
-	   on		on or off	time out on :mappings and key codes
-	   off		on		time out on key codes
-
-	If both options are off, Vim will wait until either the complete
-	mapping or key sequence has been received, or it is clear that there
-	is no mapping or key sequence for the received characters.  For
-	example: if you have mapped "vl" and Vim has received 'v', the next
-	character is needed to see if the 'v' is followed by an 'l'.
-	When one of the options is on, Vim will wait for about 1 second for
-	the next character to arrive.  After that the already received
-	characters are interpreted as single characters.  The waiting time can
-	be changed with the 'timeoutlen' option.
-	On slow terminals or very busy systems timing out may cause
-	malfunctioning cursor keys.  If both options are off, Vim waits
-	forever after an entered <Esc> if there are key codes that start
-	with <Esc>.  You will have to type <Esc> twice.  If you do not have
-	problems with key codes, but would like to have :mapped key
-	sequences not timing out in 1 second, set the 'ttimeout' option and
-	reset the 'timeout' option.
-
-	NOTE: 'ttimeout' is reset when 'compatible' is set.
-
-						*'timeoutlen'* *'tm'*
-'timeoutlen' 'tm'	number	(default 1000)
-			global
-
-						*'ttimeoutlen'* *'ttm'*
-'ttimeoutlen' 'ttm'	number	(default -1, set to 100 in |defaults.vim|)
-			global
-	The time in milliseconds that is waited for a key code or mapped key
-	sequence to complete.  Also used for CTRL-\ CTRL-N and CTRL-\ CTRL-G
-	when part of a command has been typed.
-	Normally only 'timeoutlen' is used and 'ttimeoutlen' is -1.  When a
-	different timeout value for key codes is desired set 'ttimeoutlen' to
-	a non-negative number.
-
-		ttimeoutlen	mapping delay	   key code delay	~
-		   < 0		'timeoutlen'	   'timeoutlen'
-		  >= 0		'timeoutlen'	   'ttimeoutlen'
-
-	The timeout only happens when the 'timeout' and 'ttimeout' options
-	tell so.  A useful setting would be >
-		:set timeout timeoutlen=3000 ttimeoutlen=100
-<	(time out on mapping after three seconds, time out on key codes after
-	a tenth of a second).
-
-						*'title'* *'notitle'*
-'title'			boolean	(default off, on when title can be restored)
-			global
-	When on, the title of the window will be set to the value of
-	'titlestring' (if it is not empty), or to:
-		filename [+=-] (path) - VIM
-	Where:
-		filename	the name of the file being edited
-		-		indicates the file cannot be modified, 'ma' off
-		+		indicates the file was modified
-		=		indicates the file is read-only
-		=+		indicates the file is read-only and modified
-		(path)		is the path of the file being edited
-		- VIM		the server name |v:servername| or "VIM"
-	Only works if the terminal supports setting window titles
-	(currently Amiga console, Win32 console, all GUI versions and
-	terminals with a non-empty 't_ts' option - these are Unix xterm and
-	iris-ansi by default, where 't_ts' is taken from the builtin termcap).
-								*X11*
-	When Vim was compiled with HAVE_X11 defined, the original title will
-	be restored if possible.  The output of ":version" will include "+X11"
-	when HAVE_X11 was defined, otherwise it will be "-X11".  This also
-	works for the icon name |'icon'|.
-	But: When Vim was started with the |-X| argument, restoring the title
-	will not work (except in the GUI).
-	If the title cannot be restored, it is set to the value of 'titleold'.
-	You might want to restore the title outside of Vim then.
-	When using an xterm from a remote machine you can use this command:
-	    rsh machine_name xterm -display $DISPLAY &
-	then the WINDOWID environment variable should be inherited and the
-	title of the window should change back to what it should be after
-	exiting Vim.
-
-								*'titlelen'*
-'titlelen'		number	(default 85)
-			global
-	Gives the percentage of 'columns' to use for the length of the window
-	title.  When the title is longer, only the end of the path name is
-	shown.  A '<' character before the path name is used to indicate this.
-	Using a percentage makes this adapt to the width of the window.  But
-	it won't work perfectly, because the actual number of characters
-	available also depends on the font used and other things in the title
-	bar.  When 'titlelen' is zero the full path is used.  Otherwise,
-	values from 1 to 30000 percent can be used.
-	'titlelen' is also used for the 'titlestring' option.
-
-						*'titleold'*
-'titleold'		string	(default "Thanks for flying Vim")
-			global
-	This option will be used for the window title when exiting Vim if the
-	original title cannot be restored.  Only happens if 'title' is on or
-	'titlestring' is not empty.
-	This option cannot be set from a |modeline| or in the |sandbox|, for
-	security reasons.
-						*'titlestring'*
-'titlestring'		string	(default "")
-			global
-	When this option is not empty, it will be used for the title of the
-	window.  This happens only when the 'title' option is on.
-	Only works if the terminal supports setting window titles (currently
-	Amiga console, Win32 console, all GUI versions and terminals with a
-	non-empty 't_ts' option).
-	When Vim was compiled with HAVE_X11 defined, the original title will
-	be restored if possible, see |X11|.
-
-	When this option contains printf-style '%' items, they will be
-	expanded according to the rules used for 'statusline'.
-	This option cannot be set in a modeline when 'modelineexpr' is off.
-
-	Example: >
-    :auto BufEnter * let &titlestring = hostname() .. "/" .. expand("%:p")
-    :set title titlestring=%<%F%=%l/%L-%P titlelen=70
-<	The value of 'titlelen' is used to align items in the middle or right
-	of the available space.
-	Some people prefer to have the file name first: >
-    :set titlestring=%t%(\ %M%)%(\ (%{expand(\"%:~:.:h\")})%)%(\ %a%)
-<	Note the use of "%{ }" and an expression to get the path of the file,
-	without the file name.  The "%( %)" constructs are used to add a
-	separating space only when needed.
-	NOTE: Use of special characters in 'titlestring' may cause the display
-	to be garbled (e.g., when it contains a CR or NL character).
-	{not available when compiled without the |+statusline| feature}
-
-				*'toolbar'* *'tb'*
-'toolbar' 'tb'		string	(default "icons,tooltips")
-			global
-			{only for |+GUI_GTK|, |+GUI_Motif| and |+GUI_Photon|}
-	The contents of this option controls various toolbar settings.  The
-	possible values are:
-		icons		Toolbar buttons are shown with icons.
-		text		Toolbar buttons shown with text.
-		horiz		Icon and text of a toolbar button are
-				horizontally arranged.  {only in GTK+ 2 GUI}
-		tooltips	Tooltips are active for toolbar buttons.
-	Tooltips refer to the popup help text which appears after the mouse
-	cursor is placed over a toolbar button for a brief moment.
-
-	If you want the toolbar to be shown with icons as well as text, do the
-	following: >
-		:set tb=icons,text
-<	Motif cannot display icons and text at the same time.  They
-	will show icons if both are requested.
-
-	If none of the strings specified in 'toolbar' are valid or if
-	'toolbar' is empty, this option is ignored.  If you want to disable
-	the toolbar, you need to set the 'guioptions' option.  For example: >
-		:set guioptions-=T
-<	Also see |gui-toolbar|.
-
-						*'toolbariconsize'* *'tbis'*
-'toolbariconsize' 'tbis'	string	(default "small")
-				global
-				{only in the GTK+ GUI}
-	Controls the size of toolbar icons.  The possible values are:
-		tiny		Use tiny icons.
-		small		Use small icons (default).
-		medium		Use medium-sized icons.
-		large		Use large icons.
-		huge		Use even larger icons.
-		giant		Use very big icons.
-	The exact dimensions in pixels of the various icon sizes depend on
-	the current theme.  Common dimensions are giant=48x48, huge=32x32,
-	large=24x24, medium=24x24, small=20x20 and tiny=16x16.
-
-	If 'toolbariconsize' is empty, the global default size as determined
-	by user preferences or the current theme is used.
-
-			     *'ttybuiltin'* *'tbi'* *'nottybuiltin'* *'notbi'*
-'ttybuiltin' 'tbi'	boolean	(default on)
-			global
-	When on, the builtin termcaps are searched before the external ones.
-	When off the builtin termcaps are searched after the external ones.
-	When this option is changed, you should set the 'term' option next for
-	the change to take effect, for example: >
-		:set notbi term=$TERM
-<	See also |termcap|.
-	Rationale: The default for this option is "on", because the builtin
-	termcap entries are generally better (many systems contain faulty
-	xterm entries...).
-
-				     *'ttyfast'* *'tf'* *'nottyfast'* *'notf'*
-'ttyfast' 'tf'		boolean	(default on)
-			global
-	Indicates a fast terminal connection.  More characters will be sent to
-	the screen for redrawing, instead of using insert/delete line
-	commands.  Improves smoothness of redrawing when there are multiple
-	windows and the terminal does not support a scrolling region.
-	Also enables the extra writing of characters at the end of each screen
-	line for lines that wrap.  This helps when using copy/paste with the
-	mouse in an xterm and other terminals.
-
-	The default used to be set only for some terminal names, but these
-	days nearly all terminals are fast, therefore the default is now "on".
-	If you have a slow connection you may want to set this option off,
-	e.g. depending on the host name: >
-		if hostname() =~ 'faraway'
-		   set nottyfast
-		endif
-<
-						*'ttymouse'* *'ttym'*
-'ttymouse' 'ttym'	string	(default depends on 'term')
-			global
-			{only in Unix and VMS, doesn't work in the GUI; not
-			available when compiled without |+mouse|}
-	Name of the terminal type for which mouse codes are to be recognized.
-	Currently these strings are valid:
-							*xterm-mouse*
-	   xterm	xterm-like mouse handling.  The mouse generates
-			"<Esc>[Mscr", where "scr" is three bytes:
-				"s"  = button state
-				"c"  = column plus 33
-				"r"  = row plus 33
-			This only works up to 223 columns!  See "dec",
-			"urxvt", and "sgr" for solutions.
-	   xterm2	Works like "xterm", but with the xterm reporting the
-			mouse position while the mouse is dragged.  This works
-			much faster and more precise.  Your xterm must at
-			least at patchlevel 88 / XFree 3.3.3 for this to
-			work.  See below for how Vim detects this
-			automatically.
-							*netterm-mouse*
-	   netterm	NetTerm mouse handling.  A left mouse click generates
-			"<Esc>}r,c<CR>", where "r,c" are two decimal numbers
-			for the row and column.  No other mouse events are
-			supported.
-							*dec-mouse*
-	   dec		DEC terminal mouse handling.  The mouse generates a
-			rather complex sequence, starting with "<Esc>[".
-			This is also available for an Xterm, if it was
-			configured with "--enable-dec-locator".
-							*jsbterm-mouse*
-	   jsbterm	JSB term mouse handling.
-							*pterm-mouse*
-	   pterm	QNX pterm mouse handling.
-							*urxvt-mouse*
-	   urxvt	Mouse handling for the urxvt (rxvt-unicode) terminal.
-			The mouse works only if the terminal supports this
-			encoding style, but it does not have 223 columns limit
-			unlike "xterm" or "xterm2".
-							*sgr-mouse*
-	   sgr		Mouse handling for the terminal that emits SGR-styled
-			mouse reporting.  The mouse works even in columns
-			beyond 223.  This option is backward compatible with
-			"xterm2" because it can also decode "xterm2" style
-			mouse codes.

-	|+mouse_sgr|.
-	Only "xterm"(2) is really recognized.  NetTerm mouse codes are always
-	recognized, if enabled at compile time.  DEC terminal mouse codes
-	are recognized if enabled at compile time, and 'ttymouse' is not
-	"xterm", "xterm2", "urxvt" or "sgr" (because dec mouse codes conflict
-	with them).
-	This option is automatically set to "xterm", when the 'term' option is
-	set to a name that starts with "xterm", "mlterm", "screen", "tmux",
-	"st" (full match only), "st-" or "stterm", and 'ttymouse' is not set
-	already.
-	If the terminfo/termcap entry "XM" exists and the first number is
-	"1006" then 'ttymouse' will be set to "sgr".  This works for many
-	modern terminals.
-	Additionally, if vim is compiled with the |+termresponse| feature and
-	|t_RV| is set to the escape sequence to request the xterm version
-	number, more intelligent detection is done.
-	The "xterm2" value will be set if the xterm version is reported to be
-	from 95 to 276.  The "sgr" value will be set if Vim detects Mac
-	Terminal.app, iTerm2 or mintty, and when the xterm version is 277 or
-	higher.
-	If you do not want 'ttymouse' to be set to "xterm2" or "sgr"

-						*'ttyscroll'* *'tsl'*
-'ttyscroll' 'tsl'	number	(default 999)
-			global
-	Maximum number of lines to scroll the screen.  If there are more lines
-	to scroll the window is redrawn.  For terminals where scrolling is
-	very slow and redrawing is not slow this can be set to a small number,
-	e.g., 3, to speed up displaying.

-			global
-			{only when compiled with the |+persistent_undo| feature}
-	List of directory names for undo files, separated with commas.
-	See |'backupdir'| for details of the format.
-	"." means using the directory of the file.  The undo file name for
-	"file.txt" is ".file.txt.un~".
-	For other directories the file name is the full path of the edited
-	file, with path separators replaced with "%".
-	When writing: The first directory that exists is used. "." always
-	works, no directories after "." will be used for writing.
-	When reading all entries are tried to find an undo file.  The first
-	undo file that exists is used.  When it cannot be read an error is
-	given, no further entry is used.
-	See |undo-persistence|.
-	This option cannot be set from a |modeline| or in the |sandbox|, for

-				*'undofile'* *'noundofile'* *'udf'* *'noudf'*
-'undofile' 'udf'	boolean	(default off)
-			local to buffer
-			{only when compiled with the |+persistent_undo| feature}
-	When on, Vim automatically saves undo history to an undo file when
-	writing a buffer to a file, and restores undo history from the same
-	file on buffer read.
-	The directory where the undo file is stored is specified by 'undodir'.
-	For more information about this feature see |undo-persistence|.
-	The undo file is not read when 'undoreload' causes the buffer from
-	before a reload to be saved for undo.
-	When 'undofile' is turned off the undo file is NOT deleted.
-	NOTE: This option is reset when 'compatible' is set.
-
-						*'undolevels'* *'ul'*
-'undolevels' 'ul'	number	(default 100, 1000 for Unix, VMS and Win32)
-			global or local to buffer |global-local|
-	Maximum number of changes that can be undone.  Since undo information
-	is kept in memory, higher numbers will cause more memory to be used.
-	Nevertheless, a single change can already use a large amount of memory.
-	Set to 0 for Vi compatibility: One level of undo and "u" undoes
-	itself: >
-		set ul=0
-<	But you can also get Vi compatibility by including the 'u' flag in
-	'cpoptions', and still be able to use CTRL-R to repeat undo.
-	Also see |undo-two-ways|.
-	Set to -1 for no undo at all.  You might want to do this only for the
-	current buffer: >
-		setlocal ul=-1
-<	This helps when you run out of memory for a single change.
-
-	The local value is set to -123456 when the global value is to be used.
-
-	Also see |clear-undo|.
-
-						*'undoreload'* *'ur'*
-'undoreload' 'ur'	number	(default 10000)
-			global
-	Save the whole buffer for undo when reloading it.  This applies to the
-	":e!" command and reloading for when the buffer changed outside of
-	Vim. |FileChangedShell|
-	The save only happens when this option is negative or when the number
-	of lines is smaller than the value of this option.
-	Set this option to zero to disable undo for a reload.
-
-	When saving undo for a reload, any undo file is not read.
-
-	Note that this causes the whole buffer to be stored in memory.  Set
-	this option to a lower value if you run out of memory.
-
-						*'updatecount'* *'uc'*
-'updatecount' 'uc'	number	(default: 200)
-			global
-	After typing this many characters the swap file will be written to
-	disk.  When zero, no swap file will be created at all (see chapter on
-	recovery |crash-recovery|).  'updatecount' is set to zero by starting
-	Vim with the "-n" option, see |startup|.  When editing in readonly
-	mode this option will be initialized to 10000.
-	The swapfile can be disabled per buffer with |'swapfile'|.
-	When 'updatecount' is set from zero to non-zero, swap files are
-	created for all buffers that have 'swapfile' set.  When 'updatecount'
-	is set to zero, existing swap files are not deleted.
-	Also see |'swapsync'|.
-	This option has no meaning in buffers where |'buftype'| is "nofile"
-	or "nowrite".
-
-						*'updatetime'* *'ut'*
-'updatetime' 'ut'	number	(default 4000)
-			global
-	If this many milliseconds nothing is typed the swap file will be

-					*'varsofttabstop'* *'vsts'*
-'varsofttabstop' 'vsts'	string	(default "")
-			local to buffer
-			{only available when compiled with the |+vartabs|
-			feature}
-	A list of the number of spaces that a <Tab> counts for while editing,
-	such as inserting a <Tab> or using <BS>.  It "feels" like variable-
-	width <Tab>s are being inserted, while in fact a mixture of spaces
-	and <Tab>s is used.  Tab widths are separated with commas, with the
-	final value applying to all subsequent tabs.
-
-	For example, when editing assembly language files where statements
-	start in the 9th column and comments in the 41st, it may be useful
-	to use the following: >
-		:set varsofttabstop=8,32,8
-<	This will set soft tabstops with 8 and 8 + 32 spaces, and 8 more
-	for every column thereafter.
-
-	Note that the value of |'softtabstop'| will be ignored while
-	'varsofttabstop' is set.
-
-						*'vartabstop'* *'vts'*
-'vartabstop' 'vts'	string	(default "")
-			local to buffer
-			{only available when compiled with the |+vartabs|
-			feature}
-	A list of the number of spaces that a <Tab> in the file counts for,
-	separated by commas.  Each value corresponds to one tab, with the
-	final value applying to all subsequent tabs. For example: >
-		:set vartabstop=4,20,10,8
-<	This will make the first tab 4 spaces wide, the second 20 spaces,
-	the third 10 spaces, and all following tabs 8 spaces.
-
-	Note that the value of |'tabstop'| will be ignored while 'vartabstop'
-	is set.
-
-						*'verbose'* *'vbs'*
-'verbose' 'vbs'		number	(default 0)
-			global
-	When bigger than zero, Vim will give messages about what it is doing.
-	Currently, these messages are given:
-	>= 1	When the viminfo file is read or written.
-	>= 2	When a file is ":source"'ed.
-	>= 4	Shell commands.
-	>= 5	Every searched tags file and include file.
-	>= 8	Files for which a group of autocommands is executed.
-	>= 9	Every executed autocommand.
-	>= 11	Finding items in a path
-	>= 12	Every executed function.
-	>= 13	When an exception is thrown, caught, finished, or discarded.
-	>= 14	Anything pending in a ":finally" clause.
-	>= 15	Every executed Ex command from a script (truncated at 200
-		characters).
-	>= 16	Every executed Ex command.
-
-	This option can also be set with the "-V" argument.  See |-V|.
-	This option is also set by the |:verbose| command.
-
-	When the 'verbosefile' option is set then the verbose messages are not
-	displayed.
-
-						*'verbosefile'* *'vfile'*
-'verbosefile' 'vfile'	string	(default empty)
-			global
-	When not empty all messages are written in a file with this name.
-	When the file exists messages are appended.
-	Writing to the file ends when Vim exits or when 'verbosefile' is made
-	empty.  Writes are buffered, thus may not show up for some time.
-	Setting 'verbosefile' to a new value is like making it empty first.
-	The difference with |:redir| is that verbose messages are not
-	displayed when 'verbosefile' is set.
-
-						*'viewdir'* *'vdir'*

-						*'viewoptions'* *'vop'*
-'viewoptions' 'vop'	string	(default: "folds,options,cursor,curdir")
-			global
-			{not available when compiled without the |+mksession|
-			feature}
-	Changes the effect of the |:mkview| command.  It is a comma-separated
-	list of words.  Each word enables saving and restoring something:
-	   word		save and restore ~
-	   cursor	cursor position in file and in window
-	   folds	manually created folds, opened/closed folds and local
-			fold options
-	   options	options and mappings local to a window or buffer (not
-			global values for local options)
-	   localoptions same as "options"
-	   slash	backslashes in file names replaced with forward
-			slashes
-	   unix		with Unix end-of-line format (single <NL>), even when
-			on MS-Windows
-	   curdir	the window-local directory, if set with `:lcd`
-
-	"slash" and "unix" are useful on MS-Windows when sharing view files
-	with Unix.  The Unix version of Vim cannot source dos format scripts,
-	but the MS-Windows version of Vim can source unix format scripts.

-			{not available when compiled without the |+viminfo|
-			feature}
-	When non-empty, the viminfo file is read upon startup and written
-	when exiting Vim (see |viminfo-file|). Except when 'viminfofile' is
-	"NONE".
-	The string should be a comma-separated list of parameters, each
-	consisting of a single character identifying the particular parameter,
-	followed by a number or string which specifies the value of that
-	parameter.  If a particular character is left out, then the default
-	value is used for that parameter.  The following is a list of the
-	identifying characters and the effect of their value.
-	CHAR	VALUE	~
-							*viminfo-!*
-	!	When included, save and restore global variables that start
-		with an uppercase letter, and don't contain a lowercase
-		letter.  Thus "KEEPTHIS and "K_L_M" are stored, but "KeepThis"
-		and "_K_L_M" are not.  Nested List and Dict items may not be
-		read back correctly, you end up with an empty item.
-							*viminfo-quote*
-	"	Maximum number of lines saved for each register.  Old name of
-		the '<' item, with the disadvantage that you need to put a
-		backslash before the ", otherwise it will be recognized as the
-		start of a comment!
-							*viminfo-%*
-	%	When included, save and restore the buffer list.  If Vim is
-		started with a file name argument, the buffer list is not
-		restored.  If Vim is started without a file name argument, the
-		buffer list is restored from the viminfo file.  Quickfix
-		('buftype'), unlisted ('buflisted'), unnamed and buffers on
-		removable media (|viminfo-r|) are not saved.
-		When followed by a number, the number specifies the maximum
-		number of buffers that are stored.  Without a number all
-		buffers are stored.
-							*viminfo-'*
-	'	Maximum number of previously edited files for which the marks
-		are remembered.  This parameter must always be included when
-		'viminfo' is non-empty.
-		Including this item also means that the |jumplist| and the
-		|changelist| are stored in the viminfo file.
-							*viminfo-/*
-	/	Maximum number of items in the search pattern history to be
-		saved.  If non-zero, then the previous search and substitute
-		patterns are also saved.  When not included, the value of
-		'history' is used.
-							*viminfo-:*
-	:	Maximum number of items in the command-line history to be
-		saved.  When not included, the value of 'history' is used.
-							*viminfo-<*
-	<	Maximum number of lines saved for each register.  If zero then
-		registers are not saved.  When not included, all lines are
-		saved.  '"' is the old name for this item.
-		Also see the 's' item below: limit specified in Kbyte.
-							*viminfo-@*
-	@	Maximum number of items in the input-line history to be
-		saved.  When not included, the value of 'history' is used.
-							*viminfo-c*
-	c	When included, convert the text in the viminfo file from the
-		'encoding' used when writing the file to the current
-		'encoding'.  See |viminfo-encoding|.
-							*viminfo-f*
-	f	Whether file marks need to be stored.  If zero, file marks ('0
-		to '9, 'A to 'Z) are not stored.  When not present or when
-		non-zero, they are all stored.  '0 is used for the current
-		cursor position (when exiting or when doing ":wviminfo").
-							*viminfo-h*
-	h	Disable the effect of 'hlsearch' when loading the viminfo
-		file.  When not included, it depends on whether ":nohlsearch"
-		has been used since the last search command.
-							*viminfo-n*
-	n	Name of the viminfo file.  The name must immediately follow
-		the 'n'.  Must be at the end of the option!  If the
-		'viminfofile' option is set, that file name overrides the one
-		given here with 'viminfo'.  Environment variables are
-		expanded when opening the file, not when setting the option.
-							*viminfo-r*
-	r	Removable media.  The argument is a string (up to the next
-		',').  This parameter can be given several times.  Each
-		specifies the start of a path for which no marks will be
-		stored.  This is to avoid removable media.  For MS-Windows you
-		could use "ra:,rb:", for Amiga "rdf0:,rdf1:,rdf2:".  You can
-		also use it for temp files, e.g., for Unix: "r/tmp".  Case is
-		ignored.  Maximum length of each 'r' argument is 50
-		characters.
-							*viminfo-s*
-	s	Maximum size of an item in Kbyte.  If zero then registers are
-		not saved.  Currently only applies to registers.  The default
-		"s10" will exclude registers with more than 10 Kbyte of text.
-		Also see the '<' item above: line count limit.
-
-	Example: >
-	    :set viminfo='50,<1000,s100,:0,n~/vim/viminfo
-<
-	'50		Marks will be remembered for the last 50 files you
-			edited.
-	<1000		Contents of registers (up to 1000 lines each) will be
-			remembered.
-	s100		Registers with more than 100 Kbyte text are skipped.
-	:0		Command-line history will not be saved.
-	n~/vim/viminfo	The name of the file to use is "~/vim/viminfo".
-	no /		Since '/' is not specified, the default will be used,
-			that is, save all of the search history, and also the
-			previous search and substitute patterns.
-	no %		The buffer list will not be saved nor read back.
-	no h		'hlsearch' highlighting will be restored.
-
-	When setting 'viminfo' from an empty value you can use |:rviminfo| to
-	load the contents of the file, this is not done automatically.
-
-	This option cannot be set from a |modeline| or in the |sandbox|, for
-	security reasons.
-	NOTE: This option is set to the Vim default value when 'compatible'
-	is reset.
-
-				*'viminfofile'* *'vif'*
-'viminfofile' 'vif'	string	(default: "")
-			global
-			{not available when compiled without the |+viminfo|
-			feature}
-	When non-empty, overrides the file name used for viminfo.
-	When equal to "NONE" no viminfo file will be read or written.
-	This option can be set with the |-i| command line flag.  The |--clean|
-	command line flag sets it to "NONE".
-	This option cannot be set from a |modeline| or in the |sandbox|, for
-	security reasons.
-
-					    *'virtualedit'* *'ve'*
-'virtualedit' 've'	string	(default "")
-			global or local to window |global-local|
-	A comma-separated list of these words:
-	    block	Allow virtual editing in Visual block mode.
-	    insert	Allow virtual editing in Insert mode.
-	    all		Allow virtual editing in all modes.
-	    onemore	Allow the cursor to move just past the end of the line
-	    none	When used as the local value, do not allow virtual
-			editing even when the global value is set.  When used
-			as the global value, "none" is the same as "".
-	    NONE	Alternative spelling of "none".
-
-	Virtual editing means that the cursor can be positioned where there is
-	no actual character.  This can be halfway into a tab or beyond the end
-	of the line.  Useful for selecting a rectangle in Visual mode and
-	editing a table.
-	"onemore" is not the same, it will only allow moving the cursor just
-	after the last character of the line.  This makes some commands more
-	consistent.  Previously the cursor was always past the end of the line
-	if the line was empty.  But it is far from Vi compatible.  It may also
-	break some plugins or Vim scripts.  For example because |l| can move
-	the cursor after the last character.  Use with care!
-	Using the `$` command will move to the last character in the line, not
-	past it.  This may actually move the cursor to the left!
-	The `g$` command will move to the end of the screen line.
-	It doesn't make sense to combine "all" with "onemore", but you will
-	not get a warning for it.
-	When combined with other words, "none" is ignored.
-	NOTE: This option is set to "" when 'compatible' is set.
-
-			*'visualbell'* *'vb'* *'novisualbell'* *'novb'* *beep*
-'visualbell' 'vb'	boolean	(default off)
-			global
-	Use a visual bell instead of beeping.  The terminal code to display the
-	visual bell is given with 't_vb'.  When no beep or flash is wanted,
-	use: >
-		:set vb t_vb=
-<	If you want a short flash, you can use this on many terminals: >
-		:set vb t_vb=[?5h$<100>[?5l
-<	Here $<100> specifies the time, you can use a smaller or bigger value
-	to get a shorter or longer flash.
-
-	Note: Vim will limit the bell to once per half a second.  This avoids
-	having to wait for the flashing to finish when there are lots of
-	bells, e.g. on key repeat.  This also happens without 'visualbell'
-	set.
-
-	In the GUI, 't_vb' defaults to "<Esc>|f", which inverts the display
-	for 20 msec.  If you want to use a different time, use "<Esc>|40f",
-	where 40 is the time in msec.
-
-	Note: When the GUI starts, 't_vb' is reset to its default value.  You
-	might want to set it again in your |gvimrc|.
-
-	Does not work on the Amiga, you always get a screen flash.
-	Also see 'errorbells'.
-
-						*'warn'* *'nowarn'*
-'warn'			boolean	(default on)
-			global
-	Give a warning message when a shell command is used while the buffer
-	has been changed.
-
-		     *'weirdinvert'* *'wiv'* *'noweirdinvert'* *'nowiv'*
-'weirdinvert' 'wiv'	boolean	(default off)
-			global
-	This option has the same effect as the 't_xs' terminal option.
-	It is provided for backwards compatibility with version 4.x.
-	Setting 'weirdinvert' has the effect of making 't_xs' non-empty, and
-	vice versa.  Has no effect when the GUI is running.
-
-						*'whichwrap'* *'ww'*
-'whichwrap' 'ww'	string	(Vim default: "b,s", Vi default: "")
-			global
-	Allow specified keys that move the cursor left/right to move to the
-	previous/next line when the cursor is on the first/last character in
-	the line.  Concatenate characters to allow this for these keys:
-		char   key	  mode	~
-		 b    <BS>	 Normal and Visual
-		 s    <Space>	 Normal and Visual
-		 h    "h"	 Normal and Visual (not recommended)
-		 l    "l"	 Normal and Visual (not recommended)
-		 <    <Left>	 Normal and Visual
-		 >    <Right>	 Normal and Visual
-		 ~    "~"	 Normal
-		 [    <Left>	 Insert and Replace
-		 ]    <Right>	 Insert and Replace
-	For example: >
-		:set ww=<,>,[,]
-<	allows wrap only when cursor keys are used.
-	When the movement keys are used in combination with a delete or change
-	operator, the <EOL> also counts for a character.  This makes "3h"
-	different from "3dh" when the cursor crosses the end of a line.  This
-	is also true for "x" and "X", because they do the same as "dl" and
-	"dh".  If you use this, you may also want to use the mapping
-	":map <BS> X" to make backspace delete the character in front of the
-	cursor.
-	When 'l' is included and it is used after an operator at the end of a
-	line (not an empty line) then it will not move to the next line.  This
-	makes "dl", "cl", "yl" etc. work normally.
-	NOTE: This option is set to the Vi default value when 'compatible' is
-	set and to the Vim default value when 'compatible' is reset.
-
-						*'wildchar'* *'wc'*
-'wildchar' 'wc'		number	(Vim default: <Tab>, Vi default: CTRL-E)
-			global
-	Character you have to type to start wildcard expansion in the
-	command-line, as specified with 'wildmode'.
-	More info here: |cmdline-completion|.
-	The character is not recognized when used inside a macro.  See
-	'wildcharm' for that.
-	Some keys will not work, such as CTRL-C, <CR> and Enter.
-	Although 'wc' is a number option, you can set it to a special key: >
-		:set wc=<Tab>
-<	NOTE: This option is set to the Vi default value when 'compatible' is
-	set and to the Vim default value when 'compatible' is reset.
-
-						*'wildcharm'* *'wcm'*
-'wildcharm' 'wcm'	number	(default: none (0))
-			global
-	'wildcharm' works exactly like 'wildchar', except that it is
-	recognized when used inside a macro.  You can find "spare" command-line
-	keys suitable for this option by looking at |ex-edit-index|.  Normally
-	you'll never actually type 'wildcharm', just use it in mappings that
-	automatically invoke completion mode, e.g.: >
-		:set wcm=<C-Z>
-		:cnoremap ss so $vim/sessions/*.vim<C-Z>
-<	Then after typing :ss you can use CTRL-P & CTRL-N.
-
-						*'wildignore'* *'wig'*
-'wildignore' 'wig'	string	(default "")
-			global
-	A list of file patterns.  A file that matches with one of these
-	patterns is ignored when expanding |wildcards|, completing file or
-	directory names, and influences the result of |expand()|, |glob()| and
-	|globpath()| unless a flag is passed to disable this.
-	The pattern is used like with |:autocmd|, see |autocmd-patterns|.
-	Also see 'suffixes'.
-	Example: >
-		:set wildignore=*.o,*.obj
-<	The use of |:set+=| and |:set-=| is preferred when adding or removing
-	a pattern from the list.  This avoids problems when a future version
-	uses another default.
-
-
-			*'wildignorecase'* *'wic'* *'nowildignorecase'* *'nowic'*
-'wildignorecase' 'wic'	boolean	(default off)
-			global
-	When set case is ignored when completing file names and directories.
-	Has no effect when 'fileignorecase' is set.
-	Does not apply when the shell is used to expand wildcards, which
-	happens when there are special characters.
-
-
-				*'wildmenu'* *'wmnu'* *'nowildmenu'* *'nowmnu'*
-'wildmenu' 'wmnu'	boolean	(default off, set in |defaults.vim|)
-			global
-	When 'wildmenu' is on, command-line completion operates in an enhanced
-	mode.  On pressing 'wildchar' (usually <Tab>) to invoke completion,
-	the possible matches are shown.
-	When 'wildoptions' contains "pum", then the completion matches are
-	shown in a popup menu.  Otherwise they are displayed just above the
-	command line, with the first match highlighted (overwriting the status
-	line, if there is one).
-	Keys that show the previous/next match, such as <Tab> or
-	CTRL-P/CTRL-N, cause the highlight to move to the appropriate match.
-	When 'wildmode' is used, "wildmenu" mode is used where "full" is
-	specified.  "longest" and "list" do not start "wildmenu" mode.
-	You can check the current mode with |wildmenumode()|.
-	If there are more matches than can fit in the line, a ">" is shown on
-	the right and/or a "<" is shown on the left.  The status line scrolls
-	as needed.
-	The "wildmenu" mode is abandoned when a key is hit that is not used
-	for selecting a completion.
-	While the "wildmenu" is active, not using the popup menu, the
-	following keys have special meanings:
-
-	<Left> <Right>	- select previous/next match (like CTRL-P/CTRL-N)
-	<Down>		- in filename/menu name completion: move into a
-			  subdirectory or submenu.
-	<CR>		- in menu completion, when the cursor is just after a
-			  dot: move into a submenu.
-	<Up>		- in filename/menu name completion: move up into
-			  parent directory or parent menu.
-
-	When using the popup menu for command line completion, the following
-	keys have special meanings:
-	<Down>		- select next match (like CTRL-N)
-	<Left>		- in filename/menu name completion: move up into
-			  parent directory or parent menu.
-	<Right>		- in filename/menu name completion: move into a
-			  subdirectory or submenu.
-	<Up>		- select previous match (like CTRL-P)
-	CTRL-E		- end completion, go back to what was there before
-			  selecting a match.
-	CTRL-N		- go to the next entry
-	CTRL-P		- go to the previous entry
-	CTRL-Y		- accept the currently selected match and stop
-			  completion.
-
-	This makes the menus accessible from the console |console-menus|.
-
-	If you prefer the <Left> and <Right> keys to move the cursor instead
-	of selecting a different match, use this: >
-		:cnoremap <Left> <Space><BS><Left>
-		:cnoremap <Right> <Space><BS><Right>
-<
-	The "WildMenu" highlighting is used for displaying the current match
-	|hl-WildMenu|.
-
-						*'wildmode'* *'wim'*
-'wildmode' 'wim'	string	(Vim default: "full")
-			global
-	Completion mode that is used for the character specified with
-	'wildchar'.  It is a comma-separated list of up to four parts.  Each
-	part specifies what to do for each consecutive use of 'wildchar'.  The
-	first part specifies the behavior for the first use of 'wildchar',
-	The second part for the second use, etc.
-
-	Each part consists of a colon separated list consisting of the
-	following possible values:
-	""		Complete only the first match.
-	"full"		Complete the next full match.  After the last match,
-			the original string is used and then the first match
-			again.  Will also start 'wildmenu' if it is enabled.
-	"longest"	Complete till longest common string.  If this doesn't
-			result in a longer string, use the next part.
-	"list"		When more than one match, list all matches.
-	"lastused"	When completing buffer names and more than one buffer
-			matches, sort buffers by time last used (other than
-			the current buffer).
-	When there is only a single match, it is fully completed in all cases.
-
-	Examples of useful colon-separated values:
-	"longest:full"	Like "longest", but also start 'wildmenu' if it is
-			enabled.  Will not complete to the next full match.
-	"list:full"	When more than one match, list all matches and
-			complete first match.
-	"list:longest"	When more than one match, list all matches and
-			complete till longest common string.
-	"list:lastused" When more than one buffer matches, list all matches
-			and sort buffers by time last used (other than the
-			current buffer).
-
-	Examples: >
-		:set wildmode=full
-<	Complete first full match, next match, etc.  (the default) >
-		:set wildmode=longest,full
-<	Complete longest common string, then each full match >
-		:set wildmode=list:full
-<	List all matches and complete each full match >
-		:set wildmode=list,full
-<	List all matches without completing, then each full match >
-		:set wildmode=longest,list
-<	Complete longest common string, then list alternatives.
-	More info here: |cmdline-completion|.
-
-						*'wildoptions'* *'wop'*
-'wildoptions' 'wop'	string	(default "")
-			global
-	A list of words that change how |cmdline-completion| is done.
-	The following values are supported:
-	  fuzzy		Use |fuzzy-matching| to find completion matches. When
-			this value is specified, wildcard expansion will not
-			be used for completion.  The matches will be sorted by
-			the "best match" rather than alphabetically sorted.
-			This will find more matches than the wildcard
-			expansion. Currently fuzzy matching based completion
-			is not supported for file and directory names and
-			instead wildcard expansion is used.
-	  pum		Display the completion matches using the popup menu
-			in the same style as the |ins-completion-menu|.
-	  tagfile	When using CTRL-D to list matching tags, the kind of
-			tag and the file of the tag is listed.	Only one match
-			is displayed per line.  Often used tag kinds are:
-				d	#define
-				f	function
-
-						*'winaltkeys'* *'wak'*
-'winaltkeys' 'wak'	string	(default "menu")
-			global
-			{only used in Win32, Motif, GTK and Photon GUI}
-	Some GUI versions allow the access to menu entries by using the ALT
-	key in combination with a character that appears underlined in the
-	menu.  This conflicts with the use of the ALT key for mappings and
-	entering special characters.  This option tells what to do:
-	  no	Don't use ALT keys for menus.  ALT key combinations can be
-		mapped, but there is no automatic handling.  This can then be
-		done with the |:simalt| command.
-	  yes	ALT key handling is done by the windowing system.  ALT key
-		combinations cannot be mapped.
-	  menu	Using ALT in combination with a character that is a menu
-		shortcut key, will be handled by the windowing system.  Other
-		keys can be mapped.
-	If the menu is disabled by excluding 'm' from 'guioptions', the ALT
-	key is never used for the menu.
-	This option is not used for <F10>; on Win32 and with GTK <F10> will
-	select the menu, unless it has been mapped.
-
-						*'wincolor'* *'wcr'*
-'wincolor' 'wcr' string (default empty)
-			local to window
-	Highlight group name to use for this window instead of the Normal
-	color |hl-Normal|.
-
-						*'window'* *'wi'*
-'window' 'wi'		number  (default screen height - 1)
-			global
-	Window height used for |CTRL-F| and |CTRL-B| when there is only one
-	window and the value is smaller than 'lines' minus one.  The screen
-	will scroll 'window' minus two lines, with a minimum of one.
-	When 'window' is equal to 'lines' minus one CTRL-F and CTRL-B scroll
-	in a much smarter way, taking care of wrapping lines.
-	When resizing the Vim window, the value is smaller than 1 or more than
-	or equal to 'lines' it will be set to 'lines' minus 1.
-	Note: Do not confuse this with the height of the Vim window, use
-	'lines' for that.
-
-						*'winheight'* *'wh'* *E591*
-'winheight' 'wh'	number	(default 1)
-			global
-	Minimal number of lines for the current window.  This is not a hard
-	minimum, Vim will use fewer lines if there is not enough room.  If the
-	focus goes to a window that is smaller, its size is increased, at the
-	cost of the height of other windows.
-	Set 'winheight' to a small number for normal editing.
-	Set it to 999 to make the current window fill most of the screen.
-	Other windows will be only 'winminheight' high.  This has the drawback
-	that ":all" will create only two windows.  To avoid "vim -o 1 2 3 4"
-	to create only two windows, set the option after startup is done,
-	using the |VimEnter| event: >
-		au VimEnter * set winheight=999
-<	Minimum value is 1.
-	The height is not adjusted after one of the commands that change the
-	height of the current window.
-	'winheight' applies to the current window.  Use 'winminheight' to set
-	the minimal height for other windows.
-
-			*'winfixheight'* *'wfh'* *'nowinfixheight'* *'nowfh'*
-'winfixheight' 'wfh'	boolean	(default off)
-			local to window
-	Keep the window height when windows are opened or closed and
-	'equalalways' is set.  Also for |CTRL-W_=|.  Set by default for the
-	|preview-window| and |quickfix-window|.
-	The height may be changed anyway when running out of room.
-
-			*'winfixwidth'* *'wfw'* *'nowinfixwidth'* *'nowfw'*
-'winfixwidth' 'wfw'	boolean	(default off)
-			local to window
-	Keep the window width when windows are opened or closed and
-	'equalalways' is set.  Also for |CTRL-W_=|.
-	The width may be changed anyway when running out of room.
-
-						*'winminheight'* *'wmh'*
-'winminheight' 'wmh'	number	(default 1)
-			global
-	The minimal height of a window, when it's not the current window.
-	This is a hard minimum, windows will never become smaller.
-	When set to zero, windows may be "squashed" to zero lines (i.e. just a
-	status bar) if necessary.  They will return to at least one line when
-	they become active (since the cursor has to have somewhere to go.)
-	Use 'winheight' to set the minimal height of the current window.
-	This option is only checked when making a window smaller.  Don't use a
-	large number, it will cause errors when opening more than a few
-	windows.  A value of 0 to 3 is reasonable.
-
-						*'winminwidth'* *'wmw'*
-'winminwidth' 'wmw'	number	(default 1)
-			global
-	The minimal width of a window, when it's not the current window.
-	This is a hard minimum, windows will never become smaller.
-	When set to zero, windows may be "squashed" to zero columns (i.e. just
-	a vertical separator) if necessary.  They will return to at least one
-	line when they become active (since the cursor has to have somewhere
-	to go.)
-	Use 'winwidth' to set the minimal width of the current window.
-	This option is only checked when making a window smaller.  Don't use a
-	large number, it will cause errors when opening more than a few
-	windows.  A value of 0 to 12 is reasonable.
-
-						*'winptydll'*
-'winptydll'		string	(default "winpty32.dll" or "winpty64.dll")
-			global
-			{only available when compiled with the |terminal|
-			feature on MS-Windows}
-	Specifies the name of the winpty shared library, used for the
-	|:terminal| command. The default depends on whether Vim was built as a
-	32-bit or 64-bit executable.  If not found, "winpty.dll" is tried as
-	a fallback.
-	Environment variables are expanded |:set_env|.
-	This option cannot be set from a |modeline| or in the |sandbox|, for
-	security reasons.
-
-						*'winwidth'* *'wiw'* *E592*
-'winwidth' 'wiw'	number	(default 20)
-			global
-	Minimal number of columns for the current window.  This is not a hard
-	minimum, Vim will use fewer columns if there is not enough room.  If
-	the current window is smaller, its size is increased, at the cost of
-	the width of other windows.  Set it to 999 to make the current window
-	always fill the screen.  Set it to a small number for normal editing.
-	The width is not adjusted after one of the commands to change the
-	width of the current window.
-	'winwidth' applies to the current window.  Use 'winminwidth' to set
-	the minimal width for other windows.
-
-						*'wrap'* *'nowrap'*
-'wrap'			boolean	(default on)
-			local to window
-	This option changes how text is displayed.  It doesn't change the text
-	in the buffer, see 'textwidth' for that.
-	When on, lines longer than the width of the window will wrap and
-	displaying continues on the next line.  When off lines will not wrap
-	and only part of long lines will be displayed.  When the cursor is
-	moved to a part that is not shown, the screen will scroll
-	horizontally.
-	The line will be broken in the middle of a word if necessary.  See
-	'linebreak' to get the break at a word boundary.
-	To make scrolling horizontally a bit more useful, try this: >
-		:set sidescroll=5
-		:set listchars+=precedes:<,extends:>
-<	See 'sidescroll', 'listchars' and |wrap-off|.
-	This option can't be set from a |modeline| when the 'diff' option is
-	on.
-
-						*'wrapmargin'* *'wm'*
-'wrapmargin' 'wm'	number	(default 0)
-			local to buffer
-	Number of characters from the right window border where wrapping
-	starts.  When typing text beyond this limit, an <EOL> will be inserted
-	and inserting continues on the next line.
-	Options that add a margin, such as 'number' and 'foldcolumn', cause
-	the text width to be further reduced.  This is Vi compatible.
-	When 'textwidth' is non-zero, this option is not used.
-	This option is set to 0 when 'paste' is set and restored when 'paste'
-	is reset.
-	See also 'formatoptions' and |ins-textwidth|.
-
-				   *'wrapscan'* *'ws'* *'nowrapscan'* *'nows'*
-'wrapscan' 'ws'		boolean	(default on)			*E384* *E385*
-			global
-	Searches wrap around the end of the file.  Also applies to |]s| and
-	|[s|, searching for spelling mistakes.
-
-						   *'write'* *'nowrite'*
-'write'			boolean	(default on)
-			global
-	Allows writing files.  When not set, writing a file is not allowed.
-	Can be used for a view-only mode, where modifications to the text are
-	still allowed.  Can be reset with the |-m| or |-M| command line
-	argument.  Filtering text is still possible, even though this requires
-	writing a temporary file.
-
-				   *'writeany'* *'wa'* *'nowriteany'* *'nowa'*
-'writeany' 'wa'		boolean	(default off)
-			global
-	Allows writing to any file with no need for "!" override.
-
-			     *'writebackup'* *'wb'* *'nowritebackup'* *'nowb'*
-'writebackup' 'wb'	boolean	(default on with |+writebackup| feature, off
-					otherwise)
-			global
-	Make a backup before overwriting a file.  The backup is removed after
-	the file was successfully written, unless the 'backup' option is
-	also on.
-	WARNING: Switching this option off means that when Vim fails to write
-	your buffer correctly and then, for whatever reason, Vim exits, you
-	lose both the original file and what you were writing.  Only reset
-	this option if your file system is almost full and it makes the write
-	fail (and make sure not to exit Vim until the write was successful).
-	See |backup-table| for another explanation.
-	When the 'backupskip' pattern matches, a backup is not made anyway.
-	Depending on 'backupcopy' the backup is a new file or the original
-	file renamed (and a new file is written).
-	NOTE: This option is set to the default value when 'compatible' is
-	set.
-
-						*'writedelay'* *'wd'*
-'writedelay' 'wd'	number	(default 0)
-			global
-	The number of milliseconds to wait for each character sent to the
-	screen.  When non-zero, characters are sent to the terminal one by
-	one.  For debugging purposes.
-
-					   *'xtermcodes'* *'noxtermcodes'*
-'xtermcodes'		boolean	(default on)
-			global
-	When detecting xterm patchlevel 141 or higher with the termresponse
-	mechanism and this option is set, Vim will request the actual terminal
-	key codes and number of colors from the terminal.  This takes care of
-	various configuration options of the terminal that cannot be obtained
-	from the termlib/terminfo entry, see |xterm-codes|.
-	A side effect may be that t_Co changes and Vim will redraw the
-	display.

