| 7 Terminal information *terminal-info* | |
| 8 | |
| 9 Vim uses information about the terminal you are using to fill the screen and | |
| 10 recognize what keys you hit. If this information is not correct, the screen | |
| 11 may be messed up or keys may not be recognized. The actions which have to be | |
| 12 performed on the screen are accomplished by outputting a string of | |
| 13 characters. Special keys produce a string of characters. These strings are | |
| 14 stored in the terminal options, see |terminal-options|. | |
| 15 | |
| 16 NOTE: Most of this is not used when running the |GUI|. | |

| 24 ============================================================================== | |
| 25 1. Startup *startup-terminal* | |
| 26 | |
| 27 When Vim is started a default terminal type is assumed. For the Amiga this is | |
| 18972 | 28 a standard CLI window, for MS-Windows the pc terminal, for Unix an ansi |
| 29 terminal. A few other terminal types are always available, see below | |
| 30 |builtin-terms|. | |
| 7 | 31 |
| 32 You can give the terminal name with the '-T' Vim argument. If it is not given | |
| 33 Vim will try to get the name from the TERM environment variable. | |
| 34 | |
| 35 *termcap* *terminfo* *E557* *E558* *E559* | |
| 36 On Unix the terminfo database or termcap file is used. This is referred to as | |
| 37 "termcap" in all the documentation. At compile time, when running configure, | |
| 38 the choice whether to use terminfo or termcap is done automatically. When | |
| 39 running Vim the output of ":version" will show |+terminfo| if terminfo is | |
| 40 used. Also see |xterm-screens|. | |
| 41 | |
| 42 On non-Unix systems a termcap is only available if Vim was compiled with | |
| 43 TERMCAP defined. | |

48 terminals in the error message you get for `:set term=xxx` (when not running |
| 29885 | 49 the GUI). Also see |++builtin_terms|. |
| 7 | 50 |
| 51 If the termcap code is included Vim will try to get the strings for the | |
| 52 terminal you are using from the termcap file and the builtin termcaps. Both | |
| 53 are always used, if an entry for the terminal you are using is present. Which | |
| 54 one is used first depends on the 'ttybuiltin' option: | |
| 55 | |
| 56 'ttybuiltin' on 1: builtin termcap 2: external termcap | |
| 57 'ttybuiltin' off 1: external termcap 2: builtin termcap | |
| 58 | |
| 59 If an option is missing in one of them, it will be obtained from the other | |
| 60 one. If an option is present in both, the one first encountered is used. | |
| 61 | |
| 62 Which external termcap file is used varies from system to system and may | |
| 63 depend on the environment variables "TERMCAP" and "TERMPATH". See "man | |
| 64 tgetent". | |
| 65 | |
| 66 Settings depending on terminal *term-dependent-settings* | |
| 67 | |
| 68 If you want to set options or mappings, depending on the terminal name, you | |
| 69 can do this best in your .vimrc. Example: > | |
| 70 | |
| 71 if &term == "xterm" | |
| 72 ... xterm maps and settings ... | |
| 73 elseif &term =~ "vt10." | |
| 74 ... vt100, vt102 maps and settings ... | |
| 75 endif | |

| 14123 | 115 If your terminal supports bracketed paste, but the options are not set |
| 116 automatically, you can try using something like this: > | |
| 117 | |
| 118 if &term =~ "screen" | |
| 119 let &t_BE = "\e[?2004h" | |
| 120 let &t_BD = "\e[?2004l" | |

| 122 exec "set t_PE=\e[201~" | |
| 123 endif | |

| 25700 | 125 *tmux-integration* |
| 126 If you experience issues when running Vim inside tmux, here are a few hints. | |
| 127 You can comment-out parts if something doesn't work (it may depend on the | |
| 128 terminal that tmux is running in): > | |
| 129 | |
| 130 if !has('gui_running') && &term =~ '^\%(screen\|tmux\)' | |

| 137 let &t_8b = "\<Esc>[48;2;%lu;%lu;%lum" | |
| 138 | |
| 139 " Enable bracketed paste mode, see :help xterm-bracketed-paste | |

