10 Most of this file is about Insert and Replace mode. At the end are a few
11 commands for inserting text in other ways.
12
13 An overview of the most often used commands can be found in chapter 24 of the
14 user manual |usr_24.txt|.
15
16 1. Special keys |ins-special-keys|
17 2. Special special keys |ins-special-special|
18 3. 'textwidth' and 'wrapmargin' options |ins-textwidth|
19 4. 'expandtab', 'smarttab' and 'softtabstop' options |ins-expandtab|
20 5. Replace mode |Replace-mode|
21 6. Virtual Replace mode |Virtual-Replace-mode|
22 7. Insert mode completion |ins-completion|
23 8. Insert mode commands |inserting|
24 9. Ex insert commands |inserting-ex|
25 10. Inserting a file |inserting-file|
26
27 Also see 'virtualedit', for moving the cursor to positions where there is no
28 character. Useful for editing a table.

30 ==============================================================================
31 1. Special keys *ins-special-keys*
32
33 In Insert and Replace mode, the following characters have a special meaning;
34 other characters are inserted directly. To insert one of these special
35 characters into the buffer, precede it with CTRL-V. To insert a <Nul>
36 character use "CTRL-V CTRL-@" or "CTRL-V 000". On some systems, you have to
37 use "CTRL-V 003" to insert a CTRL-C. Note: When CTRL-V is mapped you can
38 often use CTRL-Q instead |i_CTRL-Q|.
39
40 If you are working in a special language mode when inserting text, see the
41 'langmap' option, |'langmap'|, on how to avoid switching this mode on and off
42 all the time.
43
44 If you have 'insertmode' set, <Esc> and a few other keys get another meaning.
45 See |'insertmode'|.
46
47 char action ~
48 -----------------------------------------------------------------------
49 *i_CTRL-[* *i_<Esc>*
50 <Esc> or CTRL-[ End insert or Replace mode, go back to Normal mode. Finish
51 abbreviation.
52 Note: If your <Esc> key is hard to hit on your keyboard, train
53 yourself to use CTRL-[.
54 *i_CTRL-C*
55 CTRL-C Quit insert mode, go back to Normal mode. Do not check for
56 abbreviations.
57
58 *i_CTRL-@*
59 CTRL-@ Insert previously inserted text and stop insert. {Vi: only
60 when typed as first char, only up to 128 chars}
61 *i_CTRL-A*
62 CTRL-A Insert previously inserted text. {not in Vi}
63
64 *i_CTRL-H* *i_<BS>* *i_BS*
65 <BS> or CTRL-H Delete the character before the cursor (see |i_backspacing|
66 about joining lines).
67 See |:fixdel| if your <BS> key does not do what you want.
68 {Vi: does not delete autoindents}
69 *i_<Del>* *i_DEL*
70 <Del> Delete the character under the cursor. If the cursor is at
71 the end of the line, and the 'backspace' option includes
72 "eol", delete the <EOL>; the next line is appended after the
73 current one.
74 See |:fixdel| if your <Del> key does not do what you want.
75 {not in Vi}
76 *i_CTRL-W*
77 CTRL-W Delete the word before the cursor (see |i_backspacing| about
78 joining lines). See the section "word motions",
79 |word-motions|, for the definition of a word.
80 *i_CTRL-U*
81 CTRL-U Delete all entered characters in the current line (see
82 |i_backspacing| about joining lines).
83
84 *i_CTRL-I* *i_<Tab>* *i_Tab*
85 <Tab> or CTRL-I Insert a tab. If the 'expandtab' option is on, the
86 equivalent number of spaces is inserted (use CTRL-V <Tab> to
87 avoid the expansion; use CTRL-Q <Tab> if CTRL-V is mapped
88 |i_CTRL-Q|). See also the 'smarttab' option and
89 |ins-expandtab|.
90 *i_CTRL-J* *i_<NL>*
91 <NL> or CTRL-J Begin new line.
92 *i_CTRL-M* *i_<CR>*
93 <CR> or CTRL-M Begin new line.
94 *i_CTRL-K*
95 CTRL-K {char1} [char2]
96 Enter digraph (see |digraphs|). When {char1} is a special
97 key, the code for that key is inserted in <> form. For
98 example, the string "<S-Space>" can be entered by typing
99 <C-K><S-Space> (two keys). Neither char is considered for
100 mapping. {not in Vi}
101
102 CTRL-N Find next keyword (see |i_CTRL-N|). {not in Vi}
103 CTRL-P Find previous keyword (see |i_CTRL-P|). {not in Vi}
104
105 CTRL-R {0-9a-z"%#*+:.-=} *i_CTRL-R*
106 Insert the contents of a register. Between typing CTRL-R and
107 the second character, '"' will be displayed to indicate that
108 you are expected to enter the name of a register.