+		  VIM REFERENCE MANUAL	  by Bram Moolenaar
+
+
+Options							*options*
+
+1. Setting options			|set-option|
+2. Automatically setting options	|auto-setting|
+3. Options summary			|option-summary|
+
+For an overview of options see quickref.txt |option-list|.
+
+Vim has a number of internal variables and switches which can be set to
+achieve special effects.  These options come in three forms:
+	boolean		can only be on or off		*boolean* *toggle*
+	number		has a numeric value
+	string		has a string value
+
+==============================================================================
+1. Setting options					*set-option* *E764*
+
+							*:se* *:set*
+:se[t][!]		Show all options that differ from their default value.
+			When [!] is present every option is on a separate
+			line.
+
+:se[t][!] all		Show all but terminal options.
+			When [!] is present every option is on a separate
+			line.
+
+:se[t] termcap		Show all terminal options.  Note that in the GUI the
+			key codes are not shown, because they are generated
+			internally and can't be changed.  Changing the terminal
+			codes in the GUI is not useful either...
+			The options have the form t_AB, see
+			|terminal-options|.
+
+:se[t]! termcap		Idem, but don't use multiple columns.
+
+								*E518* *E519*
+:se[t] {option}?	Show value of {option}.
+
+:se[t] {option}		Toggle option: set, switch it on.
+			Number option: show value.
+			String option: show value.
+
+:se[t] no{option}	Toggle option: Reset, switch it off.
+
+							   *:set-!* *:set-inv*
+:se[t] {option}!   or
+:se[t] inv{option}	Toggle option: Invert value.
+
+				*:set-default* *:set-&* *:set-&vi* *:set-&vim*
+:se[t] {option}&	Reset option to its default value.  May depend on the
+			current value of 'compatible'.
+:se[t] {option}&vi	Reset option to its Vi default value.
+:se[t] {option}&vim	Reset option to its Vim default value.
+
+:se[t] all&		Set all options to their default value.  The values of
+			these options are not changed:
+			  all terminal options, starting with t_
+			  'columns'
+			  'cryptmethod'
+			  'encoding'
+			  'key'
+			  'lines'
+			  'term'
+			  'ttymouse'
+			  'ttytype'
+			Warning: This may have a lot of side effects.
+
+						*:set-args* *E487* *E521*
+:se[t] {option}={value}		or
+:se[t] {option}:{value}
+			Set string or number option to {value}.
+			For numeric options the value can be given in decimal,
+			hex (preceded with 0x) or octal (preceded with '0').
+			The old value can be inserted by typing 'wildchar' (by
+			default this is a <Tab> or CTRL-E if 'compatible' is
+			set).  See |cmdline-completion|.
+			White space between {option} and '=' is allowed and
+			will be ignored.  White space between '=' and {value}
+			is not allowed.
+			See |option-backslash| for using white space and
+			backslashes in {value}.
+
+:se[t] {option}+={value}				*:set+=*
+			Add the {value} to a number option, or append the
+			{value} to a string option.  When the option is a
+			comma-separated list, a comma is added, unless the
+			value was empty.
+			If the option is a list of flags, superfluous flags
+			are removed.  When adding a flag that was already
+			present the option value doesn't change.
+			Also see |:set-args| above.
+
+:se[t] {option}^={value}				*:set^=*
+			Multiply the {value} to a number option, or prepend
+			the {value} to a string option.  When the option is a
+			comma-separated list, a comma is added, unless the
+			value was empty.
+			Also see |:set-args| above.
+
+:se[t] {option}-={value}				*:set-=*
+			Subtract the {value} from a number option, or remove
+			the {value} from a string option, if it is there.
+			If the {value} is not found in a string option, there
+			is no error or warning.  When the option is a comma
+			separated list, a comma is deleted, unless the option
+			becomes empty.
+			When the option is a list of flags, {value} must be
+			exactly as they appear in the option.  Remove flags
+			one by one to avoid problems.
+			Also see |:set-args| above.
+
+The {option} arguments to ":set" may be repeated.  For example: >
+	:set ai nosi sw=3 ts=3
+If you make an error in one of the arguments, an error message will be given
+and the following arguments will be ignored.
+
+							*:set-verbose*
+When 'verbose' is non-zero, displaying an option value will also tell where it
+was last set.  Example: >
+	:verbose set shiftwidth cindent?
+<  shiftwidth=4 ~
+	  Last set from modeline line 1 ~
+  cindent ~
+	  Last set from /usr/local/share/vim/vim60/ftplugin/c.vim line 30 ~
+This is only done when specific option values are requested, not for ":verbose
+set all" or ":verbose set" without an argument.
+When the option was set by hand there is no "Last set" message.
+When the option was set while executing a function, user command or
+autocommand, the script in which it was defined is reported.
+Note that an option may also have been set as a side effect of setting
+'compatible'.
+A few special texts:
+	Last set from modeline line 1 ~
+		Option was set in a |modeline|.
+	Last set from --cmd argument ~
+		Option was set with command line argument |--cmd| or +.
+	Last set from -c argument ~
+		Option was set with command line argument |-c|, +, |-S| or
+		|-q|.
+	Last set from environment variable ~
+		Option was set from an environment variable, $VIMINIT,
+		$GVIMINIT or $EXINIT.
+	Last set from error handler ~
+		Option was cleared when evaluating it resulted in an error.
+
+{not available when compiled without the |+eval| feature}
+
+							*:set-termcap* *E522*
+For {option} the form "t_xx" may be used to set a terminal option.  This will
+override the value from the termcap.  You can then use it in a mapping.  If
+the "xx" part contains special characters, use the <t_xx> form: >
+	:set <t_#4>=^[Ot
+This can also be used to translate a special code for a normal key.  For
+example, if Alt-b produces <Esc>b, use this: >
+	:set <M-b>=^[b
+(the ^[ is a real <Esc> here, use CTRL-V <Esc> to enter it)
+The advantage over a mapping is that it works in all situations.
+
+You can define any key codes, e.g.: >
+	:set t_xy=^[foo;
+There is no warning for using a name that isn't recognized.  You can map these
+codes as you like: >
+	:map <t_xy> something
+<								*E846*
+When a key code is not set, it's like it does not exist.  Trying to get its
+value will result in an error: >
+	:set t_kb=
+	:set t_kb
+<	E846: Key code not set: t_kb ~
+
+The t_xx options cannot be set from a |modeline| or in the |sandbox|, for
+security reasons.
+
+The listing from ":set" looks different from Vi.  Long string options are put
+at the end of the list.  The number of options is quite large.  The output of
+"set all" probably does not fit on the screen, causing Vim to give the
+|more-prompt|.
+
+							*option-backslash*
+To include white space in a string option value it has to be preceded with a
+backslash.  To include a backslash you have to use two.  Effectively this
+means that the number of backslashes in an option value is halved (rounded
+down).
+A few examples: >
+   :set tags=tags\ /usr/tags	    results in "tags /usr/tags"
+   :set tags=tags\\,file	    results in "tags\,file"
+   :set tags=tags\\\ file	    results in "tags\ file"
+
+The "|" character separates a ":set" command from a following command.  To
+include the "|" in the option value, use "\|" instead.  This example sets the
+'titlestring' option to "hi|there": >
+   :set titlestring=hi\|there
+This sets the 'titlestring' option to "hi" and 'iconstring' to "there": >
+   :set titlestring=hi|set iconstring=there
+
+Similarly, in legacy script the double quote character starts a comment.  To
+include the '"' in the option value, use '\"' instead.  This example sets the
+'titlestring' option to 'hi "there"': >
+   :set titlestring=hi\ \"there\"
+
+In |Vim9| script it's simpler, comments start with a '#' character, and only
+when preceded by white space.  A backslash is needed less often: >
+   vim9script
+   set titlestring=hi\ "there"
+   set titlestring=hi#there#
+   set titlestring=hi\ \#there#
+
+For Win32 backslashes in file names are mostly not removed.  More precise: For
+options that expect a file name (those where environment variables are
+expanded) a backslash before a normal file name character is not removed.  But
+a backslash before a special character (space, backslash, comma, etc.) is used
+like explained above.
+There is one special situation, when the value starts with "\\": >
+   :set dir=\\machine\path	    results in "\\machine\path"
+   :set dir=\\\\machine\\path	    results in "\\machine\path"
+   :set dir=\\path\\file	    results in "\\path\file" (wrong!)
+For the first one the start is kept, but for the second one the backslashes
+are halved.  This makes sure it works both when you expect backslashes to be
+halved and when you expect the backslashes to be kept.  The third gives a
+result which is probably not what you want.  Avoid it.
+
+				*add-option-flags* *remove-option-flags*
+				*E539* *E550* *E551* *E552*
+Some options are a list of flags.  When you want to add a flag to such an
+option, without changing the existing ones, you can do it like this: >
+   :set guioptions+=a
+Remove a flag from an option like this: >
+   :set guioptions-=a
+This removes the 'a' flag from 'guioptions'.
+Note that you should add or remove one flag at a time.  If 'guioptions' has
+the value "ab", using "set guioptions-=ba" won't work, because the string "ba"
+doesn't appear.
+
+			   *:set_env* *expand-env* *expand-environment-var*
+Environment variables in specific string options will be expanded.  If the
+environment variable exists the '$' and the following environment variable
+name is replaced with its value.  If it does not exist the '$' and the name
+are not modified.  Any non-id character (not a letter, digit or '_') may
+follow the environment variable name.  That character and what follows is
+appended to the value of the environment variable.  Examples: >
+   :set term=$TERM.new
+   :set path=/usr/$INCLUDE,$HOME/include,.
+When adding or removing a string from an option with ":set opt-=val" or ":set
+opt+=val" the expansion is done before the adding or removing.
+
+
+Handling of local options			*local-options*
+
+Some of the options only apply to a window or buffer.  Each window or buffer
+has its own copy of this option, thus each can have its own value.  This
+allows you to set 'list' in one window but not in another.  And set
+'shiftwidth' to 3 in one buffer and 4 in another.
+
+The following explains what happens to these local options in specific
+situations.  You don't really need to know all of this, since Vim mostly uses
+the option values you would expect.  Unfortunately, doing what the user
+expects is a bit complicated...
+
+When splitting a window, the local options are copied to the new window.  Thus
+right after the split the contents of the two windows look the same.
+
+When editing a new buffer, its local option values must be initialized.  Since
+the local options of the current buffer might be specifically for that buffer,
+these are not used.  Instead, for each buffer-local option there also is a
+global value, which is used for new buffers.  With ":set" both the local and
+global value is changed.  With "setlocal" only the local value is changed,
+thus this value is not used when editing a new buffer.
+
+When editing a buffer that has been edited before, the options from the window
+that was last closed are used again.  If this buffer has been edited in this
+window, the values from back then are used.  Otherwise the values from the
+last closed window where the buffer was edited last are used.
+
+It's possible to set a local window option specifically for a type of buffer.
+When you edit another buffer in the same window, you don't want to keep
+using these local window options.  Therefore Vim keeps a global value of the
+local window options, which is used when editing another buffer.  Each window
+has its own copy of these values.  Thus these are local to the window, but
+global to all buffers in the window.  With this you can do: >
+	:e one
+	:set list
+	:e two
+Now the 'list' option will also be set in "two", since with the ":set list"
+command you have also set the global value. >
+	:set nolist
+	:e one
+	:setlocal list
+	:e two
+Now the 'list' option is not set, because ":set nolist" resets the global
+value, ":setlocal list" only changes the local value and ":e two" gets the
+global value.  Note that if you do this next: >
+	:e one
+You will get back the 'list' value as it was the last time you edited "one".
+The options local to a window are remembered for each buffer.  This also
+happens when the buffer is not loaded, but they are lost when the buffer is
+wiped out |:bwipe|.
+
+							*:setl* *:setlocal*
+:setl[ocal][!] ...	Like ":set" but set only the value local to the
+			current buffer or window.  Not all options have a
+			local value.  If the option does not have a local
+			value the global value is set.
+			With the "all" argument: display local values for all
+			local options.
+			Without argument: Display local values for all local
+			options which are different from the default.
+			When displaying a specific local option, show the
+			local value.  For a global/local boolean option, when
+			the global value is being used, "--" is displayed
+			before the option name.
+			For a global option the global value is
+			shown (but that might change in the future).
+
+:setl[ocal] {option}<	Set the local value of {option} to its global value by
+			copying the value.
+
+:se[t] {option}<	For |global-local| options: Remove the local value of
+			{option}, so that the global value will be used.
+
+							*:setg* *:setglobal*
+:setg[lobal][!] ...	Like ":set" but set only the global value for a local
+			option without changing the local value.
+			When displaying an option, the global value is shown.
+			With the "all" argument: display global values for all
+			local options.
+			Without argument: display global values for all local
+			options which are different from the default.
+
+For buffer-local and window-local options:
+	Command		 global value	    local value ~
+      :set option=value	     set		set
+ :setlocal option=value	      -			set
+:setglobal option=value	     set		 -
+      :set option?	      -		       display
+ :setlocal option?	      -		       display
+:setglobal option?	    display		 -
+
+
+Global options with a local value			*global-local*
+
+Options are global when you mostly use one value for all buffers and windows.
+For some global options it's useful to sometimes have a different local value.
+You can set the local value with ":setlocal".  That buffer or window will then
+use the local value, while other buffers and windows continue using the global
+value.
+
+For example, you have two windows, both on C source code.  They use the global
+'makeprg' option.  If you do this in one of the two windows: >
+	:set makeprg=gmake
+then the other window will switch to the same value.  There is no need to set
+the 'makeprg' option in the other C source window too.
+However, if you start editing a Perl file in a new window, you want to use
+another 'makeprg' for it, without changing the value used for the C source
+files.  You use this command: >
+	:setlocal makeprg=perlmake
+You can switch back to using the global value by making the local value empty: >
+	:setlocal makeprg=
+This only works for a string option.  For a number or boolean option you need
+to use the "<" flag, like this: >
+	:setlocal autoread<
+Note that for non-boolean and non-number options using "<" copies the global
+value to the local value, it doesn't switch back to using the global value
+(that matters when the global value changes later).  You can also use: >
+	:set path<
+This will make the local value of 'path' empty, so that the global value is
+used.  Thus it does the same as: >
+	:setlocal path=
+Note: In the future more global options can be made |global-local|.  Using
+":setlocal" on a global option might work differently then.
+
+
+						*option-value-function*
+Some options ('completefunc', 'imactivatefunc', 'imstatusfunc', 'omnifunc',
+'operatorfunc', 'quickfixtextfunc', 'tagfunc' and 'thesaurusfunc') are set to
+a function name or a function reference or a lambda function.  When using a
+lambda it will be converted to the name, e.g. "<lambda>123".  Examples:
+>
+	set opfunc=MyOpFunc
+	set opfunc=function('MyOpFunc')
+	set opfunc=funcref('MyOpFunc')
+	set opfunc={a\ ->\ MyOpFunc(a)}
+
+Set to a script-local function: >
+	set opfunc=s:MyLocalFunc
+	set opfunc=<SID>MyLocalFunc
+In |Vim9| script the "s:" and "<SID>" can be omitted if the function exists in
+the script: >
+	set opfunc=MyLocalFunc
+
+Set using a funcref variable: >
+	let Fn = function('MyTagFunc')
+	let &tagfunc = Fn
+
+Set using a lambda expression: >
+	let &tagfunc = {t -> MyTagFunc(t)}
+
+Set using a variable with lambda expression: >
+	let L = {a, b, c -> MyTagFunc(a, b , c)}
+	let &tagfunc = L
+
+In Vim9 script, in a compiled function, you can use a lambda, but a
+closured does not work, because the function will be called without the
+context of where it was defined.
+
+
+Setting the filetype
+
+:setf[iletype] [FALLBACK] {filetype}			*:setf* *:setfiletype*
+			Set the 'filetype' option to {filetype}, but only if
+			not done yet in a sequence of (nested) autocommands.
+			This is short for: >
+				:if !did_filetype()
+				:  setlocal filetype={filetype}
+				:endif
+<			This command is used in a filetype.vim file to avoid
+			setting the 'filetype' option twice, causing different
+			settings and syntax files to be loaded.
+
+			When the optional FALLBACK argument is present, a
+			later :setfiletype command will override the
+			'filetype'.  This is to be used for filetype
+			detections that are just a guess.  |did_filetype()|
+			will return false after this command.
+
+				*option-window* *optwin*
+:bro[wse] se[t]			*:set-browse* *:browse-set* *:opt* *:options*
+:opt[ions]		Open a window for viewing and setting all options.
+			Options are grouped by function.
+			Offers short help for each option.  Hit <CR> on the
+			short help to open a help window with more help for
+			the option.
+			Modify the value of the option and hit <CR> on the
+			"set" line to set the new value.  For window and
+			buffer specific options, the last accessed window is
+			used to set the option value in, unless this is a help
+			window, in which case the window below help window is
+			used (skipping the option-window).
+			{not available when compiled without the |+eval|
+			feature}
+
+								*$HOME*
+Using "~" is like using "$HOME", but it is only recognized at the start of an
+option and after a space or comma.
+
+On Unix systems "~user" can be used too.  It is replaced by the home directory
+of user "user".  Example: >
+    :set path=~mool/include,/usr/include,.
+
+On Unix systems the form "${HOME}" can be used too.  The name between {} can
+contain non-id characters then.  Note that if you want to use this for the
+"gf" command, you need to add the '{' and '}' characters to 'isfname'.
+
+NOTE: expanding environment variables and "~/" is only done with the ":set"
+command, not when assigning a value to an option with ":let".
+
+							*$HOME-windows*
+On MS-Windows, if $HOME is not defined as an environment variable, then
+at runtime Vim will set it to the expansion of $HOMEDRIVE$HOMEPATH.
+If $HOMEDRIVE is not set then $USERPROFILE is used.
+
+This expanded value is not exported to the environment, this matters when
+running an external command: >
+	:echo system('set | findstr ^HOME=')
+and >
+	:echo luaeval('os.getenv("HOME")')
+should echo nothing (an empty string) despite exists('$HOME') being true.
+When setting $HOME to a non-empty string it will be exported to the
+subprocesses.
+
+
+Note the maximum length of an expanded option is limited.  How much depends on
+the system, mostly it is something like 256 or 1024 characters.
+
+							*:fix* *:fixdel*
+:fix[del]		Set the value of 't_kD':
+				't_kb' is     't_kD' becomes	~
+				  CTRL-?	CTRL-H
+				not CTRL-?	CTRL-?
+
+			(CTRL-? is 0o177 octal, 0x7f hex)
+
+			If your delete key terminal code is wrong, but the
+			code for backspace is alright, you can put this in
+			your .vimrc: >
+				:fixdel
+<			This works no matter what the actual code for
+			backspace is.
+
+			If the backspace key terminal code is wrong you can
+			use this: >
+				:if &term == "termname"
+				:  set t_kb=^V<BS>
+				:  fixdel
+				:endif
+<			Where "^V" is CTRL-V and "<BS>" is the backspace key
+			(don't type four characters!).  Replace "termname"
+			with your terminal name.
+
+			If your <Delete> key sends a strange key sequence (not
+			CTRL-? or CTRL-H) you cannot use ":fixdel".  Then use: >
+				:if &term == "termname"
+				:  set t_kD=^V<Delete>
+				:endif
+<			Where "^V" is CTRL-V and "<Delete>" is the delete key
+			(don't type eight characters!).  Replace "termname"
+			with your terminal name.
+
+							*Linux-backspace*
+			Note about Linux: By default the backspace key
+			produces CTRL-?, which is wrong.  You can fix it by
+			putting this line in your rc.local: >
+				echo "keycode 14 = BackSpace" | loadkeys
+<
+							*NetBSD-backspace*
+			Note about NetBSD: If your backspace doesn't produce
+			the right code, try this: >
+				xmodmap -e "keycode 22 = BackSpace"
+<			If this works, add this in your .Xmodmap file: >
+				keysym 22 = BackSpace
+<			You need to restart for this to take effect.
+
+==============================================================================
+2. Automatically setting options			*auto-setting*
+
+Besides changing options with the ":set" command, there are three alternatives
+to set options automatically for one or more files:
+
+1. When starting Vim initializations are read from various places.  See
+   |initialization|.  Most of them are performed for all editing sessions,
+   and some of them depend on the directory where Vim is started.
+   You can create an initialization file with |:mkvimrc|, |:mkview| and
+   |:mksession|.
+2. If you start editing a new file, the automatic commands are executed.
+   This can be used to set options for files matching a particular pattern and
+   many other things.  See |autocommand|.
+3. If you start editing a new file, and the 'modeline' option is on, a
+   number of lines at the beginning and end of the file are checked for
+   modelines.  This is explained here.
+
+					*modeline* *vim:* *vi:* *ex:* *E520*
+There are two forms of modelines.  The first form:
+	[text{white}]{vi:|vim:|ex:}[white]{options}
+
+[text{white}]		empty or any text followed by at least one blank
+			character (<Space> or <Tab>); "ex:" always requires at
+			least one blank character
+{vi:|vim:|ex:}		the string "vi:", "vim:" or "ex:"
+[white]			optional white space
+{options}		a list of option settings, separated with white space
+			or ':', where each part between ':' is the argument
+			for a ":set" command (can be empty)
+
+Examples:
+   vi:noai:sw=3 ts=6 ~
+   vim: tw=77 ~
+
+The second form (this is compatible with some versions of Vi):
+
+	[text{white}]{vi:|vim:|Vim:|ex:}[white]se[t] {options}:[text]
+
+[text{white}]		empty or any text followed by at least one blank
+			character (<Space> or <Tab>); "ex:" always requires at
+			least one blank character
+{vi:|vim:|Vim:|ex:}	the string "vi:", "vim:", "Vim:" or "ex:"
+[white]			optional white space
+se[t]			the string "set " or "se " (note the space); When
+			"Vim" is used it must be "set".
+{options}		a list of options, separated with white space, which
+			is the argument for a ":set" command
+:			a colon
+[text]			any text or empty
+
+Examples:
+   /* vim: set ai tw=75: */ ~
+   /* Vim: set ai tw=75: */ ~
+
+The white space before {vi:|vim:|Vim:|ex:} is required.  This minimizes the
+chance that a normal word like "lex:" is caught.  There is one exception:
+"vi:" and "vim:" can also be at the start of the line (for compatibility with
+version 3.0).  Using "ex:" at the start of the line will be ignored (this
+could be short for "example:").
+
+If the modeline is disabled within a modeline, subsequent modelines will be
+ignored.  This is to allow turning off modeline on a per-file basis.  This is
+useful when a line looks like a modeline but isn't.  For example, it would be
+good to start a YAML file containing strings like "vim:" with
+    # vim: nomodeline ~
+so as to avoid modeline misdetection.  Following options on the same line
+after modeline deactivation, if any, are still evaluated (but you would
+normally not have any).
+
+							*modeline-local*
+The options are set like with ":setlocal": The new value only applies to the
+buffer and window that contain the file.  Although it's possible to set global
+options from a modeline, this is unusual.  If you have two windows open and
+the files in it set the same global option to a different value, the result
+depends on which one was opened last.
+
+When editing a file that was already loaded, only the window-local options
+from the modeline are used.  Thus if you manually changed a buffer-local
+option after opening the file, it won't be changed if you edit the same buffer
+in another window.  But window-local options will be set.
+
+							*modeline-version*
+If the modeline is only to be used for some versions of Vim, the version
+number can be specified where "vim:" or "Vim:" is used:
+	vim{vers}:	version {vers} or later
+	vim<{vers}:	version before {vers}
+	vim={vers}:	version {vers}
+	vim>{vers}:	version after {vers}
+{vers} is 700 for Vim 7.0 (hundred times the major version plus minor).
+For example, to use a modeline only for Vim 7.0:
+	/* vim700: set foldmethod=marker */ ~
+To use a modeline for Vim after version 7.2:
+	/* vim>702: set cole=2: */ ~
+There can be no blanks between "vim" and the ":".
+
+
+The number of lines that are checked can be set with the 'modelines' option.
+If 'modeline' is off or 'modelines' is 0 no lines are checked.
+
+Note that for the first form all of the rest of the line is used, thus a line
+like:
+   /* vi:ts=4: */ ~
+will give an error message for the trailing "*/".  This line is OK:
+   /* vi:set ts=4: */ ~
+
+If an error is detected the rest of the line is skipped.
+
+If you want to include a ':' in a set command precede it with a '\'.  The
+backslash in front of the ':' will be removed.  Example:
+   /* vi:set fillchars=stl\:^,vert\:\|: */ ~
+This sets the 'fillchars' option to "stl:^,vert:\|".  Only a single backslash
+before the ':' is removed.  Thus to include "\:" you have to specify "\\:".
+							*E992*
+No other commands than "set" are supported, for security reasons (somebody
+might create a Trojan horse text file with modelines).  And not all options
+can be set.  For some options a flag is set, so that when the value is used
+the |sandbox| is effective.  Some options can only be set from the modeline
+when 'modelineexpr' is set (the default is off).
+
+Still, there is always a small risk that a modeline causes trouble.  E.g.,
+when some joker sets 'textwidth' to 5 all your lines are wrapped unexpectedly.
+So disable modelines before editing untrusted text.  The mail ftplugin does
+this, for example.
+
+Hint: If you would like to do something else than setting an option, you could
+define an autocommand that checks the file for a specific string.  For
+example: >
+	au BufReadPost * if getline(1) =~ "VAR" | call SetVar() | endif
+And define a function SetVar() that does something with the line containing
+"VAR".
+
+==============================================================================
+3. Options summary					*option-summary*
+
+In the list below all the options are mentioned with their full name and with
+an abbreviation if there is one.  Both forms may be used.
+
+In this document when a boolean option is "set" that means that ":set option"
+is entered.  When an option is "reset", ":set nooption" is used.
+
+For some options there are two default values: The "Vim default", which is
+used when 'compatible' is not set, and the "Vi default", which is used when
+'compatible' is set.
+
+Most options are the same in all windows and buffers.  There are a few that
+are specific to how the text is presented in a window.  These can be set to a
+different value in each window.  For example the 'list' option can be set in
+one window and reset in another for the same text, giving both types of view
+at the same time.  There are a few options that are specific to a certain
+file.  These can have a different value for each file or buffer.  For example
+the 'textwidth' option can be 78 for a normal text file and 0 for a C
+program.
+
+	global			one option for all buffers and windows
+	local to window		each window has its own copy of this option
+	local to buffer		each buffer has its own copy of this option
+
+When creating a new window the option values from the currently active window
+are used as a default value for the window-specific options.  For the
+buffer-specific options this depends on the 's' and 'S' flags in the
+'cpoptions' option.  If 's' is included (which is the default) the values for
+buffer options are copied from the currently active buffer when a buffer is
+first entered.  If 'S' is present the options are copied each time the buffer
+is entered, this is almost like having global options.  If 's' and 'S' are not
+present, the options are copied from the currently active buffer when the
+buffer is created.
+
+Hidden options						*hidden-options*
+
+Not all options are supported in all versions.  This depends on the supported
+features and sometimes on the system.  A remark about this is in curly braces
+below.  When an option is not supported it may still be set without getting an
+error, this is called a hidden option.  You can't get the value of a hidden
+option though, it is not stored.
+
+To test if option "foo" can be used with ":set" use something like this: >
+	if exists('&foo')
+This also returns true for a hidden option.  To test if option "foo" is really
+supported use something like this: >
+	if exists('+foo')
+<
+							*E355*
+A jump table for the options with a short description can be found at |Q_op|.
+
+					*'aleph'* *'al'* *aleph* *Aleph*
+'aleph' 'al'		number	(default 128 for MS-Windows, 224 otherwise)
+			global
+			{only available when compiled with the |+rightleft|
+			feature}
+	The ASCII code for the first letter of the Hebrew alphabet.  The
+	routine that maps the keyboard in Hebrew mode, both in Insert mode
+	(when hkmap is set) and on the command-line (when hitting CTRL-_)
+	outputs the Hebrew characters in the range [aleph..aleph+26].
+	aleph=128 applies to PC code, and aleph=224 applies to ISO 8859-8.
+	See |rileft.txt|.
+
+			*'allowrevins'* *'ari'* *'noallowrevins'* *'noari'*
+'allowrevins' 'ari'	boolean	(default off)
+			global
+			{only available when compiled with the |+rightleft|
+			feature}
+	Allow CTRL-_ in Insert and Command-line mode.  This is default off, to
+	avoid that users that accidentally type CTRL-_ instead of SHIFT-_ get
+	into reverse Insert mode, and don't know how to get out.  See
+	'revins'.
+	NOTE: This option is reset when 'compatible' is set.
+
+			 *'altkeymap'* *'akm'* *'noaltkeymap'* *'noakm'*
+'altkeymap' 'akm'	boolean (default off)
+			global
+			{only available when compiled with the |+farsi|
+			feature}
+	This option was for using Farsi, which has been removed.  See
+	|farsi.txt|.
+
+						*'ambiwidth'* *'ambw'*
+'ambiwidth' 'ambw'	string (default: "single")
+			global
+	Only effective when 'encoding' is "utf-8" or another Unicode encoding.
+	Tells Vim what to do with characters with East Asian Width Class
+	Ambiguous (such as Euro, Registered Sign, Copyright Sign, Greek
+	letters, Cyrillic letters).
+
+	There are currently two possible values:
+	"single":	Use the same width as characters in US-ASCII.  This is
+			expected by most users.
+	"double":	Use twice the width of ASCII characters.
+							*E834* *E835*
+	The value "double" cannot be used if 'listchars' or 'fillchars'
+	contains a character that would be double width.  These errors may
+	also be given when calling setcellwidths().
+
+	The values are overruled for characters specified with
+	|setcellwidths()|.
+
+	There are a number of CJK fonts for which the width of glyphs for
+	those characters are solely based on how many octets they take in
+	legacy/traditional CJK encodings.  In those encodings, Euro,
+	Registered sign, Greek/Cyrillic letters are represented by two octets,
+	therefore those fonts have "wide" glyphs for them.  This is also
+	true of some line drawing characters used to make tables in text
+	file.  Therefore, when a CJK font is used for GUI Vim or
+	Vim is running inside a terminal (emulators) that uses a CJK font
+	(or Vim is run inside an xterm invoked with "-cjkwidth" option.),
+	this option should be set to "double" to match the width perceived
+	by Vim with the width of glyphs in the font.  Perhaps it also has
+	to be set to "double" under CJK MS-Windows when the system locale is
+	set to one of CJK locales.  See Unicode Standard Annex #11
+	(http://www.unicode.org/reports/tr11).
+
+	Vim may set this option automatically at startup time when Vim is
+	compiled with the |+termresponse| feature and if |t_u7| is set to the
+	escape sequence to request cursor position report.  The response can
+	be found in |v:termu7resp|.
+
+			*'antialias'* *'anti'* *'noantialias'* *'noanti'*
+'antialias' 'anti'	boolean (default: off)
+			global
+			{only available when compiled with GUI enabled
+			on macOS}
+	This option only has an effect in the GUI version of Vim on macOS
+	v10.2 or later.  When on, Vim will use smooth ("antialiased") fonts,
+	which can be easier to read at certain sizes on certain displays.
+	Setting this option can sometimes cause problems if 'guifont' is set
+	to its default (empty string).
+	NOTE: This option is reset when 'compatible' is set.
+
+			*'autochdir'* *'acd'* *'noautochdir'* *'noacd'*
+'autochdir' 'acd'	boolean (default off)
+			global
+			{only available when compiled with it, use
+			exists("+autochdir") to check}
+	When on, Vim will change the current working directory whenever you
+	open a file, switch buffers, delete a buffer or open/close a window.
+	It will change to the directory containing the file which was opened
+	or selected.  When a buffer has no name it also has no directory, thus
+	the current directory won't change when navigating to it.
+	Note: When this option is on some plugins may not work.
+
+			*'autoshelldir'* *'asd'* *'noautoshelldir'* *'noasd'*
+'autoshelldir' 'asd'	boolean (default off)

+	When on, Vim will change the current working directory whenever you
+	change the directory of the shell running in a terminal window. You
+	need proper setting-up, so whenever the shell's pwd changes an OSC 7
+	escape sequence will be emitted.  For example, on Linux, you can
+	source /etc/profile.d/vte.sh in your shell profile if you use bash or
+	zsh.  For bash this should work (put it in a bash init file): >
+		if [[ -n "$VIM_TERMINAL" ]]; then

+		    function _vim_sync_PWD() {
+			printf '\033]7;file://%s\033\\' "$PWD"

+				*'arabic'* *'arab'* *'noarabic'* *'noarab'*
+'arabic' 'arab'		boolean (default off)
+			local to window
+			{only available when compiled with the |+arabic|
+			feature}
+	This option can be set to start editing Arabic text.
+	Setting this option will:
+	- Set the 'rightleft' option, unless 'termbidi' is set.
+	- Set the 'arabicshape' option, unless 'termbidi' is set.
+	- Set the 'keymap' option to "arabic"; in Insert mode CTRL-^ toggles
+	  between typing English and Arabic key mapping.
+	- Set the 'delcombine' option
+	Note that 'encoding' must be "utf-8" for working with Arabic text.
+
+	Resetting this option will:
+	- Reset the 'rightleft' option.
+	- Disable the use of 'keymap' (without changing its value).
+	Note that 'arabicshape' and 'delcombine' are not reset (it is a global
+	option).
+	NOTE: This option is reset when 'compatible' is set.
+	Also see |arabic.txt|.

+					*'noarabicshape'* *'noarshape'*
+'arabicshape' 'arshape'	boolean (default on)
+			global
+			{only available when compiled with the |+arabic|
+			feature}
+	When on and 'termbidi' is off, the required visual character
+	corrections that need to take place for displaying the Arabic language
+	take effect.  Shaping, in essence, gets enabled; the term is a broad
+	one which encompasses:
+	  a) the changing/morphing of characters based on their location
+	     within a word (initial, medial, final and stand-alone).
+	  b) the enabling of the ability to compose characters
+	  c) the enabling of the required combining of some characters
+	When disabled the display shows each character's true stand-alone
+	form.
+	Arabic is a complex language which requires other settings, for
+	further details see |arabic.txt|.
+	NOTE: This option is set when 'compatible' is set.
+
+			*'autoindent'* *'ai'* *'noautoindent'* *'noai'*
+'autoindent' 'ai'	boolean	(default off)
+			local to buffer
+	Copy indent from current line when starting a new line (typing <CR>
+	in Insert mode or when using the "o" or "O" command).  If you do not
+	type anything on the new line except <BS> or CTRL-D and then type
+	<Esc>, CTRL-O or <CR>, the indent is deleted again.  Moving the cursor
+	to another line has the same effect, unless the 'I' flag is included
+	in 'cpoptions'.
+	When autoindent is on, formatting (with the "gq" command or when you
+	reach 'textwidth' in Insert mode) uses the indentation of the first
+	line.
+	When 'smartindent' or 'cindent' is on the indent is changed in
+	a different way.
+	The 'autoindent' option is reset when the 'paste' option is set and
+	restored when 'paste' is reset.
+
+				 *'autoread'* *'ar'* *'noautoread'* *'noar'*

+			global or local to buffer |global-local|
+	When a file has been detected to have been changed outside of Vim and
+	it has not been changed inside of Vim, automatically read it again.
+	When the file has been deleted this is not done, so you have the text
+	from before it was deleted.  When it appears again then it is read.
+	|timestamp|
+	If this option has a local value, use this command to switch back to

+				 *'autowrite'* *'aw'* *'noautowrite'* *'noaw'*
+'autowrite' 'aw'	boolean	(default off)
+			global
+	Write the contents of the file, if it has been modified, on each
+	`:next`, `:rewind`, `:last`, `:first`, `:previous`, `:stop`,
+	`:suspend`, `:tag`, `:!`, `:make`, CTRL-] and CTRL-^ command; and when
+	a `:buffer`, CTRL-O, CTRL-I, '{A-Z0-9}, or `{A-Z0-9} command takes one
+	to another file.
+	A buffer is not written if it becomes hidden, e.g. when 'bufhidden' is
+	set to "hide" and `:next` is used.
+	Note that for some commands the 'autowrite' option is not used, see
+	'autowriteall' for that.
+	Some buffers will not be written, specifically when 'buftype' is
+	"nowrite", "nofile", "terminal" or "prompt".
+	USE WITH CARE: If you make temporary changes to a buffer that you
+	don't want to be saved this option may cause it to be saved anyway.
+	Renaming the buffer with ":file {name}" may help avoid this.
+
+			 *'autowriteall'* *'awa'* *'noautowriteall'* *'noawa'*
+'autowriteall' 'awa'	boolean	(default off)
+			global
+	Like 'autowrite', but also used for commands ":edit", ":enew", ":quit",
+	":qall", ":exit", ":xit", ":recover" and closing the Vim window.
+	Setting this option also implies that Vim behaves like 'autowrite' has
+	been set.
+
+							*'background'* *'bg'*
+'background' 'bg'	string	(default "dark" or "light", see below)
+			global
+	When set to "dark", Vim will try to use colors that look good on a
+	dark background.  When set to "light", Vim will try to use colors that
+	look good on a light background.  Any other value is illegal.
+	Vim tries to set the default value according to the terminal used.
+	This will not always be correct.
+	Setting this option does not change the background color, it tells Vim
+	what the background color looks like.  For changing the background
+	color, see |:hi-normal|.
+
+	When 'background' is set Vim will adjust the default color groups for
+	the new value.  But the colors used for syntax highlighting will not
+	change.					*g:colors_name*
+	When a color scheme is loaded (the "g:colors_name" variable is set)
+	setting 'background' will cause the color scheme to be reloaded.  If
+	the color scheme adjusts to the value of 'background' this will work.
+	However, if the color scheme sets 'background' itself the effect may
+	be undone.  First delete the "g:colors_name" variable when needed.
+
+	When setting 'background' to the default value with: >
+		:set background&
+<	Vim will guess the value.  In the GUI this should work correctly,
+	in other cases Vim might not be able to guess the right value.
+	If the GUI supports a dark theme, you can use the "d" flag in
+	'guioptions', see 'go-d'.
+
+	When the |t_RB| option is set, Vim will use it to request the background
+	color from the terminal.  If the returned RGB value is dark/light and
+	'background' is not dark/light, 'background' will be set and the
+	screen is redrawn.  This may have side effects, make t_BG empty in
+	your .vimrc if you suspect this problem.  The response to |t_RB| can
+	be found in |v:termrbgresp|.
+
+	When starting the GUI, the default value for 'background' will be
+	"light".  When the value is not set in the .gvimrc, and Vim detects
+	that the background is actually quite dark, 'background' is set to
+	"dark".  But this happens only AFTER the .gvimrc file has been read
+	(because the window needs to be opened to find the actual background
+	color).  To get around this, force the GUI window to be opened by
+	putting a ":gui" command in the .gvimrc file, before where the value
+	of 'background' is used (e.g., before ":syntax on").
+
+	For MS-Windows the default is "dark".
+	For other systems "dark" is used when 'term' is "linux",
+	"screen.linux", "cygwin" or "putty", or $COLORFGBG suggests a dark
+	background.  Otherwise the default is "light".
+
+	The |:terminal| command and the |term_start()| function use the
+	'background' value to decide whether the terminal window will start
+	with a white or black background.
+
+	Normally this option would be set in the .vimrc file.  Possibly
+	depending on the terminal name.  Example: >
+		:if &term == "pcterm"
+		:  set background=dark
+		:endif
+<	When this option is set, the default settings for the highlight groups
+	will change.  To use other settings, place ":highlight" commands AFTER
+	the setting of the 'background' option.
+	This option is also used in the "$VIMRUNTIME/syntax/syntax.vim" file
+	to select the colors for syntax highlighting.  After changing this
+	option, you must load syntax.vim again to see the result.  This can be
+	done with ":syntax on".
+
+							*'backspace'* *'bs'*
+'backspace' 'bs'	string	(default "", set to "indent,eol,start"
+							    in |defaults.vim|)
+			global
+	Influences the working of <BS>, <Del>, CTRL-W and CTRL-U in Insert
+	mode.  This is a list of items, separated by commas.  Each item allows
+	a way to backspace over something:
+	value	effect	~
+	indent	allow backspacing over autoindent
+	eol	allow backspacing over line breaks (join lines)
+	start	allow backspacing over the start of insert; CTRL-W and CTRL-U
+		stop once at the start of insert.
+	nostop	like start, except CTRL-W and CTRL-U do not stop at the start of
+		insert.
+
+	When the value is empty, Vi compatible backspacing is used, none of
+	the ways mentioned for the items above are possible.
+
+	For backwards compatibility with version 5.4 and earlier:
+	value	effect	~
+	  0	same as ":set backspace=" (Vi compatible)
+	  1	same as ":set backspace=indent,eol"
+	  2	same as ":set backspace=indent,eol,start"
+	  3	same as ":set backspace=indent,eol,nostop"
+
+	See |:fixdel| if your <BS> or <Del> key does not do what you want.
+	NOTE: This option is set to "" when 'compatible' is set.
+
+				*'backup'* *'bk'* *'nobackup'* *'nobk'*
+'backup' 'bk'		boolean	(default off)
+			global
+	Make a backup before overwriting a file.  Leave it around after the
+	file has been successfully written.  If you do not want to keep the
+	backup file, but you do want a backup while the file is being
+	written, reset this option and set the 'writebackup' option (this is
+	the default).  If you do not want a backup file at all reset both
+	options (use this if your file system is almost full).  See the
+	|backup-table| for more explanations.
+	When the 'backupskip' pattern matches, a backup is not made anyway.
+	When 'patchmode' is set, the backup may be renamed to become the
+	oldest version of a file.
+	NOTE: This option is reset when 'compatible' is set.
+
+						*'backupcopy'* *'bkc'*
+'backupcopy' 'bkc'	string	(Vi default for Unix: "yes", otherwise: "auto")
+			global or local to buffer |global-local|
+	When writing a file and a backup is made, this option tells how it's
+	done.  This is a comma-separated list of words.
+
+	The main values are:
+	"yes"	make a copy of the file and overwrite the original one
+	"no"	rename the file and write a new one
+	"auto"	one of the previous, what works best
+
+	Extra values that can be combined with the ones above are:
+	"breaksymlink"	always break symlinks when writing
+	"breakhardlink"	always break hardlinks when writing
+
+	Making a copy and overwriting the original file:
+	- Takes extra time to copy the file.
+	+ When the file has special attributes, is a (hard/symbolic) link or
+	  has a resource fork, all this is preserved.
+	- When the file is a link the backup will have the name of the link,
+	  not of the real file.
+
+	Renaming the file and writing a new one:
+	+ It's fast.
+	- Sometimes not all attributes of the file can be copied to the new
+	  file.
+	- When the file is a link the new file will not be a link.
+
+	The "auto" value is the middle way: When Vim sees that renaming the
+	file is possible without side effects (the attributes can be passed on
+	and the file is not a link) that is used.  When problems are expected,
+	a copy will be made.
+
+	The "breaksymlink" and "breakhardlink" values can be used in
+	combination with any of "yes", "no" and "auto".  When included, they
+	force Vim to always break either symbolic or hard links by doing
+	exactly what the "no" option does, renaming the original file to
+	become the backup and writing a new file in its place.  This can be
+	useful for example in source trees where all the files are symbolic or
+	hard links and any changes should stay in the local source tree, not
+	be propagated back to the original source.
+							*crontab*
+	One situation where "no" and "auto" will cause problems: A program
+	that opens a file, invokes Vim to edit that file, and then tests if
+	the open file was changed (through the file descriptor) will check the
+	backup file instead of the newly created file.  "crontab -e" is an
+	example.
+
+	When a copy is made, the original file is truncated and then filled
+	with the new text.  This means that protection bits, owner and
+	symbolic links of the original file are unmodified.  The backup file,
+	however, is a new file, owned by the user who edited the file.  The
+	group of the backup is set to the group of the original file.  If this
+	fails, the protection bits for the group are made the same as for
+	others.
+
+	When the file is renamed, this is the other way around: The backup has
+	the same attributes of the original file, and the newly written file
+	is owned by the current user.  When the file was a (hard/symbolic)
+	link, the new file will not!  That's why the "auto" value doesn't
+	rename when the file is a link.  The owner and group of the newly
+	written file will be set to the same ones as the original file, but
+	the system may refuse to do this.  In that case the "auto" value will
+	again not rename the file.
+
+	NOTE: This option is set to the Vi default value when 'compatible' is
+	set and to the Vim default value when 'compatible' is reset.
+
+						*'backupdir'* *'bdir'*
+'backupdir' 'bdir'	string	(default for Amiga: ".,t:",
+				 for Win32: ".,$TEMP,c:/tmp,c:/temp"
+				 for Unix: ".,~/tmp,~/")
+			global
+	List of directories for the backup file, separated with commas.
+	- The backup file will be created in the first directory in the list
+	  where this is possible.  The directory must exist, Vim will not
+	  create it for you.
+	- Empty means that no backup file will be created ('patchmode' is
+	  impossible!).  Writing may fail because of this.
+	- A directory "." means to put the backup file in the same directory
+	  as the edited file.
+	- A directory starting with "./" (or ".\" for MS-Windows) means to put
+	  the backup file relative to where the edited file is.  The leading
+	  "." is replaced with the path name of the edited file.
+	  ("." inside a directory name has no special meaning).
+	- Spaces after the comma are ignored, other spaces are considered part
+	  of the directory name.  To have a space at the start of a directory
+	  name, precede it with a backslash.
+	- To include a comma in a directory name precede it with a backslash.
+	- A directory name may end in an '/'.
+	- For Unix and Win32, if a directory ends in two path separators "//",
+	  the backup file name will be built from the complete path to the
+	  file with all path separators changed to percent '%' signs. This
+	  will ensure file name uniqueness in the backup directory.
+	  On Win32, it is also possible to end with "\\".  However, When a
+	  separating comma is following, you must use "//", since "\\" will
+	  include the comma in the file name. Therefore it is recommended to
+	  use '//', instead of '\\'.
+	- Environment variables are expanded |:set_env|.
+	- Careful with '\' characters, type one before a space, type two to
+	  get one in the option (see |option-backslash|), for example: >
+	    :set bdir=c:\\tmp,\ dir\\,with\\,commas,\\\ dir\ with\ spaces
+<	- For backwards compatibility with Vim version 3.0 a '>' at the start
+	  of the option is removed.
+	See also 'backup' and 'writebackup' options.
+	If you want to hide your backup files on Unix, consider this value: >
+		:set backupdir=./.backup,~/.backup,.,/tmp
+<	You must create a ".backup" directory in each directory and in your
+	home directory for this to work properly.
+	The use of |:set+=| and |:set-=| is preferred when adding or removing
+	directories from the list.  This avoids problems when a future version
+	uses another default.
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+						*'backupext'* *'bex'* *E589*
+'backupext' 'bex'	string	(default "~", for VMS: "_")
+			global
+	String which is appended to a file name to make the name of the
+	backup file.  The default is quite unusual, because this avoids
+	accidentally overwriting existing files with a backup file.  You might
+	prefer using ".bak", but make sure that you don't have files with
+	".bak" that you want to keep.
+	Only normal file name characters can be used; "/\*?[|<>" are illegal.
+
+	If you like to keep a lot of backups, you could use a BufWritePre
+	autocommand to change 'backupext' just before writing the file to
+	include a timestamp. >
+		:au BufWritePre * let &bex = '-' .. strftime("%Y%b%d%X") .. '~'
+<	Use 'backupdir' to put the backup in a different directory.
+
+						*'backupskip'* *'bsk'*
+'backupskip' 'bsk'	string	(default: "$TMPDIR/*,$TMP/*,$TEMP/*"
+				 Unix: "/tmp/*,$TMPDIR/*,$TMP/*,$TEMP/*"
+				 Mac: "/private/tmp/*,$TMPDIR/*,$TMP/*,$TEMP/*")
+			global
+	A list of file patterns.  When one of the patterns matches with the
+	name of the file which is written, no backup file is created.  Both
+	the specified file name and the full path name of the file are used.
+	The pattern is used like with |:autocmd|, see |autocmd-patterns|.
+	Watch out for special characters, see |option-backslash|.
+	When $TMPDIR, $TMP or $TEMP is not defined, it is not used for the
+	default value.  "/tmp/*" is only used for Unix.
+
+	WARNING: Not having a backup file means that when Vim fails to write
+	your buffer correctly and then, for whatever reason, Vim exits, you
+	lose both the original file and what you were writing.  Only disable
+	backups if you don't care about losing the file.
+
+	Note that environment variables are not expanded.  If you want to use
+	$HOME you must expand it explicitly, e.g.: >
+		:let &backupskip = escape(expand('$HOME'), '\') .. '/tmp/*'
+
+<	Note that the default also makes sure that "crontab -e" works (when a
+	backup would be made by renaming the original file crontab won't see
+	the newly created file).  Also see 'backupcopy' and |crontab|.
+
+						*'balloondelay'* *'bdlay'*
+'balloondelay' 'bdlay'	number	(default: 600)

+'balloonexpr' 'bexpr'	string	(default "")
+			global or local to buffer |global-local|
+			{only available when compiled with the |+balloon_eval|
+			feature}
+	Expression for text to show in evaluation balloon.  It is only used
+	when 'ballooneval' or 'balloonevalterm' is on.  These variables can be
+	used:
+
+	v:beval_bufnr	number of the buffer in which balloon is going to show
+	v:beval_winnr	number of the window
+	v:beval_winid	ID of the window
+	v:beval_lnum	line number
+	v:beval_col	column number (byte index)
+	v:beval_text	word under or after the mouse pointer
+
+	Instead of showing a balloon, which is limited to plain text, consider
+	using a popup window, see |popup_beval_example|.  A popup window can
+	use highlighting and show a border.
+
+	The evaluation of the expression must not have side effects!
+	Example: >
+    function MyBalloonExpr()
+	return 'Cursor is at line ' .. v:beval_lnum ..
+		\ ', column ' .. v:beval_col ..
+		\ ' of file ' ..  bufname(v:beval_bufnr) ..
+		\ ' on word "' .. v:beval_text .. '"'
+    endfunction
+    set bexpr=MyBalloonExpr()
+    set ballooneval balloonevalterm
+<
+	Also see |balloon_show()|, it can be used if the content of the balloon
+	is to be fetched asynchronously.  In that case evaluating
+	'balloonexpr' should result in an empty string.  If you get a balloon
+	with only "0" you probably didn't return anything from your function.
+
+	NOTE: The balloon is displayed only if the cursor is on a text
+	character.  If the result of evaluating 'balloonexpr' is not empty,
+	Vim does not try to send a message to an external debugger (Netbeans
+	or Sun Workshop).
+
+	If the expression starts with s: or |<SID>|, then it is replaced with
+	the script ID (|local-function|). Example: >
+		set bexpr=s:MyBalloonExpr()
+		set bexpr=<SID>SomeBalloonExpr()
+<	Otherwise, the expression is evaluated in the context of the script
+	where the option was set, thus script-local items are available.
+
+	The expression will be evaluated in the |sandbox| when set from a
+	modeline, see |sandbox-option|.
+	This option cannot be set in a modeline when 'modelineexpr' is off.
+
+	It is not allowed to change text or jump to another window while
+	evaluating 'balloonexpr', see |textlock|.
+
+	To check whether line breaks in the balloon text work use this check: >
+		if has("balloon_multiline")
+<	When they are supported "\n" characters will start a new line.  If the
+	expression evaluates to a |List| this is equal to using each List item
+	as a string and putting "\n" in between them.
+	NOTE: This option is set to "" when 'compatible' is set.
+
+						*'belloff'* *'bo'*
+'belloff' 'bo'		string	(default "")
+			global
+	Specifies for which events the bell will not be rung. It is a comma