| 141 let &t_BD = "\<Esc>[?2004l" | |

| 155 execute "silent! set <xLeft>=\<Esc>[@;*D" | |
| 156 endif | |
| 157 < | |
| 7 | 158 *cs7-problem* |
| 159 Note: If the terminal settings are changed after running Vim, you might have | |
| 160 an illegal combination of settings. This has been reported on Solaris 2.5 | |
| 161 with "stty cs8 parenb", which is restored as "stty cs7 parenb". Use | |
| 162 "stty cs8 -parenb -istrip" instead, this is restored correctly. | |
| 163 | |
| 164 Some termcap entries are wrong in the sense that after sending 't_ks' the | |
| 165 cursor keys send codes different from the codes defined in the termcap. To | |
| 166 avoid this you can set 't_ks' (and 't_ke') to empty strings. This must be | |
| 167 done during initialization (see |initialization|), otherwise it's too late. | |
| 168 | |
| 169 Some termcap entries assume that the highest bit is always reset. For | |
| 170 example: The cursor-up entry for the Amiga could be ":ku=\E[A:". But the | |
| 171 Amiga really sends "\233A". This works fine if the highest bit is reset, | |
| 172 e.g., when using an Amiga over a serial line. If the cursor keys don't work, | |
| 173 try the entry ":ku=\233A:". | |
| 174 | |
| 175 Some termcap entries have the entry ":ku=\E[A:". But the Amiga really sends | |
| 176 "\233A". On output "\E[" and "\233" are often equivalent, on input they | |
| 177 aren't. You will have to change the termcap entry, or change the key code with | |
| 178 the :set command to fix this. | |
| 179 | |
| 180 Many cursor key codes start with an <Esc>. Vim must find out if this is a | |
| 181 single hit of the <Esc> key or the start of a cursor key sequence. It waits | |
| 182 for a next character to arrive. If it does not arrive within one second a | |
| 183 single <Esc> is assumed. On very slow systems this may fail, causing cursor | |
| 184 keys not to work sometimes. If you discover this problem reset the 'timeout' | |
| 185 option. Vim will wait for the next character to arrive after an <Esc>. If | |
| 186 you want to enter a single <Esc> you must type it twice. Resetting the | |
| 187 'esckeys' option avoids this problem in Insert mode, but you lose the | |
| 188 possibility to use cursor and function keys in Insert mode. | |
| 189 | |
| 190 On the Amiga the recognition of window resizing is activated only when the | |
| 191 terminal name is "amiga" or "builtin_amiga". | |
| 192 | |
| 193 Some terminals have confusing codes for the cursor keys. The televideo 925 is | |
| 194 such a terminal. It sends a CTRL-H for cursor-left. This would make it | |
| 195 impossible to distinguish a backspace and cursor-left. To avoid this problem | |
| 196 CTRL-H is never recognized as cursor-left. | |
| 197 | |
| 198 *vt100-cursor-keys* *xterm-cursor-keys* | |
| 199 Other terminals (e.g., vt100 and xterm) have cursor keys that send <Esc>OA, | |
| 200 <Esc>OB, etc. Unfortunately these are valid commands in insert mode: Stop | |
| 201 insert, Open a new line above the new one, start inserting 'A', 'B', etc. | |
| 202 Instead of performing these commands Vim will erroneously recognize this typed | |
| 203 key sequence as a cursor key movement. To avoid this and make Vim do what you | |
| 204 want in either case you could use these settings: > | |
| 205 :set notimeout " don't timeout on mappings | |
| 206 :set ttimeout " do timeout on terminal key codes | |
| 207 :set timeoutlen=100 " timeout after 100 msec | |
| 1621 | 208 This requires the key-codes to be sent within 100 msec in order to recognize |
| 7 | 209 them as a cursor key. When you type you normally are not that fast, so they |
| 210 are recognized as individual typed commands, even though Vim receives the same | |
| 211 sequence of bytes. | |
| 212 | |
| 213 *vt100-function-keys* *xterm-function-keys* | |
| 214 An xterm can send function keys F1 to F4 in two modes: vt100 compatible or | |
| 179 | 215 not. Because Vim may not know what the xterm is sending, both types of keys |
| 7 | 216 are recognized. The same happens for the <Home> and <End> keys. |
| 217 normal vt100 ~ | |
| 218 <F1> t_k1 <Esc>[11~ <xF1> <Esc>OP *<xF1>-xterm* | |
| 219 <F2> t_k2 <Esc>[12~ <xF2> <Esc>OQ *<xF2>-xterm* | |
| 220 <F3> t_k3 <Esc>[13~ <xF3> <Esc>OR *<xF3>-xterm* | |
| 221 <F4> t_k4 <Esc>[14~ <xF4> <Esc>OS *<xF4>-xterm* | |
| 222 <Home> t_kh <Esc>[7~ <xHome> <Esc>OH *<xHome>-xterm* | |
| 223 <End> t_@7 <Esc>[4~ <xEnd> <Esc>OF *<xEnd>-xterm* | |
| 224 | |
| 225 When Vim starts, <xF1> is mapped to <F1>, <xF2> to <F2> etc. This means that | |
| 226 by default both codes do the same thing. If you make a mapping for <xF2>, | |
| 227 because your terminal does have two keys, the default mapping is overwritten, | |
| 228 thus you can use the <F2> and <xF2> keys for something different. | |
| 229 | |
| 230 *xterm-shifted-keys* | |
| 231 Newer versions of xterm support shifted function keys and special keys. Vim | |
| 232 recognizes most of them. Use ":set termcap" to check which are supported and | |
| 233 what the codes are. Mostly these are not in a termcap, they are only | |
| 234 supported by the builtin_xterm termcap. | |
| 235 | |
| 179 | 236 *xterm-modifier-keys* |
| 237 Newer versions of xterm support Alt and Ctrl for most function keys. To avoid | |
| 238 having to add all combinations of Alt, Ctrl and Shift for every key a special | |
| 239 sequence is recognized at the end of a termcap entry: ";*X". The "X" can be | |
| 240 any character, often '~' is used. The ";*" stands for an optional modifier | |
| 241 argument. ";2" is Shift, ";3" is Alt, ";5" is Ctrl and ";9" is Meta (when | |
| 242 it's different from Alt). They can be combined. Examples: > | |
| 243 :set <F8>=^[[19;*~ | |
| 244 :set <Home>=^[[1;*H | |
| 245 Another speciality about these codes is that they are not overwritten by | |
| 246 another code. That is to avoid that the codes obtained from xterm directly | |
| 247 |t_RV| overwrite them. | |