109 The text is inserted as if you typed it, but mappings and
110 abbreviations are not used. If you have options like
111 'textwidth', 'formatoptions', or 'autoindent' set, this will
112 influence what will be inserted. This is different from what
113 happens with the "p" command and pasting with the mouse.
114 Special registers:
115 '"' the unnamed register, containing the text of
116 the last delete or yank
117 '%' the current file name
118 '#' the alternate file name
119 '*' the clipboard contents (X11: primary selection)
120 '+' the clipboard contents
121 '/' the last search pattern
122 ':' the last command-line
123 '.' the last inserted text
124 '-' the last small (less than a line) delete
125 '=' the expression register: you are prompted to
126 enter an expression (see |expression|)
127 See |registers| about registers. {not in Vi}
128
129 CTRL-R CTRL-R {0-9a-z"%#*+/:.-=} *i_CTRL-R_CTRL-R*
130 Insert the contents of a register. Works like using a single
131 CTRL-R, but the text is inserted literally, not as if typed.
132 This differs when the register contains characters like <BS>.
133 Example, where register a contains "ab^Hc": >
134 CTRL-R a results in "ac".
135 CTRL-R CTRL-R a results in "ab^Hc".
136 < Options 'textwidth', 'formatoptions', etc. still apply. If
137 you also want to avoid these, use "<C-R><C-O>r", see below.
138 The '.' register (last inserted text) is still inserted as
139 typed. {not in Vi}
140
141 CTRL-R CTRL-O {0-9a-z"%#*+/:.-=} *i_CTRL-R_CTRL-O*
142 Insert the contents of a register literally and don't
143 auto-indent. Does the same as pasting with the mouse
144 |<MiddleMouse>|.
145 Does not replace characters!
146 The '.' register (last inserted text) is still inserted as
147 typed. {not in Vi}
148
149 CTRL-R CTRL-P {0-9a-z"%#*+/:.-=} *i_CTRL-R_CTRL-P*
150 Insert the contents of a register literally and fix the
151 indent, like |[<MiddleMouse>|.
152 Does not replace characters!
153 The '.' register (last inserted text) is still inserted as
154 typed. {not in Vi}
155
156 *i_CTRL-T*
157 CTRL-T Insert one shiftwidth of indent at the start of the current
158 line. The indent is always rounded to a 'shiftwidth' (this is
159 vi compatible). {Vi: only when in indent}
160 *i_CTRL-D*
161 CTRL-D Delete one shiftwidth of indent at the start of the current
162 line. The indent is always rounded to a 'shiftwidth' (this is
163 vi compatible). {Vi: CTRL-D works only when used after
164 autoindent}
165 *i_0_CTRL-D*
166 0 CTRL-D Delete all indent in the current line. {Vi: CTRL-D works
167 only when used after autoindent}
168 *i_^_CTRL-D*
169 ^ CTRL-D Delete all indent in the current line. The indent is
170 restored in the next line. This is useful when inserting a
171 label. {Vi: CTRL-D works only when used after autoindent}
172
173 *i_CTRL-V*
174 CTRL-V Insert next non-digit literally. For special keys, the
175 terminal code is inserted. It's also possible to enter the
176 decimal, octal or hexadecimal value of a character
177 |i_CTRL-V_digit|.
178 The characters typed right after CTRL-V are not considered for
179 mapping. {Vi: no decimal byte entry}
180 Note: When CTRL-V is mapped (e.g., to paste text) you can
181 often use CTRL-Q instead |i_CTRL-Q|.
182
183 *i_CTRL-Q*
184 CTRL-Q Same as CTRL-V.
185 Note: Some terminal connections may eat CTRL-Q, it doesn't
186 work then. It does work in the GUI.
187
188 CTRL-X Enter CTRL-X mode. This is a sub-mode where commands can
189 be given to complete words or scroll the window. See
190 |i_CTRL-X| and |ins-completion|. {not in Vi}
191
192 *i_CTRL-E*
193 CTRL-E Insert the character which is below the cursor. {not in Vi}
194 *i_CTRL-Y*
195 CTRL-Y Insert the character which is above the cursor. {not in Vi}
196 Note that for CTRL-E and CTRL-Y 'textwidth' is not used, to be
197 able to copy characters from a long line.
198
199 *i_CTRL-_*
200 CTRL-_ Switch between languages, as follows:
201 - When in a rightleft window, revins and nohkmap are toggled,
202 since English will likely be inserted in this case.
203 - When in a norightleft window, revins and hkmap are toggled,
204 since Hebrew will likely be inserted in this case.