+		'modeline'   will be off
+		'expandtab'  will be off
+	Also, 'fileformat' and 'fileformats' options will not be used, the
+	file is read and written like 'fileformat' was "unix" (a single <NL>
+	separates lines).
+	The 'fileencoding' and 'fileencodings' options will not be used, the
+	file is read without conversion.
+	NOTE: When you start editing a(nother) file while the 'bin' option is
+	on, settings from autocommands may change the settings again (e.g.,
+	'textwidth'), causing trouble when editing.  You might want to set
+	'bin' again when the file has been loaded.
+	The previous values of these options are remembered and restored when
+	'bin' is switched from on to off.  Each buffer has its own set of
+	saved option values.
+	To edit a file with 'binary' set you can use the |++bin| argument.
+	This avoids you have to do ":set bin", which would have effect for all
+	files you edit.
+	When writing a file the <EOL> for the last line is only written if
+	there was one in the original file (normally Vim appends an <EOL> to
+	the last line if there is none; this would make the file longer).  See
+	the 'endofline' option.
+
+			*'bioskey'* *'biosk'* *'nobioskey'* *'nobiosk'*
+'bioskey' 'biosk'	boolean	(default on)
+			global
+			{only for MS-DOS}
+	This was for MS-DOS and is no longer supported.
+
+							*'bomb'* *'nobomb'*
+'bomb'			boolean	(default off)
+			local to buffer
+	When writing a file and the following conditions are met, a BOM (Byte
+	Order Mark) is prepended to the file:
+	- this option is on
+	- the 'binary' option is off
+	- 'fileencoding' is "utf-8", "ucs-2", "ucs-4" or one of the little/big
+	  endian variants.
+	Some applications use the BOM to recognize the encoding of the file.
+	Often used for UCS-2 files on MS-Windows.  For other applications it
+	causes trouble, for example: "cat file1 file2" makes the BOM of file2
+	appear halfway the resulting file.  Gcc doesn't accept a BOM.
+	When Vim reads a file and 'fileencodings' starts with "ucs-bom", a
+	check for the presence of the BOM is done and 'bomb' set accordingly.
+	Unless 'binary' is set, it is removed from the first line, so that you
+	don't see it when editing.  When you don't change the options, the BOM
+	will be restored when writing the file.
+
+						*'breakat'* *'brk'*
+'breakat' 'brk'		string	(default " ^I!@*-+;:,./?")
+			global
+			{not available when compiled without the |+linebreak|
+			feature}
+	This option lets you choose which characters might cause a line
+	break if 'linebreak' is on.  Only works for ASCII and also for 8-bit
+	characters when 'encoding' is an 8-bit encoding.
+
+			*'breakindent'* *'bri'* *'nobreakindent'* *'nobri'*
+'breakindent' 'bri'	boolean (default off)
+			local to window
+			{not available when compiled without the |+linebreak|
+			feature}
+	Every wrapped line will continue visually indented (same amount of
+	space as the beginning of that line), thus preserving horizontal blocks
+	of text.
+	NOTE: This option is reset when 'compatible' is set.
+
+						*'breakindentopt'* *'briopt'*
+'breakindentopt' 'briopt' string (default empty)
+			local to window
+			{not available when compiled without the |+linebreak|
+			feature}
+	Settings for 'breakindent'. It can consist of the following optional
+	items and must be separated by a comma:
+		min:{n}	    Minimum text width that will be kept after
+			    applying 'breakindent', even if the resulting
+			    text should normally be narrower. This prevents
+			    text indented almost to the right window border
+			    occupying lot of vertical space when broken.
+			    (default: 20)
+		shift:{n}   After applying 'breakindent', the wrapped line's
+			    beginning will be shifted by the given number of
+			    characters.  It permits dynamic French paragraph
+			    indentation (negative) or emphasizing the line
+			    continuation (positive).
+			    (default: 0)
+		sbr	    Display the 'showbreak' value before applying the
+			    additional indent.
+			    (default: off)
+		list:{n}    Adds an additional indent for lines that match a
+			    numbered or bulleted list (using the
+			    'formatlistpat' setting).
+		list:-1	    Uses the length of a match with 'formatlistpat'
+			    for indentation.
+			    (default: 0)
+		column:{n}  Indent at column {n}. Will overrule the other
+			    sub-options. Note: an additional indent may be
+			    added for the 'showbreak' setting.
+			    (default: off)
+
+						*'browsedir'* *'bsdir'*
+'browsedir' 'bsdir'	string	(default: "last")
+			global
+			{only for Motif, GTK, Mac and Win32 GUI}
+	Which directory to use for the file browser:
+	   last		Use same directory as with last file browser, where a
+			file was opened or saved.
+	   buffer	Use the directory of the related buffer.
+	   current	Use the current directory.
+	   {path}	Use the specified directory
+
+						*'bufhidden'* *'bh'*
+'bufhidden' 'bh'	string (default: "")
+			local to buffer
+	This option specifies what happens when a buffer is no longer
+	displayed in a window:
+	  <empty>	follow the global 'hidden' option
+	  hide		hide the buffer (don't unload it), even if 'hidden' is
+			not set
+	  unload	unload the buffer, even if 'hidden' is set; the
+			|:hide| command will also unload the buffer
+	  delete	delete the buffer from the buffer list, even if
+			'hidden' is set; the |:hide| command will also delete
+			the buffer, making it behave like |:bdelete|
+	  wipe		wipe the buffer from the buffer list, even if
+			'hidden' is set; the |:hide| command will also wipe
+			out the buffer, making it behave like |:bwipeout|
+
+	CAREFUL: when "unload", "delete" or "wipe" is used changes in a buffer
+	are lost without a warning.  Also, these values may break autocommands
+	that switch between buffers temporarily.
+	This option is used together with 'buftype' and 'swapfile' to specify
+	special kinds of buffers.   See |special-buffers|.
+
+			*'buflisted'* *'bl'* *'nobuflisted'* *'nobl'* *E85*
+'buflisted' 'bl'	boolean (default: on)
+			local to buffer
+	When this option is set, the buffer shows up in the buffer list.  If
+	it is reset it is not used for ":bnext", "ls", the Buffers menu, etc.
+	This option is reset by Vim for buffers that are only used to remember
+	a file name or marks.  Vim sets it when starting to edit a buffer.
+	But not when moving to a buffer with ":buffer".
+
+						*'buftype'* *'bt'* *E382*
+'buftype' 'bt'		string (default: "")
+			local to buffer
+	The value of this option specifies the type of a buffer:
+	  <empty>	normal buffer
+	  nofile	buffer which is not related to a file and will not be
+			written
+	  nowrite	buffer which will not be written
+	  acwrite	buffer which will always be written with BufWriteCmd
+			autocommands.
+	  quickfix	quickfix buffer, contains list of errors |:cwindow|
+			or list of locations |:lwindow|
+	  help		help buffer (you are not supposed to set this
+			manually)
+	  terminal	buffer for a |terminal| (you are not supposed to set
+			this manually)
+	  prompt	buffer where only the last line can be edited, meant
+			to be used by a plugin, see |prompt-buffer|
+			{only when compiled with the |+channel| feature}
+	  popup		buffer used in a popup window, see |popup|.
+			{only when compiled with the |+textprop| feature}
+
+	This option is used together with 'bufhidden' and 'swapfile' to
+	specify special kinds of buffers.   See |special-buffers|.
+	Also see |win_gettype()|, which returns the type of the window.
+
+	Be careful with changing this option, it can have many side effects!
+	One such effect is that Vim will not check the timestamp of the file,
+	if the file is changed by another program this will not be noticed.
+
+	A "quickfix" buffer is only used for the error list and the location
+	list.  This value is set by the |:cwindow| and |:lwindow| commands and
+	you are not supposed to change it.
+
+	"nofile" and "nowrite" buffers are similar:
+	both:		The buffer is not to be written to disk, ":w" doesn't
+			work (":w filename" does work though).
+	both:		The buffer is never considered to be |'modified'|.
+			There is no warning when the changes will be lost, for
+			example when you quit Vim.
+	both:		A swap file is only created when using too much memory
+			(when 'swapfile' has been reset there is never a swap
+			file).
+	nofile only:	The buffer name is fixed, it is not handled like a
+			file name.  It is not modified in response to a |:cd|
+			command.
+	both:		When using ":e bufname" and already editing "bufname"
+			the buffer is made empty and autocommands are
+			triggered as usual for |:edit|.
+							*E676*
+	"acwrite" implies that the buffer name is not related to a file, like
+	"nofile", but it will be written.  Thus, in contrast to "nofile" and
+	"nowrite", ":w" does work and a modified buffer can't be abandoned
+	without saving.  For writing there must be matching |BufWriteCmd|,
+	|FileWriteCmd| or |FileAppendCmd| autocommands.
+
+						*'casemap'* *'cmp'*
+'casemap' 'cmp'		string	(default: "internal,keepascii")
+			global
+	Specifies details about changing the case of letters.  It may contain
+	these words, separated by a comma:
+	internal	Use internal case mapping functions, the current
+			locale does not change the case mapping.  This only
+			matters when 'encoding' is a Unicode encoding,
+			"latin1" or "iso-8859-15".  When "internal" is
+			omitted, the towupper() and towlower() system library
+			functions are used when available.
+	keepascii	For the ASCII characters (0x00 to 0x7f) use the US
+			case mapping, the current locale is not effective.
+			This probably only matters for Turkish.
+
+				*'cdhome'* *'cdh'* *'nocdhome'* *'nocdh'*
+'cdhome' 'cdh'		boolean	(default: off)
+			global
+	When on, |:cd|, |:tcd| and |:lcd| without an argument changes the
+	current working directory to the |$HOME| directory like in Unix.
+	When off, those commands just print the current directory name.
+	On Unix this option has no effect.
+	NOTE: This option is reset when 'compatible' is set.
+
+						*'cdpath'* *'cd'* *E344* *E346*
+'cdpath' 'cd'		string	(default: equivalent to $CDPATH or ",,")
+			global
+	This is a list of directories which will be searched when using the
+	|:cd|, |:tcd| and |:lcd| commands, provided that the directory being
+	searched for has a relative path, not an absolute part starting with
+	"/", "./" or "../", the 'cdpath' option is not used then.
+	The 'cdpath' option's value has the same form and semantics as
+	|'path'|.  Also see |file-searching|.
+	The default value is taken from $CDPATH, with a "," prepended to look
+	in the current directory first.
+	If the default value taken from $CDPATH is not what you want, include
+	a modified version of the following command in your vimrc file to
+	override it: >
+	  :let &cdpath = ',' .. substitute(substitute($CDPATH, '[, ]', '\\\0', 'g'), ':', ',', 'g')
+<	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+	(parts of 'cdpath' can be passed to the shell to expand file names).
+
+						*'cedit'*
+'cedit'			string	(Vi default: "", Vim default: CTRL-F)
+			global
+	The key used in Command-line Mode to open the command-line window.
+	The default is CTRL-F when 'compatible' is off.
+	Only non-printable keys are allowed.
+	The key can be specified as a single character, but it is difficult to
+	type.  The preferred way is to use the <> notation.  Examples: >
+		:exe "set cedit=\<C-Y>"
+		:exe "set cedit=\<Esc>"
+<	|Nvi| also has this option, but it only uses the first character.
+	See |cmdwin|.
+	NOTE: This option is set to the Vim default value when 'compatible'
+	is reset.
+
+				*'charconvert'* *'ccv'* *E202* *E214* *E513*
+'charconvert' 'ccv'	string (default "")
+			global
+			{only available when compiled with the |+eval| feature}
+	An expression that is used for character encoding conversion.  It is
+	evaluated when a file that is to be read or has been written has a
+	different encoding from what is desired.
+	'charconvert' is not used when the internal iconv() function is
+	supported and is able to do the conversion.  Using iconv() is
+	preferred, because it is much faster.
+	'charconvert' is not used when reading stdin |--|, because there is no
+	file to convert from.  You will have to save the text in a file first.
+	The expression must return zero, false or an empty string for success,
+	non-zero or true for failure.
+	The possible encoding names encountered are in 'encoding'.
+	Additionally, names given in 'fileencodings' and 'fileencoding' are
+	used.
+	Conversion between "latin1", "unicode", "ucs-2", "ucs-4" and "utf-8"
+	is done internally by Vim, 'charconvert' is not used for this.
+	'charconvert' is also used to convert the viminfo file, if the 'c'
+	flag is present in 'viminfo'.  Also used for Unicode conversion.
+	Example: >
+		set charconvert=CharConvert()
+		fun CharConvert()
+		  system("recode "
+			\ .. v:charconvert_from .. ".." .. v:charconvert_to
+			\ .. " <" .. v:fname_in .. " >" .. v:fname_out)
+		  return v:shell_error
+		endfun
+<	The related Vim variables are:
+		v:charconvert_from	name of the current encoding
+		v:charconvert_to	name of the desired encoding
+		v:fname_in		name of the input file
+		v:fname_out		name of the output file
+	Note that v:fname_in and v:fname_out will never be the same.
+	Note that v:charconvert_from and v:charconvert_to may be different
+	from 'encoding'.  Vim internally uses UTF-8 instead of UCS-2 or UCS-4.
+
+	The advantage of using a function call without arguments is that it is
+	faster, see |expr-option-function|.
+
+	Encryption is not done by Vim when using 'charconvert'.  If you want
+	to encrypt the file after conversion, 'charconvert' should take care
+	of this.
+
+	If the 'charconvert' expression starts with s: or |<SID>|, then it is
+	replaced with the script ID (|local-function|). Example: >
+		set charconvert=s:MyConvert()
+		set charconvert=<SID>SomeConvert()
+<	Otherwise the expression is evaluated in the context of the script
+	where the option was set, thus script-local items are available.
+
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+				   *'cindent'* *'cin'* *'nocindent'* *'nocin'*
+'cindent' 'cin'		boolean	(default off)
+			local to buffer
+	Enables automatic C program indenting.  See 'cinkeys' to set the keys
+	that trigger reindenting in insert mode and 'cinoptions' to set your
+	preferred indent style.
+	If 'indentexpr' is not empty, it overrules 'cindent'.
+	If 'lisp' is not on and both 'indentexpr' and 'equalprg' are empty,
+	the "=" operator indents using this algorithm rather than calling an
+	external program.
+	See |C-indenting|.
+	When you don't like the way 'cindent' works, try the 'smartindent'
+	option or 'indentexpr'.
+	This option is not used when 'paste' is set.
+	NOTE: This option is reset when 'compatible' is set.
+
+							*'cinkeys'* *'cink'*
+'cinkeys' 'cink'	string	(default "0{,0},0),0],:,0#,!^F,o,O,e")
+			local to buffer
+	A list of keys that, when typed in Insert mode, cause reindenting of
+	the current line.  Only used if 'cindent' is on and 'indentexpr' is
+	empty.
+	For the format of this option see |cinkeys-format|.
+	See |C-indenting|.
+
+						*'cinoptions'* *'cino'*
+'cinoptions' 'cino'	string	(default "")
+			local to buffer
+	The 'cinoptions' affect the way 'cindent' reindents lines in a C
+	program.  See |cinoptions-values| for the values of this option, and
+	|C-indenting| for info on C indenting in general.
+
+
+						*'cinwords'* *'cinw'*
+'cinwords' 'cinw'	string	(default "if,else,while,do,for,switch")
+			local to buffer
+	These keywords start an extra indent in the next line when
+	'smartindent' or 'cindent' is set.  For 'cindent' this is only done at
+	an appropriate place (inside {}).
+	Note that 'ignorecase' isn't used for 'cinwords'.  If case doesn't
+	matter, include the keyword both the uppercase and lowercase:
+	"if,If,IF".
+
+						*'cinscopedecls'* *'cinsd'*
+'cinscopedecls' 'cinsd'	string	(default "public,protected,private")
+			local to buffer
+	Keywords that are interpreted as a C++ scope declaration by |cino-g|.
+	Useful e.g. for working with the Qt framework that defines additional
+	scope declarations "signals", "public slots" and "private slots": >
+		set cinscopedecls+=signals,public\ slots,private\ slots
+
+<						*'clipboard'* *'cb'*
+'clipboard' 'cb'	string	(default "autoselect,exclude:cons\|linux"
+						  for X-windows, "" otherwise)
+			global
+			{only in GUI versions or when the |+xterm_clipboard|
+			feature is included}
+	This option is a list of comma-separated names.
+	Note: if one of the items is "exclude:", then you can't add an item
+	after that.  Therefore do not append an item with += but use ^= to
+	prepend, e.g.: >
+		set clipboard^=unnamed
+<	When using the GUI see |'go-A'|.
+	These names are recognized:
+
+						*clipboard-unnamed*
+	unnamed		When included, Vim will use the clipboard register '*'
+			for all yank, delete, change and put operations which
+			would normally go to the unnamed register.  When a
+			register is explicitly specified, it will always be
+			used regardless of whether "unnamed" is in 'clipboard'
+			or not.  The clipboard register can always be
+			explicitly accessed using the "* notation.  Also see
+			|gui-clipboard|.
+
+						*clipboard-unnamedplus*
+	unnamedplus	A variant of the "unnamed" flag which uses the
+			clipboard register '+' (|quoteplus|) instead of
+			register '*' for all yank, delete, change and put
+			operations which would normally go to the unnamed
+			register.  When "unnamed" is also included to the
+			option, yank operations (but not delete, change or
+			put) will additionally copy the text into register
+			'*'.
+			Only available with the |+X11| feature.
+			Availability can be checked with: >
+				if has('unnamedplus')
+<
+						*clipboard-autoselect*
+	autoselect	Works like the 'a' flag in 'guioptions': If present,
+			then whenever Visual mode is started, or the Visual
+			area extended, Vim tries to become the owner of the
+			windowing system's global selection or put the
+			selected text on the clipboard used by the selection
+			register "*.  See |'go-a'| and |quotestar| for details.
+			When the GUI is active, the 'a' flag in 'guioptions'
+			is used, when the GUI is not active, this "autoselect"
+			flag is used.
+			Also applies to the modeless selection.
+
+						*clipboard-autoselectplus*
+	autoselectplus  Like "autoselect" but using the + register instead of
+			the * register.  Compare to the 'P' flag in
+			'guioptions'.
+
+						*clipboard-autoselectml*
+	autoselectml	Like "autoselect", but for the modeless selection
+			only.  Compare to the 'A' flag in 'guioptions'.
+
+						*clipboard-html*
+	html		When the clipboard contains HTML, use this when
+			pasting.  When putting text on the clipboard, mark it
+			as HTML.  This works to copy rendered HTML from
+			Firefox, paste it as raw HTML in Vim, select the HTML
+			in Vim and paste it in a rich edit box in Firefox.
+			You probably want to add this only temporarily,
+			possibly use BufEnter autocommands.
+			Only supported for GTK version 2 and later.
+
+						*clipboard-exclude*
+	exclude:{pattern}
+			Defines a pattern that is matched against the name of
+			the terminal 'term'.  If there is a match, no
+			connection will be made to the X server.  This is
+			useful in this situation:
+			- Running Vim in a console.
+			- $DISPLAY is set to start applications on another
+			  display.
+			- You do not want to connect to the X server in the
+			  console, but do want this in a terminal emulator.
+			To never connect to the X server use: >
+				exclude:.*
+<			This has the same effect as using the |-X| argument.
+			Note that when there is no connection to the X server
+			the window title won't be restored and the clipboard
+			cannot be accessed.
+			The value of 'magic' is ignored, {pattern} is
+			interpreted as if 'magic' was on.
+			The rest of the option value will be used for
+			{pattern}, this must be the last entry.
+
+						*'cmdheight'* *'ch'*
+'cmdheight' 'ch'	number	(default 1)
+			global or local to tab page
+	Number of screen lines to use for the command-line.  A larger value
+	helps avoiding |hit-enter| prompts.
+	The value of this option is stored with the tab page, so that each tab
+	page can have a different value.
+
+						*'cmdwinheight'* *'cwh'*
+'cmdwinheight' 'cwh'	number	(default 7)
+			global
+	Number of screen lines to use for the command-line window. |cmdwin|
+
+						*'colorcolumn'* *'cc'*
+'colorcolumn' 'cc'	string	(default "")
+			local to window
+			{not available when compiled without the |+syntax|
+			feature}
+	'colorcolumn' is a comma-separated list of screen columns that are
+	highlighted with ColorColumn |hl-ColorColumn|.  Useful to align
+	text.  Will make screen redrawing slower.
+	The screen column can be an absolute number, or a number preceded with
+	'+' or '-', which is added to or subtracted from 'textwidth'. >
+
+		:set cc=+1	  " highlight column after 'textwidth'
+		:set cc=+1,+2,+3  " highlight three columns after 'textwidth'
+		:hi ColorColumn ctermbg=lightgrey guibg=lightgrey
+<
+	When 'textwidth' is zero then the items with '-' and '+' are not used.
+	A maximum of 256 columns are highlighted.
+
+						*'columns'* *'co'* *E594*
+'columns' 'co'		number	(default 80 or terminal width)
+			global
+	Number of columns of the screen.  Normally this is set by the terminal
+	initialization and does not have to be set by hand.  Also see
+	|posix-screen-size|.
+	When Vim is running in the GUI or in a resizable window, setting this
+	option will cause the window size to be changed.  When you only want
+	to use the size for the GUI, put the command in your |gvimrc| file.
+	When you set this option and Vim is unable to change the physical
+	number of columns of the display, the display may be messed up.  For
+	the GUI it is always possible and Vim limits the number of columns to
+	what fits on the screen.  You can use this command to get the widest
+	window possible: >
+		:set columns=9999
+<	Minimum value is 12, maximum value is 10000.
+
+					*'comments'* *'com'* *E524* *E525*
+'comments' 'com'	string	(default
+				"s1:/*,mb:*,ex:*/,://,b:#,:%,:XCOMM,n:>,fb:-")
+			local to buffer
+	A comma-separated list of strings that can start a comment line.  See
+	|format-comments|.  See |option-backslash| about using backslashes to
+	insert a space.
+
+					*'commentstring'* *'cms'* *E537*
+'commentstring' 'cms'	string	(default "/*%s*/")
+			local to buffer
+			{not available when compiled without the |+folding|
+			feature}
+	A template for a comment.  The "%s" in the value is replaced with the
+	comment text.  Currently only used to add markers for folding, see
+	|fold-marker|.
+
+			*'compatible'* *'cp'* *'nocompatible'* *'nocp'*
+'compatible' 'cp'	boolean	(default on, off when a |vimrc| or |gvimrc|
+					file is found, reset in |defaults.vim|)
+			global
+	This option has the effect of making Vim either more Vi-compatible, or
+	make Vim behave in a more useful way.
+
+	This is a special kind of option, because when it's set or reset,
+	other options are also changed as a side effect.
+	NOTE: Setting or resetting this option can have a lot of unexpected
+	effects: Mappings are interpreted in another way, undo behaves
+	differently, etc.  If you set this option in your vimrc file, you
+	should probably put it at the very start.
+
+	By default this option is on and the Vi defaults are used for the
+	options.  This default was chosen for those people who want to use Vim
+	just like Vi, and don't even (want to) know about the 'compatible'
+	option.
+	When a |vimrc| or |gvimrc| file is found while Vim is starting up,
+	this option is switched off, and all options that have not been
+	modified will be set to the Vim defaults.  Effectively, this means
+	that when a |vimrc| or |gvimrc| file exists, Vim will use the Vim
+	defaults, otherwise it will use the Vi defaults.  (Note: This doesn't
+	happen for the system-wide vimrc or gvimrc file, nor for a file given
+	with the |-u| argument).  Also see |compatible-default| and
+	|posix-compliance|.
+	You can also set this option with the "-C" argument, and reset it with
+	"-N".  See |-C| and |-N|.
+	See 'cpoptions' for more fine tuning of Vi compatibility.
+
+	When this option is set, numerous other options are set to make Vim as
+	Vi-compatible as possible.  When this option is unset, various options
+	are set to make Vim more useful.  The table below lists all the
+	options affected.
+	The {?} column indicates when the options are affected:
+	+  Means that the option is set to the value given in {set value} when

+	&  Means that the option is set to the value given in {set value} when
+	   'compatible' is set AND is set to its Vim default value when
+	   'compatible' is unset.
+	-  Means the option is NOT changed when setting 'compatible' but IS
+	   set to its Vim default when 'compatible' is unset.
+	The {effect} column summarises the change when 'compatible' is set.

+
+						*'complete'* *'cpt'* *E535*
+'complete' 'cpt'	string	(default: ".,w,b,u,t,i")
+			local to buffer
+	This option specifies how keyword completion |ins-completion| works
+	when CTRL-P or CTRL-N are used.  It is also used for whole-line
+	completion |i_CTRL-X_CTRL-L|.  It indicates the type of completion
+	and the places to scan.  It is a comma-separated list of flags:
+	.	scan the current buffer ('wrapscan' is ignored)
+	w	scan buffers from other windows
+	b	scan other loaded buffers that are in the buffer list
+	u	scan the unloaded buffers that are in the buffer list
+	U	scan the buffers that are not in the buffer list
+	k	scan the files given with the 'dictionary' option
+	kspell  use the currently active spell checking |spell|
+	k{dict}	scan the file {dict}.  Several "k" flags can be given,
+		patterns are valid too.  For example: >
+			:set cpt=k/usr/dict/*,k~/spanish
+<	s	scan the files given with the 'thesaurus' option
+	s{tsr}	scan the file {tsr}.  Several "s" flags can be given, patterns
+		are valid too.
+	i	scan current and included files
+	d	scan current and included files for defined name or macro
+		|i_CTRL-X_CTRL-D|
+	]	tag completion
+	t	same as "]"
+
+	Unloaded buffers are not loaded, thus their autocmds |:autocmd| are
+	not executed, this may lead to unexpected completions from some files
+	(gzipped files for example).  Unloaded buffers are not scanned for
+	whole-line completion.
+
+	The default is ".,w,b,u,t,i", which means to scan:
+	   1. the current buffer
+	   2. buffers in other windows
+	   3. other loaded buffers
+	   4. unloaded buffers
+	   5. tags
+	   6. included files
+
+	As you can see, CTRL-N and CTRL-P can be used to do any 'iskeyword'-
+	based expansion (e.g., dictionary |i_CTRL-X_CTRL-K|, included patterns
+	|i_CTRL-X_CTRL-I|, tags |i_CTRL-X_CTRL-]| and normal expansions).
+
+						*'completefunc'* *'cfu'*
+'completefunc' 'cfu'	string	(default: empty)
+			local to buffer
+			{not available when compiled without the |+eval|
+			feature}
+	This option specifies a function to be used for Insert mode completion
+	with CTRL-X CTRL-U. |i_CTRL-X_CTRL-U|
+	See |complete-functions| for an explanation of how the function is
+	invoked and what it should return.  The value can be the name of a
+	function, a |lambda| or a |Funcref|. See |option-value-function| for
+	more information.
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+						*'completeslash'* *'csl'*
+'completeslash' 'csl'	string	(default: "")
+			local to buffer
+			{only for MS-Windows}
+	When this option is set it overrules 'shellslash' for completion:
+	- When this option is set to "slash", a forward slash is used for path
+	  completion in insert mode. This is useful when editing HTML tag, or
+	  Makefile with 'noshellslash' on MS-Windows.
+	- When this option is set to "backslash", backslash is used. This is
+	  useful when editing a batch file with 'shellslash' set on MS-Windows.
+	- When this option is empty, same character is used as for
+	  'shellslash'.
+	For Insert mode completion the buffer-local value is used.  For
+	command line completion the global value is used.
+
+						*'completeopt'* *'cot'*
+'completeopt' 'cot'	string	(default: "menu,preview")
+			global
+	A comma-separated list of options for Insert mode completion
+	|ins-completion|.  The supported values are:
+
+	   menu	    Use a popup menu to show the possible completions.  The
+		    menu is only shown when there is more than one match and
+		    sufficient colors are available.  |ins-completion-menu|
+
+	   menuone  Use the popup menu also when there is only one match.
+		    Useful when there is additional information about the
+		    match, e.g., what file it comes from.
+
+	   longest  Only insert the longest common text of the matches.  If
+		    the menu is displayed you can use CTRL-L to add more
+		    characters.  Whether case is ignored depends on the kind
+		    of completion.  For buffer text the 'ignorecase' option is
+		    used.
+
+	   preview  Show extra information about the currently selected
+		    completion in the preview window.  Only works in
+		    combination with "menu" or "menuone".
+
+	   popup    Show extra information about the currently selected
+		    completion in a popup window.  Only works in combination
+		    with "menu" or "menuone".  Overrides "preview".
+		    See |'completepopup'| for specifying properties.
+		    {only works when compiled with the |+textprop| feature}
+
+	   popuphidden
+		    Just like "popup" but initially hide the popup.  Use a
+		    |CompleteChanged| autocommand to fetch the info and call
+		    |popup_show()| once the popup has been filled.
+		    See the example at |complete-popuphidden|.
+		    {only works when compiled with the |+textprop| feature}
+
+	   noinsert Do not insert any text for a match until the user selects
+		    a match from the menu. Only works in combination with
+		    "menu" or "menuone". No effect if "longest" is present.
+
+	   noselect Do not select a match in the menu, force the user to
+		    select one from the menu. Only works in combination with
+		    "menu" or "menuone".
+
+
+					*'completepopup'* *'cpp'*
+'completepopup' 'cpp'	string (default empty)
+			global
+			{not available when compiled without the |+textprop|
+			or |+quickfix| feature}
+	When 'completeopt' contains "popup" then this option is used for the
+	properties of the info popup when it is created.  If an info popup
+	window already exists it is closed, so that the option value is
+	applied when it is created again.
+	You can also use |popup_findinfo()| and then set properties for an
+	existing info popup with |popup_setoptions()|.  See |complete-popup|.
+
+
+						*'concealcursor'* *'cocu'*
+'concealcursor' 'cocu'	string (default: "")
+			local to window
+			{not available when compiled without the |+conceal|
+			feature}
+	Sets the modes in which text in the cursor line can also be concealed.
+	When the current mode is listed then concealing happens just like in
+	other lines.
+	  n		Normal mode
+	  v		Visual mode
+	  i		Insert mode
+	  c		Command line editing, for 'incsearch'
+
+	'v' applies to all lines in the Visual area, not only the cursor.
+	A useful value is "nc".  This is used in help files.  So long as you
+	are moving around text is concealed, but when starting to insert text
+	or selecting a Visual area the concealed text is displayed, so that
+	you can see what you are doing.
+	Keep in mind that the cursor position is not always where it's
+	displayed.  E.g., when moving vertically it may change column.
+
+
+						*'conceallevel'* *'cole'*
+'conceallevel' 'cole'	number (default 0)
+			local to window
+			{not available when compiled without the |+conceal|
+			feature}
+	Determine how text with the "conceal" syntax attribute |:syn-conceal|
+	is shown:
+
+	Value		Effect ~
+	0		Text is shown normally
+	1		Each block of concealed text is replaced with one
+			character.  If the syntax item does not have a custom
+			replacement character defined (see |:syn-cchar|) the
+			character defined in 'listchars' is used (default is a
+			space).
+			It is highlighted with the "Conceal" highlight group.
+	2		Concealed text is completely hidden unless it has a
+			custom replacement character defined (see
+			|:syn-cchar|).
+	3		Concealed text is completely hidden.
+
+	Note: in the cursor line concealed text is not hidden, so that you can
+	edit and copy the text.  This can be changed with the 'concealcursor'
+	option.
+
+				*'confirm'* *'cf'* *'noconfirm'* *'nocf'*
+'confirm' 'cf'		boolean (default off)
+			global
+	When 'confirm' is on, certain operations that would normally
+	fail because of unsaved changes to a buffer, e.g. ":q" and ":e",
+	instead raise a |dialog| asking if you wish to save the current
+	file(s).  You can still use a ! to unconditionally |abandon| a buffer.
+	If 'confirm' is off you can still activate confirmation for one
+	command only (this is most useful in mappings) with the |:confirm|
+	command.
+	Also see the |confirm()| function and the 'v' flag in 'guioptions'.
+
+			*'conskey'* *'consk'* *'noconskey'* *'noconsk'*
+'conskey' 'consk'	boolean	(default off)
+			global
+	This was for MS-DOS and is no longer supported.
+
+			*'copyindent'* *'ci'* *'nocopyindent'* *'noci'*
+'copyindent' 'ci'	boolean	(default off)
+			local to buffer
+	Copy the structure of the existing lines indent when autoindenting a
+	new line.  Normally the new indent is reconstructed by a series of
+	tabs followed by spaces as required (unless |'expandtab'| is enabled,
+	in which case only spaces are used).  Enabling this option makes the
+	new line copy whatever characters were used for indenting on the
+	existing line.  'expandtab' has no effect on these characters, a Tab
+	remains a Tab.  If the new indent is greater than on the existing
+	line, the remaining space is filled in the normal manner.
+	NOTE: This option is reset when 'compatible' is set.
+	Also see 'preserveindent'.
+
+						*'cpoptions'* *'cpo'* *cpo*
+'cpoptions' 'cpo'	string	(Vim default: "aABceFs",
+				 Vi default:  all flags)
+			global
+	A sequence of single character flags.  When a character is present
+	this indicates Vi-compatible behavior.  This is used for things where
+	not being Vi-compatible is mostly or sometimes preferred.
+	'cpoptions' stands for "compatible-options".
+	Commas can be added for readability.
+	To avoid problems with flags that are added in the future, use the
+	"+=" and "-=" feature of ":set" |add-option-flags|.
+
+	NOTE: This option is set to the Vi default value when 'compatible' is
+	set and to the Vim default value when 'compatible' is reset.
+
+	NOTE: In a |Vim9| script, when `vim9script` is encountered, the value
+	is saved, 'cpoptions' is set to the Vim default, and the saved value
+	is restored at the end of the script.  Changes to the value of
+	'cpoptions' will be applied to the saved value, but keep in mind that
+	removing a flag that is not present when 'cpoptions' is changed has no
+	effect.  In the |.vimrc| file the value is not restored, thus using
+	`vim9script` in the |.vimrc| file results in using the Vim default.
+
+	NOTE: This option is set to the POSIX default value at startup when
+	the Vi default value would be used and the $VIM_POSIX environment
+	variable exists |posix|.  This means Vim tries to behave like the
+	POSIX specification.
+
+	    contains	behavior	~
+								*cpo-a*
+		a	When included, a ":read" command with a file name
+			argument will set the alternate file name for the
+			current window.
+								*cpo-A*
+		A	When included, a ":write" command with a file name
+			argument will set the alternate file name for the
+			current window.
+								*cpo-b*
+		b	"\|" in a ":map" command is recognized as the end of
+			the map command.  The '\' is included in the mapping,
+			the text after the '|' is interpreted as the next
+			command.  Use a CTRL-V instead of a backslash to
+			include the '|' in the mapping.  Applies to all
+			mapping, abbreviation, menu and autocmd commands.
+			See also |map_bar|.
+								*cpo-B*
+		B	A backslash has no special meaning in mappings,
+			abbreviations, user commands and the "to" part of the
+			menu commands.  Remove this flag to be able to use a
+			backslash like a CTRL-V.  For example, the command
+			":map X \<Esc>" results in X being mapped to:
+				'B' included:	"\^["	 (^[ is a real <Esc>)
+				'B' excluded:	"<Esc>"  (5 characters)
+				('<' excluded in both cases)
+								*cpo-c*
+		c	Searching continues at the end of any match at the
+			cursor position, but not further than the start of the
+			next line.  When not present searching continues
+			one character from the cursor position.  With 'c'
+			"abababababab" only gets three matches when repeating
+			"/abab", without 'c' there are five matches.
+								*cpo-C*
+		C	Do not concatenate sourced lines that start with a
+			backslash.  See |line-continuation|.
+								*cpo-d*
+		d	Using "./" in the 'tags' option doesn't mean to use
+			the tags file relative to the current file, but the
+			tags file in the current directory.
+								*cpo-D*
+		D	Can't use CTRL-K to enter a digraph after Normal mode
+			commands with a character argument, like |r|, |f| and
+			|t|.
+								*cpo-e*
+		e	When executing a register with ":@r", always add a
+			<CR> to the last line, also when the register is not
+			linewise.  If this flag is not present, the register
+			is not linewise and the last line does not end in a
+			<CR>, then the last line is put on the command-line
+			and can be edited before hitting <CR>.
+								*cpo-E*
+		E	It is an error when using "y", "d", "c", "g~", "gu" or
+			"gU" on an Empty region.  The operators only work when
+			at least one character is to be operated on.  Example:
+			This makes "y0" fail in the first column.
+								*cpo-f*
+		f	When included, a ":read" command with a file name
+			argument will set the file name for the current buffer,
+			if the current buffer doesn't have a file name yet.
+								*cpo-F*
+		F	When included, a ":write" command with a file name
+			argument will set the file name for the current
+			buffer, if the current buffer doesn't have a file name
+			yet.  Also see |cpo-P|.
+								*cpo-g*
+		g	Goto line 1 when using ":edit" without argument.
+								*cpo-H*
+		H	When using "I" on a line with only blanks, insert
+			before the last blank.  Without this flag insert after
+			the last blank.
+								*cpo-i*
+		i	When included, interrupting the reading of a file will
+			leave it modified.
+								*cpo-I*
+		I	When moving the cursor up or down just after inserting
+			indent for 'autoindent', do not delete the indent.
+								*cpo-j*
+		j	When joining lines, only add two spaces after a '.',
+			not after '!' or '?'.  Also see 'joinspaces'.
+								*cpo-J*
+		J	A |sentence| has to be followed by two spaces after
+			the '.', '!' or '?'.  A <Tab> is not recognized as
+			white space.
+								*cpo-k*
+		k	Disable the recognition of raw key codes in
+			mappings, abbreviations, and the "to" part of menu
+			commands.  For example, if <Key> sends ^[OA (where ^[
+			is <Esc>), the command ":map X ^[OA" results in X
+			being mapped to:
+				'k' included:	"^[OA"	 (3 characters)
+				'k' excluded:	"<Key>"  (one key code)
+			Also see the '<' flag below.
+								*cpo-K*
+		K	Don't wait for a key code to complete when it is
+			halfway a mapping.  This breaks mapping <F1><F1> when
+			only part of the second <F1> has been read.  It
+			enables cancelling the mapping by typing <F1><Esc>.
+								*cpo-l*
+		l	Backslash in a [] range in a search pattern is taken
+			literally, only "\]", "\^", "\-" and "\\" are special.
+			See |/[]|
+			   'l' included: "/[ \t]"  finds <Space>, '\' and 't'
+			   'l' excluded: "/[ \t]"  finds <Space> and <Tab>
+			Also see |cpo-\|.
+								*cpo-L*
+		L	When the 'list' option is set, 'wrapmargin',
+			'textwidth', 'softtabstop' and Virtual Replace mode
+			(see |gR|) count a <Tab> as two characters, instead of
+			the normal behavior of a <Tab>.
+								*cpo-m*
+		m	When included, a showmatch will always wait half a
+			second.  When not included, a showmatch will wait half
+			a second or until a character is typed.  |'showmatch'|
+								*cpo-M*
+		M	When excluded, "%" matching will take backslashes into
+			account.  Thus in "( \( )" and "\( ( \)" the outer
+			parenthesis match.  When included "%" ignores
+			backslashes, which is Vi compatible.
+								*cpo-n*
+		n	When included, the column used for 'number' and
+			'relativenumber' will also be used for text of wrapped
+			lines.
+								*cpo-o*
+		o	Line offset to search command is not remembered for
+			next search.
+								*cpo-O*
+		O	Don't complain if a file is being overwritten, even
+			when it didn't exist when editing it.  This is a
+			protection against a file unexpectedly created by
+			someone else.  Vi didn't complain about this.
+								*cpo-p*
+		p	Vi compatible Lisp indenting.  When not present, a
+			slightly better algorithm is used.
+								*cpo-P*
+		P	When included, a ":write" command that appends to a
+			file will set the file name for the current buffer, if
+			the current buffer doesn't have a file name yet and
+			the 'F' flag is also included |cpo-F|.
+								*cpo-q*
+		q	When joining multiple lines leave the cursor at the
+			position where it would be when joining two lines.
+								*cpo-r*
+		r	Redo ("." command) uses "/" to repeat a search
+			command, instead of the actually used search string.
+								*cpo-R*
+		R	Remove marks from filtered lines.  Without this flag
+			marks are kept like |:keepmarks| was used.
+								*cpo-s*
+		s	Set buffer options when entering the buffer for the
+			first time.  This is like it is in Vim version 3.0.
+			And it is the default.  If not present the options are
+			set when the buffer is created.
+								*cpo-S*
+		S	Set buffer options always when entering a buffer
+			(except 'readonly', 'fileformat', 'filetype' and
+			'syntax').  This is the (most) Vi compatible setting.
+			The options are set to the values in the current
+			buffer.  When you change an option and go to another
+			buffer, the value is copied.  Effectively makes the
+			buffer options global to all buffers.
+
+			's'    'S'     copy buffer options
+			no     no      when buffer created
+			yes    no      when buffer first entered (default)
+			 X     yes     each time when buffer entered (vi comp.)
+								*cpo-t*
+		t	Search pattern for the tag command is remembered for
+			"n" command.  Otherwise Vim only puts the pattern in
+			the history for search pattern, but doesn't change the
+			last used search pattern.
+								*cpo-u*
+		u	Undo is Vi compatible.  See |undo-two-ways|.
+								*cpo-v*
+		v	Backspaced characters remain visible on the screen in
+			Insert mode.  Without this flag the characters are
+			erased from the screen right away.  With this flag the
+			screen newly typed text overwrites backspaced
+			characters.
+								*cpo-w*
+		w	When using "cw" on a blank character, only change one
+			character and not all blanks until the start of the
+			next word.
+								*cpo-W*
+		W	Don't overwrite a readonly file.  When omitted, ":w!"
+			overwrites a readonly file, if possible.
+								*cpo-x*
+		x	<Esc> on the command-line executes the command-line.
+			The default in Vim is to abandon the command-line,
+			because <Esc> normally aborts a command.  |c_<Esc>|
+								*cpo-X*
+		X	When using a count with "R" the replaced text is
+			deleted only once.  Also when repeating "R" with "."
+			and a count.
+								*cpo-y*
+		y	A yank command can be redone with ".".  Think twice if
+			you really want to use this, it may break some
+			plugins, since most people expect "." to only repeat a
+			change.
+								*cpo-Z*
+		Z	When using "w!" while the 'readonly' option is set,
+			don't reset 'readonly'.
+								*cpo-!*
+		!	When redoing a filter command, use the last used
+			external command, whatever it was.  Otherwise the last
+			used -filter- command is used.
+								*cpo-$*
+		$	When making a change to one line, don't redisplay the
+			line, but put a '$' at the end of the changed text.
+			The changed text will be overwritten when you type the
+			new text.  The line is redisplayed if you type any
+			command that moves the cursor from the insertion
+			point.
+								*cpo-%*
+		%	Vi-compatible matching is done for the "%" command.
+			Does not recognize "#if", "#endif", etc.
+			Does not recognize "/*" and "*/".
+			Parens inside single and double quotes are also
+			counted, causing a string that contains a paren to
+			disturb the matching.  For example, in a line like
+			"if (strcmp("foo(", s))" the first paren does not
+			match the last one.  When this flag is not included,
+			parens inside single and double quotes are treated
+			specially.  When matching a paren outside of quotes,
+			everything inside quotes is ignored.  When matching a
+			paren inside quotes, it will find the matching one (if
+			there is one).  This works very well for C programs.
+			This flag is also used for other features, such as
+			C-indenting.
+								*cpo--*
+		-	When included, a vertical movement command fails when
+			it would go above the first line or below the last
+			line.  Without it the cursor moves to the first or
+			last line, unless it already was in that line.
+			Applies to the commands "-", "k", CTRL-P, "+", "j",
+			CTRL-N, CTRL-J and ":1234".
+								*cpo-+*
+		+	When included, a ":write file" command will reset the
+			'modified' flag of the buffer, even though the buffer
+			itself may still be different from its file.
+								*cpo-star*
+		*	Use ":*" in the same way as ":@".  When not included,
+			":*" is an alias for ":'<,'>", select the Visual area.
+								*cpo-<*
+		<	Disable the recognition of special key codes in |<>|
+			form in mappings, abbreviations, and the "to" part of
+			menu commands.  For example, the command
+			":map X <Tab>" results in X being mapped to:
+				'<' included:	"<Tab>"  (5 characters)
+				'<' excluded:	"^I"	 (^I is a real <Tab>)
+			Also see the 'k' flag above.
+								*cpo->*
+		>	When appending to a register, put a line break before
+			the appended text.
+								*cpo-;*
+		;	When using |,| or |;| to repeat the last |t| search
+			and the cursor is right in front of the searched
+			character, the cursor won't move. When not included,
+			the cursor would skip over it and jump to the
+			following occurrence.
+
+	POSIX flags.  These are not included in the Vi default value, except
+	when $VIM_POSIX was set on startup. |posix|
+
+	    contains	behavior	~
+								*cpo-#*
+		#	A count before "D", "o" and "O" has no effect.
+								*cpo-&*
+		&	When ":preserve" was used keep the swap file when
+			exiting normally while this buffer is still loaded.
+			This flag is tested when exiting.
+								*cpo-\*
+		\	Backslash in a [] range in a search pattern is taken
+			literally, only "\]" is special  See |/[]|
+			   '\' included: "/[ \-]"  finds <Space>, '\' and '-'
+			   '\' excluded: "/[ \-]"  finds <Space> and '-'
+			Also see |cpo-l|.
+								*cpo-/*
+		/	When "%" is used as the replacement string in a |:s|
+			command, use the previous replacement string. |:s%|
+								*cpo-{*
+		{	The |{| and |}| commands also stop at a "{" character
+			at the start of a line.
+								*cpo-.*
+		.	The ":chdir" and ":cd" commands fail if the current
+			buffer is modified, unless ! is used.  Vim doesn't
+			need this, since it remembers the full path of an
+			opened file.
+								*cpo-bar*
+		|	The value of the $LINES and $COLUMNS environment
+			variables overrule the terminal size values obtained
+			with system specific functions.
+
+
+						*'cryptmethod'* *'cm'*
+'cryptmethod' 'cm'	string	(default "blowfish2")
+			global or local to buffer |global-local|
+	Method used for encryption when the buffer is written to a file:
+							*pkzip*
+	   zip		PkZip compatible method.  A weak kind of encryption.
+			Backwards compatible with Vim 7.2 and older.
+			Only use if you need to be backwards compatible.
+							*blowfish*
+	   blowfish	Blowfish method.  Medium strong encryption but it has
+			an implementation flaw.  Requires Vim 7.3 or later,
+			files can NOT be read by Vim 7.2 and older.  This adds
+			a "seed" to the file, every time you write the file
+			the encrypted bytes will be different.
+			Obsolete, please do no longer use.
+							*blowfish2*
+	   blowfish2	Blowfish method.  Medium strong encryption.  Requires
+			Vim 7.4.401 or later, files can NOT be read by Vim 7.3
+			and older.  This adds a "seed" to the file, every time
+			you write the file the encrypted bytes will be
+			different.  The whole undo file is encrypted, not just
+			the pieces of text.
+					*E1193* *E1194* *E1195* *E1196* *E1230*
+					*E1197* *E1198* *E1199* *E1200* *E1201*
+	   xchacha20	XChaCha20 Cipher with Poly1305 Message Authentication
+			Code.  Medium strong till strong encryption.
+			Encryption is provided by the libsodium library, it
+			requires Vim to be built with |+sodium|.
+			It adds a seed and a message authentication code (MAC)
+			to the file.  This needs at least a Vim 8.2.3022 to
+			read the encrypted file.
+			Encryption of swap files is not supported, therefore
+			no swap file will be used when xchacha20 encryption is
+			enabled.
+			Encryption of undo files is not yet supported,
+			therefore no undo file will currently be written.
+			CAREFUL: Files written with this method might have to
+			be read back with the same version of Vim if the
+			binary format changes later.
+			Obsolete, please do no longer use.
+	   xchacha20v2  Same algorithm as with "xchacha20" that correctly
+			stores the key derivation parameters together with the
+			encrypted file.  Should work better in case the
+			parameters in the libsodium library ever change.
+			STILL EXPERIMENTAL: Files written with this method
+			might have to be read back with the same version of
+			Vim if the binary format changes later.
+
+	You should use "blowfish2", also to re-encrypt older files.  The
+	"xchacha20" method provides better encryption, but it does not work
+	with all versions of Vim.
+
+	When reading an encrypted file 'cryptmethod' will be set automatically
+	to the detected method of the file being read.  Thus if you write it
+	without changing 'cryptmethod' the same method will be used.
+	Changing 'cryptmethod' does not mark the file as modified, you have to
+	explicitly write it, you don't get a warning unless there are other
+	modifications.  Also see |:X|.
+
+	When setting the global value to an empty string, it will end up with
+	the value "blowfish2".  When setting the local value to an empty
+	string the buffer will use the global value.
+
+	When a new encryption method is added in a later version of Vim, and
+	the current version does not recognize it, you will get	*E821* .
+	You need to edit this file with the later version of Vim.

+
+			*'cursorbind'* *'crb'* *'nocursorbind'* *'nocrb'*
+'cursorbind' 'crb'	boolean  (default off)
+			local to window
+	When this option is set, as the cursor in the current
+	window moves other cursorbound windows (windows that also have
+	this option set) move their cursors to the corresponding line and
+	column.  This option is useful for viewing the
+	differences between two versions of a file (see 'diff'); in diff mode,
+	inserted and deleted lines (though not characters within a line) are
+	taken into account.
+
+
+			*'cursorcolumn'* *'cuc'* *'nocursorcolumn'* *'nocuc'*
+'cursorcolumn' 'cuc'	boolean	(default off)
+			local to window
+			{not available when compiled without the |+syntax|
+			feature}
+	Highlight the screen column of the cursor with CursorColumn
+	|hl-CursorColumn|.  Useful to align text.  Will make screen redrawing
+	slower.
+	If you only want the highlighting in the current window you can use
+	these autocommands: >
+		au WinLeave * set nocursorline nocursorcolumn
+		au WinEnter * set cursorline cursorcolumn

+'cursorline' 'cul'	boolean	(default off)
+			local to window
+			{not available when compiled without the |+syntax|
+			feature}
+	Highlight the text line of the cursor with CursorLine |hl-CursorLine|.
+	Useful to easily spot the cursor.  Will make screen redrawing slower.
+	When Visual mode is active the highlighting isn't used to make it
+	easier to see the selected text.
+
+
+						*'cursorlineopt'* *'culopt'*
+'cursorlineopt' 'culopt' string (default: "number,line")
+			local to window
+			{not available when compiled without the |+syntax|

+	"screenline"	Highlight only the screen line of the cursor with
+			CursorLine |hl-CursorLine|.
+	"number"	Highlight the line number of the cursor with
+			CursorLineNr |hl-CursorLineNr|.
+
+	Special value:

+
+	"line" and "screenline" cannot be used together.
+
+
+						*'debug'*
+'debug'			string	(default "")
+			global
+	These values can be used:
+	msg	Error messages that would otherwise be omitted will be given
+		anyway.
+	throw	Error messages that would otherwise be omitted will be given
+		anyway and also throw an exception and set |v:errmsg|.
+	beep	A message will be given when otherwise only a beep would be
+		produced.
+	The values can be combined, separated by a comma.
+	"msg" and "throw" are useful for debugging 'foldexpr', 'formatexpr' or
+	'indentexpr'.
+
+						*'define'* *'def'*
+'define' 'def'		string	(default "^\s*#\s*define")
+			global or local to buffer |global-local|
+	Pattern to be used to find a macro definition.  It is a search
+	pattern, just like for the "/" command.  This option is used for the
+	commands like "[i" and "[d" |include-search|.  The 'isident' option is
+	used to recognize the defined name after the match:
+		{match with 'define'}{non-ID chars}{defined name}{non-ID char}
+	See |option-backslash| about inserting backslashes to include a space
+	or backslash.
+	The default value is for C programs.  For C++ this value would be
+	useful, to include const type declarations: >
+		^\(#\s*define\|[a-z]*\s*const\s*[a-z]*\)
+<	You can also use "\ze" just before the name and continue the pattern
+	to check what is following.  E.g. for Javascript, if a function is
+	defined with "func_name = function(args)": >
+		^\s*\ze\i\+\s*=\s*function(
+<	If the function is defined with "func_name : function() {...": >
+	        ^\s*\ze\i\+\s*[:]\s*(*function\s*(
+<	When using the ":set" command, you need to double the backslashes!
+	To avoid that use `:let` with a single quote string: >
+		let &l:define = '^\s*\ze\k\+\s*=\s*function('
+<
+
+			*'delcombine'* *'deco'* *'nodelcombine'* *'nodeco'*
+'delcombine' 'deco'	boolean (default off)
+			global
+	If editing Unicode and this option is set, backspace and Normal mode
+	"x" delete each combining character on its own.  When it is off (the
+	default) the character along with its combining characters are
+	deleted.
+	Note: When 'delcombine' is set "xx" may work differently from "2x"!
+
+	This is useful for Arabic, Hebrew and many other languages where one
+	may have combining characters overtop of base characters, and want
+	to remove only the combining ones.
+	NOTE: This option is reset when 'compatible' is set.
+
+						*'dictionary'* *'dict'*
+'dictionary' 'dict'	string	(default "")
+			global or local to buffer |global-local|
+	List of file names, separated by commas, that are used to lookup words
+	for keyword completion commands |i_CTRL-X_CTRL-K|.  Each file should
+	contain a list of words.  This can be one word per line, or several
+	words per line, separated by non-keyword characters (white space is
+	preferred).  Maximum line length is 510 bytes.
+
+	When this option is empty or an entry "spell" is present, and spell
+	checking is enabled, words in the word lists for the currently active
+	'spelllang' are used. See |spell|.
+
+	To include a comma in a file name precede it with a backslash.  Spaces
+	after a comma are ignored, otherwise spaces are included in the file
+	name.  See |option-backslash| about using backslashes.
+	This has nothing to do with the |Dictionary| variable type.
+	Where to find a list of words?
+	- On FreeBSD, there is the file "/usr/share/dict/words".
+	- In the Simtel archive, look in the "msdos/linguist" directory.
+	- In "miscfiles" of the GNU collection.
+	The use of |:set+=| and |:set-=| is preferred when adding or removing
+	directories from the list.  This avoids problems when a future version
+	uses another default.
+	Backticks cannot be used in this option for security reasons.
+
+							*'diff'* *'nodiff'*
+'diff'			boolean	(default off)
+			local to window
+			{not available when compiled without the |+diff|
+			feature}
+	Join the current window in the group of windows that shows differences
+	between files.  See |vimdiff|.
+
+						*'dex'* *'diffexpr'*
+'diffexpr' 'dex'	string	(default "")
+			global
+			{not available when compiled without the |+diff|
+			feature}
+	Expression which is evaluated to obtain a diff file (either ed-style
+	or unified-style) from two versions of a file.  See |diff-diffexpr|.
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+						*'dip'* *'diffopt'*
+'diffopt' 'dip'		string	(default "internal,filler,closeoff")
+			global
+			{not available when compiled without the |+diff|
+			feature}
+	Option settings for diff mode.  It can consist of the following items.
+	All are optional.  Items must be separated by a comma.
+
+		filler		Show filler lines, to keep the text
+				synchronized with a window that has inserted
+				lines at the same position.  Mostly useful
+				when windows are side-by-side and 'scrollbind'
+				is set.
+
+		context:{n}	Use a context of {n} lines between a change
+				and a fold that contains unchanged lines.
+				When omitted a context of six lines is used.
+				When using zero the context is actually one,
+				since folds require a line in between, also
+				for a deleted line.
+				See |fold-diff|.
+
+		iblank		Ignore changes where lines are all blank.  Adds
+				the "-B" flag to the "diff" command if
+				'diffexpr' is empty.  Check the documentation
+				of the "diff" command for what this does
+				exactly.
+				NOTE: the diff windows will get out of sync,
+				because no differences between blank lines are
+				taken into account.
+
+		icase		Ignore changes in case of text.  "a" and "A"
+				are considered the same.  Adds the "-i" flag
+				to the "diff" command if 'diffexpr' is empty.
+
+		iwhite		Ignore changes in amount of white space.  Adds
+				the "-b" flag to the "diff" command if
+				'diffexpr' is empty.  Check the documentation
+				of the "diff" command for what this does
+				exactly.  It should ignore adding trailing
+				white space, but not leading white space.
+
+		iwhiteall	Ignore all white space changes.  Adds
+				the "-w" flag to the "diff" command if
+				'diffexpr' is empty.  Check the documentation
+				of the "diff" command for what this does
+				exactly.
+
+		iwhiteeol	Ignore white space changes at end of line.
+				Adds the "-Z" flag to the "diff" command if
+				'diffexpr' is empty.  Check the documentation
+				of the "diff" command for what this does
+				exactly.
+
+		horizontal	Start diff mode with horizontal splits (unless
+				explicitly specified otherwise).
+
+		vertical	Start diff mode with vertical splits (unless
+				explicitly specified otherwise).
+
+		closeoff	When a window is closed where 'diff' is set
+				and there is only one window remaining in the
+				same tab page with 'diff' set, execute
+				`:diffoff` in that window.  This undoes a
+				`:diffsplit` command.
+
+		hiddenoff	Do not use diff mode for a buffer when it
+				becomes hidden.
+
+		foldcolumn:{n}	Set the 'foldcolumn' option to {n} when
+				starting diff mode.  Without this 2 is used.
+
+		followwrap	Follow the 'wrap' option and leave as it is.
+
+		internal	Use the internal diff library.  This is
+				ignored when 'diffexpr' is set.  *E960*
+				When running out of memory when writing a
+				buffer this item will be ignored for diffs
+				involving that buffer.  Set the 'verbose'
+				option to see when this happens.
+
+		indent-heuristic
+				Use the indent heuristic for the internal
+				diff library.
+
+                algorithm:{text} Use the specified diff algorithm with the
+				internal diff engine. Currently supported
+				algorithms are:
+				myers      the default algorithm
+				minimal    spend extra time to generate the
+					   smallest possible diff
+				patience   patience diff algorithm
+				histogram  histogram diff algorithm
+
+	Examples: >
+		:set diffopt=internal,filler,context:4
+		:set diffopt=
+		:set diffopt=internal,filler,foldcolumn:3
+		:set diffopt-=internal  " do NOT use the internal diff parser

+				     *'digraph'* *'dg'* *'nodigraph'* *'nodg'*
+'digraph' 'dg'		boolean	(default off)
+			global
+			{not available when compiled without the |+digraphs|
+			feature}
+	Enable the entering of digraphs in Insert mode with {char1} <BS>
+	{char2}.  See |digraphs|.
+	NOTE: This option is reset when 'compatible' is set.
+
+						*'directory'* *'dir'*
+'directory' 'dir'	string	(default for Amiga: ".,t:",
+				 for Win32: ".,$TEMP,c:\tmp,c:\temp"
+				 for Unix: ".,~/tmp,/var/tmp,/tmp")
+			global
+	List of directory names for the swap file, separated with commas.
+	Recommended value:  ".,~/vimswap//" - this will put the swap file next
+	to the edited file if possible, and in your personal swap directory
+	otherwise.  Make sure "~/vimswap//" is only readable for you.
+
+	Possible items:
+	- The swap file will be created in the first directory where this is
+	  possible.
+	- Empty means that no swap file will be used (recovery is
+	  impossible!) and no |E303| error will be given.
+	- A directory "." means to put the swap file in the same directory as
+	  the edited file.  On Unix, a dot is prepended to the file name, so
+	  it doesn't show in a directory listing.  On MS-Windows the "hidden"
+	  attribute is set and a dot prepended if possible.
+	- A directory starting with "./" (or ".\" for MS-Windows) means to put
+	  the swap file relative to where the edited file is.  The leading "."
+	  is replaced with the path name of the edited file.
+	- For Unix and Win32, if a directory ends in two path separators "//",
+	  the swap file name will be built from the complete path to the file
+	  with all path separators replaced by percent '%' signs (including
+	  the colon following the drive letter on Win32). This will ensure
+	  file name uniqueness in the preserve directory.
+	  On Win32, it is also possible to end with "\\".  However, When a
+	  separating comma is following, you must use "//", since "\\" will
+	  include the comma in the file name. Therefore it is recommended to
+	  use '//', instead of '\\'.
+	- Spaces after the comma are ignored, other spaces are considered part
+	  of the directory name.  To have a space at the start of a directory
+	  name, precede it with a backslash.
+	- To include a comma in a directory name precede it with a backslash.
+	- A directory name may end in an ':' or '/'.
+	- Environment variables are expanded |:set_env|.
+	- Careful with '\' characters, type one before a space, type two to
+	  get one in the option (see |option-backslash|), for example: >
+	    :set dir=c:\\tmp,\ dir\\,with\\,commas,\\\ dir\ with\ spaces
+<	- For backwards compatibility with Vim version 3.0 a '>' at the start
+	  of the option is removed.
+	Using "." first in the list is recommended.  This means that editing
+	the same file twice will result in a warning.  Using "/tmp" on Unix is
+	discouraged: When the system crashes you lose the swap file.
+	"/var/tmp" is often not cleared when rebooting, thus is a better
+	choice than "/tmp".  But others on the computer may be able to see the
+	files, and it can contain a lot of files, your swap files get lost in
+	the crowd.  That is why a "tmp" directory in your home directory is
+	tried first.
+	The use of |:set+=| and |:set-=| is preferred when adding or removing
+	directories from the list.  This avoids problems when a future version
+	uses another default.
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+					*'display'* *'dy'*
+'display' 'dy'		string	(default "", set to "truncate" in
+							       |defaults.vim|)
+			global
+	Change the way text is displayed.  This is a comma-separated list of
+	flags:
+	lastline	When included, as much as possible of the last line
+			in a window will be displayed.  "@@@" is put in the
+			last columns of the last screen line to indicate the
+			rest of the line is not displayed.
+	truncate	Like "lastline", but "@@@" is displayed in the first
+			column of the last screen line.  Overrules "lastline".
+	uhex		Show unprintable characters hexadecimal as <xx>
+			instead of using ^C and ~C.
+
+	When neither "lastline" nor "truncate" is included, a last line that
+	doesn't fit is replaced with "@" lines.
+
+	The "@" character can be changed by setting the "lastline" item in
+	'fillchars'.  The character is highlighted with |hl-NonText|.
+
+						*'eadirection'* *'ead'*
+'eadirection' 'ead'	string	(default "both")
+			global
+	Tells when the 'equalalways' option applies:
+		ver	vertically, width of windows is not affected
+		hor	horizontally, height of windows is not affected
+		both	width and height of windows is affected
+
+			   *'ed'* *'edcompatible'* *'noed'* *'noedcompatible'*
+'edcompatible' 'ed'	boolean	(default off)
+			global
+	Makes the 'g' and 'c' flags of the ":substitute" command to be
+	toggled each time the flag is given.  See |complex-change|.  See
+	also 'gdefault' option.
+	Switching this option on may break plugins!
+	This option is not used in |Vim9| script.
+
+					*'emoji'* *'emo'* *'noemoji'* *'noemo'*
+'emoji' 'emo'	boolean (default: on)
+			global
+	When on all Unicode emoji characters are considered to be full width.
+	This excludes "text emoji" characters, which are normally displayed as
+	single width.  Unfortunately there is no good specification for this
+	and it has been determined on trial-and-error basis.  Use the
+	|setcellwidths()| function to change the behavior.
+
+					*'encoding'* *'enc'* *E543*
+'encoding' 'enc'	string (default for MS-Windows: "utf-8",
+				otherwise: value from $LANG or "latin1")
+			global
+	Sets the character encoding used inside Vim.  It applies to text in
+	the buffers, registers, Strings in expressions, text stored in the
+	viminfo file, etc.  It sets the kind of characters which Vim can work
+	with.  See |encoding-names| for the possible values.
+
+	NOTE: Changing this option will not change the encoding of the
+	existing text in Vim.  It may cause non-ASCII text to become invalid.
+	It should normally be kept at its default value, or set when Vim
+	starts up.  See |multibyte|.  To reload the menus see |:menutrans|.
+
+	This option cannot be set from a |modeline|.  It would most likely
+	corrupt the text.
+
+	NOTE: For GTK+ 2 or later, it is highly recommended to set 'encoding'
+	to "utf-8".  Although care has been taken to allow different values of
+	'encoding', "utf-8" is the natural choice for the environment and
+	avoids unnecessary conversion overhead.  "utf-8" has not been made
+	the default to prevent different behavior of the GUI and terminal
+	versions, and to avoid changing the encoding of newly created files
+	without your knowledge (in case 'fileencodings' is empty).
+
+	The character encoding of files can be different from 'encoding'.
+	This is specified with 'fileencoding'.  The conversion is done with
+	iconv() or as specified with 'charconvert'.
+
+	If you need to know whether 'encoding' is a multibyte encoding, you
+	can use: >
+		if has("multi_byte_encoding")
+<
+	Normally 'encoding' will be equal to your current locale.  This will
+	be the default if Vim recognizes your environment settings.  If
+	'encoding' is not set to the current locale, 'termencoding' must be
+	set to convert typed and displayed text.  See |encoding-table|.
+
+	When you set this option, it fires the |EncodingChanged| autocommand
+	event so that you can set up fonts if necessary.
+
+	When the option is set, the value is converted to lowercase.  Thus
+	you can set it with uppercase values too.  Underscores are translated
+	to '-' signs.
+	When the encoding is recognized, it is changed to the standard name.
+	For example "Latin-1" becomes "latin1", "ISO_88592" becomes
+	"iso-8859-2" and "utf8" becomes "utf-8".
+
+	Note: "latin1" is also used when the encoding could not be detected.
+	This only works when editing files in the same encoding!  When the
+	actual character set is not latin1, make sure 'fileencoding' and
+	'fileencodings' are empty.  When conversion is needed, switch to using
+	utf-8.
+
+	When "unicode", "ucs-2" or "ucs-4" is used, Vim internally uses utf-8.
+	You don't notice this while editing, but it does matter for the
+	|viminfo-file|.  And Vim expects the terminal to use utf-8 too.  Thus
+	setting 'encoding' to one of these values instead of utf-8 only has
+	effect for encoding used for files when 'fileencoding' is empty.
+
+	When 'encoding' is set to a Unicode encoding, and 'fileencodings' was
+	not set yet, the default for 'fileencodings' is changed.
+
+			*'endoffile'* *'eof'* *'noendoffile'* *'noeof'*
+'endoffile' 'eof'	boolean	(default off)
+			local to buffer
+	Indicates that a CTRL-Z character was found at the end of the file
+	when reading it.  Normally only happens when 'fileformat' is "dos".
+	When writing a file and this option is off and the 'binary' option
+	is on, or 'fixeol' option is off, no CTRL-Z will be written at the
+	end of the file.
+	See |eol-and-eof| for example settings.
+
+			*'endofline'* *'eol'* *'noendofline'* *'noeol'*
+'endofline' 'eol'	boolean	(default on)
+			local to buffer
+	When writing a file and this option is off and the 'binary' option
+	is on, or 'fixeol' option is off, no <EOL> will be written for the
+	last line in the file.  This option is automatically set or reset when
+	starting to edit a new file, depending on whether file has an <EOL>
+	for the last line in the file.  Normally you don't have to set or
+	reset this option.
+	When 'binary' is off and 'fixeol' is on the value is not used when
+	writing the file.  When 'binary' is on or 'fixeol' is off it is used
+	to remember the presence of a <EOL> for the last line in the file, so
+	that when you write the file the situation from the original file can
+	be kept.  But you can change it if you want to.
+	See |eol-and-eof| for example settings.
+
+			     *'equalalways'* *'ea'* *'noequalalways'* *'noea'*
+'equalalways' 'ea'	boolean	(default on)
+			global
+	When on, all the windows are automatically made the same size after
+	splitting or closing a window.  This also happens the moment the
+	option is switched on.  When off, splitting a window will reduce the
+	size of the current window and leave the other windows the same.  When
+	closing a window the extra lines are given to the window next to it
+	(depending on 'splitbelow' and 'splitright').
+	When mixing vertically and horizontally split windows, a minimal size
+	is computed and some windows may be larger if there is room.  The
+	'eadirection' option tells in which direction the size is affected.
+	Changing the height and width of a window can be avoided by setting
+	'winfixheight' and 'winfixwidth', respectively.
+	If a window size is specified when creating a new window sizes are
+	currently not equalized (it's complicated, but may be implemented in
+	the future).
+
+						*'equalprg'* *'ep'*
+'equalprg' 'ep'		string	(default "")
+			global or local to buffer |global-local|
+	External program to use for "=" command.  When this option is empty
+	the internal formatting functions are used; either 'lisp', 'cindent'
+	or 'indentexpr'.  When Vim was compiled without internal formatting,
+	the "indent" program is used.
+	Environment variables are expanded |:set_env|.  See |option-backslash|
+	about including spaces and backslashes.
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+			*'errorbells'* *'eb'* *'noerrorbells'* *'noeb'*
+'errorbells' 'eb'	boolean	(default off)
+			global
+	Ring the bell (beep or screen flash) for error messages.  This only
+	makes a difference for error messages, the bell will be used always
+	for a lot of errors without a message (e.g., hitting <Esc> in Normal
+	mode).  See 'visualbell' on how to make the bell behave like a beep,
+	screen flash or do nothing. See 'belloff' to finetune when to ring the
+	bell.