251 stands for either "1" if a modifier follows, or nothing. |
| 26438 | 252 *arrow_modifiers* |
| 253 Several terminal emulators (alacritty, gnome, konsole, etc.) send special | |
| 254 codes for keys with modifiers, but these do not have an entry in the | |
| 255 termcap/terminfo database. You can make them work by adding a few lines in | |
| 256 your vimrc. For example, to make the Control modifier work with arrow keys | |
| 257 for the gnome terminal: > | |
| 258 if &term =~ 'gnome' | |
| 259 execute "set <xUp>=\<Esc>[@;*A" | |
| 260 execute "set <xDown>=\<Esc>[@;*B" | |
| 261 execute "set <xRight>=\<Esc>[@;*C" | |
| 262 execute "set <xLeft>=\<Esc>[@;*D" | |
| 263 endif | |
| 264 < *xterm-scroll-region* | |
| 7 | 265 The default termcap entry for xterm on Sun and other platforms does not |
| 266 contain the entry for scroll regions. Add ":cs=\E[%i%d;%dr:" to the xterm | |
| 267 entry in /etc/termcap and everything should work. | |
| 268 | |
| 269 *xterm-end-home-keys* | |
| 270 On some systems (at least on FreeBSD with XFree86 3.1.2) the codes that the | |
| 271 <End> and <Home> keys send contain a <Nul> character. To make these keys send | |
| 272 the proper key code, add these lines to your ~/.Xdefaults file: | |
| 273 | |
| 274 *VT100.Translations: #override \n\ | |
| 275 <Key>Home: string("0x1b") string("[7~") \n\ | |
| 276 <Key>End: string("0x1b") string("[8~") | |
| 277 | |
| 278 *xterm-8bit* *xterm-8-bit* | |
| 279 Xterm can be run in a mode where it uses 8-bit escape sequences. The CSI code | |
| 280 is used instead of <Esc>[. The advantage is that an <Esc> can quickly be | |
| 281 recognized in Insert mode, because it can't be confused with the start of a | |
| 282 special key. | |
| 283 For the builtin termcap entries, Vim checks if the 'term' option contains | |
| 284 "8bit" anywhere. It then uses 8-bit characters for the termcap entries, the | |
| 285 mouse and a few other things. You would normally set $TERM in your shell to | |
| 286 "xterm-8bit" and Vim picks this up and adjusts to the 8-bit setting | |
| 287 automatically. | |
| 288 When Vim receives a response to the |t_RV| (request version) sequence and it | |
| 289 starts with CSI, it assumes that the terminal is in 8-bit mode and will | |
| 290 convert all key sequences to their 8-bit variants. | |
| 291 | |
| 292 ============================================================================== | |
| 667 | 293 2. Terminal options *terminal-options* *termcap-options* *E436* |
| 7 | 294 |
| 295 The terminal options can be set just like normal options. But they are not | |
| 296 shown with the ":set all" command. Instead use ":set termcap". | |
| 297 | |
| 298 It is always possible to change individual strings by setting the | |
| 299 appropriate option. For example: > | |
| 300 :set t_ce=^V^[[K (CTRL-V, <Esc>, [, K) | |
| 301 | |
| 302 The options are listed below. The associated termcap code is always equal to | |
| 303 the last two characters of the option name. Only one termcap code is | |
| 304 required: Cursor motion, 't_cm'. | |
| 305 | |
| 6602 | 306 The options 't_da', 't_db', 't_ms', 't_xs', 't_xn' represent flags in the |
| 307 termcap. When the termcap flag is present, the option will be set to "y". | |
| 308 But any non-empty string means that the flag is set. An empty string means | |
| 309 that the flag is not set. 't_CS' works like this too, but it isn't a termcap | |
| 310 flag. | |