205
206 CTRL-_ moves the cursor to the end of the typed text.
207
208 This command is only available when the 'allowrevins' option
209 is set.
210 Please refer to |rileft.txt| for more information about
211 right-to-left mode.
212 {not in Vi}
213 Only if compiled with the |+rightleft| feature (which is not
214 the default).
215 *i_CTRL-^*
216 CTRL-^ Toggle the use of typing language characters.
217 When language |:lmap| mappings are defined:
218 - If 'iminsert' is 1 (langmap mappings used) it becomes 0 (no
219 langmap mappings used).
220 - If 'iminsert' has another value it becomes 1, thus langmap
221 mappings are enabled.
222 When no language mappings are defined:
223 - If 'iminsert' is 2 (Input Method used) it becomes 0 (no
224 Input Method used).
225 - If 'iminsert' has another value it becomes 2, thus the Input
226 Method is enabled.
227 When set to 1, the value of the "b:keymap_name" variable, the
228 'keymap' option or "<lang>" appears in the status line.
229 The language mappings are normally used to type characters
230 that are different from what the keyboard produces. The
231 'keymap' option can be used to install a whole number of them.
232 {not in Vi}
233
234 *i_CTRL-]*
235 CTRL-] Trigger abbreviation, without inserting a character. {not in
236 Vi}
237
238 *i_<Insert>*
239 <Insert> Toggle between Insert and Replace mode. {not in Vi}
240 -----------------------------------------------------------------------
241
242 *i_backspacing*
243 The effect of the <BS>, CTRL-W, and CTRL-U depend on the 'backspace' option
244 (unless 'revins' is set). This is a comma separated list of items:
245
246 item action ~
247 indent allow backspacing over autoindent
248 eol allow backspacing over end-of-line (join lines)
249 start allow backspacing over the start position of insert; CTRL-W and
250 CTRL-U stop once at the start position
251
252 When 'backspace' is empty, Vi compatible backspacing is used. You cannot
253 backspace over autoindent, before column 1 or before where insert started.
254
255 For backwards compatibility the values "0", "1" and "2" are also allowed, see
256 |'backspace'|.
257
258 If the 'backspace' option does contain "eol" and the cursor is in column 1
259 when one of the three keys is used, the current line is joined with the
260 previous line. This effectively deletes the <EOL> in front of the cursor.
261 {Vi: does not cross lines, does not delete past start position of insert}
262
263 *i_CTRL-V_digit*
264 With CTRL-V the decimal, octal or hexadecimal value of a character can be
265 entered directly. This way you can enter any character, except a line break
266 (<NL>, value 10). There are five ways to enter the character value:
267
268 first char mode max nr of chars max value ~
269 (none) decimal 3 255
270 o or O octal 3 255
271 x or X hexadecimal 2 ff (255)
272 u hexadecimal 4 ffff (65535)
273 U hexadecimal 8 7fffffff (2147483647)
274
275 Normally you would type the maximum number of characters. Thus to enter a
276 space (value 32) you would type <C-V>032. You can omit the leading zero, in
277 which case the character typed after the number must be a non-digit. This
278 happens for the other modes as well: As soon as you type a character that is
279 invalid for the mode, the value before it will be used and the "invalid"
280 character is dealt with in the normal way.
281
282 If you enter a value of 10, it will end up in the file as a 0. The 10 is a
283 <NL>, which is used internally to represent the <Nul> character. When writing
284 the buffer to a file, the <NL> character is translated into <Nul>. The <NL>
285 character is written at the end of each line. Thus if you want to insert a
286 <NL> character in a file you will have to make a line break.
287
288 *i_CTRL-X* *insert_expand*
289 CTRL-X enters a sub-mode where several commands can be used. Most of these
290 commands do keyword completion; see |ins-completion|. These are not available
291 when Vim was compiled without the |+insert_expand| feature.
292
293 Two commands can be used to scroll the window up or down, without exiting
294 insert mode:
295
296 *i_CTRL-X_CTRL-E*
297 CTRL-X CTRL-E scroll window one line up.
298
299 *i_CTRL-X_CTRL-Y*
300 CTRL-X CTRL-Y scroll window one line down.
301
302 After CTRL-X is pressed, each CTRL-E (CTRL-Y) scrolls the window up (down) by
303 one line unless that would cause the cursor to move from its current position
304 in the file. As soon as another key is pressed, CTRL-X mode is exited and
305 that key is interpreted as in Insert mode.