+	Name of the errorfile for the QuickFix mode (see |:cf|).
+	When the "-q" command-line argument is used, 'errorfile' is set to the
+	following argument.  See |-q|.
+	NOT used for the ":make" command.  See 'makeef' for that.
+	Environment variables are expanded |:set_env|.
+	See |option-backslash| about including spaces and backslashes.

+'errorformat' 'efm'	string	(default is very long)
+			global or local to buffer |global-local|
+			{not available when compiled without the |+quickfix|

+	Scanf-like description of the format for the lines in the error file
+	(see |errorformat|).
+
+				     *'esckeys'* *'ek'* *'noesckeys'* *'noek'*
+'esckeys' 'ek'		boolean	(Vim default: on, Vi default: off)
+			global
+	Function keys that start with an <Esc> are recognized in Insert
+	mode.  When this option is off, the cursor and function keys cannot be
+	used in Insert mode if they start with an <Esc>.  The advantage of
+	this is that the single <Esc> is recognized immediately, instead of
+	after one second.  Instead of resetting this option, you might want to
+	try changing the values for 'timeoutlen' and 'ttimeoutlen'.  Note that
+	when 'esckeys' is off, you can still map anything, but the cursor keys
+	won't work by default.
+	NOTE: This option is set to the Vi default value when 'compatible' is
+	set and to the Vim default value when 'compatible' is reset.
+	NOTE: when this option is off then the |modifyOtherKeys| functionality
+	is disabled while in Insert mode to avoid ending Insert mode with any
+	key that has a modifier.
+
+						*'eventignore'* *'ei'*
+'eventignore' 'ei'	string	(default "")
+			global
+	A list of autocommand event names, which are to be ignored.
+	When set to "all" or when "all" is one of the items, all autocommand
+	events are ignored, autocommands will not be executed.
+	Otherwise this is a comma-separated list of event names.  Example: >
+	    :set ei=WinEnter,WinLeave
+<
+				 *'expandtab'* *'et'* *'noexpandtab'* *'noet'*
+'expandtab' 'et'	boolean	(default off)
+			local to buffer
+	In Insert mode: Use the appropriate number of spaces to insert a
+	<Tab>.  Spaces are used in indents with the '>' and '<' commands and
+	when 'autoindent' is on.  To insert a real tab when 'expandtab' is
+	on, use CTRL-V<Tab>.  See also |:retab| and |ins-expandtab|.
+	This option is reset when the 'paste' option is set and restored when
+	the 'paste' option is reset.
+	NOTE: This option is reset when 'compatible' is set.
+
+					*'exrc'* *'ex'* *'noexrc'* *'noex'*
+'exrc' 'ex'		boolean (default off)
+			global
+	Enables the reading of .vimrc, .exrc and .gvimrc in the current
+	directory.
+
+	Setting this option is a potential security leak.  E.g., consider
+	unpacking a package or fetching files from github, a .vimrc in there
+	might be a trojan horse.  BETTER NOT SET THIS OPTION!
+	Instead, define an autocommand in your .vimrc to set options for a
+	matching directory.
+
+	If you do switch this option on you should also consider setting the
+	'secure' option (see |initialization|).
+	Also see |.vimrc| and |gui-init|.
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+				*'fileencoding'* *'fenc'* *E213*
+'fileencoding' 'fenc'	string (default: "")
+			local to buffer
+	Sets the character encoding for the file of this buffer.
+
+	When 'fileencoding' is different from 'encoding', conversion will be
+	done when writing the file.  For reading see below.
+	When 'fileencoding' is empty, the same value as 'encoding' will be
+	used (no conversion when reading or writing a file).
+	No error will be given when the value is set, only when it is used,
+	only when writing a file.
+	Conversion will also be done when 'encoding' and 'fileencoding' are
+	both a Unicode encoding and 'fileencoding' is not utf-8.  That's
+	because internally Unicode is always stored as utf-8.
+		WARNING: Conversion can cause loss of information!  When
+		'encoding' is "utf-8" or another Unicode encoding, conversion
+		is most likely done in a way that the reverse conversion
+		results in the same text.  When 'encoding' is not "utf-8" some
+		characters may be lost!
+
+	See 'encoding' for the possible values.  Additionally, values may be
+	specified that can be handled by the converter, see
+	|mbyte-conversion|.
+
+	When reading a file 'fileencoding' will be set from 'fileencodings'.
+	To read a file in a certain encoding it won't work by setting
+	'fileencoding', use the |++enc| argument.  One exception: when
+	'fileencodings' is empty the value of 'fileencoding' is used.
+	For a new file the global value of 'fileencoding' is used.
+
+	Prepending "8bit-" and "2byte-" has no meaning here, they are ignored.
+	When the option is set, the value is converted to lowercase.  Thus
+	you can set it with uppercase values too.  '_' characters are
+	replaced with '-'.  If a name is recognized from the list for
+	'encoding', it is replaced by the standard name.  For example
+	"ISO8859-2" becomes "iso-8859-2".
+
+	When this option is set, after starting to edit a file, the 'modified'
+	option is set, because the file would be different when written.
+
+	Keep in mind that changing 'fenc' from a modeline happens
+	AFTER the text has been read, thus it applies to when the file will be
+	written.  If you do set 'fenc' in a modeline, you might want to set
+	'nomodified' to avoid not being able to ":q".
+
+	This option can not be changed when 'modifiable' is off.
+
+							*'fe'*
+	NOTE: Before version 6.0 this option specified the encoding for the
+	whole of Vim, this was a mistake.  Now use 'encoding' instead.  The
+	old short name was 'fe', which is no longer used.
+
+					*'fileencodings'* *'fencs'*
+'fileencodings' 'fencs'	string (default: "ucs-bom",
+				    "ucs-bom,utf-8,default,latin1" when
+				    'encoding' is set to a Unicode value)
+			global
+	This is a list of character encodings considered when starting to edit
+	an existing file.  When a file is read, Vim tries to use the first
+	mentioned character encoding.  If an error is detected, the next one
+	in the list is tried.  When an encoding is found that works,
+	'fileencoding' is set to it.  If all fail, 'fileencoding' is set to
+	an empty string, which means the value of 'encoding' is used.
+		WARNING: Conversion can cause loss of information!  When
+		'encoding' is "utf-8" (or one of the other Unicode variants)
+		conversion is most likely done in a way that the reverse
+		conversion results in the same text.  When 'encoding' is not
+		"utf-8" some non-ASCII characters may be lost!  You can use
+		the |++bad| argument to specify what is done with characters
+		that can't be converted.
+	For an empty file or a file with only ASCII characters most encodings
+	will work and the first entry of 'fileencodings' will be used (except
+	"ucs-bom", which requires the BOM to be present).  If you prefer
+	another encoding use an BufReadPost autocommand event to test if your
+	preferred encoding is to be used.  Example: >
+		au BufReadPost * if search('\S', 'w') == 0 |
+			\ set fenc=iso-2022-jp | endif
+<	This sets 'fileencoding' to "iso-2022-jp" if the file does not contain
+	non-blank characters.
+	When the |++enc| argument is used then the value of 'fileencodings' is
+	not used.
+	Note that 'fileencodings' is not used for a new file, the global value
+	of 'fileencoding' is used instead.  You can set it with: >
+		:setglobal fenc=iso-8859-2
+<	This means that a non-existing file may get a different encoding than
+	an empty file.
+	The special value "ucs-bom" can be used to check for a Unicode BOM
+	(Byte Order Mark) at the start of the file.  It must not be preceded
+	by "utf-8" or another Unicode encoding for this to work properly.
+	An entry for an 8-bit encoding (e.g., "latin1") should be the last,
+	because Vim cannot detect an error, thus the encoding is always
+	accepted.
+	The special value "default" can be used for the encoding from the
+	environment.  On MS-Windows this is the system encoding.  Otherwise
+	this is the default value for 'encoding'.  It is useful when
+	'encoding' is set to "utf-8" and your environment uses a non-latin1
+	encoding, such as Russian.
+	When 'encoding' is "utf-8" and a file contains an illegal byte
+	sequence it won't be recognized as UTF-8.  You can use the |8g8|
+	command to find the illegal byte sequence.
+	WRONG VALUES:			WHAT'S WRONG:
+		latin1,utf-8		"latin1" will always be used
+		utf-8,ucs-bom,latin1	BOM won't be recognized in an utf-8
+					file
+		cp1250,latin1		"cp1250" will always be used
+	If 'fileencodings' is empty, 'fileencoding' is not modified.
+	See 'fileencoding' for the possible values.
+	Setting this option does not have an effect until the next time a file
+	is read.
+
+					*'fileformat'* *'ff'*
+'fileformat' 'ff'	string (MS-Windows default: "dos",
+				Unix, macOS default: "unix")
+			local to buffer
+	This gives the <EOL> of the current buffer, which is used for
+	reading/writing the buffer from/to a file:
+	    dos	    <CR><NL>
+	    unix    <NL>
+	    mac	    <CR>
+	When "dos" is used, CTRL-Z at the end of a file is ignored.
+	See |file-formats| and |file-read|.
+	For the character encoding of the file see 'fileencoding'.
+	When 'binary' is set, the value of 'fileformat' is ignored, file I/O
+	works like it was set to "unix".
+	This option is set automatically when starting to edit a file and
+	'fileformats' is not empty and 'binary' is off.
+	When this option is set, after starting to edit a file, the 'modified'
+	option is set, because the file would be different when written.
+	This option can not be changed when 'modifiable' is off.
+	For backwards compatibility: When this option is set to "dos",
+	'textmode' is set, otherwise 'textmode' is reset.
+
+					*'fileformats'* *'ffs'*
+'fileformats' 'ffs'	string (default:
+				Vim+Vi	MS-Windows: "dos,unix",
+				Vim	Unix, macOS: "unix,dos",
+				Vi	Cygwin: "unix,dos",
+				Vi	others: "")
+			global
+	This gives the end-of-line (<EOL>) formats that will be tried when
+	starting to edit a new buffer and when reading a file into an existing
+	buffer:
+	- When empty, the format defined with 'fileformat' will be used
+	  always.  It is not set automatically.
+	- When set to one name, that format will be used whenever a new buffer
+	  is opened.  'fileformat' is set accordingly for that buffer.  The
+	  'fileformats' name will be used when a file is read into an existing
+	  buffer, no matter what 'fileformat' for that buffer is set to.
+	- When more than one name is present, separated by commas, automatic
+	  <EOL> detection will be done when reading a file.  When starting to
+	  edit a file, a check is done for the <EOL>:
+	  1. If all lines end in <CR><NL>, and 'fileformats' includes "dos",
+	     'fileformat' is set to "dos".
+	  2. If a <NL> is found and 'fileformats' includes "unix", 'fileformat'
+	     is set to "unix".  Note that when a <NL> is found without a
+	     preceding <CR>, "unix" is preferred over "dos".
+	  3. If 'fileformat' has not yet been set, and if a <CR> is found, and
+	     if 'fileformats' includes "mac", 'fileformat' is set to "mac".
+	     This means that "mac" is only chosen when:
+	      "unix" is not present or no <NL> is found in the file, and
+	      "dos" is not present or no <CR><NL> is found in the file.
+	     Except: if "unix" was chosen, but there is a <CR> before
+	     the first <NL>, and there appear to be more <CR>s than <NL>s in
+	     the first few lines, "mac" is used.
+	  4. If 'fileformat' is still not set, the first name from
+	     'fileformats' is used.
+	  When reading a file into an existing buffer, the same is done, but
+	  this happens like 'fileformat' has been set appropriately for that
+	  file only, the option is not changed.
+	When 'binary' is set, the value of 'fileformats' is not used.
+
+	When Vim starts up with an empty buffer the first item is used.  You
+	can overrule this by setting 'fileformat' in your .vimrc.
+
+	For systems with a Dos-like <EOL> (<CR><NL>), when reading files that
+	are ":source"ed and for vimrc files, automatic <EOL> detection may be
+	done:
+	- When 'fileformats' is empty, there is no automatic detection.  Dos
+	  format will be used.
+	- When 'fileformats' is set to one or more names, automatic detection
+	  is done.  This is based on the first <NL> in the file: If there is a
+	  <CR> in front of it, Dos format is used, otherwise Unix format is
+	  used.
+	Also see |file-formats|.
+	For backwards compatibility: When this option is set to an empty
+	string or one format (no comma is included), 'textauto' is reset,
+	otherwise 'textauto' is set.
+	NOTE: This option is set to the Vi default value when 'compatible' is
+	set and to the Vim default value when 'compatible' is reset.
+
+		*'fileignorecase'* *'fic'* *'nofileignorecase'* *'nofic'*
+'fileignorecase' 'fic'	boolean	(default on for systems where case in file
+				 names is normally ignored)
+			global
+	When set case is ignored when using file names and directories.
+	See 'wildignorecase' for only ignoring case when doing completion.
+
+					*'filetype'* *'ft'*
+'filetype' 'ft'		string (default: "")
+			local to buffer
+	When this option is set, the FileType autocommand event is triggered.
+	All autocommands that match with the value of this option will be
+	executed.  Thus the value of 'filetype' is used in place of the file
+	name.
+	Otherwise this option does not always reflect the current file type.
+	This option is normally set when the file type is detected.  To enable
+	this use the ":filetype on" command. |:filetype|
+	Setting this option to a different value is most useful in a modeline,
+	for a file for which the file type is not automatically recognized.
+	Example, for in an IDL file:
+		/* vim: set filetype=idl : */ ~
+	|FileType| |filetypes|
+	When a dot appears in the value then this separates two filetype
+	names.  Example:
+		/* vim: set filetype=c.doxygen : */ ~
+	This will use the "c" filetype first, then the "doxygen" filetype.
+	This works both for filetype plugins and for syntax files.  More than
+	one dot may appear.
+	This option is not copied to another buffer, independent of the 's' or
+	'S' flag in 'cpoptions'.
+	Only normal file name characters can be used, "/\*?[|<>" are illegal.
+
+						*'fillchars'* *'fcs'*
+'fillchars' 'fcs'	string	(default "vert:|,fold:-,eob:~")
+			global or local to window |global-local|
+			{not available when compiled without the |+folding|
+			feature}
+	Characters to fill the statuslines, vertical separators and special
+	lines in the window.
+	It is a comma-separated list of items.  Each item has a name, a colon
+	and the value of that item:
+
+	  item name	default		Used for ~
+	  stl		' ' or '^'	statusline of the current window
+	  stlnc		' ' or '='	statusline of the non-current windows
+	  vert		'|'		vertical separators |:vsplit|
+	  fold		'-'		filling 'foldtext'
+	  foldopen	'-'		mark the beginning of a fold
+	  foldclose	'+'		show a closed fold
+	  foldsep	'|'		open fold middle character
+	  diff		'-'		deleted lines of the 'diff' option
+	  eob		'~'		empty lines below the end of a buffer
+	  lastline	'@'		'display' contains lastline/truncate
+
+	Any one that is omitted will fall back to the default.  For "stl" and
+	"stlnc" the space will be used when there is highlighting, '^' or '='
+	otherwise.
+
+	Example: >
+	    :set fillchars=stl:^,stlnc:=,vert:\|,fold:-,diff:-
+<	This is similar to the default, except that these characters will also
+	be used when there is highlighting.
+
+	For the "stl", "stlnc", "foldopen", "foldclose" and "foldsep" items
+	single-byte and multibyte characters are supported.  But double-width
+	characters are not supported.
+
+	The highlighting used for these items:
+	  item name	highlight group ~
+	  stl		StatusLine		|hl-StatusLine|
+	  stlnc		StatusLineNC		|hl-StatusLineNC|
+	  vert		VertSplit		|hl-VertSplit|
+	  fold		Folded			|hl-Folded|
+	  diff		DiffDelete		|hl-DiffDelete|

+
+		*'fixendofline'* *'fixeol'* *'nofixendofline'* *'nofixeol'*
+'fixendofline' 'fixeol'	boolean	(default on)
+			local to buffer
+	When writing a file and this option is on, <EOL> at the end of file
+	will be restored if missing.  Turn this option off if you want to
+	preserve the situation from the original file.
+	When the 'binary' option is set the value of this option doesn't
+	matter.
+	See the 'endofline' option.

+
+						*'foldclose'* *'fcl'*
+'foldclose' 'fcl'	string (default "")
+			global
+			{not available when compiled without the |+folding|

+
+						*'foldcolumn'* *'fdc'*
+'foldcolumn' 'fdc'	number (default 0)
+			local to window
+			{not available when compiled without the |+folding|

+'foldenable' 'fen'	boolean (default on)
+			local to window

+	When off, all folds are open.  This option can be used to quickly
+	switch between showing all text unfolded and viewing the text with
+	folds (including manually opened or closed folds).  It can be toggled
+	with the |zi| command.  The 'foldcolumn' will remain blank when
+	'foldenable' is off.

+	for each line to obtain its fold level.  The context is set to the
+	script where 'foldexpr' was set, script-local items can be accessed.
+	See |fold-expr| for the usage.
+
+	The expression will be evaluated in the |sandbox| if set from a
+	modeline, see |sandbox-option|.
+	This option can't be set from a |modeline| when the 'diff' option is
+	on or the 'modelineexpr' option is off.
+
+	It is not allowed to change text or jump to another window while
+	evaluating 'foldexpr' |textlock|.
+
+						*'foldignore'* *'fdi'*
+'foldignore' 'fdi'	string (default: "#")
+			local to window
+			{not available when compiled without the |+folding|
+			feature}
+	Used only when 'foldmethod' is "indent".  Lines starting with
+	characters in 'foldignore' will get their fold level from surrounding
+	lines.  White space is skipped before checking for this character.
+	The default "#" works well for C programs.  See |fold-indent|.
+
+						*'foldlevel'* *'fdl'*
+'foldlevel' 'fdl'	number (default: 0)
+			local to window
+			{not available when compiled without the |+folding|
+			feature}
+	Sets the fold level: Folds with a higher level will be closed.
+	Setting this option to zero will close all folds.  Higher numbers will
+	close fewer folds.
+	This option is set by commands like |zm|, |zM| and |zR|.
+	See |fold-foldlevel|.
+
+						*'foldlevelstart'* *'fdls'*
+'foldlevelstart' 'fdls'	number (default: -1)
+			global
+			{not available when compiled without the |+folding|
+			feature}
+	Sets 'foldlevel' when starting to edit another buffer in a window.
+	Useful to always start editing with all folds closed (value zero),
+	some folds closed (one) or no folds closed (99).
+	This is done before reading any modeline, thus a setting in a modeline
+	overrules this option.  Starting to edit a file for |diff-mode| also
+	ignores this option and closes all folds.
+	It is also done before BufReadPre autocommands, to allow an autocmd to
+	overrule the 'foldlevel' value for specific files.
+	When the value is negative, it is not used.
+
+						*'foldmarker'* *'fmr'* *E536*
+'foldmarker' 'fmr'	string (default: "{{{,}}}")
+			local to window
+			{not available when compiled without the |+folding|
+			feature}
+	The start and end marker used when 'foldmethod' is "marker".  There
+	must be one comma, which separates the start and end marker.  The
+	marker is a literal string (a regular expression would be too slow).
+	See |fold-marker|.
+
+						*'foldmethod'* *'fdm'*
+'foldmethod' 'fdm'	string (default: "manual")
+			local to window
+			{not available when compiled without the |+folding|
+			feature}
+	The kind of folding used for the current window.  Possible values:
+	|fold-manual|	manual	    Folds are created manually.
+	|fold-indent|	indent	    Lines with equal indent form a fold.
+	|fold-expr|	expr	    'foldexpr' gives the fold level of a line.
+	|fold-marker|	marker	    Markers are used to specify folds.
+	|fold-syntax|	syntax	    Syntax highlighting items specify folds.
+	|fold-diff|	diff	    Fold text that is not changed.
+
+						*'foldminlines'* *'fml'*
+'foldminlines' 'fml'	number (default: 1)
+			local to window
+			{not available when compiled without the |+folding|
+			feature}
+	Sets the number of screen lines above which a fold can be displayed
+	closed.  Also for manually closed folds.  With the default value of
+	one a fold can only be closed if it takes up two or more screen lines.
+	Set to zero to be able to close folds of just one screen line.
+	Note that this only has an effect on what is displayed.  After using
+	"zc" to close a fold, which is displayed open because it's smaller
+	than 'foldminlines', a following "zc" may close a containing fold.
+
+						*'foldnestmax'* *'fdn'*
+'foldnestmax' 'fdn'	number (default: 20)
+			local to window
+			{not available when compiled without the |+folding|
+			feature}
+	Sets the maximum nesting of folds for the "indent" and "syntax"
+	methods.  This avoids that too many folds will be created.  Using more
+	than 20 doesn't work, because the internal limit is 20.
+
+						*'foldopen'* *'fdo'*
+'foldopen' 'fdo'	string (default: "block,hor,mark,percent,quickfix,
+							     search,tag,undo")
+			global
+			{not available when compiled without the |+folding|
+			feature}
+	Specifies for which type of commands folds will be opened, if the
+	command moves the cursor into a closed fold.  It is a comma-separated
+	list of items.
+	NOTE: When the command is part of a mapping this option is not used.
+	Add the |zv| command to the mapping to get the same effect.
+	(rationale: the mapping may want to control opening folds itself)
+
+		item		commands ~
+		all		any
+		block		"(", "{", "[[", "[{", etc.
+		hor		horizontal movements: "l", "w", "fx", etc.
+		insert		any command in Insert mode
+		jump		far jumps: "G", "gg", etc.
+		mark		jumping to a mark: "'m", CTRL-O, etc.
+		percent		"%"
+		quickfix	":cn", ":crew", ":make", etc.
+		search		search for a pattern: "/", "n", "*", "gd", etc.
+				(not for a search pattern in a ":" command)
+				Also for |[s| and |]s|.
+		tag		jumping to a tag: ":ta", CTRL-T, etc.
+		undo		undo or redo: "u" and CTRL-R
+	When a movement command is used for an operator (e.g., "dl" or "y%")
+	this option is not used.  This means the operator will include the
+	whole closed fold.
+	Note that vertical movements are not here, because it would make it
+	very difficult to move onto a closed fold.
+	In insert mode the folds containing the cursor will always be open
+	when text is inserted.
+	To close folds you can re-apply 'foldlevel' with the |zx| command or
+	set the 'foldclose' option to "all".
+
+						*'foldtext'* *'fdt'*
+'foldtext' 'fdt'	string (default: "foldtext()")
+			local to window
+			{not available when compiled without the |+folding|
+			feature}
+	An expression which is used to specify the text displayed for a closed
+	fold.  The context is set to the script where 'foldexpr' was set,
+	script-local items can be accessed.  See |fold-foldtext| for the
+	usage.
+
+	The expression will be evaluated in the |sandbox| if set from a
+	modeline, see |sandbox-option|.
+	This option cannot be set in a modeline when 'modelineexpr' is off.
+
+	It is not allowed to change text or jump to another window while
+	evaluating 'foldtext' |textlock|.
+
+						*'formatexpr'* *'fex'*
+'formatexpr' 'fex'	string (default "")
+			local to buffer
+			{not available when compiled without the |+eval|
+			feature}
+	Expression which is evaluated to format a range of lines for the |gq|
+	operator or automatic formatting (see 'formatoptions').  When this
+	option is empty 'formatprg' is used.
+
+	The |v:lnum|  variable holds the first line to be formatted.
+	The |v:count| variable holds the number of lines to be formatted.
+	The |v:char|  variable holds the character that is going to be
+		      inserted if the expression is being evaluated due to
+		      automatic formatting.  This can be empty.  Don't insert
+		      it yet!
+
+	Example: >
+		:set formatexpr=mylang#Format()
+<	This will invoke the mylang#Format() function in the
+	autoload/mylang.vim file in 'runtimepath'. |autoload|
+
+	The advantage of using a function call without arguments is that it is
+	faster, see |expr-option-function|.
+
+	The expression is also evaluated when 'textwidth' is set and adding
+	text beyond that limit.  This happens under the same conditions as
+	when internal formatting is used.  Make sure the cursor is kept in the
+	same spot relative to the text then!  The |mode()| function will
+	return "i" or "R" in this situation.
+
+	When the expression evaluates to non-zero Vim will fall back to using
+	the internal format mechanism.
+
+	If the expression starts with s: or |<SID>|, then it is replaced with
+	the script ID (|local-function|). Example: >
+		set formatexpr=s:MyFormatExpr()
+		set formatexpr=<SID>SomeFormatExpr()
+<	Otherwise, the expression is evaluated in the context of the script
+	where the option was set, thus script-local items are available.
+
+	The expression will be evaluated in the |sandbox| when set from a
+	modeline, see |sandbox-option|.  That stops the option from working,
+	since changing the buffer text is not allowed.
+	This option cannot be set in a modeline when 'modelineexpr' is off.
+	NOTE: This option is set to "" when 'compatible' is set.
+
+					*'formatlistpat'* *'flp'*
+'formatlistpat' 'flp'	string (default: "^\s*\d\+[\]:.)}\t ]\s*")
+			local to buffer
+	A pattern that is used to recognize a list header.  This is used for
+	the "n" flag in 'formatoptions'.
+	The pattern must match exactly the text that will be the indent for
+	the line below it.  You can use |/\ze| to mark the end of the match
+	while still checking more characters.  There must be a character
+	following the pattern, when it matches the whole line it is handled
+	like there is no match.
+	The default recognizes a number, followed by an optional punctuation
+	character and white space.
+
+					*'formatoptions'* *'fo'*
+'formatoptions' 'fo'	string (Vim default: "tcq", Vi default: "vt")
+			local to buffer
+	This is a sequence of letters which describes how automatic
+	formatting is to be done.  See |fo-table|.  When the 'paste' option is
+	on, no formatting is done (like 'formatoptions' is empty).  Commas can
+	be inserted for readability.
+	To avoid problems with flags that are added in the future, use the
+	"+=" and "-=" feature of ":set" |add-option-flags|.
+	NOTE: This option is set to the Vi default value when 'compatible' is
+	set and to the Vim default value when 'compatible' is reset.
+
+						*'formatprg'* *'fp'*
+'formatprg' 'fp'	string (default "")
+			global or local to buffer |global-local|
+	The name of an external program that will be used to format the lines
+	selected with the |gq| operator.  The program must take the input on
+	stdin and produce the output on stdout.  The Unix program "fmt" is
+	such a program.
+	If the 'formatexpr' option is not empty it will be used instead.
+	Otherwise, if 'formatprg' option is an empty string, the internal
+	format function will be used |C-indenting|.
+	Environment variables are expanded |:set_env|.  See |option-backslash|
+	about including spaces and backslashes.
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+					*'fsync'* *'fs'* *'nofsync'* *'nofs'*
+'fsync' 'fs'		boolean	(default on)
+			global
+	When on, the library function fsync() will be called after writing a
+	file.  This will flush a file to disk, ensuring that it is safely
+	written even on filesystems which do metadata-only journaling.  This
+	will force the harddrive to spin up on Linux systems running in laptop
+	mode, so it may be undesirable in some situations.  Be warned that
+	turning this off increases the chances of data loss after a crash.  On
+	systems without an fsync() implementation, this variable is always
+	off.
+	Also see 'swapsync' for controlling fsync() on swap files.
+	'fsync' also applies to |writefile()| (unless a flag is used to
+	overrule it) and when writing undo files (see |undo-persistence|).
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+				   *'gdefault'* *'gd'* *'nogdefault'* *'nogd'*
+'gdefault' 'gd'		boolean	(default off)
+			global
+	When on, the ":substitute" flag 'g' is default on.  This means that
+	all matches in a line are substituted instead of one.  When a 'g' flag
+	is given to a ":substitute" command, this will toggle the substitution
+	of all or one match.  See |complex-change|.
+
+		command		'gdefault' on	'gdefault' off	~
+		:s///		  subst. all	  subst. one
+		:s///g		  subst. one	  subst. all
+		:s///gg		  subst. all	  subst. one
+
+	NOTE: This option is reset when 'compatible' is set.
+	DEPRECATED: Setting this option may break plugins that are not aware
+	of this option.  Also, many users get confused that adding the /g flag
+	has the opposite effect of that it normally does.
+	This option is not used in |Vim9| script.
+
+						*'grepformat'* *'gfm'*
+'grepformat' 'gfm'	string	(default "%f:%l:%m,%f:%l%m,%f  %l%m")
+			global
+	Format to recognize for the ":grep" command output.
+	This is a scanf-like string that uses the same format as the
+	'errorformat' option: see |errorformat|.
+
+						*'grepprg'* *'gp'*
+'grepprg' 'gp'		string	(default "grep -n ",
+					Unix: "grep -n $* /dev/null",
+					Win32: "findstr /n" or "grep -n",
+						      VMS: "SEARCH/NUMBERS ")
+			global or local to buffer |global-local|
+	Program to use for the |:grep| command.  This option may contain '%'
+	and '#' characters, which are expanded like when used in a command-
+	line.  The placeholder "$*" is allowed to specify where the arguments
+	will be included.  Environment variables are expanded |:set_env|.  See
+	|option-backslash| about including spaces and backslashes.
+	When your "grep" accepts the "-H" argument, use this to make ":grep"
+	also work well with a single file: >
+		:set grepprg=grep\ -nH
+<	Special value: When 'grepprg' is set to "internal" the |:grep| command
+	works like |:vimgrep|, |:lgrep| like |:lvimgrep|, |:grepadd| like
+	|:vimgrepadd| and |:lgrepadd| like |:lvimgrepadd|.
+	See also the section |:make_makeprg|, since most of the comments there
+	apply equally to 'grepprg'.
+	For Win32, the default is "findstr /n" if "findstr.exe" can be found,
+	otherwise it's "grep -n".
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+			*'guicursor'* *'gcr'* *E545* *E546* *E548* *E549*
+'guicursor' 'gcr'	string	(default "n-v-c:block-Cursor/lCursor,
+					ve:ver35-Cursor,
+					o:hor50-Cursor,
+					i-ci:ver25-Cursor/lCursor,
+					r-cr:hor20-Cursor/lCursor,
+					sm:block-Cursor
+					-blinkwait175-blinkoff150-blinkon175",
+				for Win32 console:
+					"n-v-c:block,o:hor50,i-ci:hor15,
+					r-cr:hor30,sm:block")
+			global
+			{only available when compiled with GUI enabled, and
+			for Win32 console}
+	This option tells Vim what the cursor should look like in different
+	modes.  It fully works in the GUI.  In a Win32 console, only the
+	height of the cursor can be changed.  This can be done by specifying a
+	block cursor, or a percentage for a vertical or horizontal cursor.
+	For a console the 't_SI', 't_SR', and 't_EI' escape sequences are
+	used.
+
+	The option is a comma-separated list of parts.  Each part consist of a
+	mode-list and an argument-list:
+		mode-list:argument-list,mode-list:argument-list,..
+	The mode-list is a dash separated list of these modes:
+		n	Normal mode
+		v	Visual mode
+		ve	Visual mode with 'selection' "exclusive" (same as 'v',
+			if not specified)
+		o	Operator-pending mode
+		i	Insert mode
+		r	Replace mode
+		c	Command-line Normal (append) mode
+		ci	Command-line Insert mode
+		cr	Command-line Replace mode
+		sm	showmatch in Insert mode
+		a	all modes
+	The argument-list is a dash separated list of these arguments:
+		hor{N}	horizontal bar, {N} percent of the character height
+		ver{N}	vertical bar, {N} percent of the character width
+		block	block cursor, fills the whole character
+			[only one of the above three should be present]
+		blinkwait{N}				*cursor-blinking*
+		blinkon{N}
+		blinkoff{N}
+			blink times for cursor: blinkwait is the delay before
+			the cursor starts blinking, blinkon is the time that
+			the cursor is shown and blinkoff is the time that the
+			cursor is not shown.  The times are in msec.  When one
+			of the numbers is zero, there is no blinking.  The
+			default is: "blinkwait700-blinkon400-blinkoff250".
+			These numbers are used for a missing entry.  This
+			means that blinking is enabled by default.  To switch
+			blinking off you can use "blinkon0".  The cursor only
+			blinks when Vim is waiting for input, not while
+			executing a command.
+			To make the cursor blink in an xterm, see
+			|xterm-blink|.
+		{group-name}
+			a highlight group name, that sets the color and font
+			for the cursor
+		{group-name}/{group-name}
+			Two highlight group names, the first is used when
+			no language mappings are used, the other when they
+			are. |language-mapping|
+
+	Examples of parts:
+	   n-c-v:block-nCursor	in Normal, Command-line and Visual mode, use a
+				block cursor with colors from the "nCursor"
+				highlight group
+	   i-ci:ver30-iCursor-blinkwait300-blinkon200-blinkoff150
+				In Insert and Command-line Insert mode, use a
+				30% vertical bar cursor with colors from the
+				"iCursor" highlight group.  Blink a bit
+				faster.
+
+	The 'a' mode is different.  It will set the given argument-list for
+	all modes.  It does not reset anything to defaults.  This can be used
+	to do a common setting for all modes.  For example, to switch off
+	blinking: "a:blinkon0"
+
+	Examples of cursor highlighting: >
+	    :highlight Cursor gui=reverse guifg=NONE guibg=NONE
+	    :highlight Cursor gui=NONE guifg=bg guibg=fg
+<
+					*'guifont'* *'gfn'*
+						   *E235* *E596*
+'guifont' 'gfn'		string	(default "")
+			global
+			{only available when compiled with GUI enabled}
+	This is a list of fonts which will be used for the GUI version of Vim.
+	In its simplest form the value is just one font name.
+	See |gui-font| for the details.
+
+					*'guifontset'* *'gfs'*
+					*E250* *E252* *E234* *E597* *E598*
+'guifontset' 'gfs'	string	(default "")
+			global
+			{only available when compiled with GUI enabled and
+			with the |+xfontset| feature}
+			{not available in the GTK+ GUI}
+	When not empty, specifies two (or more) fonts to be used.  The first
+	one for normal English, the second one for your special language.  See
+	|xfontset|.
+
+				*'guifontwide'* *'gfw'* *E231* *E533* *E534*
+'guifontwide' 'gfw'	string	(default "")
+			global
+			{only available when compiled with GUI enabled}
+	When not empty, specifies a comma-separated list of fonts to be used
+	for double-width characters.  The first font that can be loaded is
+	used.  See |gui-fontwide|.
+
+						*'guiheadroom'* *'ghr'*
+'guiheadroom' 'ghr'	number	(default 50)
+			global
+			{only for GTK and X11 GUI}
+	The number of pixels subtracted from the screen height when fitting
+	the GUI window on the screen.  Set this before the GUI is started,
+	e.g., in your |gvimrc| file.  When zero, the whole screen height will
+	be used by the window.  When positive, the specified number of pixel
+	lines will be left for window decorations and other items on the
+	screen.  Set it to a negative value to allow windows taller than the
+	screen.
+
+						*'guiligatures'* *'gli'* *E1243*
+'guiligatures' 'gli'	string	(default "")
+			global
+			{only for GTK GUI}
+	List of ASCII characters that, when combined together, can create more
+	complex shapes. Each character must be a printable ASCII character
+	with a value in the 32-127 range.
+	Example: >
+		:set guiligatures=!\"#$%&()*+-./:<=>?@[]^_{\|~
+<	Changing this option updates screen output immediately. Set it to an
+	empty string to disable ligatures.
+
+						*'guioptions'* *'go'*
+'guioptions' 'go'	string	(default "egmrLtT"   (MS-Windows,
+					   "t" is removed in |defaults.vim|),
+					 "aegimrLtT" (GTK and Motif),
+					 )
+			global
+			{only available when compiled with GUI enabled}
+	This option only has an effect in the GUI version of Vim.  It is a
+	sequence of letters which describes what components and options of the
+	GUI should be used.
+	To avoid problems with flags that are added in the future, use the
+	"+=" and "-=" feature of ":set" |add-option-flags|.
+
+	Valid characters are as follows:
+								*'go-!'*
+	  '!'	External commands are executed in a terminal window.  Without
+		this flag the MS-Windows GUI will open a console window to
+		execute the command.  The Unix GUI will simulate a dumb
+		terminal to list the command output.
+		The terminal window will be positioned at the bottom, and grow
+		upwards as needed.
+								*'go-a'*
+	  'a'	Autoselect:  If present, then whenever VISUAL mode is started,
+		or the Visual area extended, Vim tries to become the owner of
+		the windowing system's global selection.  This means that the
+		Visually highlighted text is available for pasting into other
+		applications as well as into Vim itself.  When the Visual mode
+		ends, possibly due to an operation on the text, or when an
+		application wants to paste the selection, the highlighted text
+		is automatically yanked into the "* selection register.
+		Thus the selection is still available for pasting into other
+		applications after the VISUAL mode has ended.
+		    If not present, then Vim won't become the owner of the
+		windowing system's global selection unless explicitly told to
+		by a yank or delete operation for the "* register.
+		The same applies to the modeless selection.
+								*'go-P'*
+	  'P'	Like autoselect but using the "+ register instead of the "*
+		register.
+								*'go-A'*
+	  'A'	Autoselect for the modeless selection.  Like 'a', but only
+		applies to the modeless selection.
+
+		    'guioptions'   autoselect Visual  autoselect modeless ~
+			 ""		 -			 -
+			 "a"		yes			yes
+			 "A"		 -			yes
+			 "aA"		yes			yes
+
+		When using a terminal see the 'clipboard' option.
+
+								*'go-c'*
+	  'c'	Use console dialogs instead of popup dialogs for simple
+		choices.
+								*'go-d'*
+	  'd'	Use dark theme variant if available. Currently only works for
+		GTK+ GUI.
+								*'go-e'*
+	  'e'	Add tab pages when indicated with 'showtabline'.
+		'guitablabel' can be used to change the text in the labels.
+		When 'e' is missing a non-GUI tab pages line may be used.
+		The GUI tabs are only supported on some systems, currently
+		GTK, Motif, Mac OS/X, Haiku, and MS-Windows.
+								*'go-f'*
+	  'f'	Foreground: Don't use fork() to detach the GUI from the shell
+		where it was started.  Use this for programs that wait for the
+		editor to finish (e.g., an e-mail program).  Alternatively you
+		can use "gvim -f" or ":gui -f" to start the GUI in the
+		foreground.  |gui-fork|
+		Note: Set this option in the vimrc file.  The forking may have
+		happened already when the |gvimrc| file is read.
+								*'go-i'*
+	  'i'	Use a Vim icon.  For GTK with KDE it is used in the left-upper
+		corner of the window.  It's black&white on non-GTK, because of
+		limitations of X11.  For a color icon, see |X11-icon|.
+								*'go-m'*
+	  'm'	Menu bar is present.
+								*'go-M'*
+	  'M'	The system menu "$VIMRUNTIME/menu.vim" is not sourced.  Note
+		that this flag must be added in the .vimrc file, before
+		switching on syntax or filetype recognition (when the |gvimrc|
+		file is sourced the system menu has already been loaded; the
+		`:syntax on` and `:filetype on` commands load the menu too).
+								*'go-g'*
+	  'g'	Grey menu items: Make menu items that are not active grey.  If
+		'g' is not included inactive menu items are not shown at all.
+								*'go-t'*
+	  't'	Include tearoff menu items.  Currently only works for Win32,
+		GTK+, and Motif 1.2 GUI.
+								*'go-T'*
+	  'T'	Include Toolbar.  Currently only in Win32, GTK+, Motif and
+		Photon GUIs.
+								*'go-r'*
+	  'r'	Right-hand scrollbar is always present.
+								*'go-R'*
+	  'R'	Right-hand scrollbar is present when there is a vertically
+		split window.
+								*'go-l'*
+	  'l'	Left-hand scrollbar is always present.
+								*'go-L'*
+	  'L'	Left-hand scrollbar is present when there is a vertically
+		split window.
+								*'go-b'*
+	  'b'	Bottom (horizontal) scrollbar is present.  Its size depends on
+		the longest visible line, or on the cursor line if the 'h'
+		flag is included. |gui-horiz-scroll|
+								*'go-h'*
+	  'h'	Limit horizontal scrollbar size to the length of the cursor
+		line.  Reduces computations. |gui-horiz-scroll|
+
+	And yes, you may even have scrollbars on the left AND the right if
+	you really want to :-).  See |gui-scrollbars| for more information.
+
+								*'go-v'*
+	  'v'	Use a vertical button layout for dialogs.  When not included,
+		a horizontal layout is preferred, but when it doesn't fit a
+		vertical layout is used anyway.  Not supported in GTK 3.
+								*'go-p'*
+	  'p'	Use Pointer callbacks for X11 GUI.  This is required for some
+		window managers.  If the cursor is not blinking or hollow at
+		the right moment, try adding this flag.  This must be done
+		before starting the GUI.  Set it in your |gvimrc|.  Adding or
+		removing it after the GUI has started has no effect.
+								*'go-F'*
+	  'F'	Add a footer.  Only for Motif.  See |gui-footer|.
+								*'go-k'*
+	  'k'	Keep the GUI window size when adding/removing a scrollbar, or
+		toolbar, tabline, etc.  Instead, the behavior is similar to
+		when the window is maximized and will adjust 'lines' and
+		'columns' to fit to the window.  Without the 'k' flag Vim will
+		try to keep 'lines' and 'columns' the same when adding and
+		removing GUI components.
+
+						*'guipty'* *'noguipty'*
+'guipty'		boolean	(default on)
+			global
+			{only available when compiled with GUI enabled}
+	Only in the GUI: If on, an attempt is made to open a pseudo-tty for
+	I/O to/from shell commands.  See |gui-pty|.
+
+						*'guitablabel'* *'gtl'*
+'guitablabel' 'gtl'	string	(default empty)
+			global
+			{only available when compiled with GUI enabled}
+	When non-empty describes the text to use in a label of the GUI tab
+	pages line.  When empty and when the result is empty Vim will use a
+	default label.  See |setting-guitablabel| for more info.
+
+	The format of this option is like that of 'statusline'.
+	'guitabtooltip' is used for the tooltip, see below.
+	The expression will be evaluated in the |sandbox| when set from a
+	modeline, see |sandbox-option|.
+	This option cannot be set in a modeline when 'modelineexpr' is off.
+
+	Only used when the GUI tab pages line is displayed.  'e' must be
+	present in 'guioptions'.  For the non-GUI tab pages line 'tabline' is
+	used.
+
+						*'guitabtooltip'* *'gtt'*
+'guitabtooltip' 'gtt'	string	(default empty)
+			global
+			{only available when compiled with GUI enabled}
+	When non-empty describes the text to use in a tooltip for the GUI tab
+	pages line.  When empty Vim will use a default tooltip.
+	This option is otherwise just like 'guitablabel' above.
+	You can include a line break.  Simplest method is to use |:let|: >
+		:let &guitabtooltip = "line one\nline two"
+<
+
+						*'helpfile'* *'hf'*
+'helpfile' 'hf'		string	(default (MS-Windows) "$VIMRUNTIME\doc\help.txt"
+					 (others) "$VIMRUNTIME/doc/help.txt")
+			global
+	Name of the main help file.  All distributed help files should be
+	placed together in one directory.  Additionally, all "doc" directories
+	in 'runtimepath' will be used.
+	Environment variables are expanded |:set_env|.  For example:
+	"$VIMRUNTIME/doc/help.txt".  If $VIMRUNTIME is not set, $VIM is also
+	tried.  Also see |$VIMRUNTIME| and |option-backslash| about including
+	spaces and backslashes.
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+						*'helpheight'* *'hh'*
+'helpheight' 'hh'	number	(default 20)
+			global
+	Minimal initial height of the help window when it is opened with the
+	":help" command.  The initial height of the help window is half of the
+	current window, or (when the 'ea' option is on) the same as other
+	windows.  When the height is less than 'helpheight', the height is
+	set to 'helpheight'.  Set to zero to disable.
+
+						*'helplang'* *'hlg'*
+'helplang' 'hlg'	string	(default: messages language or empty)
+			global
+			{only available when compiled with the |+multi_lang|
+			feature}
+	Comma-separated list of languages.  Vim will use the first language
+	for which the desired help can be found.  The English help will always
+	be used as a last resort.  You can add "en" to prefer English over
+	another language, but that will only find tags that exist in that
+	language and not in the English help.
+	Example: >
+		:set helplang=de,it
+<	This will first search German, then Italian and finally English help
+	files.
+	When using |CTRL-]| and ":help!" in a non-English help file Vim will
+	try to find the tag in the current language before using this option.
+	See |help-translated|.
+
+				     *'hidden'* *'hid'* *'nohidden'* *'nohid'*
+'hidden' 'hid'		boolean	(default off)
+			global
+	When off a buffer is unloaded when it is |abandon|ed.  When on a
+	buffer becomes hidden when it is |abandon|ed.  If the buffer is still
+	displayed in another window, it does not become hidden, of course.
+
+	The commands that move through the buffer list sometimes make a buffer
+	hidden even if the 'hidden' option is off when these three are true:
+	- the buffer is modified
+	- 'autowrite' is off or writing is not possible
+	- the '!' flag was used
+	Also see |windows.txt|.
+
+	To only make one buffer hidden use the 'bufhidden' option.
+	This option is set for one command with ":hide {command}" |:hide|.
+	WARNING: It's easy to forget that you have changes in hidden buffers.
+	Think twice when using ":q!" or ":qa!".
+
+						*'highlight'* *'hl'*

+			global
+	This option can be used to set highlighting mode for various
+	occasions.  It is a comma-separated list of character pairs.  The
+	first character in a pair gives the occasion, the second the mode to
+	use for that occasion.  The occasions are:
+	|hl-SpecialKey|	 8  Meta and special keys listed with ":map"