| 538 Note about t_so and t_mr: When the termcap entry "so" is not present the | |
| 539 entry for "mr" is used. And vice versa. The same is done for "se" and "me". | |
| 540 If your terminal supports both inversion and standout mode, you can see two | |
| 541 different modes. If your terminal supports only one of the modes, both will | |
| 542 look the same. | |
| 543 | |
| 33 | 544 *keypad-comma* |
| 7 | 545 The keypad keys, when they are not mapped, behave like the equivalent normal |
| 33 | 546 key. There is one exception: if you have a comma on the keypad instead of a |
| 547 decimal point, Vim will use a dot anyway. Use these mappings to fix that: > | |
| 548 :noremap <kPoint> , | |
| 549 :noremap! <kPoint> , | |
| 550 < *xterm-codes* | |
| 7 | 551 There is a special trick to obtain the key codes which currently only works |
| 552 for xterm. When |t_RV| is defined and a response is received which indicates | |
| 553 an xterm with patchlevel 141 or higher, Vim uses special escape sequences to | |
| 554 request the key codes directly from the xterm. The responses are used to | |
| 555 adjust the various t_ codes. This avoids the problem that the xterm can | |
| 556 produce different codes, depending on the mode it is in (8-bit, VT102, | |
| 557 VT220, etc.). The result is that codes like <xF1> are no longer needed. | |

| 29403 | 631 't_SI' is sent. When leaving Insert mode or Replace mode 't_EI' is used. |
| 632 Note: When 't_EI' is not set then 't_SI' and 't_SR' will not be sent. And | |
| 633 when 't_SI' or 't_SR' is not set then 't_EI' is sent only once. | |
| 634 | |
| 635 This can be used to change the shape or color of the cursor in Insert or | |
| 636 Replace mode. These are not standard termcap/terminfo entries, you need to set | |
| 637 them yourself. | |
| 36 | 638 Example for an xterm, this changes the color of the cursor: > |
| 639 if &term =~ "xterm" | |
| 640 let &t_SI = "\<Esc>]12;purple\x7" | |
| 6727 | 641 let &t_SR = "\<Esc>]12;red\x7" |
| 36 | 642 let &t_EI = "\<Esc>]12;blue\x7" |
| 643 endif | |
| 644 NOTE: When Vim exits the shape for Normal mode will remain. The shape from | |
| 645 before Vim started will not be restored. | |