306
307
308 ==============================================================================
309 2. Special special keys *ins-special-special*
310
311 The following keys are special. They stop the current insert, do something,
312 and then restart insertion. This means you can do something without getting
313 out of Insert mode. This is very handy if you prefer to use the Insert mode
314 all the time, just like editors that don't have a separate Normal mode. You
315 may also want to set the 'backspace' option to "indent,eol,start" and set the
316 'insertmode' option. You can use CTRL-O if you want to map a function key to
317 a command.
318
319 The changes (inserted or deleted characters) before and after these keys can
320 be undone separately. Only the last change can be redone and always behaves
321 like an "i" command.
322
323 char action ~
324 -----------------------------------------------------------------------
325 <Up> cursor one line up *i_<Up>*
326 <Down> cursor one line down *i_<Down>*
327 CTRL-G <Up> cursor one line up, insert start column *i_CTRL-G_<Up>*
328 CTRL-G k cursor one line up, insert start column *i_CTRL-G_k*
329 CTRL-G CTRL-K cursor one line up, insert start column *i_CTRL-G_CTRL-K*
330 CTRL-G <Down> cursor one line down, insert start column *i_CTRL-G_<Down>*
331 CTRL-G j cursor one line down, insert start column *i_CTRL-G_j*
332 CTRL-G CTRL-J cursor one line down, insert start column *i_CTRL-G_CTRL-J*
333 <Left> cursor one character left *i_<Left>*
334 <Right> cursor one character right *i_<Right>*
335 <S-Left> cursor one word back (like "b" command) *i_<S-Left>*
336 <C-Left> cursor one word back (like "b" command) *i_<C-Left>*
337 <S-Right> cursor one word forward (like "w" command) *i_<S-Right>*
338 <C-Right> cursor one word forward (like "w" command) *i_<C-Right>*
339 <Home> cursor to first char in the line *i_<Home>*
340 <End> cursor to after last char in the line *i_<End>*
341 <C-Home> cursor to first char in the file *i_<C-Home>*
342 <C-End> cursor to after last char in the file *i_<C-End>*
343 <LeftMouse> cursor to position of mouse click *i_<LeftMouse>*
344 <S-Up> move window one page up *i_<S-Up>*
345 <PageUp> move window one page up *i_<PageUp>*
346 <S-Down> move window one page down *i_<S-Down>*
347 <PageDown> move window one page down *i_<PageDown>*
348 <MouseDown> scroll three lines down *i_<MouseDown>*
349 <S-MouseDown> scroll a full page down *i_<S-MouseDown>*
350 <MouseUp> scroll three lines up *i_<MouseUp>*
351 <S-MouseUp> scroll a full page up *i_<S-MouseUp>*
352 CTRL-O execute one command, return to Insert mode *i_CTRL-O*
353 CTRL-G u break undo sequence, start new change *i_CTRL-G_u*
354 -----------------------------------------------------------------------
355
356 Note: If the cursor keys take you out of Insert mode, check the 'noesckeys'
357 option.
358
359 The CTRL-O command sometimes has a side effect: If the cursor was beyond the
360 end of the line, it will be put on the last character in the line. In
361 mappings it's often better to use <Esc> (first put an "x" in the text, <Esc>
362 will then always put the cursor on it).
363
364 The shifted cursor keys are not available on all terminals.
365
366 Another side effect is that a count specified before the "i" or "a" command is
367 ignored. That is because repeating the effect of the command after CTRL-O is
368 too complicated.
369
370 An example for using CTRL-G u: >
371
372 :inoremap <C-H> <C-G>u<C-H>
373
374 This redefines the backspace key to start a new undo sequence. You can now
375 undo the effect of the backspace key, without changing what you typed before
376 that, with CTRL-O u.
377
378 When the 'whichwrap' option is set appropriately, the <Left> and <Right>
379 keys on the first/last character in the line make the cursor wrap to the
380 previous/next line.
381
382 The CTRL-G j and CTRL-G k commands can be used to insert text in front of a
383 column. Example: >
384 int i;
385 int j;
386 Position the cursor on the first "int", type "istatic<C-G>j ". The
387 result is: >
388 static int i;
389 int j;
390 When inserting the same text in front of the column in every line, use the
391 Visual blockwise command "I" |v_b_I|.
392
393 ==============================================================================
394 3. 'textwidth' and 'wrapmargin' options *ins-textwidth*
395
396 The 'textwidth' option can be used to automatically break a line before it
397 gets too long. Set the 'textwidth' option to the desired maximum line
398 length. If you then type more characters (not spaces or tabs), the
399 last word will be put on a new line (unless it is the only word on the
400 line). If you set 'textwidth' to 0, this feature is disabled.
401
402 The 'wrapmargin' option does almost the same. The difference is that
403 'textwidth' has a fixed width while 'wrapmargin' depends on the width of the
404 screen. When using 'wrapmargin' this is equal to using 'textwidth' with a
405 value equal to (columns - 'wrapmargin'), where columns is the width of the
406 screen.