+	The default is used for occasions that are not included.
+	If you want to change what the display modes do, see |dos-colors|
+	for an example.
+	When using the ':' display mode, this must be followed by the name of
+	a highlight group.  A highlight group can be used to define any type
+	of highlighting, including using color.  See |:highlight| on how to
+	define one.  The default uses a different group for each occasion.
+	See |highlight-default| for the default highlight groups.
+
+						*'history'* *'hi'*
+'history' 'hi'		number	(Vim default: 50, Vi default: 0,
+						 set to 200 in |defaults.vim|)
+			global
+	A history of ":" commands, and a history of previous search patterns
+	is remembered.  This option decides how many entries may be stored in
+	each of these histories (see |cmdline-editing|).
+	The maximum value is 10000.
+	NOTE: This option is set to the Vi default value when 'compatible' is
+	set and to the Vim default value when 'compatible' is reset.
+
+					 *'hkmap'* *'hk'* *'nohkmap'* *'nohk'*
+'hkmap' 'hk'		boolean (default off)
+			global
+			{only available when compiled with the |+rightleft|
+			feature}
+	When on, the keyboard is mapped for the Hebrew character set.
+	Normally you would set 'allowrevins' and use CTRL-_ in insert mode to
+	toggle this option.  See |rileft.txt|.
+	NOTE: This option is reset when 'compatible' is set.
+
+				 *'hkmapp'* *'hkp'* *'nohkmapp'* *'nohkp'*
+'hkmapp' 'hkp'		boolean (default off)
+			global
+			{only available when compiled with the |+rightleft|
+			feature}
+	When on, phonetic keyboard mapping is used.  'hkmap' must also be on.
+	This is useful if you have a non-Hebrew keyboard.
+	See |rileft.txt|.
+	NOTE: This option is reset when 'compatible' is set.
+
+				 *'hlsearch'* *'hls'* *'nohlsearch'* *'nohls'*
+'hlsearch' 'hls'	boolean	(default off)
+			global
+			{not available when compiled without the
+			|+extra_search| feature}
+	When there is a previous search pattern, highlight all its matches.
+	The type of highlighting used can be set with the 'l' occasion in the
+	'highlight' option.  This uses the "Search" highlight group by
+	default.  Note that only the matching text is highlighted, any offsets
+	are not applied.  If the "CurSearch" highlight group is set then the
+	current match is highlighted with that.
+	See also: 'incsearch' and |:match|.
+	When you get bored looking at the highlighted matches, you can turn it
+	off with |:nohlsearch|.  This does not change the option value, as
+	soon as you use a search command, the highlighting comes back.
+	'redrawtime' specifies the maximum time spent on finding matches.
+	When the search pattern can match an end-of-line, Vim will try to
+	highlight all of the matched text.  However, this depends on where the
+	search starts.  This will be the first line in the window or the first
+	line below a closed fold.  A match in a previous line which is not
+	drawn may not continue in a newly drawn line.
+	You can specify whether the highlight status is restored on startup
+	with the 'h' flag in 'viminfo' |viminfo-h|.
+	NOTE: This option is reset when 'compatible' is set.
+
+						*'icon'* *'noicon'*
+'icon'			boolean	(default off, on when title can be restored)
+			global
+	When on, the icon text of the window will be set to the value of
+	'iconstring' (if it is not empty), or to the name of the file
+	currently being edited.  Only the last part of the name is used.
+	Overridden by the 'iconstring' option.
+	Only works if the terminal supports setting window icons (currently
+	only X11 GUI and terminals with a non-empty 't_IS' option - these are
+	Unix xterm and iris-ansi by default, where 't_IS' is taken from the
+	builtin termcap).
+	When Vim was compiled with HAVE_X11 defined, the original icon will be
+	restored if possible |X11|.  See |X11-icon| for changing the icon on
+	X11.
+	For MS-Windows the icon can be changed, see |windows-icon|.
+
+						*'iconstring'*
+'iconstring'		string	(default "")
+			global
+	When this option is not empty, it will be used for the icon text of
+	the window.  This happens only when the 'icon' option is on.
+	Only works if the terminal supports setting window icon text
+	(currently only X11 GUI and terminals with a non-empty 't_IS' option).
+	Does not work for MS-Windows.
+	When Vim was compiled with HAVE_X11 defined, the original icon will be
+	restored if possible |X11|.
+	When this option contains printf-style '%' items, they will be
+	expanded according to the rules used for 'statusline'.  See
+	'titlestring' for example settings.
+	This option cannot be set in a modeline when 'modelineexpr' is off.
+	{not available when compiled without the |+statusline| feature}
+
+			*'ignorecase'* *'ic'* *'noignorecase'* *'noic'*
+'ignorecase' 'ic'	boolean	(default off)
+			global
+	Ignore case in search patterns.  Also used when searching in the tags
+	file.
+	Also see 'smartcase' and 'tagcase'.
+	Can be overruled by using "\c" or "\C" in the pattern, see
+	|/ignorecase|.
+
+						*'imactivatefunc'* *'imaf'*
+'imactivatefunc' 'imaf'	string (default "")
+			global
+	This option specifies a function that will be called to
+	activate or deactivate the Input Method.  The value can be the name of
+	a function, a |lambda| or a |Funcref|. See |option-value-function| for
+	more information.
+	It is not used in the MS-Windows GUI version.
+	The expression will be evaluated in the |sandbox| when set from a
+	modeline, see |sandbox-option|.
+
+	Example: >
+		function ImActivateFunc(active)
+		  if a:active
+		    ... do something
+		  else
+		    ... do something
+		  endif
+		  " return value is not used
+		endfunction
+		set imactivatefunc=ImActivateFunc
+<
+						*'imactivatekey'* *'imak'*
+'imactivatekey' 'imak'	string (default "")
+			global
+			{only available when compiled with |+xim| and
+			|+GUI_GTK|}				*E599*
+	Specifies the key that your Input Method in X-Windows uses for
+	activation.  When this is specified correctly, vim can fully control
+	IM with 'imcmdline', 'iminsert' and 'imsearch'.
+	You can't use this option to change the activation key, the option
+	tells Vim what the key is.
+	Format:
+		[MODIFIER_FLAG-]KEY_STRING
+
+	These characters can be used for MODIFIER_FLAG (case is ignored):
+		S	    Shift key
+		L	    Lock key
+		C	    Control key
+		1	    Mod1 key
+		2	    Mod2 key
+		3	    Mod3 key
+		4	    Mod4 key
+		5	    Mod5 key
+	Combinations are allowed, for example "S-C-space" or "SC-space" are
+	both shift+ctrl+space.
+	See <X11/keysymdef.h> and XStringToKeysym for KEY_STRING.
+
+	Example: >
+		:set imactivatekey=S-space
+<	"S-space" means shift+space.  This is the activation key for kinput2 +
+	canna (Japanese), and ami (Korean).
+
+				*'imcmdline'* *'imc'* *'noimcmdline'* *'noimc'*
+'imcmdline' 'imc'	boolean (default off)
+			global
+	When set the Input Method is always on when starting to edit a command
+	line, unless entering a search pattern (see 'imsearch' for that).
+	Setting this option is useful when your input method allows entering
+	English characters directly, e.g., when it's used to type accented
+	characters with dead keys.
+
+				*'imdisable'* *'imd'* *'noimdisable'* *'noimd'*
+'imdisable' 'imd'	boolean (default off, on for some systems (SGI))
+			global
+	When set the Input Method is never used.  This is useful to disable
+	the IM when it doesn't work properly.
+	Currently this option is on by default for SGI/IRIX machines.  This
+	may change in later releases.
+
+						*'iminsert'* *'imi'*
+'iminsert' 'imi'	number (default 0)
+			local to buffer
+	Specifies whether :lmap or an Input Method (IM) is to be used in
+	Insert mode.  Valid values:
+		0	:lmap is off and IM is off
+		1	:lmap is ON and IM is off
+		2	:lmap is off and IM is ON
+	To always reset the option to zero when leaving Insert mode with <Esc>
+	this can be used: >
+		:inoremap <ESC> <ESC>:set iminsert=0<CR>
+<	This makes :lmap and IM turn off automatically when leaving Insert
+	mode.
+	Note that this option changes when using CTRL-^ in Insert mode
+	|i_CTRL-^|.
+	The value is set to 1 when setting 'keymap' to a valid keymap name.
+	It is also used for the argument of commands like "r" and "f".
+	The value 0 may not work correctly with Motif with some XIM
+	methods.  Use 'imdisable' to disable XIM then.
+
+	You can set 'imactivatefunc' and 'imstatusfunc' to handle IME/XIM
+	via external command if Vim is not compiled with the |+xim|,
+	|+multi_byte_ime| or |global-ime|.
+
+						*'imsearch'* *'ims'*
+'imsearch' 'ims'	number (default -1)
+			local to buffer
+	Specifies whether :lmap or an Input Method (IM) is to be used when
+	entering a search pattern.  Valid values:
+		-1	the value of 'iminsert' is used, makes it look like
+			'iminsert' is also used when typing a search pattern
+		0	:lmap is off and IM is off
+		1	:lmap is ON and IM is off
+		2	:lmap is off and IM is ON
+	Note that this option changes when using CTRL-^ in Command-line mode
+	|c_CTRL-^|.
+	The value is set to 1 when it is not -1 and setting the 'keymap'
+	option to a valid keymap name.
+	The value 0 may not work correctly with Motif with some XIM
+	methods.  Use 'imdisable' to disable XIM then.
+
+						*'imstatusfunc'* *'imsf'*
+'imstatusfunc' 'imsf'	string (default "")
+			global
+	This option specifies a function that is called to obtain the status
+	of Input Method.  It must return a positive number when IME is active.
+	The value can be the name of a function, a |lambda| or a |Funcref|.
+	See |option-value-function| for more information.
+	It is not used in the MS-Windows GUI version.
+
+	Example: >
+		function ImStatusFunc()
+		  let is_active = ...do something
+		  return is_active ? 1 : 0
+		endfunction
+		set imstatusfunc=ImStatusFunc
+<
+	NOTE: This function is invoked very often.  Keep it fast.
+	The expression will be evaluated in the |sandbox| when set from a
+	modeline, see |sandbox-option|.
+
+						*'imstyle'* *'imst'*
+'imstyle' 'imst'	number (default 1)
+			global
+			{only available when compiled with |+xim| and
+			|+GUI_GTK|}
+	This option specifies the input style of Input Method:
+	0   use on-the-spot style
+	1   over-the-spot style
+	See: |xim-input-style|
+
+	For a long time on-the-spot style had been used in the GTK version of
+	vim, however, it is known that it causes troubles when using mappings,
+	|single-repeat|, etc.  Therefore over-the-spot style becomes the
+	default now.  This should work fine for most people, however if you
+	have any problem with it, try using on-the-spot style.
+	The expression will be evaluated in the |sandbox| when set from a
+	modeline, see |sandbox-option|.
+
+						*'include'* *'inc'*
+'include' 'inc'		string	(default "^\s*#\s*include")
+			global or local to buffer |global-local|
+			{not available when compiled without the
+			|+find_in_path| feature}
+	Pattern to be used to find an include command.  It is a search
+	pattern, just like for the "/" command (See |pattern|).  The default
+	value is for C programs.  This option is used for the commands "[i",
+	"]I", "[d", etc.
+	Normally the 'isfname' option is used to recognize the file name that
+	comes after the matched pattern.  But if "\zs" appears in the pattern
+	then the text matched from "\zs" to the end, or until "\ze" if it
+	appears, is used as the file name.  Use this to include characters
+	that are not in 'isfname', such as a space.  You can then use
+	'includeexpr' to process the matched text.
+	See |option-backslash| about including spaces and backslashes.
+
+						*'includeexpr'* *'inex'*
+'includeexpr' 'inex'	string	(default "")
+			local to buffer
+			{not available when compiled without the
+			|+find_in_path| or |+eval| features}
+	Expression to be used to transform the string found with the 'include'
+	option to a file name.  Mostly useful to change "." to "/" for Java: >
+		:setlocal includeexpr=substitute(v:fname,'\\.','/','g')
+<	The "v:fname" variable will be set to the file name that was detected.
+	Note the double backslash: the `:set` command first halves them, then
+	one remains it the value, where "\." matches a dot literally.  For
+	simple character replacements `tr()` avoids the need for escaping: >
+		:setlocal includeexpr=tr(v:fname,'.','/')
+<
+	Also used for the |gf| command if an unmodified file name can't be
+	found.  Allows doing "gf" on the name after an 'include' statement.
+	Also used for |<cfile>|.
+
+	If the expression starts with s: or |<SID>|, then it is replaced with
+	the script ID (|local-function|). Example: >
+		setlocal includeexpr=s:MyIncludeExpr()
+		setlocal includeexpr=<SID>SomeIncludeExpr()
+<	Otherwise, the expression is evaluated in the context of the script
+	where the option was set, thus script-local items are available.
+
+	It is more efficient if the value is just a function call without
+	arguments, see |expr-option-function|.
+
+	The expression will be evaluated in the |sandbox| when set from a
+	modeline, see |sandbox-option|.
+	This option cannot be set in a modeline when 'modelineexpr' is off.
+
+	It is not allowed to change text or jump to another window while
+	evaluating 'includeexpr' |textlock|.
+
+				 *'incsearch'* *'is'* *'noincsearch'* *'nois'*
+'incsearch' 'is'	boolean	(default off, set in |defaults.vim| if the
+					    |+reltime| feature is supported)
+			global
+			{not available when compiled without the
+			|+extra_search| features}
+	While typing a search command, show where the pattern, as it was typed
+	so far, matches.  The matched string is highlighted.  If the pattern
+	is invalid or not found, nothing is shown.  The screen will be updated
+	often, this is only useful on fast terminals.
+	Also applies to the pattern in commands: >
+		:global
+		:lvimgrep
+		:lvimgrepadd
+		:smagic
+		:snomagic
+		:sort
+		:substitute
+		:vglobal
+		:vimgrep
+		:vimgrepadd
+<	Note that the match will be shown, but the cursor will return to its
+	original position when no match is found and when pressing <Esc>.  You
+	still need to finish the search command with <Enter> to move the
+	cursor to the match.
+	You can use the CTRL-G and CTRL-T keys to move to the next and
+	previous match. |c_CTRL-G| |c_CTRL-T|
+	When compiled with the |+reltime| feature Vim only searches for about
+	half a second.  With a complicated pattern and/or a lot of text the
+	match may not be found.  This is to avoid that Vim hangs while you
+	are typing the pattern.
+	The highlighting can be set with the 'i' flag in 'highlight'.
+	When 'hlsearch' is on, all matched strings are highlighted too while
+	typing a search command. See also: 'hlsearch'.
+	If you don't want to turn 'hlsearch' on, but want to highlight all
+	matches while searching, you can turn on and off 'hlsearch' with
+	autocmd.  Example: >
+		augroup vimrc-incsearch-highlight
+		  autocmd!
+		  autocmd CmdlineEnter /,\? :set hlsearch
+		  autocmd CmdlineLeave /,\? :set nohlsearch
+		augroup END
+<
+	CTRL-L can be used to add one character from after the current match
+	to the command line.  If 'ignorecase' and 'smartcase' are set and the
+	command line has no uppercase characters, the added character is
+	converted to lowercase.
+	CTRL-R CTRL-W can be used to add the word at the end of the current
+	match, excluding the characters that were already typed.
+	NOTE: This option is reset when 'compatible' is set.
+
+						*'indentexpr'* *'inde'*
+'indentexpr' 'inde'	string	(default "")
+			local to buffer
+			{not available when compiled without the |+eval|
+			feature}
+	Expression which is evaluated to obtain the proper indent for a line.
+	It is used when a new line is created, for the |=| operator and
+	in Insert mode as specified with the 'indentkeys' option.
+	When this option is not empty, it overrules the 'cindent' and
+	'smartindent' indenting.  When 'lisp' is set, this option is
+	is only used when 'lispoptions' contains "expr:1".
+	When 'paste' is set this option is not used for indenting.
+	The expression is evaluated with |v:lnum| set to the line number for
+	which the indent is to be computed.  The cursor is also in this line
+	when the expression is evaluated (but it may be moved around).
+
+	If the expression starts with s: or |<SID>|, then it is replaced with
+	the script ID (|local-function|). Example: >
+		set indentexpr=s:MyIndentExpr()
+		set indentexpr=<SID>SomeIndentExpr()
+<	Otherwise, the expression is evaluated in the context of the script
+	where the option was set, thus script-local items are available.
+
+	The advantage of using a function call without arguments is that it is
+	faster, see |expr-option-function|.
+
+	The expression must return the number of spaces worth of indent.  It
+	can return "-1" to keep the current indent (this means 'autoindent' is
+	used for the indent).
+	Functions useful for computing the indent are |indent()|, |cindent()|
+	and |lispindent()|.
+	The evaluation of the expression must not have side effects!  It must
+	not change the text, jump to another window, etc.  Afterwards the
+	cursor position is always restored, thus the cursor may be moved.
+	Normally this option would be set to call a function: >
+		:set indentexpr=GetMyIndent()
+<	Error messages will be suppressed, unless the 'debug' option contains
+	"msg".
+	See |indent-expression|.
+	NOTE: This option is set to "" when 'compatible' is set.
+
+	The expression will be evaluated in the |sandbox| when set from a
+	modeline, see |sandbox-option|.
+	This option cannot be set in a modeline when 'modelineexpr' is off.
+
+	It is not allowed to change text or jump to another window while
+	evaluating 'indentexpr' |textlock|.
+
+
+						*'indentkeys'* *'indk'*
+'indentkeys' 'indk'	string	(default "0{,0},0),0],:,0#,!^F,o,O,e")
+			local to buffer
+	A list of keys that, when typed in Insert mode, cause reindenting of
+	the current line.  Only happens if 'indentexpr' isn't empty.
+	The format is identical to 'cinkeys', see |indentkeys-format|.
+	See |C-indenting| and |indent-expression|.
+
+			*'infercase'* *'inf'* *'noinfercase'* *'noinf'*
+'infercase' 'inf'	boolean	(default off)
+			local to buffer
+	When doing keyword completion in insert mode |ins-completion|, and
+	'ignorecase' is also on, the case of the match is adjusted depending
+	on the typed text.  If the typed text contains a lowercase letter
+	where the match has an upper case letter, the completed part is made
+	lowercase.  If the typed text has no lowercase letters and the match
+	has a lowercase letter where the typed text has an uppercase letter,
+	and there is a letter before it, the completed part is made uppercase.
+	With 'noinfercase' the match is used as-is.
+
+			*'insertmode'* *'im'* *'noinsertmode'* *'noim'*
+'insertmode' 'im'	boolean	(default off)
+			global
+	Makes Vim work in a way that Insert mode is the default mode.  Useful
+	if you want to use Vim as a modeless editor.  Used for |evim|.
+	These Insert mode commands will be useful:
+	- Use the cursor keys to move around.
+	- Use CTRL-O to execute one Normal mode command |i_CTRL-O|.  When
+	  this is a mapping, it is executed as if 'insertmode' was off.
+	  Normal mode remains active until the mapping is finished.
+	- Use CTRL-L to execute a number of Normal mode commands, then use
+	  <Esc> to get back to Insert mode.  Note that CTRL-L moves the cursor
+	  left, like <Esc> does when 'insertmode' isn't set.  |i_CTRL-L|
+
+	These items change when 'insertmode' is set:
+	- when starting to edit of a file, Vim goes to Insert mode.
+	- <Esc> in Insert mode is a no-op and beeps.
+	- <Esc> in Normal mode makes Vim go to Insert mode.
+	- CTRL-L in Insert mode is a command, it is not inserted.
+	- CTRL-Z in Insert mode suspends Vim, see |CTRL-Z|.	*i_CTRL-Z*
+	However, when <Esc> is used inside a mapping, it behaves like
+	'insertmode' was not set.  This was done to be able to use the same
+	mappings with 'insertmode' set or not set.
+	When executing commands with |:normal| 'insertmode' is not used.
+
+	NOTE: This option is reset when 'compatible' is set.
+
+						*'isfname'* *'isf'*
+'isfname' 'isf'		string	(default for Win32:
+			     "@,48-57,/,\,.,-,_,+,,,#,$,%,{,},[,],:,@-@,!,~,="
+			    for AMIGA: "@,48-57,/,.,-,_,+,,,$,:"

+			    for OS/390: "@,240-249,/,.,-,_,+,,,#,$,%,~,="
+			    otherwise: "@,48-57,/,.,-,_,+,,,#,$,%,~,=")
+			global
+	The characters specified by this option are included in file names and
+	path names.  Filenames are used for commands like "gf", "[i" and in
+	the tags file.  It is also used for "\f" in a |pattern|.
+	Multi-byte characters 256 and above are always included, only the
+	characters up to 255 are specified with this option.
+	For UTF-8 the characters 0xa0 to 0xff are included as well.
+	Think twice before adding white space to this option.  Although a
+	space may appear inside a file name, the effect will be that Vim
+	doesn't know where a file name starts or ends when doing completion.
+	It most likely works better without a space in 'isfname'.
+
+	Note that on systems using a backslash as path separator, Vim tries to
+	do its best to make it work as you would expect.  That is a bit
+	tricky, since Vi originally used the backslash to escape special
+	characters.  Vim will not remove a backslash in front of a normal file
+	name character on these systems, but it will on Unix and alikes.  The
+	'&' and '^' are not included by default, because these are special for
+	cmd.exe.
+
+	The format of this option is a list of parts, separated with commas.
+	Each part can be a single character number or a range.  A range is two
+	character numbers with '-' in between.  A character number can be a
+	decimal number between 0 and 255 or the ASCII character itself (does
+	not work for digits).  Example:
+		"_,-,128-140,#-43"	(include '_' and '-' and the range
+					128 to 140 and '#' to 43)
+	If a part starts with '^', the following character number or range
+	will be excluded from the option.  The option is interpreted from left
+	to right.  Put the excluded character after the range where it is
+	included.  To include '^' itself use it as the last character of the
+	option or the end of a range.  Example:
+		"^a-z,#,^"	(exclude 'a' to 'z', include '#' and '^')
+	If the character is '@', all characters where isalpha() returns TRUE
+	are included.  Normally these are the characters a to z and A to Z,
+	plus accented characters.  To include '@' itself use "@-@".  Examples:
+		"@,^a-z"	All alphabetic characters, excluding lower
+				case ASCII letters.
+		"a-z,A-Z,@-@"	All letters plus the '@' character.
+	A comma can be included by using it where a character number is
+	expected.  Example:
+		"48-57,,,_"	Digits, comma and underscore.
+	A comma can be excluded by prepending a '^'.  Example:
+		" -~,^,,9"	All characters from space to '~', excluding
+				comma, plus <Tab>.
+	See |option-backslash| about including spaces and backslashes.
+
+						*'isident'* *'isi'*
+'isident' 'isi'		string	(default for Win32:
+					   "@,48-57,_,128-167,224-235"
+				otherwise: "@,48-57,_,192-255")
+			global
+	The characters given by this option are included in identifiers.
+	Identifiers are used in recognizing environment variables and after a
+	match of the 'define' option.  It is also used for "\i" in a
+	|pattern|.  See 'isfname' for a description of the format of this
+	option.  For '@' only characters up to 255 are used.
+	Careful: If you change this option, it might break expanding
+	environment variables.  E.g., when '/' is included and Vim tries to
+	expand "$HOME/.viminfo".  Maybe you should change 'iskeyword' instead.
+
+						*'iskeyword'* *'isk'*
+'iskeyword' 'isk'	string (Vim default for Win32:
+					    "@,48-57,_,128-167,224-235"
+				   otherwise:  "@,48-57,_,192-255"
+				Vi default: "@,48-57,_")
+			local to buffer
+	Keywords are used in searching and recognizing with many commands:
+	"w", "*", "[i", etc.  It is also used for "\k" in a |pattern|.  See
+	'isfname' for a description of the format of this option.  For '@'
+	characters above 255 check the "word" character class (any character
+	that is not white space or punctuation).
+	For C programs you could use "a-z,A-Z,48-57,_,.,-,>".
+	For a help file it is set to all non-blank printable characters except
+	'*', '"' and '|' (so that CTRL-] on a command finds the help for that
+	command).
+	When the 'lisp' option is on the '-' character is always included.
+	This option also influences syntax highlighting, unless the syntax
+	uses |:syn-iskeyword|.
+	NOTE: This option is set to the Vi default value when 'compatible' is
+	set and to the Vim default value when 'compatible' is reset.
+
+						*'isprint'* *'isp'*
+'isprint' 'isp'	string	(default for Win32 and macOS:
+				"@,~-255"; otherwise: "@,161-255")
+			global
+	The characters given by this option are displayed directly on the
+	screen.  It is also used for "\p" in a |pattern|.  The characters from
+	space (ASCII 32) to '~' (ASCII 126) are always displayed directly,
+	even when they are not included in 'isprint' or excluded.  See
+	'isfname' for a description of the format of this option.
+
+	Non-printable characters are displayed with two characters:
+		  0 -  31	"^@" - "^_"
+		 32 - 126	always single characters
+		   127		"^?"
+		128 - 159	"~@" - "~_"
+		160 - 254	"| " - "|~"
+		   255		"~?"
+	When 'encoding' is a Unicode one, illegal bytes from 128 to 255 are
+	displayed as <xx>, with the hexadecimal value of the byte.
+	When 'display' contains "uhex" all unprintable characters are
+	displayed as <xx>.
+	The SpecialKey highlighting will be used for unprintable characters.
+	|hl-SpecialKey|
+
+	Multi-byte characters 256 and above are always included, only the
+	characters up to 255 are specified with this option.  When a character
+	is printable but it is not available in the current font, a
+	replacement character will be shown.
+	Unprintable and zero-width Unicode characters are displayed as <xxxx>.
+	There is no option to specify these characters.
+
+			*'joinspaces'* *'js'* *'nojoinspaces'* *'nojs'*
+'joinspaces' 'js'	boolean	(default on)
+			global
+	Insert two spaces after a '.', '?' and '!' with a join command.
+	When 'cpoptions' includes the 'j' flag, only do this after a '.'.
+	Otherwise only one space is inserted.
+	NOTE: This option is set when 'compatible' is set.
+
+							*'key'*
+'key'			string	(default "")
+			local to buffer
+			{only available when compiled with the |+cryptv|
+			feature}
+	The key that is used for encrypting and decrypting the current buffer.
+	See |encryption| and 'cryptmethod'.
+	Careful: Do not set the key value by hand, someone might see the typed
+	key.  Use the |:X| command.  But you can make 'key' empty: >
+		:set key=
+<	It is not possible to get the value of this option with ":set key" or
+	"echo &key".  This is to avoid showing it to someone who shouldn't
+	know.  It also means you cannot see it yourself once you have set it,
+	be careful not to make a typing error!
+	You can use "&key" in an expression to detect whether encryption is
+	enabled.  When 'key' is set it returns "*****" (five stars).
+
+					*'keymap'* *'kmp'* *E544*
+'keymap' 'kmp'		string	(default "")
+			local to buffer
+			{only available when compiled with the |+keymap|
+			feature}
+	Name of a keyboard mapping.  See |mbyte-keymap|.
+	Setting this option to a valid keymap name has the side effect of
+	setting 'iminsert' to one, so that the keymap becomes effective.
+	'imsearch' is also set to one, unless it was -1
+	Only normal file name characters can be used, "/\*?[|<>" are illegal.
+
+					*'keymodel'* *'km'*
+'keymodel' 'km'		string	(default "")
+			global
+	List of comma-separated words, which enable special things that keys
+	can do.  These values can be used:
+	   startsel	Using a shifted special key starts selection (either
+			Select mode or Visual mode, depending on "key" being
+			present in 'selectmode').
+	   stopsel	Using a not-shifted special key stops selection.
+	Special keys in this context are the cursor keys, <End>, <Home>,
+	<PageUp> and <PageDown>.
+	The 'keymodel' option is set by the |:behave| command.
+
+						*'keyprotocol'* *'kpc'*
+'keyprotocol' 'kpc'	string	(default: see below)
+			global
+	Specifies what keyboard protocol to use depending on the value of
+	'term'.  The supported keyboard protocols names are:
+		none	whatever the terminal uses
+		mok2	modifyOtherKeys level 2, as supported by xterm
+		kitty	Kitty keyboard protocol, as supported by Kitty
+
+	The option value is a list of comma separated items.  Each item has
+	a pattern that is matched against the 'term' option, a colon and the
+	protocol name to be used.  To illustrate this, the default value would
+	be set with: >
+	   set keyprotocol=kitty:kitty,foot:kitty,wezterm:kitty,xterm:mok2
+
+<	This means that when 'term' contains "kitty, "foot" or "wezterm"
+	somewhere then the "kitty" protocol is used.  When 'term' contains
+	"xterm" somewhere, then the "mok2" protocol is used.
+
+	The first match is used, thus if you want to have "kitty" use the
+	kitty protocol, but "badkitty" not, then you should match "badkitty"
+	first and use the "none" value: >
+	   set keyprotocol=badkitty:none,kitty:kitty
+<
+	The option is used after 'term' has been changed.  First the termcap
+	entries are set, possibly using the builtin list, see |builtin-terms|.
+	Then this option is inspected and if there is a match and a protocol
+	is specified the following happens:
+		none	Nothing, the regular t_TE and t_TI values remain
+
+		mok2	The t_TE value is changed to:
+			    CSI >4;m	disables modifyOtherKeys
+			The t_TI value is changed to:
+			    CSI >4;2m	enables modifyOtherKeys
+			    CSI ?4m	request the modifyOtherKeys state
+
+		kitty	The t_TE value is changed to:
+			    CSI >4;m	disables modifyOtherKeys
+			    CSI =0;1u	disables the kitty keyboard protocol
+			The t_TI value is changed to:
+			    CSI =1;1u	enables the kitty keyboard protocol
+			    CSI ?u	request kitty keyboard protocol state
+			    CSI >c	request the termresponse
+
+	If you notice problems, such as characters being displayed that
+	disappear after `CTRL-L`, you might want to try making this option
+	empty.  Then set the 'term' option to have it take effect: >
+		set keyprotocol=
+		let &term = &term
+<
+
+					*'keywordprg'* *'kp'*
+'keywordprg' 'kp'	string	(default "man" or "man -s",  DOS: ":help",
+								  VMS: "help")
+			global or local to buffer |global-local|
+	Program to use for the |K| command.  Environment variables are
+	expanded |:set_env|.  ":help" may be used to access the Vim internal
+	help.  (Note that previously setting the global option to the empty
+	value did this, which is now deprecated.)
+	When the first character is ":", the command is invoked as a Vim
+	Ex command with [count] added as an argument if it is not zero.
+	When "man", "man -s" or an Ex command is used, Vim will automatically
+	translate a count for the "K" command and pass it as the first
+	argument.  For "man -s" the "-s" is removed when there is no count.
+	See |option-backslash| about including spaces and backslashes.
+	Example: >
+		:set keywordprg=man\ -s
+<	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+					*'langmap'* *'lmap'* *E357* *E358*
+'langmap' 'lmap'	string	(default "")
+			global
+			{only available when compiled with the |+langmap|
+			feature}
+	This option allows switching your keyboard into a special language
+	mode.  When you are typing text in Insert mode the characters are
+	inserted directly.  When in Normal mode the 'langmap' option takes
+	care of translating these special characters to the original meaning
+	of the key.  This means you don't have to change the keyboard mode to
+	be able to execute Normal mode commands.
+	This is the opposite of the 'keymap' option, where characters are
+	mapped in Insert mode.
+	Also consider setting 'langremap' to off, to prevent 'langmap' from
+	applying to characters resulting from a mapping.
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+	Example (for Greek, in UTF-8):				*greek*  >
+	    :set langmap=ΑA,ΒB,ΨC,ΔD,ΕE,ΦF,ΓG,ΗH,ΙI,ΞJ,ΚK,ΛL,ΜM,ΝN,ΟO,ΠP,QQ,ΡR,ΣS,ΤT,ΘU,ΩV,WW,ΧX,ΥY,ΖZ,αa,βb,ψc,δd,εe,φf,γg,ηh,ιi,ξj,κk,λl,μm,νn,οo,πp,qq,ρr,σs,τt,θu,ωv,ςw,χx,υy,ζz
+<	Example (exchanges meaning of z and y for commands): >
+	    :set langmap=zy,yz,ZY,YZ
+<
+	The 'langmap' option is a list of parts, separated with commas.  Each
+	part can be in one of two forms:
+	1.  A list of pairs.  Each pair is a "from" character immediately
+	    followed by the "to" character.  Examples: "aA", "aAbBcC".
+	2.  A list of "from" characters, a semi-colon and a list of "to"
+	    characters.  Example: "abc;ABC"
+	Example: "aA,fgh;FGH,cCdDeE"
+	Special characters need to be preceded with a backslash.  These are
+	";", ',', '"', '|' and backslash itself.
+
+	This will allow you to activate vim actions without having to switch
+	back and forth between the languages.  Your language characters will
+	be understood as normal vim English characters (according to the
+	langmap mappings) in the following cases:
+	 o Normal/Visual mode (commands, buffer/register names, user mappings)
+	 o Insert/Replace Mode: Register names after CTRL-R
+	 o Insert/Replace Mode: Mappings
+	Characters entered in Command-line mode will NOT be affected by
+	this option.   Note that this option can be changed at any time
+	allowing to switch between mappings for different languages/encodings.
+	Use a mapping to avoid having to type it each time!
+
+					*'langmenu'* *'lm'*
+'langmenu' 'lm'		string	(default "")
+			global
+			{only available when compiled with the |+menu| and
+			|+multi_lang| features}
+	Language to use for menu translation.  Tells which file is loaded
+	from the "lang" directory in 'runtimepath': >
+		"lang/menu_" .. &langmenu .. ".vim"
+<	(without the spaces).  For example, to always use the Dutch menus, no
+	matter what $LANG is set to: >
+		:set langmenu=nl_NL.ISO_8859-1
+<	When 'langmenu' is empty, |v:lang| is used.
+	Only normal file name characters can be used, "/\*?[|<>" are illegal.
+	If your $LANG is set to a non-English language but you do want to use
+	the English menus: >
+		:set langmenu=none
+<	This option must be set before loading menus, switching on filetype
+	detection or syntax highlighting.  Once the menus are defined setting
+	this option has no effect.  But you could do this: >
+		:source $VIMRUNTIME/delmenu.vim
+		:set langmenu=de_DE.ISO_8859-1
+		:source $VIMRUNTIME/menu.vim
+<	Warning: This deletes all menus that you defined yourself!
+
+			*'langnoremap'* *'lnr'* *'nolangnoremap'* *'nolnr'*
+'langnoremap' 'lnr'	boolean (default off, set in |defaults.vim|)
+			global
+			{only available when compiled with the |+langmap|
+			feature}
+	This is just like 'langremap' but with the value inverted.  It only
+	exists for backwards compatibility.  When setting 'langremap' then
+	'langnoremap' is set to the inverted value, and the other way around.
+
+			*'langremap'* *'lrm'* *'nolangremap'* *'nolrm'*
+'langremap' 'lrm'	boolean (default on, set to off in |defaults.vim|)
+			global
+			{only available when compiled with the |+langmap|
+			feature}
+	When off, setting 'langmap' does not apply to characters resulting from
+	a mapping.  This basically means, if you noticed that setting
+	'langmap' disables some of your mappings, try resetting this option.
+	This option defaults to on for backwards compatibility.  Set it off if
+	that works for you to avoid mappings to break.
+
+					*'laststatus'* *'ls'*
+'laststatus' 'ls'	number	(default 1)
+			global
+	The value of this option influences when the last window will have a
+	status line:
+		0: never
+		1: only if there are at least two windows
+		2: always
+	The screen looks nicer with a status line if you have several
+	windows, but it takes another screen line. |status-line|
+
+			*'lazyredraw'* *'lz'* *'nolazyredraw'* *'nolz'*
+'lazyredraw' 'lz'	boolean	(default off)
+			global
+	When this option is set, the screen will not be redrawn while
+	executing macros, registers and other commands that have not been
+	typed.  Also, updating the window title is postponed.  To force an
+	update use |:redraw|.
+	This may occasionally cause display errors.  It is only meant to be set
+	temporarily when performing an operation where redrawing may cause
+	flickering or cause a slow down.
+
+			*'linebreak'* *'lbr'* *'nolinebreak'* *'nolbr'*
+'linebreak' 'lbr'	boolean	(default off)
+			local to window
+			{not available when compiled without the |+linebreak|
+			feature}
+	If on, Vim will wrap long lines at a character in 'breakat' rather
+	than at the last character that fits on the screen.  Unlike
+	'wrapmargin' and 'textwidth', this does not insert <EOL>s in the file,
+	it only affects the way the file is displayed, not its contents.
+	If 'breakindent' is set, line is visually indented. Then, the value
+	of 'showbreak' is used to put in front of wrapped lines. This option
+	is not used when the 'wrap' option is off.
+	Note that <Tab> characters after an <EOL> are mostly not displayed
+	with the right amount of white space.
+
+						*'lines'* *E593*
+'lines'			number	(default 24 or terminal height)
+			global
+	Number of lines of the Vim window.
+	Normally you don't need to set this.  It is done automatically by the
+	terminal initialization code.  Also see |posix-screen-size|.
+	When Vim is running in the GUI or in a resizable window, setting this
+	option will cause the window size to be changed.  When you only want
+	to use the size for the GUI, put the command in your |gvimrc| file.
+	Vim limits the number of lines to what fits on the screen.  You can
+	use this command to get the tallest window possible: >
+		:set lines=999
+<	Minimum value is 2, maximum value is 1000.
+	If you get fewer lines than expected, check the 'guiheadroom' option.
+	When you set this option and Vim is unable to change the physical
+	number of lines of the display, the display may be messed up.
+
+						*'linespace'* *'lsp'*
+'linespace' 'lsp'	number	(default 0, 1 for Win32 GUI)
+			global
+			{only in the GUI}
+	Number of pixel lines inserted between characters.  Useful if the font
+	uses the full character cell height, making lines touch each other.
+	When non-zero there is room for underlining.
+	With some fonts there can be too much room between lines (to have
+	space for ascents and descents).  Then it makes sense to set
+	'linespace' to a negative value.  This may cause display problems
+	though!
+
+						*'lisp'* *'nolisp'*
+'lisp'			boolean	(default off)
+			local to buffer
+	Lisp mode: When <Enter> is typed in insert mode set the indent for
+	the next line to Lisp standards (well, sort of).  Also happens with
+	"cc" or "S".  'autoindent' must also be on for this to work.  The 'p'
+	flag in 'cpoptions' changes the method of indenting: Vi compatible or
+	better.  Also see 'lispwords'.
+	The '-' character is included in keyword characters.  Redefines the
+	"=" operator to use this same indentation algorithm rather than
+	calling an external program if 'equalprg' is empty.
+	This option is not used when 'paste' is set.
+
+						*'lispoptions'* *'lop'*
+'lispoptions' 'lop'	string	(default "")
+			local to buffer
+	Comma-separated list of items that influence the Lisp indenting when
+	enabled with the |'lisp'| option.  Currently only one item is
+	supported:
+		expr:1	use 'indentexpr' for Lisp indenting when it is set
+		expr:0	do not use 'indentexpr' for Lisp indenting (default)
+	Note that when using 'indentexpr' the `=` operator indents all the
+	lines, otherwise the first line is not indented (Vi-compatible).
+
+						*'lispwords'* *'lw'*
+'lispwords' 'lw'	string	(default is very long)
+			global or local to buffer |global-local|
+	Comma-separated list of words that influence the Lisp indenting when
+	enabled with the |'lisp'| option.
+
+						*'list'* *'nolist'*
+'list'			boolean	(default off)
+			local to window
+	List mode: By default show tabs as CTRL-I is displayed, display $
+	after end of line.  Useful to see the difference between tabs and
+	spaces and for trailing blanks.  Further changed by the 'listchars'
+	option.
+
+	The cursor is displayed at the start of the space a Tab character
+	occupies, not at the end as usual in Normal mode.  To get this cursor
+	position while displaying Tabs with spaces, use: >
+		:set list lcs=tab:\ \ 
+<
+	Note that list mode will also affect formatting (set with 'textwidth'
+	or 'wrapmargin') when 'cpoptions' includes 'L'.  See 'listchars' for
+	changing the way tabs are displayed.
+
+						*'listchars'* *'lcs'*
+'listchars' 'lcs'	string	(default "eol:$")
+			global or local to window |global-local|
+	Strings to use in 'list' mode and for the |:list| command.  It is a
+	comma-separated list of string settings.
+							*lcs-eol*
+	  eol:c		Character to show at the end of each line.  When
+			omitted, there is no extra character at the end of the
+			line.
+							*lcs-tab*
+	  tab:xy[z]	Two or three characters to be used to show a tab.
+			The third character is optional.
+
+	  tab:xy	The 'x' is always used, then 'y' as many times as will
+			fit.  Thus "tab:>-" displays:
+				>
+				>-
+				>--
+				etc.
+
+	  tab:xyz	The 'z' is always used, then 'x' is prepended, and
+			then 'y' is used as many times as will fit.  Thus
+			"tab:<->" displays:
+				>
+				<>
+				<->
+				<-->
+				etc.
+
+			When "tab:" is omitted, a tab is shown as ^I.
+							*lcs-space*
+	  space:c	Character to show for a space.  When omitted, spaces
+			are left blank.
+							*lcs-multispace*
+	  multispace:c...
+			One or more characters to use cyclically to show for
+			multiple consecutive spaces.  Overrides the "space"
+			setting, except for single spaces.  When omitted, the
+			"space" setting is used.  For example,
+			`:set listchars=multispace:---+` shows ten consecutive
+			spaces as:
+				---+---+-- ~
+							*lcs-lead*
+	  lead:c	Character to show for leading spaces.  When omitted,
+			leading spaces are blank.  Overrides the "space" and
+			"multispace" settings for leading spaces.  You can
+			combine it with "tab:", for example: >
+				:set listchars+=tab:>-,lead:.
+<							*lcs-leadmultispace*
+	  leadmultispace:c...
+			Like the |lcs-multispace| value, but for leading
+			spaces only.  Also overrides |lcs-lead| for leading
+			multiple spaces.
+			`:set listchars=leadmultispace:---+` shows ten
+			consecutive leading spaces as:
+				---+---+--XXX ~
+			Where "XXX" denotes the first non-blank characters in
+			the line.
+							*lcs-trail*
+	  trail:c	Character to show for trailing spaces.  When omitted,
+			trailing spaces are blank.  Overrides the "space" and
+			"multispace" settings for trailing spaces.
+							*lcs-extends*
+	  extends:c	Character to show in the last column, when 'wrap' is
+			off and the line continues beyond the right of the
+			screen.
+							*lcs-precedes*
+	  precedes:c	Character to show in the first visible column of the
+			physical line, when there is text preceding the
+			character visible in the first column.
+							*lcs-conceal*
+	  conceal:c	Character to show in place of concealed text, when
+			'conceallevel' is set to 1.
+							*lcs-nbsp*
+	  nbsp:c	Character to show for a non-breakable space character
+			(0xA0 (160 decimal) and U+202F).  Left blank when
+			omitted.
+
+	The characters ':' and ',' should not be used.  UTF-8 characters can
+	be used when 'encoding' is "utf-8", otherwise only printable
+	characters are allowed.  All characters must be single width.
+
+	Each character can be specified as hex: >
+		set listchars=eol:\\x24
+		set listchars=eol:\\u21b5
+		set listchars=eol:\\U000021b5
+<	Note that a double backslash is used.  The number of hex characters
+	must be exactly 2 for \\x, 4 for \\u and 8 for \\U.
+
+	Examples: >
+	    :set lcs=tab:>-,trail:-
+	    :set lcs=tab:>-,eol:<,nbsp:%
+	    :set lcs=extends:>,precedes:<
+<	The "NonText" highlighting will be used for "eol", "extends" and
+	"precedes".  "SpecialKey" will be used for "tab", "nbsp", "space",
+	"multispace", "lead" and "trail".
+	|hl-NonText| |hl-SpecialKey|
+
+			*'lpl'* *'nolpl'* *'loadplugins'* *'noloadplugins'*
+'loadplugins' 'lpl'	boolean	(default on)
+			global
+	When on the plugin scripts are loaded when starting up |load-plugins|.
+	This option can be reset in your |vimrc| file to disable the loading
+	of plugins.
+	Note that using the "-u NONE", "-u DEFAULTS" and "--noplugin" command
+	line arguments reset this option.  See |-u| and |--noplugin|.
+
+						*'luadll'*
+'luadll'		string	(default depends on the build)
+			global
+			{only available when compiled with the |+lua/dyn|
+			feature}
+	Specifies the name of the Lua shared library. The default is
+	DYNAMIC_LUA_DLL, which was specified at compile time.
+	Environment variables are expanded |:set_env|.
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+						*'macatsui'* *'nomacatsui'*
+'macatsui'		boolean	(default on)
+			global
+			{not supported}
+	No longer supported, as the Mac OS X GUI code was removed.
+
+						*'magic'* *'nomagic'*
+'magic'			boolean	(default on)
+			global
+	Changes the special characters that can be used in search patterns.
+	See |pattern|.
+	WARNING: Switching this option off most likely breaks plugins!  That
+	is because many patterns assume it's on and will fail when it's off.
+	Only switch it off when working with old Vi scripts.  In any other
+	situation write patterns that work when 'magic' is on.  Include "\M"
+	when you want to |/\M|.
+	In |Vim9| script the value of 'magic' is ignored, patterns behave like
+	it is always set.
+
+						*'makeef'* *'mef'*
+'makeef' 'mef'		string	(default: "")
+			global
+			{not available when compiled without the |+quickfix|
+			feature}
+	Name of the errorfile for the |:make| command (see |:make_makeprg|)
+	and the |:grep| command.
+	When it is empty, an internally generated temp file will be used.
+	When "##" is included, it is replaced by a number to make the name
+	unique.  This makes sure that the ":make" command doesn't overwrite an
+	existing file.
+	NOT used for the ":cf" command.  See 'errorfile' for that.
+	Environment variables are expanded |:set_env|.
+	See |option-backslash| about including spaces and backslashes.
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+					*'makeencoding'* *'menc'*
+'makeencoding' 'menc'	string	(default "")
+			global or local to buffer |global-local|
+	Encoding used for reading the output of external commands.  When empty,
+	encoding is not converted.
+	This is used for `:make`, `:lmake`, `:grep`, `:lgrep`, `:grepadd`,
+	`:lgrepadd`, `:cfile`, `:cgetfile`, `:caddfile`, `:lfile`, `:lgetfile`,
+	and `:laddfile`.
+
+	This would be mostly useful when you use MS-Windows and set 'encoding'
+	to "utf-8".  If |+iconv| is enabled and GNU libiconv is used, setting
+	'makeencoding' to "char" has the same effect as setting to the system
+	locale encoding.  Example: >
+		:set encoding=utf-8
+		:set makeencoding=char	" system locale is used
+<
+						*'makeprg'* *'mp'*
+'makeprg' 'mp'		string	(default "make", VMS: "MMS")
+			global or local to buffer |global-local|
+	Program to use for the ":make" command.  See |:make_makeprg|.
+	This option may contain '%' and '#' characters (see  |:_%| and |:_#|),
+	which are expanded to the current and alternate file name.  Use |::S|
+	to escape file names in case they contain special characters.
+	Environment variables are expanded |:set_env|.  See |option-backslash|
+	about including spaces and backslashes.
+	Note that a '|' must be escaped twice: once for ":set" and once for
+	the interpretation of a command.  When you use a filter called
+	"myfilter" do it like this: >
+	    :set makeprg=gmake\ \\\|\ myfilter
+<	The placeholder "$*" can be given (even multiple times) to specify
+	where the arguments will be included, for example: >
+	    :set makeprg=latex\ \\\\nonstopmode\ \\\\input\\{$*}
+<	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+						*'matchpairs'* *'mps'*
+'matchpairs' 'mps'	string	(default "(:),{:},[:]")
+			local to buffer
+	Characters that form pairs.  The |%| command jumps from one to the
+	other.
+	Only character pairs are allowed that are different, thus you cannot
+	jump between two double quotes.
+	The characters must be separated by a colon.
+	The pairs must be separated by a comma.  Example for including '<' and
+	'>' (for HTML): >
+		:set mps+=<:>
+
+<	A more exotic example, to jump between the '=' and ';' in an
+	assignment, useful for languages like C and Java: >
+		:au FileType c,cpp,java set mps+==:;
+
+<	For a more advanced way of using "%", see the matchit.vim plugin in
+	the $VIMRUNTIME/pack/dist/opt/matchit directory. |add-local-help|
+
+						*'matchtime'* *'mat'*
+'matchtime' 'mat'	number	(default 5)
+			global
+	Tenths of a second to show the matching paren, when 'showmatch' is
+	set.  Note that this is not in milliseconds, like other options that
+	set a time.  This is to be compatible with Nvi.
+
+						*'maxcombine'* *'mco'*
+'maxcombine' 'mco'	number (default 2)
+			global
+	The maximum number of combining characters supported for displaying.
+	Only used when 'encoding' is "utf-8".
+	The default is OK for most languages.  Hebrew may require 4.
+	Maximum value is 6.
+	Even when this option is set to 2 you can still edit text with more
+	combining characters, you just can't see them.  Use |g8| or |ga|.
+	See |mbyte-combining|.
+
+						*'maxfuncdepth'* *'mfd'*
+'maxfuncdepth' 'mfd'	number	(default 100)
+			global
+			{not available when compiled without the |+eval|
+			feature}
+	Maximum depth of function calls for user functions.  This normally
+	catches endless recursion.  When using a recursive function with
+	more depth, set 'maxfuncdepth' to a bigger number.  But this will use
+	more memory, there is the danger of failing when memory is exhausted.
+	Increasing this limit above 200 also changes the maximum for Ex
+	command recursion, see |E169|.
+	See also |:function|.
+
+						*'maxmapdepth'* *'mmd'* *E223*
+'maxmapdepth' 'mmd'	number	(default 1000)
+			global
+	Maximum number of times a mapping is done without resulting in a
+	character to be used.  This normally catches endless mappings, like
+	":map x y" with ":map y x".  It still does not catch ":map g wg",
+	because the 'w' is used before the next mapping is done.  See also
+	|key-mapping|.
+
+						*'maxmem'* *'mm'*
+'maxmem' 'mm'		number	(default between 256 to 5120 (system
+				 dependent) or half the amount of memory
+				 available)
+			global
+	Maximum amount of memory (in Kbyte) to use for one buffer.  When this
+	limit is reached allocating extra memory for a buffer will cause
+	other memory to be freed.
+	The maximum usable value is about 2000000.  Use this to work without a
+	limit.
+	The value is ignored when 'swapfile' is off.
+	Also see 'maxmemtot'.
+
+						*'maxmempattern'* *'mmp'*
+'maxmempattern' 'mmp'	number	(default 1000)
+			global
+	Maximum amount of memory (in Kbyte) to use for pattern matching.
+	The maximum value is about 2000000.  Use this to work without a limit.
+							*E363*
+	When Vim runs into the limit it gives an error message and mostly
+	behaves like CTRL-C was typed.
+	Running into the limit often means that the pattern is very
+	inefficient or too complex.  This may already happen with the pattern
+	"\(.\)*" on a very long line.  ".*" works much better.
+	Might also happen on redraw, when syntax rules try to match a complex
+	text structure.
+	Vim may run out of memory before hitting the 'maxmempattern' limit, in
+	which case you get an "Out of memory" error instead.
+
+						*'maxmemtot'* *'mmt'*
+'maxmemtot' 'mmt'	number	(default between 2048 and 10240 (system
+				 dependent) or half the amount of memory
+				 available)
+			global
+	Maximum amount of memory in Kbyte to use for all buffers together.
+	The maximum usable value is about 2000000 (2 Gbyte).  Use this to work
+	without a limit.
+	On 64 bit machines higher values might work.  But hey, do you really
+	need more than 2 Gbyte for text editing?  Keep in mind that text is
+	stored in the swap file, one can edit files > 2 Gbyte anyway.  We do
+	need the memory to store undo info.
+	Buffers with 'swapfile' off still count to the total amount of memory
+	used.
+	Also see 'maxmem'.
+
+						*'menuitems'* *'mis'*
+'menuitems' 'mis'	number	(default 25)
+			global
+			{not available when compiled without the |+menu|
+			feature}
+	Maximum number of items to use in a menu.  Used for menus that are
+	generated from a list of items, e.g., the Buffers menu.  Changing this
+	option has no direct effect, the menu must be refreshed first.
+
+						*'mkspellmem'* *'msm'*
+'mkspellmem' 'msm'	string	(default "460000,2000,500")
+			global
+			{not available when compiled without the |+syntax|
+			feature}
+	Parameters for |:mkspell|.  This tunes when to start compressing the
+	word tree.  Compression can be slow when there are many words, but
+	it's needed to avoid running out of memory.  The amount of memory used
+	per word depends very much on how similar the words are, that's why
+	this tuning is complicated.
+
+	There are three numbers, separated by commas:
+		{start},{inc},{added}
+
+	For most languages the uncompressed word tree fits in memory.  {start}
+	gives the amount of memory in Kbyte that can be used before any
+	compression is done.  It should be a bit smaller than the amount of
+	memory that is available to Vim.
+
+	When going over the {start} limit the {inc} number specifies the
+	amount of memory in Kbyte that can be allocated before another
+	compression is done.  A low number means compression is done after
+	less words are added, which is slow.  A high number means more memory
+	will be allocated.
+
+	After doing compression, {added} times 1024 words can be added before
+	the {inc} limit is ignored and compression is done when any extra
+	amount of memory is needed.  A low number means there is a smaller
+	chance of hitting the {inc} limit, less memory is used but it's
+	slower.
+
+	The languages for which these numbers are important are Italian and
+	Hungarian.  The default works for when you have about 512 Mbyte.  If
+	you have 1 Gbyte you could use: >
+		:set mkspellmem=900000,3000,800
+<	If you have less than 512 Mbyte |:mkspell| may fail for some
+	languages, no matter what you set 'mkspellmem' to.
+
+	This option cannot be set from a |modeline| or in the |sandbox|.
+
+				   *'modeline'* *'ml'* *'nomodeline'* *'noml'*
+'modeline' 'ml'		boolean	(Vim default: on (off for root),
+				 Vi default: off)
+			local to buffer
+	If 'modeline' is on 'modelines' gives the number of lines that is
+	checked for set commands.  If 'modeline' is off or 'modelines' is zero
+	no lines are checked.  See |modeline|.
+
+			   *'modelineexpr'* *'mle'* *'nomodelineexpr'* *'nomle'*
+'modelineexpr' 'mle'	boolean (default: off)
+			global
+	When on allow some options that are an expression to be set in the
+	modeline.  Check the option for whether it is affected by
+	'modelineexpr'.  Also see |modeline|.
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+						*'modelines'* *'mls'*
+'modelines' 'mls'	number	(default 5)
+			global
+	If 'modeline' is on 'modelines' gives the number of lines that is
+	checked for set commands.  If 'modeline' is off or 'modelines' is zero
+	no lines are checked.  See |modeline|.
+	NOTE: 'modeline' is set to the Vi default value when 'compatible' is
+	set and to the Vim default value when 'compatible' is reset.
+
+				*'modifiable'* *'ma'* *'nomodifiable'* *'noma'*
+				*E21*
+'modifiable' 'ma'	boolean	(default on)
+			local to buffer
+	When off the buffer contents cannot be changed.  The 'fileformat' and
+	'fileencoding' options also can't be changed.
+	Can be reset on startup with the |-M| command line argument.
+
+				*'modified'* *'mod'* *'nomodified'* *'nomod'*
+'modified' 'mod'	boolean	(default off)
+			local to buffer
+	When on, the buffer is considered to be modified.  This option is set
+	when:
+	1. A change was made to the text since it was last written.  Using the
+	   |undo| command to go back to the original text will reset the
+	   option.  But undoing changes that were made before writing the
+	   buffer will set the option again, since the text is different from
+	   when it was written.
+	2. 'fileformat' or 'fileencoding' is different from its original
+	   value.  The original value is set when the buffer is read or
+	   written.  A ":set nomodified" command also resets the original
+	   values to the current values and the 'modified' option will be
+	   reset.
+	   Similarly for 'eol' and 'bomb'.
+	This option is not set when a change is made to the buffer as the
+	result of a BufNewFile, BufRead/BufReadPost, BufWritePost,
+	FileAppendPost or VimLeave autocommand event.  See |gzip-example| for
+	an explanation.
+	When 'buftype' is "nowrite" or "nofile" this option may be set, but
+	will be ignored.
+	Note that the text may actually be the same, e.g. 'modified' is set
+	when using "rA" on an "A".
+
+						*'more'* *'nomore'*
+'more'			boolean	(Vim default: on, Vi default: off)
+			global
+	When on, listings pause when the whole screen is filled.  You will get
+	the |more-prompt|.  When this option is off there are no pauses, the
+	listing continues until finished.
+	NOTE: This option is set to the Vi default value when 'compatible' is
+	set and to the Vim default value when 'compatible' is reset.
+
+						*'mouse'*
+'mouse'			string	(default "", "a" for GUI and Win32,
+					set to "a" or "nvi" in |defaults.vim|)
+			global
+	Enable the use of the mouse.  Works for most terminals (xterm, Win32
+	|win32-mouse|, QNX pterm, *BSD console with sysmouse and Linux console
+	with gpm).  For using the mouse in the GUI, see |gui-mouse|.  The
+	mouse can be enabled for different modes:
+		n	Normal mode and Terminal modes
+		v	Visual mode
+		i	Insert mode
+		c	Command-line mode
+		h	all previous modes when editing a help file
+		a	all previous modes
+		r	for |hit-enter| and |more-prompt| prompt
+	Normally you would enable the mouse in all five modes with: >
+		:set mouse=a
+<	If your terminal can't overrule the mouse events going to the
+	application, use: >
+		:set mouse=nvi
+<	Then you can press ":", select text for the system, and press Esc to go
+	back to Vim using the mouse events.
+	In |defaults.vim| "nvi" is used if the 'term' option is not matching
+	"xterm".
+
+	When the mouse is not enabled, the GUI will still use the mouse for
+	modeless selection.  This doesn't move the text cursor.
+
+	See |mouse-using|.  Also see |'clipboard'|.
+
+	Note: When enabling the mouse in a terminal, copy/paste will use the
+	"* register if there is access to an X-server.  The xterm handling of
+	the mouse buttons can still be used by keeping the shift key pressed.
+	Also see the 'clipboard' option.
+
+			*'mousefocus'* *'mousef'* *'nomousefocus'* *'nomousef'*
+'mousefocus' 'mousef'	boolean	(default off)
+			global
+			{only works in the GUI}
+	The window that the mouse pointer is on is automatically activated.
+	When changing the window layout or window focus in another way, the
+	mouse pointer is moved to the window with keyboard focus.  Off is the
+	default because it makes using the pull down menus a little goofy, as
+	a pointer transit may activate a window unintentionally.
+	MS-Windows: Also see 'scrollfocus' for what window is scrolled when
+	using the mouse scroll wheel.
+
+			*'mousehide'* *'mh'* *'nomousehide'* *'nomh'*
+'mousehide' 'mh'	boolean	(default on)
+			global
+			{only works in the GUI}
+	When on, the mouse pointer is hidden when characters are typed.
+	The mouse pointer is restored when the mouse is moved.
+
+						*'mousemodel'* *'mousem'*
+'mousemodel' 'mousem'	string	(default "extend", "popup" for Win32)
+			global
+	Sets the model to use for the mouse.  The name mostly specifies what
+	the right mouse button is used for:
+	   extend	Right mouse button extends a selection.  This works
+			like in an xterm.
+	   popup	Right mouse button pops up a menu.  The shifted left
+			mouse button extends a selection.  This works like
+			with Microsoft Windows.
+	   popup_setpos Like "popup", but the cursor will be moved to the
+			position where the mouse was clicked, and thus the
+			selected operation will act upon the clicked object.
+			If clicking inside a selection, that selection will
+			be acted upon, i.e. no cursor move.  This implies of
+			course, that right clicking outside a selection will
+			end Visual mode.
+	Overview of what button does what for each model:
+	mouse		    extend		popup(_setpos) ~
+	left click	    place cursor	place cursor
+	left drag	    start selection	start selection
+	shift-left	    search word		extend selection
+	right click	    extend selection	popup menu (place cursor)
+	right drag	    extend selection	-
+	middle click	    paste		paste
+
+	In the "popup" model the right mouse button produces a pop-up menu.
+	You need to define this first, see |popup-menu|.
+
+	Note that you can further refine the meaning of buttons with mappings.
+	See |gui-mouse-mapping|.  But mappings are NOT used for modeless
+	selection (because that's handled in the GUI code directly).
+
+	The 'mousemodel' option is set by the |:behave| command.
+
+	      *'mousemoveevent'* *'mousemev'* *'nomousemoveevent'* *'nomousemev'*
+'mousemoveevent' 'mousemev'  boolean	(default off)
+			global
+			{only works in the GUI}
+	When on, mouse move events are delivered to the input queue and are
+	available for mapping. The default, off, avoids the mouse movement
+	overhead except when needed. See |gui-mouse-mapping|.
+	Warning: Setting this option can make pending mappings to be aborted
+	when the mouse is moved.
+	Currently only works in the GUI, may be made to work in a terminal
+	later.
+
+					*'mouseshape'* *'mouses'* *E547*
+'mouseshape' 'mouses'	string	(default "i-r:beam,s:updown,sd:udsizing,
+					vs:leftright,vd:lrsizing,m:no,
+					ml:up-arrow,v:rightup-arrow")
+			global
+			{only available when compiled with the |+mouseshape|
+			feature}
+	This option tells Vim what the mouse pointer should look like in
+	different modes.  The option is a comma-separated list of parts, much
+	like used for 'guicursor'.  Each part consist of a mode/location-list
+	and an argument-list:
+		mode-list:shape,mode-list:shape,..
+	The mode-list is a dash separated list of these modes/locations:
+			In a normal window: ~
+		n	Normal mode
+		v	Visual mode
+		ve	Visual mode with 'selection' "exclusive" (same as 'v',
+			if not specified)
+		o	Operator-pending mode
+		i	Insert mode
+		r	Replace mode
+
+			Others: ~
+		c	appending to the command-line
+		ci	inserting in the command-line
+		cr	replacing in the command-line
+		m	at the 'Hit ENTER' or 'More' prompts
+		ml	idem, but cursor in the last line
+		e	any mode, pointer below last window
+		s	any mode, pointer on a status line
+		sd	any mode, while dragging a status line
+		vs	any mode, pointer on a vertical separator line
+		vd	any mode, while dragging a vertical separator line
+		a	everywhere
+
+	The shape is one of the following:
+	avail	name		looks like ~
+	w x	arrow		Normal mouse pointer
+	w x	blank		no pointer at all (use with care!)
+	w x	beam		I-beam
+	w x	updown		up-down sizing arrows
+	w x	leftright	left-right sizing arrows
+	w x	busy		The system's usual busy pointer
+	w x	no		The system's usual 'no input' pointer
+	  x	udsizing	indicates up-down resizing
+	  x	lrsizing	indicates left-right resizing
+	  x	crosshair	like a big thin +
+	  x	hand1		black hand
+	  x	hand2		white hand
+	  x	pencil		what you write with
+	  x	question	big ?
+	  x	rightup-arrow	arrow pointing right-up
+	w x	up-arrow	arrow pointing up
+	  x	<number>	any X11 pointer number (see X11/cursorfont.h)
+
+	The "avail" column contains a 'w' if the shape is available for Win32,
+	x for X11.
+	Any modes not specified or shapes not available use the normal mouse
+	pointer.
+
+	Example: >
+		:set mouseshape=s:udsizing,m:no
+<	will make the mouse turn to a sizing arrow over the status lines and
+	indicate no input when the hit-enter prompt is displayed (since
+	clicking the mouse has no effect in this state.)
+
+						*'mousetime'* *'mouset'*
+'mousetime' 'mouset'	number	(default 500)
+			global
+	Only for GUI, Win32 and Unix with xterm.  Defines the maximum
+	time in msec between two mouse clicks for the second click to be
+	recognized as a multi click.
+
+						*'mzschemedll'*
+'mzschemedll'		string	(default depends on the build)
+			global
+			{only available when compiled with the |+mzscheme/dyn|
+			feature}
+	Specifies the name of the MzScheme shared library. The default is
+	DYNAMIC_MZSCH_DLL which was specified at compile time.
+	Environment variables are expanded |:set_env|.
+	The value must be set in the |vimrc| script or earlier.  In the
+	startup, before the |load-plugins| step.
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+						*'mzschemegcdll'*
+'mzschemegcdll'		string	(default depends on the build)
+			global
+			{only available when compiled with the |+mzscheme/dyn|
+			feature}
+	Specifies the name of the MzScheme GC shared library. The default is
+	DYNAMIC_MZGC_DLL which was specified at compile time.
+	The value can be equal to 'mzschemedll' if it includes the GC code.
+	Environment variables are expanded |:set_env|.
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+						    *'mzquantum'* *'mzq'*
+'mzquantum' 'mzq'	number	(default 100)
+			global
+			{not available when compiled without the |+mzscheme|
+			feature}
+	The number of milliseconds between polls for MzScheme threads.
+	Negative or zero value means no thread scheduling.
+	NOTE: This option is set to the Vim default value when 'compatible'
+	is reset.
+
+							*'nrformats'* *'nf'*
+'nrformats' 'nf'	string	(default "bin,octal,hex",
+					   set to "bin,hex" in |defaults.vim|)
+			local to buffer
+	This defines what bases Vim will consider for numbers when using the
+	CTRL-A and CTRL-X commands for adding to and subtracting from a number
+	respectively; see |CTRL-A| for more info on these commands.
+	alpha	If included, single alphabetical characters will be
+		incremented or decremented.  This is useful for a list with a
+		letter index a), b), etc.		*octal-nrformats*
+	octal	If included, numbers that start with a zero will be considered
+		to be octal.  Example: Using CTRL-A on "007" results in "010".
+	hex	If included, numbers starting with "0x" or "0X" will be
+		considered to be hexadecimal.  Example: Using CTRL-X on
+		"0x100" results in "0x0ff".
+	bin	If included, numbers starting with "0b" or "0B" will be
+		considered to be binary.  Example: Using CTRL-X on
+		"0b1000" subtracts one, resulting in "0b0111".
+	unsigned    If included, numbers are recognized as unsigned. Thus a
+		leading dash or negative sign won't be considered as part of
+		the number.  Examples:
+		    Using CTRL-X on "2020" in "9-2020" results in "9-2019"
+		    (without "unsigned" it would become "9-2021").
+		    Using CTRL-A on "2020" in "9-2020" results in "9-2021"
+		    (without "unsigned" it would become "9-2019").
+		    Using CTRL-X on "0" or CTRL-A on "18446744073709551615"
+		    (2^64 - 1) has no effect, overflow is prevented.
+	Numbers which simply begin with a digit in the range 1-9 are always
+	considered decimal.  This also happens for numbers that are not
+	recognized as octal or hex.
+
+				*'number'* *'nu'* *'nonumber'* *'nonu'*
+'number' 'nu'		boolean	(default off)
+			local to window
+	Print the line number in front of each line.  When the 'n' option is
+	excluded from 'cpoptions' a wrapped line will not use the column of
+	line numbers (this is the default when 'compatible' isn't set).
+	The 'numberwidth' option can be used to set the room used for the line
+	number.
+	When a long, wrapped line doesn't start with the first character, '-'
+	characters are put before the number.
+	For highlighting see |hl-LineNr|, and |hl-CursorLineNr|, and the
+	|:sign-define| "numhl" argument.
+						*number_relativenumber*
+	The 'relativenumber' option changes the displayed number to be
+	relative to the cursor.  Together with 'number' there are these
+	four combinations (cursor in line 3):
+
+		'nonu'          'nu'            'nonu'          'nu'
+		'nornu'         'nornu'         'rnu'           'rnu'
+
+	    |apple          |  1 apple      |  2 apple      |  2 apple
+	    |pear           |  2 pear       |  1 pear       |  1 pear
+	    |nobody         |  3 nobody     |  0 nobody     |3   nobody
+	    |there          |  4 there      |  1 there      |  1 there
+
+						*'numberwidth'* *'nuw'*
+'numberwidth' 'nuw'	number	(Vim default: 4  Vi default: 8)
+			local to window
+			{only available when compiled with the |+linebreak|
+			feature}
+	Minimal number of columns to use for the line number.  Only relevant
+	when the 'number' or 'relativenumber' option is set or printing lines
+	with a line number. Since one space is always between the number and
+	the text, there is one less character for the number itself.
+	The value is the minimum width.  A bigger width is used when needed to
+	fit the highest line number in the buffer respectively the number of
+	rows in the window, depending on whether 'number' or 'relativenumber'
+	is set. Thus with the Vim default of 4 there is room for a line number
+	up to 999. When the buffer has 1000 lines five columns will be used.
+	The minimum value is 1, the maximum value is 20.
+	NOTE: This option is set to the Vi default value when 'compatible' is
+	set and to the Vim default value when 'compatible' is reset.
+
+						*'omnifunc'* *'ofu'*
+'omnifunc' 'ofu'	string	(default: empty)
+			local to buffer
+			{not available when compiled without the |+eval|
+			feature}
+	This option specifies a function to be used for Insert mode omni
+	completion with CTRL-X CTRL-O. |i_CTRL-X_CTRL-O|
+	See |complete-functions| for an explanation of how the function is
+	invoked and what it should return.  The value can be the name of a
+	function, a |lambda| or a |Funcref|. See |option-value-function| for
+	more information.
+	This option is usually set by a filetype plugin:
+	|:filetype-plugin-on|
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+
+			    *'opendevice'* *'odev'* *'noopendevice'* *'noodev'*
+'opendevice' 'odev'	boolean	(default off)
+			global
+			{only for MS-Windows}  *E796*
+	Enable reading and writing from devices.  This may get Vim stuck on a
+	device that can be opened but doesn't actually do the I/O.  Therefore
+	it is off by default.
+	Note that on MS-Windows editing "aux.h", "lpt1.txt" and the like also
+	result in editing a device.
+
+
+						*'operatorfunc'* *'opfunc'*
+'operatorfunc' 'opfunc'	string	(default: empty)
+			global
+	This option specifies a function to be called by the |g@| operator.
+	See |:map-operator| for more info and an example.  The value can be
+	the name of a function, a |lambda| or a |Funcref|. See
+	|option-value-function| for more information.
+
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+
+					*'osfiletype'* *'oft'*
+'osfiletype' 'oft'	string (default: "")
+			local to buffer
+	This option was supported on RISC OS, which has been removed.
+
+
+				*'packpath'* *'pp'*
+'packpath' 'pp'		string	(default: see 'runtimepath')
+	Directories used to find packages.  See |packages|.
+
+
+						*'paragraphs'* *'para'*
+'paragraphs' 'para'	string	(default "IPLPPPQPP TPHPLIPpLpItpplpipbp")
+			global
+	Specifies the nroff macros that separate paragraphs.  These are pairs
+	of two letters (see |object-motions|).
+
+						*'paste'* *'nopaste'*
+'paste'			boolean	(default off)
+			global
+	Put Vim in Paste mode.  This is useful if you want to cut or copy
+	some text from one window and paste it in Vim.  This will avoid
+	unexpected effects.
+	Setting this option is useful when using Vim in a terminal, where Vim
+	cannot distinguish between typed text and pasted text.  In the GUI, Vim
+	knows about pasting and will mostly do the right thing without 'paste'
+	being set.  The same is true for a terminal where Vim handles the
+	mouse clicks itself.
+	This option is reset when starting the GUI.  Thus if you set it in
+	your .vimrc it will work in a terminal, but not in the GUI.  Setting
+	'paste' in the GUI has side effects: e.g., the Paste toolbar button
+	will no longer work in Insert mode, because it uses a mapping.
+	When the 'paste' option is switched on (also when it was already on):
+		- mapping in Insert mode and Command-line mode is disabled
+		- abbreviations are disabled
+		- 'autoindent' is reset
+		- 'expandtab' is reset
+		- 'hkmap' is reset
+		- 'revins' is reset
+		- 'ruler' is reset
+		- 'showmatch' is reset
+		- 'smarttab' is reset
+		- 'softtabstop' is set to 0
+		- 'textwidth' is set to 0
+		- 'wrapmargin' is set to 0
+		- 'varsofttabstop' is made empty
+	These options keep their value, but their effect is disabled:
+		- 'cindent'
+		- 'formatoptions' is used like it is empty
+		- 'indentexpr'
+		- 'lisp'
+		- 'smartindent'
+	NOTE: When you start editing another file while the 'paste' option is
+	on, settings from the modelines or autocommands may change the
+	settings again, causing trouble when pasting text.  You might want to
+	set the 'paste' option again.
+	When the 'paste' option is reset the mentioned options are restored to
+	the value before the moment 'paste' was switched from off to on.
+	Resetting 'paste' before ever setting it does not have any effect.
+	Since mapping doesn't work while 'paste' is active, you need to use
+	the 'pastetoggle' option to toggle the 'paste' option with some key.
+
+						*'pastetoggle'* *'pt'*
+'pastetoggle' 'pt'	string	(default "")
+			global
+	When non-empty, specifies the key sequence that toggles the 'paste'
+	option.  This is like specifying a mapping: >
+	    :map {keys} :set invpaste<CR>
+<	Where {keys} is the value of 'pastetoggle'.
+	The difference is that it will work even when 'paste' is set.
+	'pastetoggle' works in Insert mode and Normal mode, but not in
+	Command-line mode.
+	Mappings are checked first, thus overrule 'pastetoggle'.  However,
+	when 'paste' is on mappings are ignored in Insert mode, thus you can do
+	this: >
+	    :map <F10> :set paste<CR>
+	    :map <F11> :set nopaste<CR>
+	    :imap <F10> <C-O>:set paste<CR>
+	    :imap <F11> <nop>
+	    :set pastetoggle=<F11>
+<	This will make <F10> start paste mode and <F11> stop paste mode.
+	Note that typing <F10> in paste mode inserts "<F10>", since in paste
+	mode everything is inserted literally, except the 'pastetoggle' key
+	sequence.
+	When the value has several bytes 'ttimeoutlen' applies.
+
+						*'pex'* *'patchexpr'*
+'patchexpr' 'pex'	string	(default "")
+			global
+			{not available when compiled without the |+diff|
+			feature}
+	Expression which is evaluated to apply a patch to a file and generate
+	the resulting new version of the file.  See |diff-patchexpr|.
+
+					*'patchmode'* *'pm'* *E205* *E206*
+'patchmode' 'pm'	string	(default "")
+			global
+	When non-empty the oldest version of a file is kept.  This can be used
+	to keep the original version of a file if you are changing files in a
+	source distribution.  Only the first time that a file is written a
+	copy of the original file will be kept.  The name of the copy is the
+	name of the original file with the string in the 'patchmode' option
+	appended.  This option should start with a dot.  Use a string like
+	".orig" or ".org".  'backupdir' must not be empty for this to work
+	(Detail: The backup file is renamed to the patchmode file after the
+	new file has been successfully written, that's why it must be possible
+	to write a backup file).  If there was no file to be backed up, an
+	empty file is created.
+	When the 'backupskip' pattern matches, a patchmode file is not made.
+	Using 'patchmode' for compressed files appends the extension at the
+	end (e.g., "file.gz.orig"), thus the resulting name isn't always
+	recognized as a compressed file.
+	Only normal file name characters can be used, "/\*?[|<>" are illegal.
+
+				*'path'* *'pa'* *E343* *E345* *E347* *E854*
+'path' 'pa'		string	(default on Unix: ".,/usr/include,,"
+				   other systems: ".,,")
+			global or local to buffer |global-local|
+	This is a list of directories which will be searched when using the
+	|gf|, [f, ]f, ^Wf, |:find|, |:sfind|, |:tabfind| and other commands,
+	provided that the file being searched for has a relative path (not
+	starting with "/", "./" or "../").  The directories in the 'path'
+	option may be relative or absolute.
+	- Use commas to separate directory names: >
+		:set path=.,/usr/local/include,/usr/include
+<	- Spaces can also be used to separate directory names (for backwards
+	  compatibility with version 3.0).  To have a space in a directory
+	  name, precede it with an extra backslash, and escape the space: >
+		:set path=.,/dir/with\\\ space
+<	- To include a comma in a directory name precede it with an extra
+	  backslash: >
+		:set path=.,/dir/with\\,comma
+<	- To search relative to the directory of the current file, use: >
+		:set path=.
+<	- To search in the current directory use an empty string between two
+	  commas: >
+		:set path=,,
+<	- A directory name may end in a ':' or '/'.
+	- Environment variables are expanded |:set_env|.
+	- When using |netrw.vim| URLs can be used.  For example, adding
+	  "http://www.vim.org" will make ":find index.html" work.
+	- Search upwards and downwards in a directory tree using "*", "**" and
+	  ";".  See |file-searching| for info and syntax.
+	- Careful with '\' characters, type two to get one in the option: >
+		:set path=.,c:\\include
+<	  Or just use '/' instead: >
+		:set path=.,c:/include
+<	Don't forget "." or files won't even be found in the same directory as
+	the file!
+	The maximum length is limited.  How much depends on the system, mostly
+	it is something like 256 or 1024 characters.
+	You can check if all the include files are found, using the value of
+	'path', see |:checkpath|.
+	The use of |:set+=| and |:set-=| is preferred when adding or removing
+	directories from the list.  This avoids problems when a future version
+	uses another default.  To remove the current directory use: >
+		:set path-=
+<	To add the current directory use: >
+		:set path+=
+<	To use an environment variable, you probably need to replace the
+	separator.  Here is an example to append $INCL, in which directory
+	names are separated with a semi-colon: >
+		:let &path = &path .. "," .. substitute($INCL, ';', ',', 'g')
+<	Replace the ';' with a ':' or whatever separator is used.  Note that
+	this doesn't work when $INCL contains a comma or white space.
+
+						*'perldll'*
+'perldll'		string	(default depends on the build)
+			global
+			{only available when compiled with the |+perl/dyn|
+			feature}
+	Specifies the name of the Perl shared library. The default is
+	DYNAMIC_PERL_DLL, which was specified at compile time.
+	Environment variables are expanded |:set_env|.
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+			*'preserveindent'* *'pi'* *'nopreserveindent'* *'nopi'*
+'preserveindent' 'pi'	boolean	(default off)
+			local to buffer
+	When changing the indent of the current line, preserve as much of the
+	indent structure as possible.  Normally the indent is replaced by a
+	series of tabs followed by spaces as required (unless |'expandtab'| is
+	enabled, in which case only spaces are used).  Enabling this option
+	means the indent will preserve as many existing characters as possible
+	for indenting, and only add additional tabs or spaces as required.
+	'expandtab' does not apply to the preserved white space, a Tab remains
+	a Tab.
+	NOTE: When using ">>" multiple times the resulting indent is a mix of
+	tabs and spaces.  You might not like this.
+	NOTE: This option is reset when 'compatible' is set.
+	Also see 'copyindent'.
+	Use |:retab| to clean up white space.
+
+					*'previewheight'* *'pvh'*
+'previewheight' 'pvh'	number (default 12)
+			global
+			{not available when compiled without the |+quickfix|
+			feature}
+	Default height for a preview window.  Used for |:ptag| and associated
+	commands.  Used for |CTRL-W_}| when no count is given.  Not used when
+	'previewpopup' is set.
+
+					*'previewpopup'* *'pvp'*
+'previewpopup' 'pvp'	string (default empty)
+			global
+			{not available when compiled without the |+textprop|
+			or |+quickfix| feature}
+	When not empty a popup window is used for commands that would open a
+	preview window.  See |preview-popup|.
+	Not used for the insert completion info, add "popup" to
+	'completeopt' for that.
+
+					*'previewwindow'* *'nopreviewwindow'*
+					*'pvw'* *'nopvw'* *E590*
+'previewwindow' 'pvw'	boolean (default off)
+			local to window
+			{not available when compiled without the |+quickfix|
+			feature}
+	Identifies the preview window.  Only one window can have this option
+	set.  It's normally not set directly, but by using one of the commands
+	|:ptag|, |:pedit|, etc.
+
+						*'printdevice'* *'pdev'*
+'printdevice' 'pdev'	string	(default empty)
+			global
+			{only available when compiled with the |+printer|