658 {not available when compiled without the |+cursorshape| feature} |
| 36 | 659 |
| 7 | 660 *termcap-title* |
| 661 The 't_ts' and 't_fs' options are used to set the window title if the terminal | |
| 662 allows title setting via sending strings. They are sent before and after the | |
| 663 title string, respectively. Similar 't_IS' and 't_IE' are used to set the | |
| 664 icon text. These are Vim-internal extensions of the Unix termcap, so they | |
| 665 cannot be obtained from an external termcap. However, the builtin termcap | |
| 666 contains suitable entries for xterm and iris-ansi, so you don't need to set | |
| 667 them here. | |
| 668 *hpterm* | |
| 669 If inversion or other highlighting does not work correctly, try setting the | |
| 670 't_xs' option to a non-empty string. This makes the 't_ce' code be used to | |
| 671 remove highlighting from a line. This is required for "hpterm". Setting the | |
| 672 'weirdinvert' option has the same effect as making 't_xs' non-empty, and vice | |
| 673 versa. | |
| 674 | |
| 675 *scroll-region* | |
| 19116 | 676 Some termcaps do not include an entry for "cs" (scroll region), although the |
| 7 | 677 terminal does support it. For example: xterm on a Sun. You can use the |
| 678 builtin_xterm or define t_cs yourself. For example: > | |
| 679 :set t_cs=^V^[[%i%d;%dr | |
| 680 Where ^V is CTRL-V and ^[ is <Esc>. | |
| 681 | |
| 682 The vertical scroll region t_CV is not a standard termcap code. Vim uses it | |
| 683 internally in the GUI. But it can also be defined for a terminal, if you can | |
| 684 find one that supports it. The two arguments are the left and right column of | |
| 685 the region which to restrict the scrolling to. Just like t_cs defines the top | |
| 686 and bottom lines. Defining t_CV will make scrolling in vertically split | |
| 687 windows a lot faster. Don't set t_CV when t_da or t_db is set (text isn't | |
| 688 cleared when scrolling). | |
| 689 | |
| 690 Unfortunately it is not possible to deduce from the termcap how cursor | |
| 691 positioning should be done when using a scrolling region: Relative to the | |
| 692 beginning of the screen or relative to the beginning of the scrolling region. | |
| 19116 | 693 Most terminals use the first method. The 't_CS' option should be set to any |
| 694 string when cursor positioning is relative to the start of the scrolling | |
| 695 region. It should be set to an empty string otherwise. | |
| 7 | 696 |
| 697 Note for xterm users: The shifted cursor keys normally don't work. You can | |
| 698 make them work with the xmodmap command and some mappings in Vim. | |
| 699 | |
| 700 Give these commands in the xterm: | |
| 701 xmodmap -e "keysym Up = Up F13" | |
| 702 xmodmap -e "keysym Down = Down F16" | |
| 703 xmodmap -e "keysym Left = Left F18" | |
| 704 xmodmap -e "keysym Right = Right F19" | |
| 705 | |
| 706 And use these mappings in Vim: | |
| 707 :map <t_F3> <S-Up> | |
| 708 :map! <t_F3> <S-Up> | |
| 709 :map <t_F6> <S-Down> | |
| 710 :map! <t_F6> <S-Down> | |
| 711 :map <t_F8> <S-Left> | |
| 712 :map! <t_F8> <S-Left> | |
| 713 :map <t_F9> <S-Right> | |
| 714 :map! <t_F9> <S-Right> | |
| 715 | |
| 716 Instead of, say, <S-Up> you can use any other command that you want to use the | |
| 717 shift-cursor-up key for. (Note: To help people that have a Sun keyboard with | |
| 718 left side keys F14 is not used because it is confused with the undo key; F15 | |
| 719 is not used, because it does a window-to-front; F17 is not used, because it | |
| 720 closes the window. On other systems you can probably use them.) | |
| 721 | |
| 722 ============================================================================== | |
| 723 3. Window size *window-size* | |
| 724 | |
| 725 [This is about the size of the whole window Vim is using, not a window that is | |
| 726 created with the ":split" command.] | |
| 727 | |
| 728 If you are running Vim on an Amiga and the terminal name is "amiga" or | |
| 729 "builtin_amiga", the amiga-specific window resizing will be enabled. On Unix | |
| 730 systems three methods are tried to get the window size: | |
| 731 | |
| 732 - an ioctl call (TIOCGSIZE or TIOCGWINSZ, depends on your system) | |
| 733 - the environment variables "LINES" and "COLUMNS" | |
| 734 - from the termcap entries "li" and "co" | |
| 735 | |
| 736 If everything fails a default size of 24 lines and 80 columns is assumed. If | |
| 737 a window-resize signal is received the size will be set again. If the window | |
| 738 size is wrong you can use the 'lines' and 'columns' options to set the | |
| 739 correct values. | |
| 740 | |
| 741 One command can be used to set the screen size: | |

| 750 4. Slow and fast terminals *slow-fast-terminal* | |
| 751 *slow-terminal* | |
| 752 | |
| 753 If you have a fast terminal you may like to set the 'ruler' option. The | |
| 754 cursor position is shown in the status line. If you are using horizontal | |
| 755 scrolling ('wrap' option off) consider setting 'sidescroll' to a small | |
| 756 number. | |
| 757 | |
| 758 If you have a slow terminal you may want to reset the 'showcmd' option. | |
| 759 The command characters will not be shown in the status line. If the terminal | |
| 760 scrolls very slowly, set the 'scrolljump' to 5 or so. If the cursor is moved | |
| 761 off the screen (e.g., with "j") Vim will scroll 5 lines at a time. Another | |
| 762 possibility is to reduce the number of lines that Vim uses with the command | |
| 763 "z{height}<CR>". | |
| 764 | |
| 765 If the characters from the terminal are arriving with more than 1 second | |
| 766 between them you might want to set the 'timeout' and/or 'ttimeout' option. | |
| 767 See the "Options" chapter |options|. | |
| 768 | |
| 769 If your terminal does not support a scrolling region, but it does support | |
| 770 insert/delete line commands, scrolling with multiple windows may make the | |