407
408 When 'textwidth' and 'wrapmargin' are both set, 'textwidth' is used.
409
410 If you don't really want to break the line, but view the line wrapped at a
411 convenient place, see the 'linebreak' option.
412
413 The line is only broken automatically when using insert mode, or when
414 appending to a line. When in replace mode and the line length is not
415 changed, the line will not be broken.
416
417 Long lines are broken if you enter a non-white character after the margin.
418 The situations where a line will be broken can be restricted by adding
419 characters to the 'formatoptions' option:
420 "l" Only break a line if it was not longer than 'textwidth' when the insert
421 started.
422 "v" Only break at a white character that has been entered during the
423 current insert command. This is mostly Vi-compatible.
424 "lv" Only break if the line was not longer than 'textwidth' when the insert
425 started and only at a white character that has been entered during the
426 current insert command. Only differs from "l" when entering non-white
427 characters while crossing the 'textwidth' boundary.
428
429 If you want to format a block of text, you can use the "gq" operator. Type
430 "gq" and a movement command to move the cursor to the end of the block. In
431 many cases, the command "gq}" will do what you want (format until the end of
432 paragraph). Alternatively, you can use "gqap", which will format the whole
433 paragraph, no matter where the cursor currently is. Or you can use Visual
434 mode: hit "v", move to the end of the block, and type "gq". See also |gq|.
435
436 ==============================================================================
437 4. 'expandtab', 'smarttab' and 'softtabstop' options *ins-expandtab*
438
439 If the 'expandtab' option is on, spaces will be used to fill the amount of
440 whitespace of the tab. If you want to enter a real <Tab>, type CTRL-V first
441 (use CTRL-Q when CTRL-V is mapped |i_CTRL-Q|).
442 The 'expandtab' option is off by default. Note that in Replace mode, a single
443 character is replaced with several spaces. The result of this is that the
444 number of characters in the line increases. Backspacing will delete one
445 space at a time. The original character will be put back for only one space
446 that you backspace over (the last one). {Vi does not have the 'expandtab'
447 option}
448
449 *ins-smarttab*
450 When the 'smarttab' option is on, a <Tab> inserts 'shiftwidth' positions at
451 the beginning of a line and 'tabstop' positions in other places. This means
452 that often spaces instead of a <Tab> character are inserted. When 'smarttab
453 is off, a <Tab> always inserts 'tabstop' positions, and 'shiftwidth' is only
454 used for ">>" and the like. {not in Vi}
455
456 *ins-softtabstop*
457 When the 'softtabstop' option is non-zero, a <Tab> inserts 'softtabstop'
458 positions, and a <BS> used to delete white space, will delete 'softtabstop'
459 positions. This feels like 'tabstop' was set to 'softtabstop', but a real
460 <Tab> character still takes 'tabstop' positions, so your file will still look
461 correct when used by other applications.
462
463 If 'softtabstop' is non-zero, a <BS> will try to delete as much white space to
464 move to the previous 'softtabstop' position, except when the previously
465 inserted character is a space, then it will only delete the character before
466 the cursor. Otherwise you cannot always delete a single character before the
467 cursor. You will have to delete 'softtabstop' characters first, and then type
468 extra spaces to get where you want to be.
469
470 ==============================================================================
471 5. Replace mode *Replace* *Replace-mode* *mode-replace*
472
473 Enter Replace mode with the "R" command in normal mode.
474
475 In Replace mode, one character in the line is deleted for every character you
476 type. If there is no character to delete (at the end of the line), the
477 typed character is appended (as in Insert mode). Thus the number of
478 characters in a line stays the same until you get to the end of the line.
479 If a <NL> is typed, a line break is inserted and no character is deleted.
480
481 Be careful with <Tab> characters. If you type a normal printing character in
482 its place, the number of characters is still the same, but the number of
483 columns will become smaller.
484
485 If you delete characters in Replace mode (with <BS>, CTRL-W, or CTRL-U), what
486 happens is that you delete the changes. The characters that were replaced
487 are restored. If you had typed past the existing text, the characters you
488 added are deleted. This is effectively a character-at-a-time undo.
489
490 If the 'expandtab' option is on, a <Tab> will replace one character with
491 several spaces. The result of this is that the number of characters in the
492 line increases. Backspacing will delete one space at a time. The original
493 character will be put back for only one space that you backspace over (the
494 last one). {Vi does not have the 'expandtab' option}
495
496 ==============================================================================
497 6. Virtual Replace mode *vreplace-mode* *Virtual-Replace-mode*
498
499 Enter Virtual Replace mode with the "gR" command in normal mode.
500 {not available when compiled without the +vreplace feature}
501 {Vi does not have Virtual Replace mode}
502
503 Virtual Replace mode is similar to Replace mode, but instead of replacing
504 actual characters in the file, you are replacing screen real estate, so that
505 characters further on in the file never appear to move.