+						*'pythonhome'*
+'pythonhome'		string	(default "")
+			global
+			{only available when compiled with the |+python/dyn|
+			feature}
+	Specifies the name of the Python 2.x home directory. When 'pythonhome'
+	and the PYTHONHOME environment variable are not set, PYTHON_HOME,
+	which was specified at compile time, will be used for the Python 2.x
+	home directory.
+	Environment variables are expanded |:set_env|.
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+						*'pythonthreedll'*
+'pythonthreedll'	string	(default depends on the build)
+			global
+			{only available when compiled with the |+python3/dyn|
+			feature}
+	Specifies the name of the Python 3 shared library. The default is
+	DYNAMIC_PYTHON3_DLL, which was specified at compile time.
+	Environment variables are expanded |:set_env|.
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+						*'pythonthreehome'*
+'pythonthreehome'	string	(default "")
+			global
+			{only available when compiled with the |+python3/dyn|
+			feature}
+	Specifies the name of the Python 3 home directory. When
+	'pythonthreehome' and the PYTHONHOME environment variable are not set,
+	PYTHON3_HOME, which was specified at compile time, will be used for
+	the Python 3 home directory.
+	Environment variables are expanded |:set_env|.
+	This option cannot be set from a |modeline| or in the |sandbox|, for

+
+						*'pyxversion'* *'pyx'*
+'pyxversion' 'pyx'	number	(default depends on the build)
+			global
+			{only available when compiled with the |+python| or
+			the |+python3| feature}
+	Specifies the python version used for pyx* functions and commands
+	|python_x|.  The default value is as follows:
+
+		Compiled with		     Default ~
+		|+python| and |+python3|	0
+		only |+python|			2
+		only |+python3|			3
+
+	Available values are 0, 2 and 3.
+	If 'pyxversion' is 0, it is set to 2 or 3 after the first execution of
+	any python2/3 commands or functions.  E.g. `:py` sets to 2, and `:py3`
+	sets to 3. `:pyx` sets it to 3 if Python 3 is available, otherwise sets
+	to 2 if Python 2 is available.
+	See also: |has-pythonx|
+
+	If Vim is compiled with only |+python| or |+python3| setting
+	'pyxversion' has no effect.  The pyx* functions and commands are
+	always the same as the compiled version.
+
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+						*'quickfixtextfunc'* *'qftf'*
+'quickfixtextfunc' 'qftf'	string (default "")
+			global
+			{only available when compiled with the |+quickfix|
+			feature}
+	This option specifies a function to be used to get the text to display
+	in the quickfix and location list windows.  This can be used to
+	customize the information displayed in the quickfix or location window
+	for each entry in the corresponding quickfix or location list.  See
+	|quickfix-window-function| for an explanation of how to write the
+	function and an example.  The value can be the name of a function, a
+	|lambda| or a |Funcref|. See |option-value-function| for more
+	information.
+
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+						*'quoteescape'* *'qe'*
+'quoteescape' 'qe'	string	(default "\")
+			local to buffer
+	The characters that are used to escape quotes in a string.  Used for
+	objects like a', a" and a` |a'|.
+	When one of the characters in this option is found inside a string,
+	the following character will be skipped.  The default value makes the
+	text "foo\"bar\\" considered to be one string.
+
+				   *'readonly'* *'ro'* *'noreadonly'* *'noro'*
+'readonly' 'ro'		boolean	(default off)
+			local to buffer
+	If on, writes fail unless you use a '!'.  Protects you from
+	accidentally overwriting a file.  Default on when Vim is started
+	in read-only mode ("vim -R") or when the executable is called "view".
+	When using ":w!" the 'readonly' option is reset for the current
+	buffer, unless the 'Z' flag is in 'cpoptions'.
+	When using the ":view" command the 'readonly' option is set for the
+	newly edited buffer.
+	See 'modifiable' for disallowing changes to the buffer.
+
+						*'redrawtime'* *'rdt'*
+'redrawtime' 'rdt'	number	(default 2000)
+			global
+			{only available when compiled with the |+reltime|
+			feature}
+	The time in milliseconds for redrawing the display.  This applies to
+	searching for patterns for 'hlsearch', |:match| highlighting and syntax
+	highlighting.
+	When redrawing takes more than this many milliseconds no further
+	matches will be highlighted.
+	For syntax highlighting the time applies per window.  When over the
+	limit syntax highlighting is disabled until |CTRL-L| is used.
+	This is used to avoid that Vim hangs when using a very complicated
+	pattern.
+
+						*'regexpengine'* *'re'*
+'regexpengine' 're'	number	(default 0)
+			global
+	This selects the default regexp engine. |two-engines|
+	The possible values are:
+		0	automatic selection
+		1	old engine
+		2	NFA engine
+	Note that when using the NFA engine and the pattern contains something
+	that is not supported the pattern will not match.  This is only useful
+	for debugging the regexp engine.
+	Using automatic selection enables Vim to switch the engine, if the
+	default engine becomes too costly.  E.g., when the NFA engine uses too
+	many states.  This should prevent Vim from hanging on a combination of
+	a complex pattern with long text.
+
+		*'relativenumber'* *'rnu'* *'norelativenumber'* *'nornu'*
+'relativenumber' 'rnu'	boolean	(default off)
+			local to window
+	Show the line number relative to the line with the cursor in front of
+	each line. Relative line numbers help you use the |count| you can
+	precede some vertical motion commands (e.g. j k + -) with, without
+	having to calculate it yourself. Especially useful in combination with
+	other commands (e.g. y d c < > gq gw =).
+	When the 'n' option is excluded from 'cpoptions' a wrapped
+	line will not use the column of line numbers (this is the default when
+	'compatible' isn't set).
+	The 'numberwidth' option can be used to set the room used for the line
+	number.
+	When a long, wrapped line doesn't start with the first character, '-'
+	characters are put before the number.
+	See |hl-LineNr|  and |hl-CursorLineNr| for the highlighting used for
+	the number.
+
+	The number in front of the cursor line also depends on the value of
+	'number', see |number_relativenumber| for all combinations of the two
+	options.
+
+						*'remap'* *'noremap'*
+'remap'			boolean	(default on)
+			global
+	Allows for mappings to work recursively.  If you do not want this for
+	a single entry, use the :noremap[!] command.
+	NOTE: To avoid portability problems with Vim scripts, always keep
+	this option at the default "on".  Only switch it off when working with
+	old Vi scripts.
+
+                                               *'renderoptions'* *'rop'*
+'renderoptions' 'rop'	string  (default: empty)
+			global
+			{only available when compiled with GUI and DIRECTX on
+			MS-Windows}
+	Select a text renderer and set its options.  The options depend on the

+
+		  - If your font includes non-colored emoji already, it will

+	Other render types are currently not supported.
+
+						*'report'*
+'report'		number	(default 2)
+			global
+	Threshold for reporting number of lines changed.  When the number of
+	changed lines is more than 'report' a message will be given for most
+	":" commands.  If you want it always, set 'report' to 0.
+	For the ":substitute" command the number of substitutions is used
+	instead of the number of lines.
+
+			 *'restorescreen'* *'rs'* *'norestorescreen'* *'nors'*
+'restorescreen' 'rs'	boolean	(default on)
+			global
+			{only in MS-Windows console version}
+	When set, the screen contents is restored when exiting Vim.  This also
+	happens when executing external commands.
+
+	For non-Windows Vim: You can set or reset the 't_ti' and 't_te'
+	options in your .vimrc.  To disable restoring:
+		set t_ti= t_te=
+	To enable restoring (for an xterm):

+'revins' 'ri'		boolean	(default off)
+			global
+			{only available when compiled with the |+rightleft|
+			feature}
+	Inserting characters in Insert mode will work backwards.  See "typing
+	backwards" |ins-reverse|.  This option can be toggled with the CTRL-_
+	command in Insert mode, when 'allowrevins' is set.
+	NOTE: This option is reset when 'compatible' is set.
+	This option is reset when 'paste' is set and restored when 'paste' is
+	reset.
+
+				 *'rightleft'* *'rl'* *'norightleft'* *'norl'*
+'rightleft' 'rl'	boolean	(default off)
+			local to window
+			{only available when compiled with the |+rightleft|
+			feature}
+	When on, display orientation becomes right-to-left, i.e., characters
+	that are stored in the file appear from the right to the left.
+	Using this option, it is possible to edit files for languages that
+	are written from the right to the left such as Hebrew and Arabic.
+	This option is per window, so it is possible to edit mixed files
+	simultaneously, or to view the same file in both ways (this is
+	useful whenever you have a mixed text file with both right-to-left
+	and left-to-right strings so that both sets are displayed properly
+	in different windows).  Also see |rileft.txt|.
+
+			*'rightleftcmd'* *'rlc'*
+'rightleftcmd' 'rlc'	string	(default "search")
+			local to window

+			feature}
+	Each word in this option enables the command line editing to work in
+	right-to-left mode for a group of commands:
+
+		search		"/" and "?" commands
+
+	This is useful for languages such as Hebrew, Arabic and Farsi.
+	The 'rightleft' option must be set for 'rightleftcmd' to take effect.
+
+						*'rubydll'*
+'rubydll'		string	(default: depends on the build)
+			global
+			{only available when compiled with the |+ruby/dyn|
+			feature}
+	Specifies the name of the Ruby shared library. The default is
+	DYNAMIC_RUBY_DLL, which was specified at compile time.
+	Environment variables are expanded |:set_env|.
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+					 *'ruler'* *'ru'* *'noruler'* *'noru'*
+'ruler' 'ru'		boolean	(default off, set in |defaults.vim|)
+			global
+	Show the line and column number of the cursor position, separated by a
+	comma.  When there is room, the relative position of the displayed
+	text in the file is shown on the far right:
+		Top	first line is visible
+		Bot	last line is visible
+		All	first and last line are visible
+		45%	relative position in the file
+	If 'rulerformat' is set, it will determine the contents of the ruler.
+	Each window has its own ruler.  If a window has a status line, the
+	ruler is shown there.  Otherwise it is shown in the last line of the
+	screen.  If the statusline is given by 'statusline' (i.e. not empty),
+	this option takes precedence over 'ruler' and 'rulerformat'.
+	If the number of characters displayed is different from the number of
+	bytes in the text (e.g., for a TAB or a multibyte character), both
+	the text column (byte number) and the screen column are shown,
+	separated with a dash.
+	For an empty line "0-1" is shown.
+	For an empty buffer the line number will also be zero: "0,0-1".
+	This option is reset when 'paste' is set and restored when 'paste' is
+	reset.
+	If you don't want to see the ruler all the time but want to know where
+	you are, use "g CTRL-G" |g_CTRL-G|.
+	NOTE: This option is reset when 'compatible' is set.
+
+						*'rulerformat'* *'ruf'*
+'rulerformat' 'ruf'	string	(default empty)
+			global
+			{not available when compiled without the |+statusline|
+			feature}
+	When this option is not empty, it determines the content of the ruler
+	string, as displayed for the 'ruler' option.
+	The format of this option is like that of 'statusline'.
+	This option cannot be set in a modeline when 'modelineexpr' is off.
+
+	The default ruler width is 17 characters.  To make the ruler 15
+	characters wide, put "%15(" at the start and "%)" at the end.
+	Example: >
+		:set rulerformat=%15(%c%V\ %p%%%)

+
+	And any other file searched for with the |:runtime| command.
+
+	The defaults for most systems are setup to search five locations:
+	1. In your home directory, for your personal preferences.
+	2. In a system-wide Vim directory, for preferences from the system
+	   administrator.
+	3. In $VIMRUNTIME, for files distributed with Vim.
+							*after-directory*
+	4. In the "after" directory in the system-wide Vim directory.  This is
+	   for the system administrator to overrule or add to the distributed
+	   defaults (rarely needed)
+	5. In the "after" directory in your home directory.  This is for
+	   personal preferences to overrule or add to the distributed defaults
+	   or system-wide settings (rarely needed).
+
+	More entries are added when using |packages|.  If it gets very long
+	then `:set rtp` will be truncated, use `:echo &rtp` to see the full
+	string.
+
+	Note that, unlike 'path', no wildcards like "**" are allowed.  Normal
+	wildcards are allowed, but can significantly slow down searching for
+	runtime files.  For speed, use as few items as possible and avoid
+	wildcards.
+	See |:runtime|.
+	Example: >
+		:set runtimepath=~/vimruntime,/mygroup/vim,$VIMRUNTIME
+<	This will use the directory "~/vimruntime" first (containing your
+	personal Vim runtime files), then "/mygroup/vim" (shared between a
+	group of people) and finally "$VIMRUNTIME" (the distributed runtime
+	files).
+	You probably should always include $VIMRUNTIME somewhere, to use the
+	distributed runtime files.  You can put a directory before $VIMRUNTIME
+	to find files which replace a distributed runtime files.  You can put
+	a directory after $VIMRUNTIME to find files which add to distributed
+	runtime files.
+	When Vim is started with |--clean| the home directory entries are not
+	included.
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+						*'scroll'* *'scr'*
+'scroll' 'scr'		number	(default: half the window height)
+			local to window
+	Number of lines to scroll with CTRL-U and CTRL-D commands.  Will be
+	set to half the number of lines in the window when the window size
+	changes.  This may happen when enabling the |status-line| or
+	'tabline' option after setting the 'scroll' option.
+	If you give a count to the CTRL-U or CTRL-D command it will
+	be used as the new value for 'scroll'.  Reset to half the window
+	height with ":set scroll=0".
+
+			*'scrollbind'* *'scb'* *'noscrollbind'* *'noscb'*
+'scrollbind' 'scb'	boolean  (default off)
+			local to window
+	See also |scroll-binding|.  When this option is set, the current
+	window scrolls as other scrollbind windows (windows that also have
+	this option set) scroll.  This option is useful for viewing the
+	differences between two versions of a file, see 'diff'.
+	See |'scrollopt'| for options that determine how this option should be
+	interpreted.
+	This option is mostly reset when splitting a window to edit another
+	file.  This means that ":split | edit file" results in two windows
+	with scroll-binding, but ":split file" does not.
+
+			*'scrollfocus'* *'scf'* *'noscrollfocus'* *'noscf'*
+'scrollfocus' 'scf'	boolean  (default off)
+			global
+			{only for MS-Windows GUI}
+	When using the scroll wheel and this option is set, the window under
+	the mouse pointer is scrolled.  With this option off the current
+	window is scrolled.
+	Systems other than MS-Windows always behave like this option is on.
+
+						*'scrolljump'* *'sj'*
+'scrolljump' 'sj'	number	(default 1)
+			global
+	Minimal number of lines to scroll when the cursor gets off the
+	screen (e.g., with "j").  Not used for scroll commands (e.g., CTRL-E,
+	CTRL-D).  Useful if your terminal scrolls very slowly.
+	When set to a negative number from -1 to -100 this is used as the
+	percentage of the window height.  Thus -50 scrolls half the window
+	height.
+	NOTE: This option is set to 1 when 'compatible' is set.
+
+						*'scrolloff'* *'so'*
+'scrolloff' 'so'	number	(default 0, set to 5 in |defaults.vim|)
+			global or local to window |global-local|
+	Minimal number of screen lines to keep above and below the cursor.
+	This will make some context visible around where you are working.  If
+	you set it to a very large value (999) the cursor line will always be
+	in the middle of the window (except at the start or end of the file or
+	when long lines wrap).
+	After using the local value, go back the global value with one of
+	these two: >
+		setlocal scrolloff<
+		setlocal scrolloff=-1
+<	For scrolling horizontally see 'sidescrolloff'.
+	NOTE: This option is set to 0 when 'compatible' is set.
+
+						*'scrollopt'* *'sbo'*
+'scrollopt' 'sbo'	string	(default "ver,jump")
+			global
+	This is a comma-separated list of words that specifies how
+	'scrollbind' windows should behave.  'sbo' stands for ScrollBind
+	Options.
+	The following words are available:
+	    ver		Bind vertical scrolling for 'scrollbind' windows
+	    hor		Bind horizontal scrolling for 'scrollbind' windows
+	    jump	Applies to the offset between two windows for vertical
+			scrolling.  This offset is the difference in the first
+			displayed line of the bound windows.  When moving
+			around in a window, another 'scrollbind' window may
+			reach a position before the start or after the end of
+			the buffer.  The offset is not changed though, when
+			moving back the 'scrollbind' window will try to scroll
+			to the desired position when possible.
+			When now making that window the current one, two
+			things can be done with the relative offset:
+			1. When "jump" is not included, the relative offset is
+			   adjusted for the scroll position in the new current
+			   window.  When going back to the other window, the
+			   new relative offset will be used.
+			2. When "jump" is included, the other windows are
+			   scrolled to keep the same relative offset.  When
+			   going back to the other window, it still uses the
+			   same relative offset.
+	Also see |scroll-binding|.
+	When 'diff' mode is active there always is vertical scroll binding,
+	even when "ver" isn't there.
+
+						*'sections'* *'sect'*
+'sections' 'sect'	string	(default "SHNHH HUnhsh")
+			global
+	Specifies the nroff macros that separate sections.  These are pairs of
+	two letters (See |object-motions|).  The default makes a section start
+	at the nroff macros ".SH", ".NH", ".H", ".HU", ".nh" and ".sh".
+
+						*'secure'* *'nosecure'* *E523*
+'secure'		boolean	(default off)
+			global
+	When on, ":autocmd", shell and write commands are not allowed in
+	".vimrc" and ".exrc" in the current directory and map commands are
+	displayed.  Switch it off only if you know that you will not run into
+	problems, or when the 'exrc' option is off.  On Unix this option is
+	only used if the ".vimrc" or ".exrc" is not owned by you.  This can be
+	dangerous if the systems allows users to do a "chown".  You better set
+	'secure' at the end of your ~/.vimrc then.
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+						*'selection'* *'sel'*
+'selection' 'sel'	string	(default "inclusive")
+			global
+	This option defines the behavior of the selection.  It is only used
+	in Visual and Select mode.
+	Possible values:
+	   value	past line     inclusive ~
+	   old		   no		yes
+	   inclusive	   yes		yes
+	   exclusive	   yes		no
+	"past line" means that the cursor is allowed to be positioned one
+	character past the line.
+	"inclusive" means that the last character of the selection is included
+	in an operation.  For example, when "x" is used to delete the
+	selection.
+	When "old" is used and 'virtualedit' allows the cursor to move past
+	the end of line the line break still isn't included.
+	Note that when "exclusive" is used and selecting from the end
+	backwards, you cannot include the last character of a line, when
+	starting in Normal mode and 'virtualedit' empty.
+
+	The 'selection' option is set by the |:behave| command.
+
+						*'selectmode'* *'slm'*
+'selectmode' 'slm'	string	(default "")
+			global
+	This is a comma-separated list of words, which specifies when to start
+	Select mode instead of Visual mode, when a selection is started.
+	Possible values:
+	   mouse	when using the mouse
+	   key		when using shifted special keys
+	   cmd		when using "v", "V" or CTRL-V
+	See |Select-mode|.
+	The 'selectmode' option is set by the |:behave| command.
+
+						*'sessionoptions'* *'ssop'*
+'sessionoptions' 'ssop'	string	(default: "blank,buffers,curdir,folds,
+					 help,options,tabpages,winsize,terminal")
+			global
+			{not available when compiled without the |+mksession|
+			feature}
+	Changes the effect of the |:mksession| command.  It is a comma
+	separated list of words.  Each word enables saving and restoring
+	something:
+	   word		save and restore ~
+	   blank	empty windows
+	   buffers	hidden and unloaded buffers, not just those in windows
+	   curdir	the current directory
+	   folds	manually created folds, opened/closed folds and local
+			fold options
+	   globals	global variables that start with an uppercase letter
+			and contain at least one lowercase letter.  Only
+			String and Number types are stored.
+	   help		the help window
+	   localoptions	options and mappings local to a window or buffer (not
+			global values for local options)
+	   options	all options and mappings (also global values for local
+			options)
+	   skiprtp	exclude 'runtimepath' and 'packpath' from the options
+	   resize	size of the Vim window: 'lines' and 'columns'
+	   sesdir	the directory in which the session file is located
+			will become the current directory (useful with
+			projects accessed over a network from different
+			systems)
+	   slash	backslashes in file names replaced with forward
+			slashes
+	   tabpages	all tab pages; without this only the current tab page
+			is restored, so that you can make a session for each
+			tab page separately
+	   terminal	include terminal windows where the command can be
+			restored
+	   unix		with Unix end-of-line format (single <NL>), even when
+			on Windows or DOS
+	   winpos	position of the whole Vim window
+	   winsize	window sizes
+
+	Don't include both "curdir" and "sesdir".
+	When neither "curdir" nor "sesdir" is included, file names are stored
+	with absolute paths.
+	If you leave out "options" many things won't work well after restoring
+	the session.
+	"slash" and "unix" are useful on Windows when sharing session files
+	with Unix.  The Unix version of Vim cannot source dos format scripts,
+	but the Windows version of Vim can source unix format scripts.
+
+						*'shell'* *'sh'* *E91*
+'shell' 'sh'		string	(default $SHELL or "sh", Win32: "cmd.exe")
+			global
+	Name of the shell to use for ! and :! commands.  When changing the
+	value also check these options: 'shelltype', 'shellpipe', 'shellslash'
+	'shellredir', 'shellquote', 'shellxquote' and 'shellcmdflag'.
+	It is allowed to give an argument to the command, e.g.  "csh -f".
+	See |option-backslash| about including spaces and backslashes.
+	Environment variables are expanded |:set_env|.
+
+	In |restricted-mode| shell commands will not be possible.  This mode
+	is used if the value of $SHELL ends in "false" or "nologin".
+
+	If the name of the shell contains a space, you need to enclose it in
+	quotes and escape the space.  Example with quotes: >
+		:set shell=\"c:\program\ files\unix\sh.exe\"\ -f
+<	Note the backslash before each quote (to avoid starting a comment) and
+	each space (to avoid ending the option value).  Also note that the
+	"-f" is not inside the quotes, because it is not part of the command
+	name.  Vim automagically recognizes the backslashes that are path
+	separators.
+	Example with escaped space (Vim will do this when initializing the
+	option from $SHELL): >
+		:set shell=/bin/with\\\ space/sh
+<	The resulting value of 'shell' is "/bin/with\ space/sh", two
+	backslashes are consumed by `:set`.
+
+	Under MS-Windows, when the executable ends in ".com" it must be
+	included.  Thus setting the shell to "command.com" or "4dos.com"
+	works, but "command" and "4dos" do not work for all commands (e.g.,
+	filtering).
+	For unknown reasons, when using "4dos.com" the current directory is
+	changed to "C:\".  To avoid this set 'shell' like this: >
+		:set shell=command.com\ /c\ 4dos
+<	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+						*'shellcmdflag'* *'shcf'*
+'shellcmdflag' 'shcf'	string	(default: "-c";
+				 Win32, when 'shell' contains "powershell":
+				 "-Command", or when it does not contain "sh"
+				 somewhere: "/c")
+			global
+	Flag passed to the shell to execute "!" and ":!" commands; e.g.,
+	"bash.exe -c ls", "powershell.exe -Command dir", or "cmd.exe /c dir".
+	For MS-Windows, the default is set according to the value of 'shell',
+	to reduce the need to set this option by the user.
+	On Unix it can have more than one flag.  Each white space separated
+	part is passed as an argument to the shell command.
+	See |option-backslash| about including spaces and backslashes.
+	Also see |dos-shell| and |dos-powershell| for MS-Windows.
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+						*'shellpipe'* *'sp'*
+'shellpipe' 'sp'	string	(default ">", ">%s 2>&1", "| tee", "|& tee"
+				 "2>&1| tee", or
+				 "2>&1 | Out-File -Encoding default")
+			global
+			{not available when compiled without the |+quickfix|
+			feature}
+	String to be used to put the output of the ":make" command in the
+	error file.  See also |:make_makeprg|.  See |option-backslash| about
+	including spaces and backslashes.
+	The name of the temporary file can be represented by "%s" if necessary
+	(the file name is appended automatically if no %s appears in the value
+	of this option).
+	For the Amiga the default is ">".  For MS-Windows using powershell the
+	default is "2>&1 | Out-File -Encoding default", otherwise the default
+	is ">%s 2>&1".  The output is directly saved in a file and not echoed
+	to the screen.
+	For Unix the default is "| tee".  The stdout of the compiler is saved
+	in a file and echoed to the screen.  If the 'shell' option is "csh" or
+	"tcsh" after initializations, the default becomes "|& tee".  If the
+	'shell' option is "sh", "ksh", "mksh", "pdksh", "zsh", "zsh-beta",
+	"bash", "fish", "ash" or "dash" the default becomes "2>&1| tee".  This
+	means that stderr is also included.  Before using the 'shell' option a
+	path is removed, thus "/bin/sh" uses "sh".
+	For Unix and MS-Windows, when the 'shell' option is "pwsh" the default
+	becomes ">%s 2>&1" and the output is not echoed to the screen.
+	The initialization of this option is done after reading the ".vimrc"
+	and the other initializations, so that when the 'shell' option is set
+	there, the 'shellpipe' option changes automatically, unless it was
+	explicitly set before.
+	When 'shellpipe' is set to an empty string, no redirection of the
+	":make" output will be done.  This is useful if you use a 'makeprg'
+	that writes to 'makeef' by itself.  If you want no piping, but do
+	want to include the 'makeef', set 'shellpipe' to a single space.
+	Don't forget to precede the space with a backslash: ":set sp=\ ".
+	In the future pipes may be used for filtering and this option will
+	become obsolete (at least for Unix).
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+						*'shellquote'* *'shq'*
+'shellquote' 'shq'	string	(default: "")
+			global
+	Quoting character(s), put around the command passed to the shell, for
+	the "!" and ":!" commands.  The redirection is kept outside of the
+	quoting.  See 'shellxquote' to include the redirection.  It's
+	probably not useful to set both options.
+	This is an empty string by default.  Only known to be useful for
+	third-party shells on MS-Windows-like systems, such as the MKS Korn
+	Shell or bash, where it should be "\"".  See |dos-shell|.
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+						*'shellredir'* *'srr'*
+'shellredir' 'srr'	string	(default ">", ">&", ">%s 2>&1", or
+				 "2>&1 | Out-File -Encoding default")
+			global
+	String to be used to put the output of a filter command in a temporary
+	file.  See also |:!|.  See |option-backslash| about including spaces
+	and backslashes.
+	The name of the temporary file can be represented by "%s" if necessary
+	(the file name is appended automatically if no %s appears in the value
+	of this option).
+	The default is ">".  For Unix, if the 'shell' option is "csh" or
+	"tcsh" during initializations, the default becomes ">&".  If the
+	'shell' option is "sh", "ksh", "mksh", "pdksh", "zsh", "zsh-beta",
+	"bash", "fish", or "pwsh", the default becomes ">%s 2>&1".  This means
+	that stderr is also included.  For Win32, the Unix checks are done and
+	additionally "cmd" is checked for, which makes the default ">%s 2>&1",
+	and "powershell" is checked for which makes the default
+	"2>&1 | Out-File -Encoding default" (see |dos-powershell|).  Also, the
+	same names with ".exe" appended are checked for.
+	The initialization of this option is done after reading the ".vimrc"
+	and the other initializations, so that when the 'shell' option is set
+	there, the 'shellredir' option changes automatically unless it was
+	explicitly set before.
+	In the future pipes may be used for filtering and this option will
+	become obsolete (at least for Unix).
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+			*'shellslash'* *'ssl'* *'noshellslash'* *'nossl'*
+'shellslash' 'ssl'	boolean	(default off)
+			global
+			{only for MS-Windows}
+	When set, a forward slash is used when expanding file names.  This is
+	useful when a Unix-like shell is used instead of cmd.exe, pwsh.exe, or
+	powershell.exe.  Backward slashes can still be typed, but they are
+	changed to forward slashes by Vim.
+	Note that setting or resetting this option has no effect for some
+	existing file names, thus this option needs to be set before opening
+	any file for best results.  This might change in the future.
+	'shellslash' only works when a backslash can be used as a path
+	separator.  To test if this is so use: >
+		if exists('+shellslash')
+<	Also see 'completeslash'.
+
+			*'shelltemp'* *'stmp'* *'noshelltemp'* *'nostmp'*
+'shelltemp' 'stmp'	boolean	(Vi default off, Vim default on)
+			global
+	When on, use temp files for shell commands.  When off use a pipe.
+	When using a pipe is not possible temp files are used anyway.
+	Currently a pipe is only supported on Unix and MS-Windows 2K and
+	later.  You can check it with: >
+		:if has("filterpipe")
+<	The advantage of using a pipe is that nobody can read the temp file
+	and the 'shell' command does not need to support redirection.
+	The advantage of using a temp file is that the file type and encoding
+	can be detected.
+	The |FilterReadPre|, |FilterReadPost| and |FilterWritePre|,
+	|FilterWritePost| autocommands event are not triggered when
+	'shelltemp' is off.
+	The `system()` function does not respect this option and always uses
+	temp files.
+	NOTE: This option is set to the Vim default value when 'compatible'
+	is reset.
+
+						*'shelltype'* *'st'*
+'shelltype' 'st'	number	(default 0)
+			global
+			{only for the Amiga}
+	On the Amiga this option influences the way how the commands work
+	which use a shell.
+	0 and 1: always use the shell
+	2 and 3: use the shell only to filter lines
+	4 and 5: use shell only for ':sh' command
+	When not using the shell, the command is executed directly.
+
+	0 and 2: use "shell 'shellcmdflag' cmd" to start external commands
+	1 and 3: use "shell cmd" to start external commands
+
+						*'shellxescape'* *'sxe'*
+'shellxescape' 'sxe'	string	(default: "";
+				 for MS-Windows: "\"&|<>()@^")
+			global
+	When 'shellxquote' is set to "(" then the characters listed in this
+	option will be escaped with a '^' character.  This makes it possible
+	to execute most external commands with cmd.exe.
+
+						*'shellxquote'* *'sxq'*
+'shellxquote' 'sxq'	string	(default: "";
+					for Win32, when 'shell' is cmd.exe: "("
+					for Win32, when 'shell' is
+					powershell.exe: "\""
+					for Win32, when 'shell' contains "sh"
+					somewhere: "\""
+					for Unix, when using system(): "\"")
+			global
+	Quoting character(s), put around the command passed to the shell, for
+	the "!" and ":!" commands.  Includes the redirection.  See
+	'shellquote' to exclude the redirection.  It's probably not useful
+	to set both options.
+	When the value is '(' then ')' is appended. When the value is '"('
+	then ')"' is appended.
+	When the value is '(' then also see 'shellxescape'.
+	This is an empty string by default on most systems, but is known to be
+	useful for on Win32 version, either for cmd.exe, powershell.exe, or
+	pwsh.exe which automatically strips off the first and last quote on a
+	command, or 3rd-party shells such as the MKS Korn Shell or bash, where
+	it should be "\"".  The default is adjusted according the value of
+	'shell', to reduce the need to set this option by the user.  See
+	|dos-shell|.
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+			*'shiftround'* *'sr'* *'noshiftround'* *'nosr'*
+'shiftround' 'sr'	boolean	(default off)
+			global
+	Round indent to multiple of 'shiftwidth'.  Applies to > and <
+	commands.  CTRL-T and CTRL-D in Insert mode always round the indent to
+	a multiple of 'shiftwidth' (this is Vi compatible).
+	NOTE: This option is reset when 'compatible' is set.
+
+						*'shiftwidth'* *'sw'*
+'shiftwidth' 'sw'	number	(default 8)
+			local to buffer
+	Number of spaces to use for each step of (auto)indent.  Used for
+	|'cindent'|, |>>|, |<<|, etc.
+	When zero the 'tabstop' value will be used.  Use the |shiftwidth()|
+	function to get the effective shiftwidth value.
+
+						*'shortmess'* *'shm'*
+'shortmess' 'shm'	string	(Vim default "filnxtToOS", Vi default: "S",
+							POSIX default: "AS")
+			global					*E1336*
+	This option helps to avoid all the |hit-enter| prompts caused by file
+	messages, for example  with CTRL-G, and to avoid some other messages.
+	It is a list of flags:
+	 flag	meaning when present	~
+	  f	use "(3 of 5)" instead of "(file 3 of 5)"		*shm-f*
+	  i	use "[noeol]" instead of "[Incomplete last line]"	*shm-i*