773 verbose set ttyfast? |
| 7 | 774 |
| 775 If your terminal scrolls very slowly, but redrawing is not slow, set the | |
| 776 'ttyscroll' option to a small number, e.g., 3. This will make Vim redraw the | |
| 777 screen instead of scrolling, when there are more than 3 lines to be scrolled. | |
| 778 | |
| 779 If you are using a color terminal that is slow, use this command: > | |
| 780 hi NonText cterm=NONE ctermfg=NONE | |
| 781 This avoids that spaces are sent when they have different attributes. On most | |
| 782 terminals you can't see this anyway. | |
| 783 | |
| 784 If you are using Vim over a slow serial line, you might want to try running | |
| 785 Vim inside the "screen" program. Screen will optimize the terminal I/O quite | |
| 786 a bit. | |
| 787 | |
| 18972 | 788 If you are testing termcap options, but you cannot see what is happening, you |
| 789 might want to set the 'writedelay' option. When non-zero, one character is | |
| 790 sent to the terminal at a time. This makes the screen updating a lot slower, | |
| 791 making it possible to see what is happening. | |

| 797 to use the mouse in a GUI window is explained in |gui-mouse|. For scrolling | |

800 Don't forget to enable the mouse with this command: > |
| 7 | 801 :set mouse=a |
| 802 Otherwise Vim won't recognize the mouse in all modes (See 'mouse'). | |
| 803 | |
| 1621 | 804 Currently the mouse is supported for Unix in an xterm window, in a *BSD |
| 18972 | 805 console with |sysmouse|, in a Linux console (with GPM |gpm-mouse|), and |
| 806 in a Windows console. | |
| 7 | 807 Mouse clicks can be used to position the cursor, select an area and paste. |
| 808 | |
| 809 These characters in the 'mouse' option tell in which situations the mouse will | |
| 810 be used by Vim: | |
| 811 n Normal mode | |
| 812 v Visual mode | |
| 813 i Insert mode | |
| 814 c Command-line mode | |
| 815 h all previous modes when in a help file | |
| 816 a all previous modes | |
| 817 r for |hit-enter| prompt | |
| 818 | |
| 819 The default for 'mouse' is empty, the mouse is not used. Normally you would | |
| 820 do: > | |
| 821 :set mouse=a | |
| 822 to start using the mouse (this is equivalent to setting 'mouse' to "nvich"). | |
| 823 If you only want to use the mouse in a few modes or also want to use it for | |
| 824 the two questions you will have to concatenate the letters for those modes. | |
| 825 For example: > | |
| 826 :set mouse=nv | |
| 827 Will make the mouse work in Normal mode and Visual mode. > | |
| 828 :set mouse=h | |
| 829 Will make the mouse work in help files only (so you can use "g<LeftMouse>" to | |
| 830 jump to tags). | |
| 831 | |
| 832 Whether the selection that is started with the mouse is in Visual mode or | |
| 833 Select mode depends on whether "mouse" is included in the 'selectmode' | |
| 834 option. | |