506
507 So if you type a <Tab> it may replace several normal characters, and if you
508 type a letter on top of a <Tab> it may not replace anything at all, since the
509 <Tab> will still line up to the same place as before.
510
511 Typing a <NL> still doesn't cause characters later in the file to appear to
512 move. The rest of the current line will be replaced by the <NL> (that is,
513 they are deleted), and replacing continues on the next line. A new line is
514 NOT inserted unless you go past the end of the file.
515
516 Interesting effects are seen when using CTRL-T and CTRL-D. The characters
517 before the cursor are shifted sideways as normal, but characters later in the
518 line still remain still. CTRL-T will hide some of the old line under the
519 shifted characters, but CTRL-D will reveal them again.
520
521 As with Replace mode, using <BS> etc will bring back the characters that were
522 replaced. This still works in conjunction with 'smartindent', CTRL-T and
523 CTRL-D, 'expandtab', 'smarttab', 'softtabstop', etc.
524
525 In 'list' mode, Virtual Replace mode acts as if it was not in 'list' mode,
526 unless "L" is in 'cpoptions'.
527
528 Note that the only times characters beyond the cursor should appear to move
529 are in 'list' mode, and occasionally when 'wrap' is set (and the line changes
530 length to become shorter or wider than the width of the screen), or
531 momentarily when typing over a CTRL character. A CTRL character takes up two
532 screen spaces. When replacing it with two normal characters, the first will
533 be inserted and the second will replace the CTRL character.
534
535 This mode is very useful for editing <Tab> separated columns in tables, for
536 entering new data while keeping all the columns aligned.
537
538 ==============================================================================
539 7. Insert mode completion *ins-completion*
540
541 In Insert and Replace modes, there are several commands to complete part of a
542 keyword or line that has been typed. This is useful if you are using
543 complicated keywords (e.g., function names with capitals and underscores).
544
545 These commands are not available when the |+insert_expand| feature was
546 disabled at compile time.
547
548 Completion can be done for:
549
550 1. Whole lines |i_CTRL-X_CTRL-L|
551 2. keywords in the current file |i_CTRL-X_CTRL-N|
552 3. keywords in 'dictionary' |i_CTRL-X_CTRL-K|
553 4. keywords in 'thesaurus', thesaurus-style |i_CTRL-X_CTRL-T|
554 5. keywords in the current and included files |i_CTRL-X_CTRL-I|
555 6. tags |i_CTRL-X_CTRL-]|
556 7. file names |i_CTRL-X_CTRL-F|
557 8. definitions or macros |i_CTRL-X_CTRL-D|
558 9. Vim command-line |i_CTRL-X_CTRL-V|
559 10. keywords in 'complete' |i_CTRL-N|
560
561 All these (except 2) are done in CTRL-X mode. This is a sub-mode of Insert
562 and Replace modes. You enter CTRL-X mode by typing CTRL-X and one of the
563 CTRL-X commands. You exit CTRL-X mode by typing a key that is not a valid
564 CTRL-X mode command. Valid keys are the CTRL-X command itself, CTRL-N (next),
565 and CTRL-P (previous).
566
567 Also see the 'infercase' option if you want to adjust the case of the match.
568
569 Note: The keys that are valid in CTRL-X mode are not mapped. This allows for
570 ":map ^F ^X^F" to work (where ^F is CTRL-F and ^X is CTRL-X). The key that
571 ends CTRL-X mode (any key that is not a valid CTRL-X mode command) is mapped.
572 Also, when doing completion with 'complete' mappings apply as usual.
573
574 The following mappings are suggested to make typing the completion commands
575 a bit easier (although they will hide other commands): >
576 :inoremap ^] ^X^]
577 :inoremap ^F ^X^F
578 :inoremap ^D ^X^D
579 :inoremap ^L ^X^L
580
581 As a special case, typing CTRL-R to perform register insertion (see
582 |i_CTRL-R|) will not exit CTRL-X mode. This is primarily to allow the use of
583 the '=' register to call some function to determine the next operation. If
584 the contents of the register (or result of the '=' register evaluation) are
585 not valid CTRL-X mode keys, then CTRL-X mode will be exited as if those keys
586 had been typed.