+	  x	use "[dos]" instead of "[dos format]", "[unix]"		*shm-x*
+		instead of "[unix format]" and "[mac]" instead of "[mac
+		format]"
+	  a	all of the above abbreviations				*shm-a*
+
+	  o	overwrite message for writing a file with subsequent	*shm-o*
+		message for reading a file (useful for ":wn" or when
+		'autowrite' on)
+	  O	message for reading a file overwrites any previous	*shm-O*
+		message;  also for quickfix message (e.g., ":cn")
+	  s	don't give "search hit BOTTOM, continuing at TOP" or	*shm-s*
+		"search hit TOP, continuing at BOTTOM" messages; when using
+		the search count do not show "W" after the count message (see
+		S below)
+	  t	truncate file message at the start if it is too long	*shm-t*
+		to fit on the command-line, "<" will appear in the left most
+		column; ignored in Ex mode
+	  T	truncate other messages in the middle if they are too	*shm-T*
+		long to fit on the command line; "..." will appear in the

+		`:silent` was used for the command; note that this also
+		affects messages from autocommands
+	  S	do not show search count message when searching, e.g.	*shm-S*
+		"[1/5]"
+
+	This gives you the opportunity to avoid that a change between buffers
+	requires you to hit <Enter>, but still gives as useful a message as
+	possible for the space available.  To get the whole message that you
+	would have got with 'shm' empty, use ":file!"
+	Useful values:
+	    shm=	No abbreviation of message.
+	    shm=a	Abbreviation, but no loss of information.
+	    shm=at	Abbreviation, and truncate message when necessary.
+
+	NOTE: This option is set to the Vi default value when 'compatible' is
+	set and to the Vim default value when 'compatible' is reset.
+
+				 *'shortname'* *'sn'* *'noshortname'* *'nosn'*
+'shortname' 'sn'	boolean	(default off)
+			local to buffer
+	Filenames are assumed to be 8 characters plus one extension of 3
+	characters.  Multiple dots in file names are not allowed.  When this
+	option is on, dots in file names are replaced with underscores when
+	adding an extension (".~" or ".swp").  This option is useful
+	when editing files on an MS-DOS compatible filesystem, e.g., messydos
+	or crossdos.
+
+						*'showbreak'* *'sbr'* *E595*
+'showbreak' 'sbr'	string	(default "")
+			global or local to window |global-local|
+			{not available when compiled without the |+linebreak|
+			feature}
+	String to put at the start of lines that have been wrapped.  Useful
+	values are "> " or "+++ ": >
+		:set showbreak=>\ 
+<	Note the backslash to escape the trailing space.  It's easier like
+	this: >
+		:let &showbreak = '+++ '
+<	Only printable single-cell characters are allowed, excluding <Tab> and
+	comma (in a future version the comma might be used to separate the
+	part that is shown at the end and at the start of a line).
+	The characters are highlighted according to the '@' flag in
+	'highlight'.
+	Note that tabs after the showbreak will be displayed differently.
+	If you want the 'showbreak' to appear in between line numbers, add the
+	"n" flag to 'cpoptions'.
+	A window-local value overrules a global value.  If the global value is
+	set and you want no value in the current window use NONE: >
+		:setlocal showbreak=NONE

+				     *'showcmd'* *'sc'* *'noshowcmd'* *'nosc'*
+'showcmd' 'sc'		boolean	(Vim default: on, off for Unix,
+				       Vi default: off, set in |defaults.vim|)
+			global
+	Show (partial) command in the last line of the screen.  Set this
+	option off if your terminal is slow.
+	In Visual mode the size of the selected area is shown:
+	- When selecting characters within a line, the number of characters.
+	  If the number of bytes is different it is also displayed: "2-6"
+	  means two characters and six bytes.
+	- When selecting more than one line, the number of lines.
+	- When selecting a block, the size in screen characters:
+	  {lines}x{columns}.
+	This information can be displayed in an alternative location using the
+	'showcmdloc' option.
+	NOTE: This option is set to the Vi default value when 'compatible' is
+	set and to the Vim default value when 'compatible' is reset.
+
+			*'showcmdloc'* *'sloc'*
+'showcmdloc' 'sloc'	string	(default "last")
+			global
+	This option can be used to display the (partially) entered command in
+	another location.  Possible values are:
+	  last		Last line of the screen (default).
+	  statusline	Status line of the current window.
+	  tabline	First line of the screen if 'showtabline' is enabled.
+	Setting this option to "statusline" or "tabline" means that these will
+	be redrawn whenever the command changes, which can be on every key
+	pressed.
+	The %S 'statusline' item can be used in 'statusline' or 'tabline' to
+	place the text.  Without a custom 'statusline' or 'tabline' it will be
+	displayed in a convenient location.
+
+			*'showfulltag'* *'sft'* *'noshowfulltag'* *'nosft'*
+'showfulltag' 'sft'	boolean (default off)
+			global
+	When completing a word in insert mode (see |ins-completion|) from the
+	tags file, show both the tag name and a tidied-up form of the search
+	pattern (if there is one) as possible matches.  Thus, if you have
+	matched a C function, you can see a template for what arguments are
+	required (coding style permitting).
+	Note that this doesn't work well together with having "longest" in
+	'completeopt', because the completion from the search pattern may not
+	match the typed text.
+
+				 *'showmatch'* *'sm'* *'noshowmatch'* *'nosm'*
+'showmatch' 'sm'	boolean	(default off)
+			global
+	When a bracket is inserted, briefly jump to the matching one.  The
+	jump is only done if the match can be seen on the screen.  The time to
+	show the match can be set with 'matchtime'.
+	A Beep is given if there is no match (no matter if the match can be
+	seen or not).
+	This option is reset when 'paste' is set and restored when 'paste' is
+	reset.
+	When the 'm' flag is not included in 'cpoptions', typing a character
+	will immediately move the cursor back to where it belongs.
+	See the "sm" field in 'guicursor' for setting the cursor shape and
+	blinking when showing the match.
+	The 'matchpairs' option can be used to specify the characters to show
+	matches for.  'rightleft' and 'revins' are used to look for opposite
+	matches.
+	Also see the matchparen plugin for highlighting the match when moving
+	around |pi_paren.txt|.
+	Note: Use of the short form is rated PG.
+
+				 *'showmode'* *'smd'* *'noshowmode'* *'nosmd'*
+'showmode' 'smd'	boolean	(Vim default: on, Vi default: off)
+			global
+	If in Insert, Replace or Visual mode put a message on the last line.
+	Use the 'M' flag in 'highlight' to set the type of highlighting for
+	this message.
+	When |XIM| may be used the message will include "XIM".  But this
+	doesn't mean XIM is really active, especially when 'imactivatekey' is
+	not set.
+	NOTE: This option is set to the Vi default value when 'compatible' is
+	set and to the Vim default value when 'compatible' is reset.
+
+						*'showtabline'* *'stal'*
+'showtabline' 'stal'	number	(default 1)
+			global
+	The value of this option specifies when the line with tab page labels
+	will be displayed:
+		0: never
+		1: only if there are at least two tab pages
+		2: always
+	This is both for the GUI and non-GUI implementation of the tab pages
+	line.
+	See |tab-page| for more information about tab pages.
+
+						*'sidescroll'* *'ss'*
+'sidescroll' 'ss'	number	(default 0)
+			global
+	The minimal number of columns to scroll horizontally.  Used only when
+	the 'wrap' option is off and the cursor is moved off of the screen.
+	When it is zero the cursor will be put in the middle of the screen.
+	When using a slow terminal set it to a large number or 0.  When using
+	a fast terminal use a small number or 1.  Not used for "zh" and "zl"
+	commands.
+
+						*'sidescrolloff'* *'siso'*
+'sidescrolloff' 'siso'	number (default 0)
+			global or local to window |global-local|
+	The minimal number of screen columns to keep to the left and to the
+	right of the cursor if 'nowrap' is set.  Setting this option to a
+	value greater than 0 while having |'sidescroll'| also at a non-zero
+	value makes some context visible in the line you are scrolling in
+	horizontally (except at beginning of the line).  Setting this option
+	to a large value (like 999) has the effect of keeping the cursor
+	horizontally centered in the window, as long as one does not come too
+	close to the beginning of the line.
+	After using the local value, go back the global value with one of
+	these two: >
+		setlocal sidescrolloff<
+		setlocal sidescrolloff=-1
+<	NOTE: This option is set to 0 when 'compatible' is set.
+
+	Example: Try this together with 'sidescroll' and 'listchars' as
+		 in the following example to never allow the cursor to move
+		 onto the "extends" character: >
+
+		 :set nowrap sidescroll=1 listchars=extends:>,precedes:<
+		 :set sidescrolloff=1
+<
+						*'signcolumn'* *'scl'*
+'signcolumn' 'scl'	string	(default "auto")
+			local to window
+			{not available when compiled without the |+signs|
+			feature}
+	Whether or not to draw the signcolumn. Valid values are:
+	   "auto"	only when there is a sign to display
+	   "no"		never
+	   "yes"	always
+	   "number"	display signs in the 'number' column. If the number
+			column is not present, then behaves like "auto".
+
+
+			*'smartcase'* *'scs'* *'nosmartcase'* *'noscs'*
+'smartcase' 'scs'	boolean	(default off)
+			global
+	Override the 'ignorecase' option if the search pattern contains upper
+	case characters.  Only used when the search pattern is typed and
+	'ignorecase' option is on.  Used for the commands "/", "?", "n", "N",
+	":g" and ":s".  Not used for "*", "#", "gd", tag search, etc.  After
+	"*" and "#" you can make 'smartcase' used by doing a "/" command,
+	recalling the search pattern from history and hitting <Enter>.
+	NOTE: This option is reset when 'compatible' is set.
+
+			     *'smartindent'* *'si'* *'nosmartindent'* *'nosi'*
+'smartindent' 'si'	boolean	(default off)
+			local to buffer
+	Do smart autoindenting when starting a new line.  Works for C-like
+	programs, but can also be used for other languages.  'cindent' does
+	something like this, works better in most cases, but is more strict,
+	see |C-indenting|.  When 'cindent' is on or 'indentexpr' is set,
+	setting 'si' has no effect.  'indentexpr' is a more advanced
+	alternative.
+	Normally 'autoindent' should also be on when using 'smartindent'.
+	An indent is automatically inserted:
+	- After a line ending in '{'.
+	- After a line starting with a keyword from 'cinwords'.
+	- Before a line starting with '}' (only with the "O" command).
+	When typing '}' as the first character in a new line, that line is
+	given the same indent as the matching '{'.
+	When typing '#' as the first character in a new line, the indent for
+	that line is removed, the '#' is put in the first column.  The indent
+	is restored for the next line.  If you don't want this, use this
+	mapping: ":inoremap # X^H#", where ^H is entered with CTRL-V CTRL-H.
+	When using the ">>" command, lines starting with '#' are not shifted
+	right.
+	NOTE: This option is reset when 'compatible' is set.
+	This option is reset when 'paste' is set and restored when 'paste' is
+	reset.
+
+				 *'smarttab'* *'sta'* *'nosmarttab'* *'nosta'*
+'smarttab' 'sta'	boolean	(default off)
+			global
+	When on, a <Tab> in front of a line inserts blanks according to
+	'shiftwidth'.  'tabstop' or 'softtabstop' is used in other places.  A
+	<BS> will delete a 'shiftwidth' worth of space at the start of the
+	line.
+	When off, a <Tab> always inserts blanks according to 'tabstop' or
+	'softtabstop'.  'shiftwidth' is only used for shifting text left or
+	right |shift-left-right|.
+	What gets inserted (a <Tab> or spaces) depends on the 'expandtab'
+	option.  Also see |ins-expandtab|.  When 'expandtab' is not set, the
+	number of spaces is minimized by using <Tab>s.
+	This option is reset when 'paste' is set and restored when 'paste' is
+	reset.
+	NOTE: This option is reset when 'compatible' is set.
+
+			*'smoothscroll'* *'sms'* *'nosmoothscroll'* *'nosms'*
+'smoothscroll' 'sms'	boolean  (default off)
+			local to window
+	Scrolling works with screen lines.  When 'wrap' is set and the first
+	line in the window wraps part of it may not be visible, as if it is
+	above the window. "<<<" is displayed at the start of the first line,
+	highlighted with |hl-NonText|.
+	You may also want to add "lastline" to the 'display' option to show as
+	much of the last line as possible.
+	NOTE: only partly implemented, currently works with CTRL-E, CTRL-Y
+	and scrolling with the mouse.
+
+					*'softtabstop'* *'sts'*
+'softtabstop' 'sts'	number	(default 0)
+			local to buffer
+	Number of spaces that a <Tab> counts for while performing editing
+	operations, like inserting a <Tab> or using <BS>.  It "feels" like
+	<Tab>s are being inserted, while in fact a mix of spaces and <Tab>s is
+	used.  This is useful to keep the 'ts' setting at its standard value
+	of 8, while being able to edit like it is set to 'sts'.  However,
+	commands like "x" still work on the actual characters.
+	When 'sts' is zero, this feature is off.
+	When 'sts' is negative, the value of 'shiftwidth' is used.
+	'softtabstop' is set to 0 when the 'paste' option is set and restored
+	when 'paste' is reset.
+	See also |ins-expandtab|.  When 'expandtab' is not set, the number of
+	spaces is minimized by using <Tab>s.
+	The 'L' flag in 'cpoptions' changes how tabs are used when 'list' is
+	set.
+	NOTE: This option is set to 0 when 'compatible' is set.
+
+	If Vim is compiled with the |+vartabs| feature then the value of
+	'softtabstop' will be ignored if |'varsofttabstop'| is set to
+	anything other than an empty string.
+
+						*'spell'* *'nospell'*
+'spell'			boolean	(default off)
+			local to window
+			{not available when compiled without the |+syntax|
+			feature}
+	When on spell checking will be done.  See |spell|.
+	The languages are specified with 'spelllang'.
+
+						*'spellcapcheck'* *'spc'*
+'spellcapcheck' 'spc'	string	(default "[.?!]\_[\])'" \t]\+")
+			local to buffer
+			{not available when compiled without the |+syntax|
+			feature}
+	Pattern to locate the end of a sentence.  The following word will be
+	checked to start with a capital letter.  If not then it is highlighted
+	with SpellCap |hl-SpellCap| (unless the word is also badly spelled).
+	When this check is not wanted make this option empty.
+	Only used when 'spell' is set.
+	Be careful with special characters, see |option-backslash| about
+	including spaces and backslashes.
+	To set this option automatically depending on the language, see
+	|set-spc-auto|.
+
+						*'spellfile'* *'spf'*
+'spellfile' 'spf'	string	(default empty)
+			local to buffer
+			{not available when compiled without the |+syntax|
+			feature}
+	Name of the word list file where words are added for the |zg| and |zw|
+	commands.  It must end in ".{encoding}.add".  You need to include the
+	path, otherwise the file is placed in the current directory.
+	The path may include characters from 'isfname', space, comma and '@'.
+								*E765*
+	It may also be a comma-separated list of names.  A count before the
+	|zg| and |zw| commands can be used to access each.  This allows using
+	a personal word list file and a project word list file.
+	When a word is added while this option is empty Vim will set it for
+	you: Using the first directory in 'runtimepath' that is writable.  If
+	there is no "spell" directory yet it will be created.  For the file
+	name the first language name that appears in 'spelllang' is used,
+	ignoring the region.
+	The resulting ".spl" file will be used for spell checking, it does not
+	have to appear in 'spelllang'.
+	Normally one file is used for all regions, but you can add the region
+	name if you want to.  However, it will then only be used when
+	'spellfile' is set to it, for entries in 'spelllang' only files
+	without region name will be found.
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+						*'spelllang'* *'spl'*
+'spelllang' 'spl'	string	(default "en")
+			local to buffer
+			{not available when compiled without the |+syntax|
+			feature}
+	A comma-separated list of word list names.  When the 'spell' option is
+	on spellchecking will be done for these languages.  Example: >
+		set spelllang=en_us,nl,medical
+<	This means US English, Dutch and medical words are recognized.  Words
+	that are not recognized will be highlighted.
+	The word list name must consist of alphanumeric characters, a dash or
+	an underscore.  It should not include a comma or dot.  Using a dash is
+	recommended to separate the two letter language name from a
+	specification.  Thus "en-rare" is used for rare English words.
+	A region name must come last and have the form "_xx", where "xx" is
+	the two-letter, lower case region name.  You can use more than one
+	region by listing them: "en_us,en_ca" supports both US and Canadian
+	English, but not words specific for Australia, New Zealand or Great
+	Britain. (Note: currently en_au and en_nz dictionaries are older than
+	en_ca, en_gb and en_us).
+	If the name "cjk" is included East Asian characters are excluded from
+	spell checking.  This is useful when editing text that also has Asian
+	words.
+	Note that the "medical" dictionary does not exist, it is just an
+	example of a longer name.
+							*E757*
+	As a special case the name of a .spl file can be given as-is.  The
+	first "_xx" in the name is removed and used as the region name
+	(_xx is an underscore, two letters and followed by a non-letter).
+	This is mainly for testing purposes.  You must make sure the correct
+	encoding is used, Vim doesn't check it.
+	When 'encoding' is set the word lists are reloaded.  Thus it's a good
+	idea to set 'spelllang' after setting 'encoding' to avoid loading the
+	files twice.
+	How the related spell files are found is explained here: |spell-load|.
+
+	If the |spellfile.vim| plugin is active and you use a language name
+	for which Vim cannot find the .spl file in 'runtimepath' the plugin
+	will ask you if you want to download the file.
+
+	After this option has been set successfully, Vim will source the files
+	"spell/LANG.vim" in 'runtimepath'.  "LANG" is the value of 'spelllang'
+	up to the first character that is not an ASCII letter or number and
+	not a dash.  Also see |set-spc-auto|.
+
+						*'spelloptions'* *'spo'*
+'spelloptions' 'spo'	string	(default "")
+			local to buffer
+			{not available when compiled without the |+syntax|
+			feature}
+	A comma-separated list of options for spell checking:
+	   camel	When a word is CamelCased, assume "Cased" is a
+			separate word: every upper-case character in a word
+			that comes after a lower case character indicates the
+			start of a new word.
+
+						*'spellsuggest'* *'sps'*
+'spellsuggest' 'sps'	string	(default "best")
+			global
+			{not available when compiled without the |+syntax|
+			feature}
+	Methods used for spelling suggestions.  Both for the |z=| command and
+	the |spellsuggest()| function.  This is a comma-separated list of
+	items:
+
+	best		Internal method that works best for English.  Finds
+			changes like "fast" and uses a bit of sound-a-like
+			scoring to improve the ordering.
+
+	double		Internal method that uses two methods and mixes the
+			results.  The first method is "fast", the other method
+			computes how much the suggestion sounds like the bad
+			word.  That only works when the language specifies
+			sound folding.  Can be slow and doesn't always give
+			better results.
+
+	fast		Internal method that only checks for simple changes:
+			character inserts/deletes/swaps.  Works well for
+			simple typing mistakes.
+
+	{number}	The maximum number of suggestions listed for |z=|.
+			Not used for |spellsuggest()|.  The number of
+			suggestions is never more than the value of 'lines'
+			minus two.
+
+	timeout:{millisec}   Limit the time searching for suggestions to
+			{millisec} milli seconds.  Applies to the following
+			methods.  When omitted the limit is 5000. When
+			negative there is no limit.  {only works when built
+			with the |+reltime| feature}
+
+	file:{filename} Read file {filename}, which must have two columns,
+			separated by a slash.  The first column contains the
+			bad word, the second column the suggested good word.
+			Example:
+				theribal/terrible ~
+			Use this for common mistakes that do not appear at the
+			top of the suggestion list with the internal methods.
+			Lines without a slash are ignored, use this for
+			comments.
+			The word in the second column must be correct,
+			otherwise it will not be used.  Add the word to an
+			".add" file if it is currently flagged as a spelling
+			mistake.
+			The file is used for all languages.
+
+	expr:{expr}	Evaluate expression {expr}.  Use a function to avoid
+			trouble with spaces.  Best is to call a function
+			without arguments, see |expr-option-function|.
+			|v:val| holds the badly spelled word.  The expression
+			must evaluate to a List of Lists, each with a
+			suggestion and a score.
+			Example:
+				[['the', 33], ['that', 44]] ~
+			Set 'verbose' and use |z=| to see the scores that the
+			internal methods use.  A lower score is better.
+			This may invoke |spellsuggest()| if you temporarily
+			set 'spellsuggest' to exclude the "expr:" part.
+			Errors are silently ignored, unless you set the
+			'verbose' option to a non-zero value.
+
+	Only one of "best", "double" or "fast" may be used.  The others may
+	appear several times in any order.  Example: >
+		:set sps=file:~/.vim/sugg,best,expr:MySuggest()
+<
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+
+			*'splitbelow'* *'sb'* *'nosplitbelow'* *'nosb'*
+'splitbelow' 'sb'	boolean	(default off)
+			global
+	When on, splitting a window will put the new window below the current
+	one. |:split|
+
+			*'splitkeep'* *'spk'*
+'splitkeep' 'spk'	string	(default "cursor")
+			global
+	The value of this option determines the scroll behavior when opening,
+	closing or resizing horizontal splits.
+
+	Possible values are:
+	  cursor	Keep the same relative cursor position.
+	  screen	Keep the text on the same screen line.
+	  topline	Keep the topline the same.
+
+	For the "screen" and "topline" values, the cursor position will be
+	changed when necessary. In this case, the jumplist will be populated
+	with the previous cursor position. For "screen", the text cannot always
+	be kept on the same screen line when 'wrap' is enabled.
+
+			*'splitright'* *'spr'* *'nosplitright'* *'nospr'*
+'splitright' 'spr'	boolean	(default off)
+			global
+	When on, splitting a window will put the new window right of the
+	current one. |:vsplit|
+
+			   *'startofline'* *'sol'* *'nostartofline'* *'nosol'*
+'startofline' 'sol'	boolean	(default on)
+			global
+	When "on" the commands listed below move the cursor to the first
+	non-blank of the line.  When off the cursor is kept in the same column
+	(if possible).  This applies to the commands:
+	- CTRL-D, CTRL-U, CTRL-B, CTRL-F, "G", "H", "M", "L", "gg"
+	- "d", "<<" and ">>" with a linewise operator
+	- "%" with a count
+	- buffer changing commands (CTRL-^, :bnext, :bNext, etc.)
+	- Ex commands that only has a line number, e.g., ":25" or ":+".
+	In case of buffer changing commands the cursor is placed at the column
+	where it was the last time the buffer was edited.
+	NOTE: This option is set when 'compatible' is set.
+
+			   *'statusline'* *'stl'* *E540* *E542*
+'statusline' 'stl'	string	(default empty)
+			global or local to window |global-local|
+			{not available when compiled without the |+statusline|
+			feature}
+	When non-empty, this option determines the content of the status line.
+	Also see |status-line|.
+
+	The option consists of printf style '%' items interspersed with
+	normal text.  Each status line item is of the form:
+	  %-0{minwid}.{maxwid}{item}
+	All fields except the {item} are optional.  A single percent sign can
+	be given as "%%".
+
+	When the option starts with "%!" then it is used as an expression,
+	evaluated and the result is used as the option value.  Example: >
+		:set statusline=%!MyStatusLine()
+<	The *g:statusline_winid* variable will be set to the |window-ID| of the
+	window that the status line belongs to.
+	The result can contain %{} items that will be evaluated too.
+	Note that the "%!" expression is evaluated in the context of the
+	current window and buffer, while %{} items are evaluated in the
+	context of the window that the statusline belongs to.
+
+	When there is error while evaluating the option then it will be made
+	empty to avoid further errors.  Otherwise screen updating would loop.
+	When the result contains unprintable characters the result is
+	unpredictable.
+
+	Note that the only effect of 'ruler' when this option is set (and
+	'laststatus' is 2) is controlling the output of |CTRL-G|.
+
+	field	    meaning ~
+	-	    Left justify the item.  The default is right justified
+		    when minwid is larger than the length of the item.
+	0	    Leading zeroes in numeric items.  Overridden by '-'.
+	minwid	    Minimum width of the item, padding as set by '-' & '0'.
+		    Value must be 50 or less.
+	maxwid	    Maximum width of the item.  Truncation occurs with a '<'
+		    on the left for text items.  Numeric items will be
+		    shifted down to maxwid-2 digits followed by '>'number
+		    where number is the amount of missing digits, much like
+		    an exponential notation.
+	item	    A one letter code as described below.
+
+	Following is a description of the possible statusline items.  The
+	second character in "item" is the type:
+		N for number
+		S for string
+		F for flags as described below
+		- not applicable
+
+	item  meaning ~
+	f S   Path to the file in the buffer, as typed or relative to current
+	      directory.
+	F S   Full path to the file in the buffer.
+	t S   File name (tail) of file in the buffer.
+	m F   Modified flag, text is "[+]"; "[-]" if 'modifiable' is off.
+	M F   Modified flag, text is ",+" or ",-".
+	r F   Readonly flag, text is "[RO]".
+	R F   Readonly flag, text is ",RO".
+	h F   Help buffer flag, text is "[help]".
+	H F   Help buffer flag, text is ",HLP".
+	w F   Preview window flag, text is "[Preview]".
+	W F   Preview window flag, text is ",PRV".
+	y F   Type of file in the buffer, e.g., "[vim]".  See 'filetype'.
+	Y F   Type of file in the buffer, e.g., ",VIM".  See 'filetype'.
+	q S   "[Quickfix List]", "[Location List]" or empty.
+	k S   Value of "b:keymap_name" or 'keymap' when |:lmap| mappings are
+	      being used: "<keymap>"
+	n N   Buffer number.
+	b N   Value of character under cursor.
+	B N   As above, in hexadecimal.
+	o N   Byte number in file of byte under cursor, first byte is 1.
+	      Mnemonic: Offset from start of file (with one added)
+	      {not available when compiled without |+byte_offset| feature}
+	O N   As above, in hexadecimal.
+	N N   Printer page number.  (Only works in the 'printheader' option.)
+	l N   Line number.
+	L N   Number of lines in buffer.
+	c N   Column number (byte index).
+	v N   Virtual column number (screen column).
+	V N   Virtual column number as -{num}.  Not displayed if equal to 'c'.
+	p N   Percentage through file in lines as in |CTRL-G|.
+	P S   Percentage through file of displayed window.  This is like the
+	      percentage described for 'ruler'.  Always 3 in length, unless
+	      translated.
+	S S   'showcmd' content, see 'showcmdloc'.
+	a S   Argument list status as in default title.  ({current} of {max})
+	      Empty if the argument file count is zero or one.
+	{ NF  Evaluate expression between '%{' and '}' and substitute result.
+	      Note that there is no '%' before the closing '}'.  The
+	      expression cannot contain a '}' character, call a function to
+	      work around that.  See |stl-%{| below.
+	{% -  This is almost same as { except the result of the expression is
+	      re-evaluated as a statusline format string.  Thus if the
+	      return value of expr contains % items they will get expanded.
+	      The expression can contain the } character, the end of
+	      expression is denoted by %}.
+	      For example: >
+		func! Stl_filename() abort
+		    return "%t"
+		endfunc
+<	        `stl=%{Stl_filename()}`   results in `"%t"`
+	        `stl=%{%Stl_filename()%}` results in `"Name of current file"`
+	%} -  End of `{%` expression
+	( -   Start of item group.  Can be used for setting the width and
+	      alignment of a section.  Must be followed by %) somewhere.
+	) -   End of item group.  No width fields allowed.
+	T N   For 'tabline': start of tab page N label.  Use %T after the last
+	      label.  This information is used for mouse clicks.
+	X N   For 'tabline': start of close tab N label.  Use %X after the
+	      label, e.g.: %3Xclose%X.  Use %999X for a "close current tab"
+	      mark.  This information is used for mouse clicks.
+	< -   Where to truncate line if too long.  Default is at the start.
+	      No width fields allowed.
+	= -   Separation point between alignment sections.  Each section will
+	      be separated by an equal number of spaces.  With one %= what
+	      comes after it will be right-aligned.  With two %= there is a
+	      middle part, with white space left and right of it.
+	      No width fields allowed.
+	# -   Set highlight group.  The name must follow and then a # again.
+	      Thus use %#HLname# for highlight group HLname.  The same
+	      highlighting is used, also for the statusline of non-current
+	      windows.
+	* -   Set highlight group to User{N}, where {N} is taken from the
+	      minwid field, e.g. %1*.  Restore normal highlight with %* or %0*.
+	      The difference between User{N} and StatusLine will be applied to
+	      StatusLineNC for the statusline of non-current windows.
+	      The number N must be between 1 and 9.  See |hl-User1..9|
+
+	When displaying a flag, Vim removes the leading comma, if any, when
+	that flag comes right after plaintext.  This will make a nice display
+	when flags are used like in the examples below.
+
+	When all items in a group becomes an empty string (i.e. flags that are
+	not set) and a minwid is not set for the group, the whole group will
+	become empty.  This will make a group like the following disappear
+	completely from the statusline when none of the flags are set. >
+		:set statusline=...%(\ [%M%R%H]%)...
+<	Beware that an expression is evaluated each and every time the status
+	line is displayed.
+				*stl-%{* *g:actual_curbuf* *g:actual_curwin*
+	While evaluating %{} the current buffer and current window will be set
+	temporarily to that of the window (and buffer) whose statusline is
+	currently being drawn.  The expression will evaluate in this context.
+	The variable "g:actual_curbuf" is set to the `bufnr()` number of the
+	real current buffer and "g:actual_curwin" to the |window-ID| of the
+	real current window.  These values are strings.
+
+	The 'statusline' option will be evaluated in the |sandbox| if set from
+	a modeline, see |sandbox-option|.
+	This option cannot be set in a modeline when 'modelineexpr' is off.
+
+	It is not allowed to change text or jump to another window while
+	evaluating 'statusline' |textlock|.
+
+	If the statusline is not updated when you want it (e.g., after setting
+	a variable that's used in an expression), you can force an update by
+	using `:redrawstatus`.
+
+	A result of all digits is regarded a number for display purposes.
+	Otherwise the result is taken as flag text and applied to the rules
+	described above.
+
+	Watch out for errors in expressions.  They may render Vim unusable!
+	If you are stuck, hold down ':' or 'Q' to get a prompt, then quit and
+	edit your .vimrc or whatever with "vim --clean" to get it right.

+						*'suffixes'* *'su'*
+'suffixes' 'su'		string	(default ".bak,~,.o,.h,.info,.swp,.obj")
+			global
+	Files with these suffixes get a lower priority when multiple files
+	match a wildcard.  See |suffixes|.  Commas can be used to separate the
+	suffixes.  Spaces after the comma are ignored.  A dot is also seen as
+	the start of a suffix.  To avoid a dot or comma being recognized as a
+	separator, precede it with a backslash (see |option-backslash| about
+	including spaces and backslashes).
+	See 'wildignore' for completely ignoring files.
+	The use of |:set+=| and |:set-=| is preferred when adding or removing
+	suffixes from the list.  This avoids problems when a future version
+	uses another default.
+
+						*'suffixesadd'* *'sua'*
+'suffixesadd' 'sua'	string	(default "")
+			local to buffer
+	Comma-separated list of suffixes, which are used when searching for a
+	file for the "gf", "[I", etc. commands.  Example: >
+		:set suffixesadd=.java
+<
+				*'swapfile'* *'swf'* *'noswapfile'* *'noswf'*
+'swapfile' 'swf'	boolean (default on)
+			local to buffer
+	Use a swapfile for the buffer.  This option can be reset when a
+	swapfile is not wanted for a specific buffer.  For example, with
+	confidential information that even root must not be able to access.
+	Careful: All text will be in memory:
+		- Don't use this for big files.
+		- Recovery will be impossible!
+	A swapfile will only be present when |'updatecount'| is non-zero and
+	'swapfile' is set.
+	When 'swapfile' is reset, the swap file for the current buffer is
+	immediately deleted.  When 'swapfile' is set, and 'updatecount' is
+	non-zero, a swap file is immediately created.
+	Also see |swap-file| and |'swapsync'|.
+	If you want to open a new buffer without creating a swap file for it,
+	use the |:noswapfile| modifier.
+	See 'directory' for where the swap file is created.
+
+	This option is used together with 'bufhidden' and 'buftype' to
+	specify special kinds of buffers.   See |special-buffers|.
+
+						*'swapsync'* *'sws'*
+'swapsync' 'sws'	string	(default "fsync")
+			global
+	When this option is not empty a swap file is synced to disk after
+	writing to it.  This takes some time, especially on busy unix systems.
+	When this option is empty parts of the swap file may be in memory and
+	not written to disk.  When the system crashes you may lose more work.
+	On Unix the system does a sync now and then without Vim asking for it,
+	so the disadvantage of setting this option off is small.  On some
+	systems the swap file will not be written at all.  For a unix system
+	setting it to "sync" will use the sync() call instead of the default
+	fsync(), which may work better on some systems.
+	The 'fsync' option is used for the actual file.
+
+						*'switchbuf'* *'swb'*
+'switchbuf' 'swb'	string	(default "")
+			global
+	This option controls the behavior when switching between buffers.
+	This option is checked, when
+	- jumping to errors with the |quickfix| commands (|:cc|, |:cn|, |:cp|,
+	  etc.)
+	- jumping to a tag using the |:stag| command.
+	- opening a file using the |CTRL-W_f| or |CTRL-W_F| command.
+	- jumping to a buffer using a buffer split command (e.g.  |:sbuffer|,
+	  |:sbnext|, or |:sbrewind|).
+	Possible values (comma-separated list):
+	   useopen	If included, jump to the first open window in the
+			current tab page that contains the specified buffer
+			(if there is one).  Otherwise: Do not examine other
+			windows.
+	   usetab	Like "useopen", but also consider windows in other tab
+			pages.
+	   split	If included, split the current window before loading
+			a buffer for a |quickfix| command that display errors.
+			Otherwise: do not split, use current window (when used
+			in the quickfix window: the previously used window or
+			split if there is no other window).
+	   vsplit	Just like "split" but split vertically.
+	   newtab	Like "split", but open a new tab page.  Overrules
+			"split" when both are present.
+	   uselast	If included, jump to the previously used window when
+			jumping to errors with |quickfix| commands.
+
+						*'synmaxcol'* *'smc'*
+'synmaxcol' 'smc'	number	(default 3000)
+			local to buffer
+			{not available when compiled without the |+syntax|
+			feature}
+	Maximum column in which to search for syntax items.  In long lines the
+	text after this column is not highlighted and following lines may not
+	be highlighted correctly, because the syntax state is cleared.
+	This helps to avoid very slow redrawing for an XML file that is one
+	long line.
+	Set to zero to remove the limit.
+
+						*'syntax'* *'syn'*
+'syntax' 'syn'		string	(default empty)
+			local to buffer
+			{not available when compiled without the |+syntax|
+			feature}
+	When this option is set, the syntax with this name is loaded, unless
+	syntax highlighting has been switched off with ":syntax off".
+	Otherwise this option does not always reflect the current syntax (the
+	b:current_syntax variable does).
+	This option is most useful in a modeline, for a file which syntax is
+	not automatically recognized.  Example, in an IDL file:
+		/* vim: set syntax=idl : */ ~
+	When a dot appears in the value then this separates two filetype
+	names.  Example:
+		/* vim: set syntax=c.doxygen : */ ~
+	This will use the "c" syntax first, then the "doxygen" syntax.
+	Note that the second one must be prepared to be loaded as an addition,
+	otherwise it will be skipped.  More than one dot may appear.
+	To switch off syntax highlighting for the current file, use: >
+		:set syntax=OFF
+<	To switch syntax highlighting on according to the current value of the
+	'filetype' option: >
+		:set syntax=ON
+<	What actually happens when setting the 'syntax' option is that the
+	Syntax autocommand event is triggered with the value as argument.
+	This option is not copied to another buffer, independent of the 's' or
+	'S' flag in 'cpoptions'.
+	Only normal file name characters can be used, "/\*?[|<>" are illegal.
+
+						*'tabline'* *'tal'*
+'tabline' 'tal'		string	(default empty)
+			global
+	When non-empty, this option determines the content of the tab pages
+	line at the top of the Vim window.  When empty Vim will use a default
+	tab pages line.  See |setting-tabline| for more info.
+
+	The tab pages line only appears as specified with the 'showtabline'
+	option and only when there is no GUI tab line.  When 'e' is in
+	'guioptions' and the GUI supports a tab line 'guitablabel' is used
+	instead.  Note that the two tab pages lines are very different.
+
+	The value is evaluated like with 'statusline'.  You can use
+	|tabpagenr()|, |tabpagewinnr()| and |tabpagebuflist()| to figure out
+	the text to be displayed.  Use "%1T" for the first label, "%2T" for
+	the second one, etc.  Use "%X" items for closing labels.
+
+	When changing something that is used in 'tabline' that does not
+	trigger it to be updated, use |:redrawtabline|.
+	This option cannot be set in a modeline when 'modelineexpr' is off.
+
+	Keep in mind that only one of the tab pages is the current one, others
+	are invisible and you can't jump to their windows.
+
+
+						*'tabpagemax'* *'tpm'*
+'tabpagemax' 'tpm'	number	(default 10)
+			global
+	Maximum number of tab pages to be opened by the |-p| command line
+	argument or the ":tab all" command. |tabpage|
+
+
+						*'tabstop'* *'ts'*
+'tabstop' 'ts'		number	(default 8)
+			local to buffer
+	Number of spaces that a <Tab> in the file counts for.  Also see
+	the |:retab| command, and the 'softtabstop' option.
+
+	Note: Setting 'tabstop' to any other value than 8 can make your file
+	appear wrong in many places, e.g., when printing it.
+	The value must be more than 0 and less than 10000.
+
+	There are four main ways to use tabs in Vim:
+	1. Always keep 'tabstop' at 8, set 'softtabstop' and 'shiftwidth' to 4
+	   (or 3 or whatever you prefer) and use 'noexpandtab'.  Then Vim
+	   will use a mix of tabs and spaces, but typing <Tab> and <BS> will
+	   behave like a tab appears every 4 (or 3) characters.
+	   This is the recommended way, the file will look the same with other
+	   tools and when listing it in a terminal.
+	2. Set 'softtabstop' and 'shiftwidth' to whatever you prefer and use
+	   'expandtab'.  This way you will always insert spaces.  The
+	   formatting will never be messed up when 'tabstop' is changed (leave
+	   it at 8 just in case).  The file will be a bit larger.
+	   You do need to check if no Tabs exist in the file.  You can get rid
+	   of them by first setting 'expandtab' and using `%retab!`, making
+	   sure the value of 'tabstop' is set correctly.
+	3. Set 'tabstop' and 'shiftwidth' to whatever you prefer and use
+	   'expandtab'.  This way you will always insert spaces.  The
+	   formatting will never be messed up when 'tabstop' is changed.
+	   You do need to check if no Tabs exist in the file, just like in the
+	   item just above.
+	4. Set 'tabstop' and 'shiftwidth' to whatever you prefer and use a
+	   |modeline| to set these values when editing the file again.  Only
+	   works when using Vim to edit the file, other tools assume a tabstop
+	   is worth 8 spaces.
+	5. Always set 'tabstop' and 'shiftwidth' to the same value, and
+	   'noexpandtab'.  This should then work (for initial indents only)
+	   for any tabstop setting that people use.  It might be nice to have
+	   tabs after the first non-blank inserted as spaces if you do this
+	   though.  Otherwise aligned comments will be wrong when 'tabstop' is
+	   changed.
+
+	If Vim is compiled with the |+vartabs| feature then the value of
+	'tabstop' will be ignored if |'vartabstop'| is set to anything other
+	than an empty string.
+
+			*'tagbsearch'* *'tbs'* *'notagbsearch'* *'notbs'*
+'tagbsearch' 'tbs'	boolean	(default on)
+			global
+	When searching for a tag (e.g., for the |:ta| command), Vim can either
+	use a binary search or a linear search in a tags file.  Binary
+	searching makes searching for a tag a LOT faster, but a linear search
+	will find more tags if the tags file wasn't properly sorted.
+	Vim normally assumes that your tags files are sorted, or indicate that
+	they are not sorted.  Only when this is not the case does the
+	'tagbsearch' option need to be switched off.
+
+	When 'tagbsearch' is on, binary searching is first used in the tags
+	files.  In certain situations, Vim will do a linear search instead for
+	certain files, or retry all files with a linear search.  When
+	'tagbsearch' is off, only a linear search is done.
+
+	Linear searching is done anyway, for one file, when Vim finds a line
+	at the start of the file indicating that it's not sorted: >
+   !_TAG_FILE_SORTED	0	/some comment/
+<	[The whitespace before and after the '0' must be a single <Tab>]
+
+	When a binary search was done and no match was found in any of the
+	files listed in 'tags', and case is ignored or a pattern is used
+	instead of a normal tag name, a retry is done with a linear search.
+	Tags in unsorted tags files, and matches with different case will only
+	be found in the retry.
+
+	If a tag file indicates that it is case-fold sorted, the second,
+	linear search can be avoided when case is ignored.  Use a value of '2'
+	in the "!_TAG_FILE_SORTED" line for this.  A tag file can be case-fold
+	sorted with the -f switch to "sort" in most unices, as in the command:
+	"sort -f -o tags tags".  For Universal ctags and Exuberant ctags
+	version 5.x or higher (at least 5.5) the --sort=foldcase switch can be
+	used for this as well.  Note that case must be folded to uppercase for
+	this to work.
+
+	By default, tag searches are case-sensitive.  Case is ignored when
+	'ignorecase' is set and 'tagcase' is "followic", or when 'tagcase' is
+	"ignore".
+	Also when 'tagcase' is "followscs" and 'smartcase' is set, or
+	'tagcase' is "smart", and the pattern contains only lowercase
+	characters.
+
+	When 'tagbsearch' is off, tags searching is slower when a full match
+	exists, but faster when no full match exists.  Tags in unsorted tags
+	files may only be found with 'tagbsearch' off.
+	When the tags file is not sorted, or sorted in a wrong way (not on
+	ASCII byte value), 'tagbsearch' should be off, or the line given above
+	must be included in the tags file.
+	This option doesn't affect commands that find all matching tags (e.g.,
+	command-line completion and ":help").
+
+							*'tagcase'* *'tc'*
+'tagcase' 'tc'		string	(default "followic")
+			global or local to buffer |global-local|
+	This option specifies how case is handled when searching the tags
+	file:
+	   followic	Follow the 'ignorecase' option
+	   followscs    Follow the 'smartcase' and 'ignorecase' options
+	   ignore	Ignore case
+	   match	Match case
+	   smart	Ignore case unless an upper case letter is used
+	NOTE: This option is set to the Vi default value when 'compatible' is
+	set and to the Vim default value when 'compatible' is reset.
+
+							*'tagfunc'* *'tfu'*
+'tagfunc' 'tfu'		string	(default: empty)
+			local to buffer
+			{not available when compiled without the |+eval|
+			feature}
+	This option specifies a function to be used to perform tag searches.
+	The function gets the tag pattern and should return a List of matching
+	tags.  See |tag-function| for an explanation of how to write the
+	function and an example.  The value can be the name of a function, a
+	|lambda| or a |Funcref|. See |option-value-function| for more
+	information.
+
+						*'taglength'* *'tl'*
+'taglength' 'tl'	number	(default 0)
+			global
+	If non-zero, tags are significant up to this number of characters.
+
+			*'tagrelative'* *'tr'* *'notagrelative'* *'notr'*
+'tagrelative' 'tr'	boolean	(Vim default: on, Vi default: off)
+			global
+	If on and using a tags file in another directory, file names in that
+	tags file are relative to the directory where the tags file is.
+	NOTE: This option is set to the Vi default value when 'compatible' is
+	set and to the Vim default value when 'compatible' is reset.
+
+						*'tags'* *'tag'* *E433*
+'tags' 'tag'		string	(default "./tags,tags", when compiled with
+				|+emacs_tags|: "./tags,./TAGS,tags,TAGS")
+			global or local to buffer |global-local|
+	Filenames for the tag command, separated by spaces or commas.  To
+	include a space or comma in a file name, precede it with a backslash
+	(see |option-backslash| about including spaces and backslashes).
+	When a file name starts with "./", the '.' is replaced with the path
+	of the current file.  But only when the 'd' flag is not included in
+	'cpoptions'.  Environment variables are expanded |:set_env|.  Also see
+	|tags-option|.
+	"*", "**" and other wildcards can be used to search for tags files in
+	a directory tree.  See |file-searching|.  E.g., "/lib/**/tags" will
+	find all files named "tags" below "/lib".  The filename itself cannot
+	contain wildcards, it is used as-is.  E.g., "/lib/**/tags?" will find
+	files called "tags?".
+	The |tagfiles()| function can be used to get a list of the file names
+	actually used.
+	If Vim was compiled with the |+emacs_tags| feature, Emacs-style tag
+	files are also supported.  They are automatically recognized.  The
+	default value becomes "./tags,./TAGS,tags,TAGS", unless case
+	differences are ignored (MS-Windows).  |emacs-tags|
+	The use of |:set+=| and |:set-=| is preferred when adding or removing
+	file names from the list.  This avoids problems when a future version
+	uses another default.
+
+				*'tagstack'* *'tgst'* *'notagstack'* *'notgst'*
+'tagstack' 'tgst'	boolean	(default on)
+			global
+	When on, the |tagstack| is used normally.  When off, a ":tag" or
+	":tselect" command with an argument will not push the tag onto the
+	tagstack.  A following ":tag" without an argument, a ":pop" command or
+	any other command that uses the tagstack will use the unmodified
+	tagstack, but does change the pointer to the active entry.
+	Resetting this option is useful when using a ":tag" command in a
+	mapping which should not change the tagstack.
+
+						*'tcldll'*
+'tcldll'		string	(default depends on the build)
+			global
+			{only available when compiled with the |+tcl/dyn|
+			feature}
+	Specifies the name of the Tcl shared library. The default is
+	DYNAMIC_TCL_DLL, which was specified at compile time.
+	Environment variables are expanded |:set_env|.
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+						*'term'* *E529* *E530* *E531*
+'term'			string	(default is $TERM, if that fails:
+				      in the GUI: "builtin_gui"
+					on Amiga: "amiga"
+					on Haiku: "xterm"
+					  on Mac: "mac-ansi"
+					 on Unix: "ansi"
+					  on VMS: "ansi"
+				       on Win 32: "win32")
+			global
+	Name of the terminal.  Used for choosing the terminal control
+	characters.  Environment variables are expanded |:set_env|.
+	For example: >
+		:set term=$TERM
+<	See |termcap|.
+
+						*'termbidi'* *'tbidi'*
+						*'notermbidi'* *'notbidi'*
+'termbidi' 'tbidi'	boolean (default off, on for "mlterm")
+			global
+			{only available when compiled with the |+arabic|
+			feature}
+	The terminal is in charge of Bi-directionality of text (as specified
+	by Unicode).  The terminal is also expected to do the required shaping
+	that some languages (such as Arabic) require.
+	Setting this option implies that 'rightleft' will not be set when
+	'arabic' is set and the value of 'arabicshape' will be ignored.
+	Note that setting 'termbidi' has the immediate effect that
+	'arabicshape' is ignored, but 'rightleft' isn't changed automatically.
+	This option is reset when the GUI is started.
+	For further details see |arabic.txt|.
+
+					*'termencoding'* *'tenc'*
+'termencoding' 'tenc'	string	(default ""; with GTK+ GUI: "utf-8")
+			global
+	Encoding used for the terminal.  This specifies what character
+	encoding the keyboard produces and the display will understand.  For
+	the GUI it only applies to the keyboard ('encoding' is used for the
+	display).
+								*E617* *E950*
+	Note: This does not apply to the GTK+ GUI.  After the GUI has been
+	successfully initialized, 'termencoding' is forcibly set to "utf-8".
+	Any attempts to set a different value will be rejected, and an error
+	message is shown.
+	For the Win32 GUI and console versions 'termencoding' is not used,
+	because the Win32 system always passes Unicode characters.
+	When empty, the same encoding is used as for the 'encoding' option.
+	This is the normal value.
+	Not all combinations for 'termencoding' and 'encoding' are valid.  See
+	|encoding-table|.
+	The value for this option must be supported by internal conversions or
+	iconv().  When this is not possible no conversion will be done and you
+	will probably experience problems with non-ASCII characters.
+	Example: You are working with the locale set to euc-jp (Japanese) and
+	want to edit a UTF-8 file: >
+		:let &termencoding = &encoding
+		:set encoding=utf-8
+<	You need to do this when your system has no locale support for UTF-8.
+
+		*'termguicolors'* *'tgc'* *'notermguicolors'* *'notgc'* *E954*
+'termguicolors' 'tgc'	boolean (default off)
+			global
+			{not available when compiled without the
+			|+termguicolors| feature}
+	When on, uses |highlight-guifg| and |highlight-guibg| attributes in
+	the terminal (thus using 24-bit color).
+
+	Requires a ISO-8613-3 compatible terminal.  If setting this option
+	does not work (produces a colorless UI) reading |xterm-true-color|
+	might help.
+
+	For Win32 console, Windows 10 version 1703 (Creators Update) or later
+	is required. Use this check to find out: >
+		if has('vcon')
+<	This requires Vim to be built with the |+vtp| feature.
+
+	Note that the "cterm" attributes are still used, not the "gui" ones.
+
+	When using Vim with Windows Terminal, the background of Windows
+	Terminal is normally filled with the Vim background color.  Setting
+	'termguicolors' and the guibg of the Normal highlight group to NONE
+	will make the background transparent: >
+		:hi Normal guibg=NONE
+<
+	NOTE: This option is reset when 'compatible' is set.
+
+						*'termwinkey'* *'twk'*
+'termwinkey' 'twk'	string	(default "")
+			local to window
+	The key that starts a CTRL-W command in a terminal window.  Other keys
+	are sent to the job running in the window.
+	The <> notation can be used, e.g.: >
+		:set termwinkey=<C-L>
+<	The string must be one key stroke but can be multiple bytes.
+	When not set CTRL-W is used, so that CTRL-W : gets you to the command
+	line.  If 'termwinkey' is set to CTRL-L then CTRL-L : gets you to the
+	command line.
+
+						*'termwinscroll'* *'twsl'*
+'termwinscroll' 'twsl'	number	(default 10000)
+			local to buffer
+			{not available when compiled without the
+			|+terminal| feature}
+	Number of scrollback lines to keep.  When going over this limit the
+	first 10% of the scrollback lines are deleted.  This is just to reduce
+	the memory usage.  See |Terminal-Normal|.
+	Also used as a limit for text sent to the terminal in one write,
+	multiplied by the number of columns times 3 (average number of bytes
+	per cell).
+
+						*'termwinsize'* *'tws'*
+'termwinsize' 'tws'	string	(default "")
+			local to window
+	Size used when opening the |terminal| window.  Format:
+		{rows}x{columns} or {rows}*{columns}.
+	- When empty the terminal gets the size from the window.
+	- When set with a "x" (e.g., "24x80") the terminal size is not
+	  adjusted to the window size.  If the window is smaller only the
+	  top-left part is displayed.
+	- When set with a "*" (e.g., "10*50") the terminal size follows the
+	  window size, but will not be smaller than the specified rows and/or
+	  columns.
+	- When rows is zero then use the height of the window.
+	- When columns is zero then use the width of the window.
+	- Using "0x0" or "0*0" is the same as empty.
+	- Can be overruled in the |term_start()| options with "term_rows" and
+	  "term_cols".
+
+	Examples:
+	  "30x0" uses 30 rows and the current window width.
+	  "20*0" uses at least 20 rows and the current window width.
+	  "0*40" uses the current window height and at least 40 columns.
+	Note that the command running in the terminal window may still change
+	the size of the terminal.  In that case the Vim window will be
+	adjusted to that size, if possible.
+
+						*'termwintype'* *'twt'*
+'termwintype' 'twt'	string  (default "")
+			global
+			{only available when compiled with the |terminal|
+			feature on MS-Windows}
+	Specify the virtual console (pty) used when opening the terminal
+	window.
+
+	Possible values are:
+	    ""		use ConPTY if it is stable, winpty otherwise
+	    "winpty"	use winpty, fail if not supported
+	    "conpty"	use |ConPTY|, fail if not supported
+
+	|ConPTY| support depends on the platform.  Windows 10 October 2018
+	Update is the first version that supports ConPTY, however it is still
+	considered unstable.  ConPTY might become stable in the next release
+	of Windows 10.  winpty support needs to be installed.  If neither is
+	supported then you cannot open a terminal window.
+
+						*'terse'* *'noterse'*
+'terse'			boolean	(default off)
+			global
+	When set: Add 's' flag to 'shortmess' option (this makes the message
+	for a search that hits the start or end of the file not being
+	displayed).  When reset: Remove 's' flag from 'shortmess' option.  {Vi
+	shortens a lot of messages}