849 exit the shell. 'mouse' can remain set to "a" then. |
| 7 | 850 *xterm-clipboard* |
| 28379 | 851 In the Motif GUI version, when running in a terminal and there is |
| 7 | 852 access to the X-server (DISPLAY is set), the copy and paste will behave like |
| 853 in the GUI. If not, the middle mouse button will insert the unnamed register. | |
| 854 In that case, here is how you copy and paste a piece of text: | |
| 855 | |
| 856 Copy/paste with the mouse and Visual mode ('mouse' option must be set, see | |
| 857 above): | |
| 858 1. Press left mouse button on first letter of text, move mouse pointer to last | |
| 859 letter of the text and release the button. This will start Visual mode and | |
| 860 highlight the selected area. | |
| 861 2. Press "y" to yank the Visual text in the unnamed register. | |
| 862 3. Click the left mouse button at the insert position. | |
| 863 4. Click the middle mouse button. | |
| 864 | |
| 865 Shortcut: If the insert position is on the screen at the same time as the | |
| 866 Visual text, you can do 2, 3 and 4 all in one: Click the middle mouse button | |
| 867 at the insert position. | |
| 868 | |
| 869 Note: When the |-X| command line argument is used, Vim will not connect to the | |
| 870 X server and copy/paste to the X clipboard (selection) will not work. Use the | |
| 871 shift key with the mouse buttons to let the xterm do the selection. | |
| 872 | |
| 873 *xterm-command-server* | |
| 874 When the X-server clipboard is available, the command server described in | |
| 875 |x11-clientserver| can be enabled with the --servername command line argument. | |
| 876 | |
| 877 *xterm-copy-paste* | |
| 878 NOTE: In some (older) xterms, it's not possible to move the cursor past column | |
| 5908 | 879 95 or 223. This is an xterm problem, not Vim's. Get a newer xterm |
| 880 |color-xterm|. Also see |'ttymouse'|. | |
| 7 | 881 |
| 882 Copy/paste in xterm with (current mode NOT included in 'mouse'): | |
| 883 1. Press left mouse button on first letter of text, move mouse pointer to last | |
| 884 letter of the text and release the button. | |
| 885 2. Use normal Vim commands to put the cursor at the insert position. | |
| 886 3. Press "a" to start Insert mode. | |
| 887 4. Click the middle mouse button. | |
| 888 5. Press ESC to end Insert mode. | |
| 889 (The same can be done with anything in 'mouse' if you keep the shift key | |
| 890 pressed while using the mouse.) | |
| 891 | |
| 892 Note: if you lose the 8th bit when pasting (special characters are translated | |
| 893 into other characters), you may have to do "stty cs8 -istrip -parenb" in your | |
| 894 shell before starting Vim. | |
| 895 | |
| 896 Thus in an xterm the shift and ctrl keys cannot be used with the mouse. Mouse | |
| 897 commands requiring the CTRL modifier can be simulated by typing the "g" key | |
| 898 before using the mouse: | |
| 899 "g<LeftMouse>" is "<C-LeftMouse> (jump to tag under mouse click) | |
| 900 "g<RightMouse>" is "<C-RightMouse> ("CTRL-T") | |
| 901 | |

| 941 When 'mousemodel' is "popup", these are different: | |
| 942 | |
| 943 Normal Mode: | |
| 944 event position selection change action ~ | |
| 945 cursor window ~ | |
| 946 <S-LeftMouse> yes start or extend (1) no | |