587
588 For example, the following will map <Tab> to either actually insert a <Tab> if
589 the current line is currently only whitespace, or start/continue a CTRL-N
590 completion operation: >
591
592 function! CleverTab()
593 if strpart( getline('.'), 0, col('.')-1 ) =~ '^\s*$'
594 return "\<Tab>"
595 else
596 return "\<C-N>"
597 endfunction
598 inoremap <Tab> <C-R>=CleverTab()<CR>
599
600
601
602 Completing whole lines *compl-whole-line*
603
604 *i_CTRL-X_CTRL-L*
605 CTRL-X CTRL-L Search backwards for a line that starts with the
606 same characters as in the current line before the
607 cursor. Indent is ignored. The found line is
608 inserted in front of the cursor.
609 The 'complete' option is used to decide in which
610 buffers a match is searched for. But only loaded
611 buffers are used.
612 CTRL-L or
613 CTRL-P Search backwards for next matching line. This line
614 replaces the previous matching line.
615
616 CTRL-N Search forward for next matching line. This line
617 replaces the previous matching line.
618
619 CTRL-X CTRL-L After expanding a line you can additionally get the
620 line next to it by typing CTRL-X CTRL-L again, unless
621 a double CTRL-X is used.
622
623 Completing keywords in current file *compl-current*
624
625 *i_CTRL-X_CTRL-P*
626 *i_CTRL-X_CTRL-N*
627 CTRL-X CTRL-N Search forwards for words that start with the keyword
628 in front of the cursor. The found keyword is inserted
629 in front of the cursor.
630
631 CTRL-X CTRL-P Search backwards for words that start with the keyword
632 in front of the cursor. The found keyword is inserted
633 in front of the cursor.
634
635 CTRL-N Search forward for next matching keyword. This
636 keyword replaces the previous matching keyword.
637
638 CTRL-P Search backwards for next matching keyword. This
639 keyword replaces the previous matching keyword.
640
641 CTRL-X CTRL-N or
642 CTRL-X CTRL-P Further use of CTRL-X CTRL-N or CTRL-X CTRL-P will
643 copy the words following the previous expansion in
644 other contexts unless a double CTRL-X is used.
645
646 If there is a keyword in front of the cursor (a name made out of alphabetic
647 characters and characters in 'iskeyword'), it is used as the search pattern,
648 with "\<" prepended (meaning: start of a word). Otherwise "\<\k\k" is used
649 as search pattern (start of any keyword of at least two characters).
650
651 In Replace mode, the number of characters that are replaced depends on the
652 length of the matched string. This works like typing the characters of the
653 matched string in Replace mode.
654
655 If there is not a valid keyword character before the cursor, any keyword of
656 at least two characters is matched.
657 e.g., to get:
658 printf("(%g, %g, %g)", vector[0], vector[1], vector[2]);
659 just type:
660 printf("(%g, %g, %g)", vector[0], ^P[1], ^P[2]);
661
662 Multiple repeats of the same completion are skipped; thus a different match
663 will be inserted at each CTRL-N and CTRL-P (unless there is only one
664 matching keyword).
665
666 Single character matches are never included, as they usually just get in
667 the way of what you were really after.
668 e.g., to get:
669 printf("name = %s\n", name);
670 just type:
671 printf("name = %s\n", n^P);
672 or even:
673 printf("name = %s\n", ^P);
674 The 'n' in '\n' is skipped.
675
676 After expanding a word, you can use CTRL-X CTRL-P or CTRL-X CTRL-N to get the
677 word following the expansion in other contexts. These sequences search for
678 the text just expanded and further expand by getting an extra word. This is
679 useful if you need to repeat a sequence of complicated words. Although CTRL-P
680 and CTRL-N look just for strings of at least two characters, CTRL-X CTRL-P and
681 CTRL-X CTRL-N can be used to expand words of just one character.
682 e.g., to get:
683 M&eacute;xico
684 you can type:
685 M^N^P^X^P^X^P
686 CTRL-N starts the expansion and then CTRL-P takes back the single character
687 "M", the next two CTRL-X CTRL-P's get the words "&eacute" and ";xico".
688
689 If the previous expansion was split, because it got longer than 'textwidth',
690 then just the text in the current line will be used.
691
692 If the match found is at the end of a line, then the first word in the next
693 line will be inserted and the message "word from next line" displayed, if
694 this word is accepted the next CTRL-X CTRL-P or CTRL-X CTRL-N will search
695 for those lines starting with this word.
696
697
698 Completing keywords in 'dictionary' *compl-dictionary*
699
700 *i_CTRL-X_CTRL-K*
701 CTRL-X CTRL-K Search the files given with the 'dictionary' option
702 for words that start with the keyword in front of the
703 cursor. This is like CTRL-N, but only the dictionary
704 files are searched, not the current file. The found
705 keyword is inserted in front of the cursor. This
706 could potentially be pretty slow, since all matches
707 are found before the first match is used. By default,
708 the 'dictionary' option is empty.