+	This option is obsolete.  Use 'fileformats'.
+	For backwards compatibility, when 'textauto' is set, 'fileformats' is
+	set to the default value for the current system.  When 'textauto' is
+	reset, 'fileformats' is made empty.
+	NOTE: This option is set to the Vi default value when 'compatible' is
+	set and to the Vim default value when 'compatible' is reset.
+
+				   *'textmode'* *'tx'* *'notextmode'* *'notx'*
+'textmode' 'tx'		boolean	(Win32: default on,
+				 others: default off)
+			local to buffer
+	This option is obsolete.  Use 'fileformat'.
+	For backwards compatibility, when 'textmode' is set, 'fileformat' is
+	set to "dos".  When 'textmode' is reset, 'fileformat' is set to
+	"unix".
+
+						*'textwidth'* *'tw'*
+'textwidth' 'tw'	number	(default 0)
+			local to buffer
+	Maximum width of text that is being inserted.  A longer line will be
+	broken after white space to get this width.  A zero value disables
+	this.
+	'textwidth' is set to 0 when the 'paste' option is set and restored
+	when 'paste' is reset.
+	When 'textwidth' is zero, 'wrapmargin' may be used.  See also
+	'formatoptions' and |ins-textwidth|.
+	When 'formatexpr' is set it will be used to break the line.
+	NOTE: This option is set to 0 when 'compatible' is set.
+
+						*'thesaurus'* *'tsr'*
+'thesaurus' 'tsr'	string	(default "")
+			global or local to buffer |global-local|
+	List of file names, separated by commas, that are used to lookup words
+	for thesaurus completion commands |i_CTRL-X_CTRL-T|.  See
+	|compl-thesaurus|.
+
+	This option is not used if 'thesaurusfunc' is set, either for the
+	buffer or globally.
+
+	To include a comma in a file name precede it with a backslash.  Spaces
+	after a comma are ignored, otherwise spaces are included in the file
+	name.  See |option-backslash| about using backslashes.  The use of
+	|:set+=| and |:set-=| is preferred when adding or removing directories
+	from the list.  This avoids problems when a future version uses
+	another default.  Backticks cannot be used in this option for security
+	reasons.
+
+						*'thesaurusfunc'* *'tsrfu'*
+'thesaurusfunc' 'tsrfu'	string	(default: empty)
+			global or local to buffer |global-local|
+			{not available when compiled without the |+eval|
+			feature}
+	This option specifies a function to be used for thesaurus completion
+	with CTRL-X CTRL-T. |i_CTRL-X_CTRL-T| See |compl-thesaurusfunc|.
+	The value can be the name of a function, a |lambda| or a |Funcref|.
+	See |option-value-function| for more information.
+
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+			     *'tildeop'* *'top'* *'notildeop'* *'notop'*
+'tildeop' 'top'		boolean	(default off)
+			global
+	When on: The tilde command "~" behaves like an operator.
+	NOTE: This option is reset when 'compatible' is set.
+
+				*'timeout'* *'to'* *'notimeout'* *'noto'*
+'timeout' 'to'		boolean (default on)
+			global
+						*'ttimeout'* *'nottimeout'*
+'ttimeout'		boolean (default off, set in |defaults.vim|)
+			global
+	These two options together determine the behavior when part of a
+	mapped key sequence or keyboard code has been received:
+
+	'timeout'    'ttimeout'		action	~
+	   off		off		do not time out
+	   on		on or off	time out on :mappings and key codes
+	   off		on		time out on key codes
+
+	If both options are off, Vim will wait until either the complete
+	mapping or key sequence has been received, or it is clear that there
+	is no mapping or key sequence for the received characters.  For
+	example: if you have mapped "vl" and Vim has received 'v', the next
+	character is needed to see if the 'v' is followed by an 'l'.
+	When one of the options is on, Vim will wait for about 1 second for
+	the next character to arrive.  After that the already received
+	characters are interpreted as single characters.  The waiting time can
+	be changed with the 'timeoutlen' option.
+	On slow terminals or very busy systems timing out may cause
+	malfunctioning cursor keys.  If both options are off, Vim waits
+	forever after an entered <Esc> if there are key codes that start
+	with <Esc>.  You will have to type <Esc> twice.  If you do not have
+	problems with key codes, but would like to have :mapped key
+	sequences not timing out in 1 second, set the 'ttimeout' option and
+	reset the 'timeout' option.
+
+	NOTE: 'ttimeout' is reset when 'compatible' is set.
+
+						*'timeoutlen'* *'tm'*
+'timeoutlen' 'tm'	number	(default 1000)
+			global
+
+						*'ttimeoutlen'* *'ttm'*
+'ttimeoutlen' 'ttm'	number	(default -1, set to 100 in |defaults.vim|)
+			global
+	The time in milliseconds that is waited for a key code or mapped key
+	sequence to complete.  Also used for CTRL-\ CTRL-N and CTRL-\ CTRL-G
+	when part of a command has been typed.
+	Normally only 'timeoutlen' is used and 'ttimeoutlen' is -1.  When a
+	different timeout value for key codes is desired set 'ttimeoutlen' to
+	a non-negative number.
+
+		ttimeoutlen	mapping delay	   key code delay	~
+		   < 0		'timeoutlen'	   'timeoutlen'
+		  >= 0		'timeoutlen'	   'ttimeoutlen'
+
+	The timeout only happens when the 'timeout' and 'ttimeout' options
+	tell so.  A useful setting would be >
+		:set timeout timeoutlen=3000 ttimeoutlen=100
+<	(time out on mapping after three seconds, time out on key codes after
+	a tenth of a second).
+
+						*'title'* *'notitle'*
+'title'			boolean	(default off, on when title can be restored)
+			global
+	When on, the title of the window will be set to the value of
+	'titlestring' (if it is not empty), or to:
+		filename [+=-] (path) - VIM
+	Where:
+		filename	the name of the file being edited
+		-		indicates the file cannot be modified, 'ma' off
+		+		indicates the file was modified
+		=		indicates the file is read-only
+		=+		indicates the file is read-only and modified
+		(path)		is the path of the file being edited
+		- VIM		the server name |v:servername| or "VIM"
+	Only works if the terminal supports setting window titles
+	(currently Amiga console, Win32 console, all GUI versions and
+	terminals with a non-empty 't_ts' option - these are Unix xterm and
+	iris-ansi by default, where 't_ts' is taken from the builtin termcap).
+								*X11*
+	When Vim was compiled with HAVE_X11 defined, the original title will
+	be restored if possible.  The output of ":version" will include "+X11"
+	when HAVE_X11 was defined, otherwise it will be "-X11".  This also
+	works for the icon name |'icon'|.
+	But: When Vim was started with the |-X| argument, restoring the title
+	will not work (except in the GUI).
+	If the title cannot be restored, it is set to the value of 'titleold'.
+	You might want to restore the title outside of Vim then.
+	When using an xterm from a remote machine you can use this command:
+	    rsh machine_name xterm -display $DISPLAY &
+	then the WINDOWID environment variable should be inherited and the
+	title of the window should change back to what it should be after
+	exiting Vim.
+
+								*'titlelen'*
+'titlelen'		number	(default 85)
+			global
+	Gives the percentage of 'columns' to use for the length of the window
+	title.  When the title is longer, only the end of the path name is
+	shown.  A '<' character before the path name is used to indicate this.
+	Using a percentage makes this adapt to the width of the window.  But
+	it won't work perfectly, because the actual number of characters
+	available also depends on the font used and other things in the title
+	bar.  When 'titlelen' is zero the full path is used.  Otherwise,
+	values from 1 to 30000 percent can be used.
+	'titlelen' is also used for the 'titlestring' option.
+
+						*'titleold'*
+'titleold'		string	(default "Thanks for flying Vim")
+			global
+	This option will be used for the window title when exiting Vim if the
+	original title cannot be restored.  Only happens if 'title' is on or
+	'titlestring' is not empty.
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+						*'titlestring'*
+'titlestring'		string	(default "")
+			global
+	When this option is not empty, it will be used for the title of the
+	window.  This happens only when the 'title' option is on.
+	Only works if the terminal supports setting window titles (currently
+	Amiga console, Win32 console, all GUI versions and terminals with a
+	non-empty 't_ts' option).
+	When Vim was compiled with HAVE_X11 defined, the original title will
+	be restored if possible, see |X11|.
+
+	When this option contains printf-style '%' items, they will be
+	expanded according to the rules used for 'statusline'.
+	This option cannot be set in a modeline when 'modelineexpr' is off.
+
+	Example: >
+    :auto BufEnter * let &titlestring = hostname() .. "/" .. expand("%:p")
+    :set title titlestring=%<%F%=%l/%L-%P titlelen=70
+<	The value of 'titlelen' is used to align items in the middle or right
+	of the available space.
+	Some people prefer to have the file name first: >
+    :set titlestring=%t%(\ %M%)%(\ (%{expand(\"%:~:.:h\")})%)%(\ %a%)
+<	Note the use of "%{ }" and an expression to get the path of the file,
+	without the file name.  The "%( %)" constructs are used to add a
+	separating space only when needed.
+	NOTE: Use of special characters in 'titlestring' may cause the display
+	to be garbled (e.g., when it contains a CR or NL character).
+	{not available when compiled without the |+statusline| feature}
+
+				*'toolbar'* *'tb'*
+'toolbar' 'tb'		string	(default "icons,tooltips")
+			global
+			{only for |+GUI_GTK|, |+GUI_Motif| and |+GUI_Photon|}
+	The contents of this option controls various toolbar settings.  The
+	possible values are:
+		icons		Toolbar buttons are shown with icons.
+		text		Toolbar buttons shown with text.
+		horiz		Icon and text of a toolbar button are
+				horizontally arranged.  {only in GTK+ 2 GUI}
+		tooltips	Tooltips are active for toolbar buttons.
+	Tooltips refer to the popup help text which appears after the mouse
+	cursor is placed over a toolbar button for a brief moment.
+
+	If you want the toolbar to be shown with icons as well as text, do the
+	following: >
+		:set tb=icons,text
+<	Motif cannot display icons and text at the same time.  They
+	will show icons if both are requested.
+
+	If none of the strings specified in 'toolbar' are valid or if
+	'toolbar' is empty, this option is ignored.  If you want to disable
+	the toolbar, you need to set the 'guioptions' option.  For example: >
+		:set guioptions-=T
+<	Also see |gui-toolbar|.
+
+						*'toolbariconsize'* *'tbis'*
+'toolbariconsize' 'tbis'	string	(default "small")
+				global
+				{only in the GTK+ GUI}
+	Controls the size of toolbar icons.  The possible values are:
+		tiny		Use tiny icons.
+		small		Use small icons (default).
+		medium		Use medium-sized icons.
+		large		Use large icons.
+		huge		Use even larger icons.
+		giant		Use very big icons.
+	The exact dimensions in pixels of the various icon sizes depend on
+	the current theme.  Common dimensions are giant=48x48, huge=32x32,
+	large=24x24, medium=24x24, small=20x20 and tiny=16x16.
+
+	If 'toolbariconsize' is empty, the global default size as determined
+	by user preferences or the current theme is used.
+
+			     *'ttybuiltin'* *'tbi'* *'nottybuiltin'* *'notbi'*
+'ttybuiltin' 'tbi'	boolean	(default on)
+			global
+	When on, the builtin termcaps are searched before the external ones.
+	When off the builtin termcaps are searched after the external ones.
+	When this option is changed, you should set the 'term' option next for
+	the change to take effect, for example: >
+		:set notbi term=$TERM
+<	See also |termcap|.
+	Rationale: The default for this option is "on", because the builtin
+	termcap entries are generally better (many systems contain faulty
+	xterm entries...).
+
+				     *'ttyfast'* *'tf'* *'nottyfast'* *'notf'*
+'ttyfast' 'tf'		boolean	(default on)
+			global
+	Indicates a fast terminal connection.  More characters will be sent to
+	the screen for redrawing, instead of using insert/delete line
+	commands.  Improves smoothness of redrawing when there are multiple
+	windows and the terminal does not support a scrolling region.
+	Also enables the extra writing of characters at the end of each screen
+	line for lines that wrap.  This helps when using copy/paste with the
+	mouse in an xterm and other terminals.
+
+	The default used to be set only for some terminal names, but these
+	days nearly all terminals are fast, therefore the default is now "on".
+	If you have a slow connection you may want to set this option off,
+	e.g. depending on the host name: >
+		if hostname() =~ 'faraway'
+		   set nottyfast
+		endif
+<
+						*'ttymouse'* *'ttym'*
+'ttymouse' 'ttym'	string	(default depends on 'term')
+			global
+			{only in Unix and VMS, doesn't work in the GUI; not
+			available when compiled without |+mouse|}
+	Name of the terminal type for which mouse codes are to be recognized.
+	Currently these strings are valid:
+							*xterm-mouse*
+	   xterm	xterm-like mouse handling.  The mouse generates
+			"<Esc>[Mscr", where "scr" is three bytes:
+				"s"  = button state
+				"c"  = column plus 33
+				"r"  = row plus 33
+			This only works up to 223 columns!  See "dec",
+			"urxvt", and "sgr" for solutions.
+	   xterm2	Works like "xterm", but with the xterm reporting the
+			mouse position while the mouse is dragged.  This works
+			much faster and more precise.  Your xterm must at
+			least at patchlevel 88 / XFree 3.3.3 for this to
+			work.  See below for how Vim detects this
+			automatically.
+							*netterm-mouse*
+	   netterm	NetTerm mouse handling.  A left mouse click generates
+			"<Esc>}r,c<CR>", where "r,c" are two decimal numbers
+			for the row and column.  No other mouse events are
+			supported.
+							*dec-mouse*
+	   dec		DEC terminal mouse handling.  The mouse generates a
+			rather complex sequence, starting with "<Esc>[".
+			This is also available for an Xterm, if it was
+			configured with "--enable-dec-locator".
+							*jsbterm-mouse*
+	   jsbterm	JSB term mouse handling.
+							*pterm-mouse*
+	   pterm	QNX pterm mouse handling.
+							*urxvt-mouse*
+	   urxvt	Mouse handling for the urxvt (rxvt-unicode) terminal.
+			The mouse works only if the terminal supports this
+			encoding style, but it does not have 223 columns limit
+			unlike "xterm" or "xterm2".
+							*sgr-mouse*
+	   sgr		Mouse handling for the terminal that emits SGR-styled
+			mouse reporting.  The mouse works even in columns
+			beyond 223.  This option is backward compatible with
+			"xterm2" because it can also decode "xterm2" style
+			mouse codes.
+
+	The mouse handling must be enabled at compile time |+mouse_xterm|
+	|+mouse_dec| |+mouse_netterm| |+mouse_jsbterm| |+mouse_urxvt|
+	|+mouse_sgr|.
+	Only "xterm"(2) is really recognized.  NetTerm mouse codes are always
+	recognized, if enabled at compile time.  DEC terminal mouse codes
+	are recognized if enabled at compile time, and 'ttymouse' is not
+	"xterm", "xterm2", "urxvt" or "sgr" (because dec mouse codes conflict
+	with them).
+	This option is automatically set to "xterm", when the 'term' option is
+	set to a name that starts with "xterm", "mlterm", "screen", "tmux",
+	"st" (full match only), "st-" or "stterm", and 'ttymouse' is not set
+	already.
+	If the terminfo/termcap entry "XM" exists and the first number is
+	"1006" then 'ttymouse' will be set to "sgr".  This works for many
+	modern terminals.
+	Additionally, if vim is compiled with the |+termresponse| feature and
+	|t_RV| is set to the escape sequence to request the xterm version
+	number, more intelligent detection is done.
+	The "xterm2" value will be set if the xterm version is reported to be
+	from 95 to 276.  The "sgr" value will be set if Vim detects Mac
+	Terminal.app, iTerm2 or mintty, and when the xterm version is 277 or
+	higher.
+	If you do not want 'ttymouse' to be set to "xterm2" or "sgr"
+	automatically, set t_RV to an empty string: >
+		:set t_RV=
+<
+						*'ttyscroll'* *'tsl'*
+'ttyscroll' 'tsl'	number	(default 999)
+			global
+	Maximum number of lines to scroll the screen.  If there are more lines
+	to scroll the window is redrawn.  For terminals where scrolling is
+	very slow and redrawing is not slow this can be set to a small number,
+	e.g., 3, to speed up displaying.
+
+						*'ttytype'* *'tty'*
+'ttytype' 'tty'		string	(default from $TERM)
+			global
+	Alias for 'term', see above.
+
+						*'undodir'* *'udir'*
+'undodir' 'udir'	string	(default ".")
+			global
+			{only when compiled with the |+persistent_undo| feature}
+	List of directory names for undo files, separated with commas.
+	See |'backupdir'| for details of the format.
+	"." means using the directory of the file.  The undo file name for
+	"file.txt" is ".file.txt.un~".
+	For other directories the file name is the full path of the edited
+	file, with path separators replaced with "%".
+	When writing: The first directory that exists is used. "." always
+	works, no directories after "." will be used for writing.
+	When reading all entries are tried to find an undo file.  The first
+	undo file that exists is used.  When it cannot be read an error is
+	given, no further entry is used.
+	See |undo-persistence|.
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+				*'undofile'* *'noundofile'* *'udf'* *'noudf'*
+'undofile' 'udf'	boolean	(default off)
+			local to buffer
+			{only when compiled with the |+persistent_undo| feature}
+	When on, Vim automatically saves undo history to an undo file when
+	writing a buffer to a file, and restores undo history from the same
+	file on buffer read.
+	The directory where the undo file is stored is specified by 'undodir'.
+	For more information about this feature see |undo-persistence|.
+	The undo file is not read when 'undoreload' causes the buffer from
+	before a reload to be saved for undo.
+	When 'undofile' is turned off the undo file is NOT deleted.
+	NOTE: This option is reset when 'compatible' is set.
+
+						*'undolevels'* *'ul'*
+'undolevels' 'ul'	number	(default 100, 1000 for Unix, VMS and Win32)
+			global or local to buffer |global-local|
+	Maximum number of changes that can be undone.  Since undo information
+	is kept in memory, higher numbers will cause more memory to be used.
+	Nevertheless, a single change can already use a large amount of memory.
+	Set to 0 for Vi compatibility: One level of undo and "u" undoes
+	itself: >
+		set ul=0
+<	But you can also get Vi compatibility by including the 'u' flag in
+	'cpoptions', and still be able to use CTRL-R to repeat undo.
+	Also see |undo-two-ways|.
+	Set to -1 for no undo at all.  You might want to do this only for the
+	current buffer: >
+		setlocal ul=-1
+<	This helps when you run out of memory for a single change.
+
+	The local value is set to -123456 when the global value is to be used.
+
+	Also see |clear-undo|.
+
+						*'undoreload'* *'ur'*
+'undoreload' 'ur'	number	(default 10000)
+			global
+	Save the whole buffer for undo when reloading it.  This applies to the
+	":e!" command and reloading for when the buffer changed outside of
+	Vim. |FileChangedShell|
+	The save only happens when this option is negative or when the number
+	of lines is smaller than the value of this option.
+	Set this option to zero to disable undo for a reload.
+
+	When saving undo for a reload, any undo file is not read.
+
+	Note that this causes the whole buffer to be stored in memory.  Set
+	this option to a lower value if you run out of memory.
+
+						*'updatecount'* *'uc'*
+'updatecount' 'uc'	number	(default: 200)
+			global
+	After typing this many characters the swap file will be written to
+	disk.  When zero, no swap file will be created at all (see chapter on
+	recovery |crash-recovery|).  'updatecount' is set to zero by starting
+	Vim with the "-n" option, see |startup|.  When editing in readonly
+	mode this option will be initialized to 10000.
+	The swapfile can be disabled per buffer with |'swapfile'|.
+	When 'updatecount' is set from zero to non-zero, swap files are
+	created for all buffers that have 'swapfile' set.  When 'updatecount'
+	is set to zero, existing swap files are not deleted.
+	Also see |'swapsync'|.
+	This option has no meaning in buffers where |'buftype'| is "nofile"
+	or "nowrite".
+
+						*'updatetime'* *'ut'*
+'updatetime' 'ut'	number	(default 4000)
+			global
+	If this many milliseconds nothing is typed the swap file will be
+	written to disk (see |crash-recovery|).  Also used for the
+	|CursorHold| autocommand event.
+
+					*'varsofttabstop'* *'vsts'*
+'varsofttabstop' 'vsts'	string	(default "")
+			local to buffer
+			{only available when compiled with the |+vartabs|
+			feature}
+	A list of the number of spaces that a <Tab> counts for while editing,
+	such as inserting a <Tab> or using <BS>.  It "feels" like variable-
+	width <Tab>s are being inserted, while in fact a mixture of spaces
+	and <Tab>s is used.  Tab widths are separated with commas, with the
+	final value applying to all subsequent tabs.
+
+	For example, when editing assembly language files where statements
+	start in the 9th column and comments in the 41st, it may be useful
+	to use the following: >
+		:set varsofttabstop=8,32,8
+<	This will set soft tabstops with 8 and 8 + 32 spaces, and 8 more
+	for every column thereafter.
+
+	Note that the value of |'softtabstop'| will be ignored while
+	'varsofttabstop' is set.
+
+						*'vartabstop'* *'vts'*
+'vartabstop' 'vts'	string	(default "")
+			local to buffer
+			{only available when compiled with the |+vartabs|
+			feature}
+	A list of the number of spaces that a <Tab> in the file counts for,
+	separated by commas.  Each value corresponds to one tab, with the
+	final value applying to all subsequent tabs. For example: >
+		:set vartabstop=4,20,10,8
+<	This will make the first tab 4 spaces wide, the second 20 spaces,
+	the third 10 spaces, and all following tabs 8 spaces.
+
+	Note that the value of |'tabstop'| will be ignored while 'vartabstop'
+	is set.
+
+						*'verbose'* *'vbs'*
+'verbose' 'vbs'		number	(default 0)
+			global
+	When bigger than zero, Vim will give messages about what it is doing.
+	Currently, these messages are given:
+	>= 1	When the viminfo file is read or written.
+	>= 2	When a file is ":source"'ed.
+	>= 4	Shell commands.
+	>= 5	Every searched tags file and include file.
+	>= 8	Files for which a group of autocommands is executed.
+	>= 9	Every executed autocommand.
+	>= 11	Finding items in a path
+	>= 12	Every executed function.
+	>= 13	When an exception is thrown, caught, finished, or discarded.
+	>= 14	Anything pending in a ":finally" clause.
+	>= 15	Every executed Ex command from a script (truncated at 200
+		characters).
+	>= 16	Every executed Ex command.
+
+	This option can also be set with the "-V" argument.  See |-V|.
+	This option is also set by the |:verbose| command.
+
+	When the 'verbosefile' option is set then the verbose messages are not
+	displayed.
+
+						*'verbosefile'* *'vfile'*
+'verbosefile' 'vfile'	string	(default empty)
+			global
+	When not empty all messages are written in a file with this name.
+	When the file exists messages are appended.
+	Writing to the file ends when Vim exits or when 'verbosefile' is made
+	empty.  Writes are buffered, thus may not show up for some time.
+	Setting 'verbosefile' to a new value is like making it empty first.
+	The difference with |:redir| is that verbose messages are not
+	displayed when 'verbosefile' is set.
+
+						*'viewdir'* *'vdir'*
+'viewdir' 'vdir'	string	(default for Amiga "home:vimfiles/view",
+					 for Win32: "$HOME/vimfiles/view",
+					 for Unix: "$HOME/.vim/view",
+					 for macOS: "$VIM/vimfiles/view"
+					 for VMS: "sys$login:vimfiles/view")
+			global
+			{not available when compiled without the |+mksession|
+			feature}
+	Name of the directory where to store files for |:mkview|.
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+						*'viewoptions'* *'vop'*
+'viewoptions' 'vop'	string	(default: "folds,options,cursor,curdir")
+			global
+			{not available when compiled without the |+mksession|
+			feature}
+	Changes the effect of the |:mkview| command.  It is a comma-separated
+	list of words.  Each word enables saving and restoring something:
+	   word		save and restore ~
+	   cursor	cursor position in file and in window
+	   folds	manually created folds, opened/closed folds and local
+			fold options
+	   options	options and mappings local to a window or buffer (not
+			global values for local options)
+	   localoptions same as "options"
+	   slash	backslashes in file names replaced with forward
+			slashes
+	   unix		with Unix end-of-line format (single <NL>), even when
+			on MS-Windows
+	   curdir	the window-local directory, if set with `:lcd`
+
+	"slash" and "unix" are useful on MS-Windows when sharing view files
+	with Unix.  The Unix version of Vim cannot source dos format scripts,
+	but the MS-Windows version of Vim can source unix format scripts.

+				*'viminfo'* *'vi'* *E526* *E527* *E528*
+'viminfo' 'vi'		string	(Vi default: "", Vim default for
+				   MS-Windows: '100,<50,s10,h,rA:,rB:,
+				   for Amiga: '100,<50,s10,h,rdf0:,rdf1:,rdf2:
+				   for others: '100,<50,s10,h)
+			global
+			{not available when compiled without the |+viminfo|
+			feature}
+	When non-empty, the viminfo file is read upon startup and written
+	when exiting Vim (see |viminfo-file|). Except when 'viminfofile' is
+	"NONE".
+	The string should be a comma-separated list of parameters, each
+	consisting of a single character identifying the particular parameter,
+	followed by a number or string which specifies the value of that
+	parameter.  If a particular character is left out, then the default
+	value is used for that parameter.  The following is a list of the
+	identifying characters and the effect of their value.
+	CHAR	VALUE	~
+							*viminfo-!*
+	!	When included, save and restore global variables that start
+		with an uppercase letter, and don't contain a lowercase
+		letter.  Thus "KEEPTHIS and "K_L_M" are stored, but "KeepThis"
+		and "_K_L_M" are not.  Nested List and Dict items may not be
+		read back correctly, you end up with an empty item.
+							*viminfo-quote*
+	"	Maximum number of lines saved for each register.  Old name of
+		the '<' item, with the disadvantage that you need to put a
+		backslash before the ", otherwise it will be recognized as the
+		start of a comment!
+							*viminfo-%*
+	%	When included, save and restore the buffer list.  If Vim is
+		started with a file name argument, the buffer list is not
+		restored.  If Vim is started without a file name argument, the
+		buffer list is restored from the viminfo file.  Quickfix
+		('buftype'), unlisted ('buflisted'), unnamed and buffers on
+		removable media (|viminfo-r|) are not saved.
+		When followed by a number, the number specifies the maximum
+		number of buffers that are stored.  Without a number all
+		buffers are stored.
+							*viminfo-'*
+	'	Maximum number of previously edited files for which the marks
+		are remembered.  This parameter must always be included when
+		'viminfo' is non-empty.
+		Including this item also means that the |jumplist| and the
+		|changelist| are stored in the viminfo file.
+							*viminfo-/*
+	/	Maximum number of items in the search pattern history to be
+		saved.  If non-zero, then the previous search and substitute
+		patterns are also saved.  When not included, the value of
+		'history' is used.
+							*viminfo-:*
+	:	Maximum number of items in the command-line history to be
+		saved.  When not included, the value of 'history' is used.
+							*viminfo-<*
+	<	Maximum number of lines saved for each register.  If zero then
+		registers are not saved.  When not included, all lines are
+		saved.  '"' is the old name for this item.
+		Also see the 's' item below: limit specified in Kbyte.
+							*viminfo-@*
+	@	Maximum number of items in the input-line history to be
+		saved.  When not included, the value of 'history' is used.
+							*viminfo-c*
+	c	When included, convert the text in the viminfo file from the
+		'encoding' used when writing the file to the current
+		'encoding'.  See |viminfo-encoding|.
+							*viminfo-f*
+	f	Whether file marks need to be stored.  If zero, file marks ('0
+		to '9, 'A to 'Z) are not stored.  When not present or when
+		non-zero, they are all stored.  '0 is used for the current
+		cursor position (when exiting or when doing ":wviminfo").
+							*viminfo-h*
+	h	Disable the effect of 'hlsearch' when loading the viminfo
+		file.  When not included, it depends on whether ":nohlsearch"
+		has been used since the last search command.
+							*viminfo-n*
+	n	Name of the viminfo file.  The name must immediately follow
+		the 'n'.  Must be at the end of the option!  If the
+		'viminfofile' option is set, that file name overrides the one
+		given here with 'viminfo'.  Environment variables are
+		expanded when opening the file, not when setting the option.
+							*viminfo-r*
+	r	Removable media.  The argument is a string (up to the next
+		',').  This parameter can be given several times.  Each
+		specifies the start of a path for which no marks will be
+		stored.  This is to avoid removable media.  For MS-Windows you
+		could use "ra:,rb:", for Amiga "rdf0:,rdf1:,rdf2:".  You can
+		also use it for temp files, e.g., for Unix: "r/tmp".  Case is
+		ignored.  Maximum length of each 'r' argument is 50
+		characters.
+							*viminfo-s*
+	s	Maximum size of an item in Kbyte.  If zero then registers are
+		not saved.  Currently only applies to registers.  The default
+		"s10" will exclude registers with more than 10 Kbyte of text.
+		Also see the '<' item above: line count limit.
+
+	Example: >
+	    :set viminfo='50,<1000,s100,:0,n~/vim/viminfo
+<
+	'50		Marks will be remembered for the last 50 files you
+			edited.
+	<1000		Contents of registers (up to 1000 lines each) will be
+			remembered.
+	s100		Registers with more than 100 Kbyte text are skipped.
+	:0		Command-line history will not be saved.
+	n~/vim/viminfo	The name of the file to use is "~/vim/viminfo".
+	no /		Since '/' is not specified, the default will be used,
+			that is, save all of the search history, and also the
+			previous search and substitute patterns.
+	no %		The buffer list will not be saved nor read back.
+	no h		'hlsearch' highlighting will be restored.
+
+	When setting 'viminfo' from an empty value you can use |:rviminfo| to
+	load the contents of the file, this is not done automatically.
+
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+	NOTE: This option is set to the Vim default value when 'compatible'
+	is reset.
+
+				*'viminfofile'* *'vif'*
+'viminfofile' 'vif'	string	(default: "")
+			global
+			{not available when compiled without the |+viminfo|
+			feature}
+	When non-empty, overrides the file name used for viminfo.
+	When equal to "NONE" no viminfo file will be read or written.
+	This option can be set with the |-i| command line flag.  The |--clean|
+	command line flag sets it to "NONE".
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+					    *'virtualedit'* *'ve'*
+'virtualedit' 've'	string	(default "")
+			global or local to window |global-local|
+	A comma-separated list of these words:
+	    block	Allow virtual editing in Visual block mode.
+	    insert	Allow virtual editing in Insert mode.
+	    all		Allow virtual editing in all modes.
+	    onemore	Allow the cursor to move just past the end of the line
+	    none	When used as the local value, do not allow virtual
+			editing even when the global value is set.  When used
+			as the global value, "none" is the same as "".
+	    NONE	Alternative spelling of "none".
+
+	Virtual editing means that the cursor can be positioned where there is
+	no actual character.  This can be halfway into a tab or beyond the end
+	of the line.  Useful for selecting a rectangle in Visual mode and
+	editing a table.
+	"onemore" is not the same, it will only allow moving the cursor just
+	after the last character of the line.  This makes some commands more
+	consistent.  Previously the cursor was always past the end of the line
+	if the line was empty.  But it is far from Vi compatible.  It may also
+	break some plugins or Vim scripts.  For example because |l| can move
+	the cursor after the last character.  Use with care!
+	Using the `$` command will move to the last character in the line, not
+	past it.  This may actually move the cursor to the left!
+	The `g$` command will move to the end of the screen line.
+	It doesn't make sense to combine "all" with "onemore", but you will
+	not get a warning for it.
+	When combined with other words, "none" is ignored.
+	NOTE: This option is set to "" when 'compatible' is set.
+
+			*'visualbell'* *'vb'* *'novisualbell'* *'novb'* *beep*
+'visualbell' 'vb'	boolean	(default off)
+			global
+	Use a visual bell instead of beeping.  The terminal code to display the
+	visual bell is given with 't_vb'.  When no beep or flash is wanted,
+	use: >
+		:set vb t_vb=
+<	If you want a short flash, you can use this on many terminals: >
+		:set vb t_vb=[?5h$<100>[?5l
+<	Here $<100> specifies the time, you can use a smaller or bigger value
+	to get a shorter or longer flash.
+
+	Note: Vim will limit the bell to once per half a second.  This avoids
+	having to wait for the flashing to finish when there are lots of
+	bells, e.g. on key repeat.  This also happens without 'visualbell'
+	set.
+
+	In the GUI, 't_vb' defaults to "<Esc>|f", which inverts the display
+	for 20 msec.  If you want to use a different time, use "<Esc>|40f",
+	where 40 is the time in msec.
+
+	Note: When the GUI starts, 't_vb' is reset to its default value.  You
+	might want to set it again in your |gvimrc|.
+
+	Does not work on the Amiga, you always get a screen flash.
+	Also see 'errorbells'.
+
+						*'warn'* *'nowarn'*
+'warn'			boolean	(default on)
+			global
+	Give a warning message when a shell command is used while the buffer
+	has been changed.
+
+		     *'weirdinvert'* *'wiv'* *'noweirdinvert'* *'nowiv'*
+'weirdinvert' 'wiv'	boolean	(default off)
+			global
+	This option has the same effect as the 't_xs' terminal option.
+	It is provided for backwards compatibility with version 4.x.
+	Setting 'weirdinvert' has the effect of making 't_xs' non-empty, and
+	vice versa.  Has no effect when the GUI is running.
+
+						*'whichwrap'* *'ww'*
+'whichwrap' 'ww'	string	(Vim default: "b,s", Vi default: "")
+			global
+	Allow specified keys that move the cursor left/right to move to the
+	previous/next line when the cursor is on the first/last character in
+	the line.  Concatenate characters to allow this for these keys:
+		char   key	  mode	~
+		 b    <BS>	 Normal and Visual
+		 s    <Space>	 Normal and Visual
+		 h    "h"	 Normal and Visual (not recommended)
+		 l    "l"	 Normal and Visual (not recommended)
+		 <    <Left>	 Normal and Visual
+		 >    <Right>	 Normal and Visual
+		 ~    "~"	 Normal
+		 [    <Left>	 Insert and Replace
+		 ]    <Right>	 Insert and Replace
+	For example: >
+		:set ww=<,>,[,]
+<	allows wrap only when cursor keys are used.
+	When the movement keys are used in combination with a delete or change
+	operator, the <EOL> also counts for a character.  This makes "3h"
+	different from "3dh" when the cursor crosses the end of a line.  This
+	is also true for "x" and "X", because they do the same as "dl" and
+	"dh".  If you use this, you may also want to use the mapping
+	":map <BS> X" to make backspace delete the character in front of the
+	cursor.
+	When 'l' is included and it is used after an operator at the end of a
+	line (not an empty line) then it will not move to the next line.  This
+	makes "dl", "cl", "yl" etc. work normally.
+	NOTE: This option is set to the Vi default value when 'compatible' is
+	set and to the Vim default value when 'compatible' is reset.
+
+						*'wildchar'* *'wc'*
+'wildchar' 'wc'		number	(Vim default: <Tab>, Vi default: CTRL-E)
+			global
+	Character you have to type to start wildcard expansion in the
+	command-line, as specified with 'wildmode'.
+	More info here: |cmdline-completion|.
+	The character is not recognized when used inside a macro.  See
+	'wildcharm' for that.
+	Some keys will not work, such as CTRL-C, <CR> and Enter.
+	Although 'wc' is a number option, you can set it to a special key: >
+		:set wc=<Tab>
+<	NOTE: This option is set to the Vi default value when 'compatible' is
+	set and to the Vim default value when 'compatible' is reset.
+
+						*'wildcharm'* *'wcm'*
+'wildcharm' 'wcm'	number	(default: none (0))
+			global
+	'wildcharm' works exactly like 'wildchar', except that it is
+	recognized when used inside a macro.  You can find "spare" command-line
+	keys suitable for this option by looking at |ex-edit-index|.  Normally
+	you'll never actually type 'wildcharm', just use it in mappings that
+	automatically invoke completion mode, e.g.: >
+		:set wcm=<C-Z>
+		:cnoremap ss so $vim/sessions/*.vim<C-Z>
+<	Then after typing :ss you can use CTRL-P & CTRL-N.
+
+						*'wildignore'* *'wig'*
+'wildignore' 'wig'	string	(default "")
+			global
+	A list of file patterns.  A file that matches with one of these
+	patterns is ignored when expanding |wildcards|, completing file or
+	directory names, and influences the result of |expand()|, |glob()| and
+	|globpath()| unless a flag is passed to disable this.
+	The pattern is used like with |:autocmd|, see |autocmd-patterns|.
+	Also see 'suffixes'.
+	Example: >
+		:set wildignore=*.o,*.obj
+<	The use of |:set+=| and |:set-=| is preferred when adding or removing
+	a pattern from the list.  This avoids problems when a future version
+	uses another default.
+
+
+			*'wildignorecase'* *'wic'* *'nowildignorecase'* *'nowic'*
+'wildignorecase' 'wic'	boolean	(default off)
+			global
+	When set case is ignored when completing file names and directories.
+	Has no effect when 'fileignorecase' is set.
+	Does not apply when the shell is used to expand wildcards, which
+	happens when there are special characters.
+
+
+				*'wildmenu'* *'wmnu'* *'nowildmenu'* *'nowmnu'*
+'wildmenu' 'wmnu'	boolean	(default off, set in |defaults.vim|)
+			global
+	When 'wildmenu' is on, command-line completion operates in an enhanced
+	mode.  On pressing 'wildchar' (usually <Tab>) to invoke completion,
+	the possible matches are shown.
+	When 'wildoptions' contains "pum", then the completion matches are
+	shown in a popup menu.  Otherwise they are displayed just above the
+	command line, with the first match highlighted (overwriting the status
+	line, if there is one).
+	Keys that show the previous/next match, such as <Tab> or
+	CTRL-P/CTRL-N, cause the highlight to move to the appropriate match.
+	When 'wildmode' is used, "wildmenu" mode is used where "full" is
+	specified.  "longest" and "list" do not start "wildmenu" mode.
+	You can check the current mode with |wildmenumode()|.
+	If there are more matches than can fit in the line, a ">" is shown on
+	the right and/or a "<" is shown on the left.  The status line scrolls
+	as needed.
+	The "wildmenu" mode is abandoned when a key is hit that is not used
+	for selecting a completion.
+	While the "wildmenu" is active, not using the popup menu, the
+	following keys have special meanings:
+
+	<Left> <Right>	- select previous/next match (like CTRL-P/CTRL-N)
+	<Down>		- in filename/menu name completion: move into a
+			  subdirectory or submenu.
+	<CR>		- in menu completion, when the cursor is just after a
+			  dot: move into a submenu.
+	<Up>		- in filename/menu name completion: move up into
+			  parent directory or parent menu.
+
+	When using the popup menu for command line completion, the following
+	keys have special meanings:
+	<Down>		- select next match (like CTRL-N)
+	<Left>		- in filename/menu name completion: move up into
+			  parent directory or parent menu.
+	<Right>		- in filename/menu name completion: move into a
+			  subdirectory or submenu.
+	<Up>		- select previous match (like CTRL-P)
+	CTRL-E		- end completion, go back to what was there before
+			  selecting a match.
+	CTRL-N		- go to the next entry
+	CTRL-P		- go to the previous entry
+	CTRL-Y		- accept the currently selected match and stop
+			  completion.
+
+	This makes the menus accessible from the console |console-menus|.
+
+	If you prefer the <Left> and <Right> keys to move the cursor instead
+	of selecting a different match, use this: >
+		:cnoremap <Left> <Space><BS><Left>
+		:cnoremap <Right> <Space><BS><Right>
+<
+	The "WildMenu" highlighting is used for displaying the current match
+	|hl-WildMenu|.
+
+						*'wildmode'* *'wim'*
+'wildmode' 'wim'	string	(Vim default: "full")
+			global
+	Completion mode that is used for the character specified with
+	'wildchar'.  It is a comma-separated list of up to four parts.  Each
+	part specifies what to do for each consecutive use of 'wildchar'.  The
+	first part specifies the behavior for the first use of 'wildchar',
+	The second part for the second use, etc.
+
+	Each part consists of a colon separated list consisting of the
+	following possible values:
+	""		Complete only the first match.
+	"full"		Complete the next full match.  After the last match,
+			the original string is used and then the first match
+			again.  Will also start 'wildmenu' if it is enabled.
+	"longest"	Complete till longest common string.  If this doesn't
+			result in a longer string, use the next part.
+	"list"		When more than one match, list all matches.
+	"lastused"	When completing buffer names and more than one buffer
+			matches, sort buffers by time last used (other than
+			the current buffer).
+	When there is only a single match, it is fully completed in all cases.
+
+	Examples of useful colon-separated values:
+	"longest:full"	Like "longest", but also start 'wildmenu' if it is
+			enabled.  Will not complete to the next full match.
+	"list:full"	When more than one match, list all matches and
+			complete first match.
+	"list:longest"	When more than one match, list all matches and
+			complete till longest common string.
+	"list:lastused" When more than one buffer matches, list all matches
+			and sort buffers by time last used (other than the
+			current buffer).
+
+	Examples: >
+		:set wildmode=full
+<	Complete first full match, next match, etc.  (the default) >
+		:set wildmode=longest,full
+<	Complete longest common string, then each full match >
+		:set wildmode=list:full
+<	List all matches and complete each full match >
+		:set wildmode=list,full
+<	List all matches without completing, then each full match >
+		:set wildmode=longest,list
+<	Complete longest common string, then list alternatives.
+	More info here: |cmdline-completion|.
+
+						*'wildoptions'* *'wop'*
+'wildoptions' 'wop'	string	(default "")
+			global
+	A list of words that change how |cmdline-completion| is done.
+	The following values are supported:
+	  fuzzy		Use |fuzzy-matching| to find completion matches. When
+			this value is specified, wildcard expansion will not
+			be used for completion.  The matches will be sorted by
+			the "best match" rather than alphabetically sorted.
+			This will find more matches than the wildcard
+			expansion. Currently fuzzy matching based completion
+			is not supported for file and directory names and
+			instead wildcard expansion is used.
+	  pum		Display the completion matches using the popup menu
+			in the same style as the |ins-completion-menu|.
+	  tagfile	When using CTRL-D to list matching tags, the kind of
+			tag and the file of the tag is listed.	Only one match
+			is displayed per line.  Often used tag kinds are:
+				d	#define
+				f	function
+
+						*'winaltkeys'* *'wak'*
+'winaltkeys' 'wak'	string	(default "menu")
+			global
+			{only used in Win32, Motif, GTK and Photon GUI}
+	Some GUI versions allow the access to menu entries by using the ALT
+	key in combination with a character that appears underlined in the
+	menu.  This conflicts with the use of the ALT key for mappings and
+	entering special characters.  This option tells what to do:
+	  no	Don't use ALT keys for menus.  ALT key combinations can be
+		mapped, but there is no automatic handling.  This can then be
+		done with the |:simalt| command.
+	  yes	ALT key handling is done by the windowing system.  ALT key
+		combinations cannot be mapped.
+	  menu	Using ALT in combination with a character that is a menu
+		shortcut key, will be handled by the windowing system.  Other
+		keys can be mapped.
+	If the menu is disabled by excluding 'm' from 'guioptions', the ALT
+	key is never used for the menu.
+	This option is not used for <F10>; on Win32 and with GTK <F10> will
+	select the menu, unless it has been mapped.
+
+						*'wincolor'* *'wcr'*
+'wincolor' 'wcr' string (default empty)
+			local to window
+	Highlight group name to use for this window instead of the Normal
+	color |hl-Normal|.
+
+						*'window'* *'wi'*
+'window' 'wi'		number  (default screen height - 1)
+			global
+	Window height used for |CTRL-F| and |CTRL-B| when there is only one
+	window and the value is smaller than 'lines' minus one.  The screen
+	will scroll 'window' minus two lines, with a minimum of one.
+	When 'window' is equal to 'lines' minus one CTRL-F and CTRL-B scroll
+	in a much smarter way, taking care of wrapping lines.
+	When resizing the Vim window, the value is smaller than 1 or more than
+	or equal to 'lines' it will be set to 'lines' minus 1.
+	Note: Do not confuse this with the height of the Vim window, use
+	'lines' for that.
+
+						*'winheight'* *'wh'* *E591*
+'winheight' 'wh'	number	(default 1)
+			global
+	Minimal number of lines for the current window.  This is not a hard
+	minimum, Vim will use fewer lines if there is not enough room.  If the
+	focus goes to a window that is smaller, its size is increased, at the
+	cost of the height of other windows.
+	Set 'winheight' to a small number for normal editing.
+	Set it to 999 to make the current window fill most of the screen.
+	Other windows will be only 'winminheight' high.  This has the drawback
+	that ":all" will create only two windows.  To avoid "vim -o 1 2 3 4"
+	to create only two windows, set the option after startup is done,
+	using the |VimEnter| event: >
+		au VimEnter * set winheight=999
+<	Minimum value is 1.
+	The height is not adjusted after one of the commands that change the
+	height of the current window.
+	'winheight' applies to the current window.  Use 'winminheight' to set
+	the minimal height for other windows.
+
+			*'winfixheight'* *'wfh'* *'nowinfixheight'* *'nowfh'*
+'winfixheight' 'wfh'	boolean	(default off)
+			local to window
+	Keep the window height when windows are opened or closed and
+	'equalalways' is set.  Also for |CTRL-W_=|.  Set by default for the
+	|preview-window| and |quickfix-window|.
+	The height may be changed anyway when running out of room.
+
+			*'winfixwidth'* *'wfw'* *'nowinfixwidth'* *'nowfw'*
+'winfixwidth' 'wfw'	boolean	(default off)
+			local to window
+	Keep the window width when windows are opened or closed and
+	'equalalways' is set.  Also for |CTRL-W_=|.
+	The width may be changed anyway when running out of room.
+
+						*'winminheight'* *'wmh'*
+'winminheight' 'wmh'	number	(default 1)
+			global
+	The minimal height of a window, when it's not the current window.
+	This is a hard minimum, windows will never become smaller.
+	When set to zero, windows may be "squashed" to zero lines (i.e. just a
+	status bar) if necessary.  They will return to at least one line when
+	they become active (since the cursor has to have somewhere to go.)
+	Use 'winheight' to set the minimal height of the current window.
+	This option is only checked when making a window smaller.  Don't use a
+	large number, it will cause errors when opening more than a few
+	windows.  A value of 0 to 3 is reasonable.
+
+						*'winminwidth'* *'wmw'*
+'winminwidth' 'wmw'	number	(default 1)
+			global
+	The minimal width of a window, when it's not the current window.
+	This is a hard minimum, windows will never become smaller.
+	When set to zero, windows may be "squashed" to zero columns (i.e. just
+	a vertical separator) if necessary.  They will return to at least one
+	line when they become active (since the cursor has to have somewhere
+	to go.)
+	Use 'winwidth' to set the minimal width of the current window.
+	This option is only checked when making a window smaller.  Don't use a
+	large number, it will cause errors when opening more than a few
+	windows.  A value of 0 to 12 is reasonable.
+
+						*'winptydll'*
+'winptydll'		string	(default "winpty32.dll" or "winpty64.dll")
+			global
+			{only available when compiled with the |terminal|
+			feature on MS-Windows}
+	Specifies the name of the winpty shared library, used for the
+	|:terminal| command. The default depends on whether Vim was built as a
+	32-bit or 64-bit executable.  If not found, "winpty.dll" is tried as
+	a fallback.
+	Environment variables are expanded |:set_env|.
+	This option cannot be set from a |modeline| or in the |sandbox|, for
+	security reasons.
+
+						*'winwidth'* *'wiw'* *E592*
+'winwidth' 'wiw'	number	(default 20)
+			global
+	Minimal number of columns for the current window.  This is not a hard
+	minimum, Vim will use fewer columns if there is not enough room.  If
+	the current window is smaller, its size is increased, at the cost of
+	the width of other windows.  Set it to 999 to make the current window
+	always fill the screen.  Set it to a small number for normal editing.
+	The width is not adjusted after one of the commands to change the
+	width of the current window.
+	'winwidth' applies to the current window.  Use 'winminwidth' to set
+	the minimal width for other windows.
+
+						*'wrap'* *'nowrap'*
+'wrap'			boolean	(default on)
+			local to window
+	This option changes how text is displayed.  It doesn't change the text
+	in the buffer, see 'textwidth' for that.
+	When on, lines longer than the width of the window will wrap and
+	displaying continues on the next line.  When off lines will not wrap
+	and only part of long lines will be displayed.  When the cursor is
+	moved to a part that is not shown, the screen will scroll
+	horizontally.
+	The line will be broken in the middle of a word if necessary.  See
+	'linebreak' to get the break at a word boundary.
+	To make scrolling horizontally a bit more useful, try this: >
+		:set sidescroll=5
+		:set listchars+=precedes:<,extends:>
+<	See 'sidescroll', 'listchars' and |wrap-off|.
+	This option can't be set from a |modeline| when the 'diff' option is
+	on.
+
+						*'wrapmargin'* *'wm'*
+'wrapmargin' 'wm'	number	(default 0)
+			local to buffer
+	Number of characters from the right window border where wrapping
+	starts.  When typing text beyond this limit, an <EOL> will be inserted
+	and inserting continues on the next line.
+	Options that add a margin, such as 'number' and 'foldcolumn', cause
+	the text width to be further reduced.  This is Vi compatible.
+	When 'textwidth' is non-zero, this option is not used.
+	This option is set to 0 when 'paste' is set and restored when 'paste'
+	is reset.
+	See also 'formatoptions' and |ins-textwidth|.
+
+				   *'wrapscan'* *'ws'* *'nowrapscan'* *'nows'*
+'wrapscan' 'ws'		boolean	(default on)			*E384* *E385*
+			global
+	Searches wrap around the end of the file.  Also applies to |]s| and
+	|[s|, searching for spelling mistakes.
+
+						   *'write'* *'nowrite'*
+'write'			boolean	(default on)
+			global
+	Allows writing files.  When not set, writing a file is not allowed.
+	Can be used for a view-only mode, where modifications to the text are
+	still allowed.  Can be reset with the |-m| or |-M| command line
+	argument.  Filtering text is still possible, even though this requires
+	writing a temporary file.
+
+				   *'writeany'* *'wa'* *'nowriteany'* *'nowa'*
+'writeany' 'wa'		boolean	(default off)
+			global
+	Allows writing to any file with no need for "!" override.
+
+			     *'writebackup'* *'wb'* *'nowritebackup'* *'nowb'*
+'writebackup' 'wb'	boolean	(default on with |+writebackup| feature, off
+					otherwise)
+			global
+	Make a backup before overwriting a file.  The backup is removed after
+	the file was successfully written, unless the 'backup' option is
+	also on.
+	WARNING: Switching this option off means that when Vim fails to write
+	your buffer correctly and then, for whatever reason, Vim exits, you
+	lose both the original file and what you were writing.  Only reset
+	this option if your file system is almost full and it makes the write
+	fail (and make sure not to exit Vim until the write was successful).
+	See |backup-table| for another explanation.
+	When the 'backupskip' pattern matches, a backup is not made anyway.
+	Depending on 'backupcopy' the backup is a new file or the original
+	file renamed (and a new file is written).
+	NOTE: This option is set to the default value when 'compatible' is
+	set.
+
+						*'writedelay'* *'wd'*
+'writedelay' 'wd'	number	(default 0)
+			global
+	The number of milliseconds to wait for each character sent to the
+	screen.  When non-zero, characters are sent to the terminal one by
+	one.  For debugging purposes.
+
+					   *'xtermcodes'* *'noxtermcodes'*
+'xtermcodes'		boolean	(default on)
+			global
+	When detecting xterm patchlevel 141 or higher with the termresponse
+	mechanism and this option is set, Vim will request the actual terminal
+	key codes and number of colors from the terminal.  This takes care of
+	various configuration options of the terminal that cannot be obtained
+	from the termlib/terminfo entry, see |xterm-codes|.
+	A side effect may be that t_Co changes and Vim will redraw the
+	display.