| 956 | |
| 957 (1) only if mouse pointer moved since press | |
| 958 (2) only if click is in same buffer | |
| 959 | |
| 960 Clicking the left mouse button causes the cursor to be positioned. If the | |
| 961 click is in another window that window is made the active window. When | |
| 962 editing the command-line the cursor can only be positioned on the | |
| 963 command-line. When in Insert mode Vim remains in Insert mode. If 'scrolloff' | |
| 964 is set, and the cursor is positioned within 'scrolloff' lines from the window | |
| 965 border, the text is scrolled. | |
| 966 | |
| 967 A selection can be started by pressing the left mouse button on the first | |
| 968 character, moving the mouse to the last character, then releasing the mouse | |
| 969 button. You will not always see the selection until you release the button, | |
| 18972 | 970 only in some versions (GUI, Win32) will the dragging be shown immediately. |
| 971 Note that you can make the text scroll by moving the mouse at least one | |
| 972 character in the first/last line in the window when 'scrolloff' is non-zero. | |
| 7 | 973 |
| 974 In Normal, Visual and Select mode clicking the right mouse button causes the | |
| 975 Visual area to be extended. When 'mousemodel' is "popup", the left button has | |
| 976 to be used while keeping the shift key pressed. When clicking in a window | |
| 977 which is editing another buffer, the Visual or Select mode is stopped. | |
| 978 | |
| 600 | 979 In Normal, Visual and Select mode clicking the right mouse button with the alt |
| 1121 | 980 key pressed causes the Visual area to become blockwise. When 'mousemodel' is |
| 600 | 981 "popup" the left button has to be used with the alt key. Note that this won't |
| 853 | 982 work on systems where the window manager consumes the mouse events when the |
| 983 alt key is pressed (it may move the window). | |
| 600 | 984 |
| 7 | 985 *double-click* |
| 18972 | 986 Double, triple and quadruple clicks are supported when the GUI is active, for |
| 987 Win32, and for an xterm (if the gettimeofday() function is available). For | |
| 988 selecting text, extra clicks extend the selection: | |
| 7 | 989 click select ~ |
| 990 double word or % match *<2-LeftMouse>* | |
| 991 triple line *<3-LeftMouse>* | |
| 992 quadruple rectangular block *<4-LeftMouse>* | |
| 993 Exception: In a Help window a double click jumps to help for the word that is | |
| 994 clicked on. | |
| 995 A double click on a word selects that word. 'iskeyword' is used to specify | |
| 996 which characters are included in a word. A double click on a character | |
| 997 that has a match selects until that match (like using "v%"). If the match is | |
| 998 an #if/#else/#endif block, the selection becomes linewise. | |
| 19116 | 999 For MS-Windows and xterm the time for double clicking can be set with the |
| 1000 'mousetime' option. For the other systems this time is defined outside of Vim. | |
| 7 | 1001 An example, for using a double click to jump to the tag under the cursor: > |
| 27903 | 1002 :map <2-LeftMouse> :exe "tag " .. expand("<cword>")<CR> |
| 7 | 1003 |
| 1004 Dragging the mouse with a double click (button-down, button-up, button-down | |
| 1005 and then drag) will result in whole words to be selected. This continues | |
| 1006 until the button is released, at which point the selection is per character | |
| 1007 again. | |
| 1008 | |
| 30967 | 1009 For scrolling with the mouse see |scroll-mouse-wheel|. |
| 1010 | |
| 7 | 1011 *gpm-mouse* |
| 1012 The GPM mouse is only supported when the |+mouse_gpm| feature was enabled at | |
| 1013 compile time. The GPM mouse driver (Linux console) does not support quadruple | |
| 1014 clicks. | |
| 1015 | |
| 1016 In Insert mode, when a selection is started, Vim goes into Normal mode | |
| 1017 temporarily. When Visual or Select mode ends, it returns to Insert mode. | |
| 1018 This is like using CTRL-O in Insert mode. Select mode is used when the | |
| 1019 'selectmode' option contains "mouse". | |
| 1621 | 1020 *sysmouse* |
| 1021 The sysmouse is only supported when the |+mouse_sysmouse| feature was enabled | |
| 1022 at compile time. The sysmouse driver (*BSD console) does not support keyboard | |
| 1023 modifiers. | |
| 7 | 1024 |
| 1025 *drag-status-line* | |
| 1026 When working with several windows, the size of the windows can be changed by | |
| 1027 dragging the status line with the mouse. Point the mouse at a status line, | |
| 1028 press the left button, move the mouse to the new position of the status line, | |
| 1029 release the button. Just clicking the mouse in a status line makes that window | |
| 1030 the current window, without moving the cursor. If by selecting a window it | |
| 1031 will change position or size, the dragging of the status line will look | |
| 1032 confusing, but it will work (just try it). | |
| 1033 | |
| 1034 *<MiddleRelease>* *<MiddleDrag>* | |
| 1035 Mouse clicks can be mapped. The codes for mouse clicks are: | |
| 1036 code mouse button normal action ~ | |
| 1037 <LeftMouse> left pressed set cursor position | |
| 1038 <LeftDrag> left moved while pressed extend selection | |
| 1039 <LeftRelease> left released set selection end | |
| 1040 <MiddleMouse> middle pressed paste text at cursor position | |
| 1041 <MiddleDrag> middle moved while pressed - | |
| 1042 <MiddleRelease> middle released - | |
| 1043 <RightMouse> right pressed extend selection | |
| 1044 <RightDrag> right moved while pressed extend selection | |
| 1045 <RightRelease> right released set selection end | |
| 1046 <X1Mouse> X1 button pressed - *X1Mouse* | |
| 1047 <X1Drag> X1 moved while pressed - *X1Drag* | |
| 1048 <X1Release> X1 button release - *X1Release* | |
| 1049 <X2Mouse> X2 button pressed - *X2Mouse* | |
| 1050 <X2Drag> X2 moved while pressed - *X2Drag* | |
| 1051 <X2Release> X2 button release - *X2Release* | |
| 1052 | |
| 1053 The X1 and X2 buttons refer to the extra buttons found on some mice. The | |
| 1054 'Microsoft Explorer' mouse has these buttons available to the right thumb. | |

1055 Currently X1 and X2 only work on Win32 and X11 environments. |
| 7 | 1056 |
| 1057 Examples: > | |
| 1058 :noremap <MiddleMouse> <LeftMouse><MiddleMouse> | |
| 1059 Paste at the position of the middle mouse button click (otherwise the paste | |
| 1060 would be done at the cursor position). > | |
| 1061 | |
| 1062 :noremap <LeftRelease> <LeftRelease>y | |
| 1063 Immediately yank the selection, when using Visual mode. | |
| 1064 | |
| 1065 Note the use of ":noremap" instead of "map" to avoid a recursive mapping. | |
| 1066 > | |
| 1067 :map <X1Mouse> <C-O> | |
| 1068 :map <X2Mouse> <C-I> | |
| 1069 Map the X1 and X2 buttons to go forwards and backwards in the jump list, see | |
| 1070 |CTRL-O| and |CTRL-I|. | |
| 1071 | |
| 1072 *mouse-swap-buttons* | |
| 1073 To swap the meaning of the left and right mouse buttons: > | |