709 For suggestions where to find a list of words, see the
710 'dictionary' option.
711
712 CTRL-K or
713 CTRL-N Search forward for next matching keyword. This
714 keyword replaces the previous matching keyword.
715
716 CTRL-P Search backwards for next matching keyword. This
717 keyword replaces the previous matching keyword.
718
719 *i_CTRL-X_CTRL-T*
720 CTRL-X CTRL-T Works as CTRL-X CTRL-K, but in a special way. It uses
721 the 'thesaurus' option instead of 'dictionary'. If a
722 match is found in the thesaurus file, all the
723 remaining words on the same line are included as
724 matches, even though they don't complete the word.
725 Thus a word can be completely replaced.
726
727 For an example, imagine the 'thesaurus' file has a
728 line like this: >
729 angry furious mad enraged
730 < Placing the cursor after the letters "ang" and typing
731 CTRL-X CTRL-T would complete the word "angry";
732 subsequent presses would change the word to "furious",
733 "mad" etc.
734 Other uses include translation between two languages,
735 or grouping API functions by keyword.
736
737 CTRL-T or
738 CTRL-N Search forward for next matching keyword. This
739 keyword replaces the previous matching keyword.
740
741 CTRL-P Search backwards for next matching keyword. This
742 keyword replaces the previous matching keyword.
743
744
745 Completing keywords in the current and included files *compl-keyword*
746
747 The 'include' option is used to specify a line that contains an include file
748 name. The 'path' option is used to search for include files.
749
750 *i_CTRL-X_CTRL-I*
751 CTRL-X CTRL-I Search for the first keyword in the current and
752 included files that starts with the same characters
753 as those before the cursor. The matched keyword is
754 inserted in front of the cursor.
755
756 CTRL-N Search forwards for next matching keyword. This
757 keyword replaces the previous matching keyword.
758 Note: CTRL-I is the same as <Tab>, which is likely to
759 be typed after a successful completion, therefore
760 CTRL-I is not used for searching for the next match.
761
762 CTRL-P Search backward for previous matching keyword. This
763 keyword replaces the previous matching keyword.
764
765 CTRL-X CTRL-I Further use of CTRL-X CTRL-I will copy the words
766 following the previous expansion in other contexts
767 unless a double CTRL-X is used.
768
769 Completing tags *compl-tag*
770 *i_CTRL-X_CTRL-]*
771 CTRL-X CTRL-] Search for the first tag that starts with the same
772 characters as before the cursor. The matching tag is
773 inserted in front of the cursor. Alphabetic
774 characters and characters in 'iskeyword' are used
775 to decide which characters are included in the tag
776 name (same as for a keyword). See also |CTRL-]|.
777 The 'showfulltag' option can be used to add context
778 from around the tag definition.
779 CTRL-] or
780 CTRL-N Search forwards for next matching tag. This tag
781 replaces the previous matching tag.
782
783 CTRL-P Search backward for previous matching tag. This tag
784 replaces the previous matching tag.
785
786
787 Completing file names *compl-filename*
788 *i_CTRL-X_CTRL-F*
789 CTRL-X CTRL-F Search for the first file name that starts with the
790 same characters as before the cursor. The matching
791 file name is inserted in front of the cursor.
792 Alphabetic characters and characters in 'isfname'
793 are used to decide which characters are included in
794 the file name. Note: the 'path' option is not used
795 here (yet).
796 CTRL-F or
797 CTRL-N Search forwards for next matching file name. This
798 file name replaces the previous matching file name.
799
800 CTRL-P Search backward for previous matching file name.
801 This file name replaces the previous matching file
802 name.
803
804
805 Completing definitions or macros *compl-define*
806
807 The 'define' option is used to specify a line that contains a definition.
808 The 'include' option is used to specify a line that contains an include file
809 name. The 'path' option is used to search for include files.
810
811 *i_CTRL-X_CTRL-D*
812 CTRL-X CTRL-D Search in the current and included files for the
813 first definition (or macro) name that starts with
814 the same characters as before the cursor. The found
815 definition name is inserted in front of the cursor.
816 CTRL-D or
817 CTRL-N Search forwards for next matching macro name. This
818 macro name replaces the previous matching macro
819 name.
820
821 CTRL-P Search backward for previous matching macro name.
822 This macro name replaces the previous matching macro
823 name.
824
825 CTRL-X CTRL-D Further use of CTRL-X CTRL-D will copy the words
826 following the previous expansion in other contexts
827 unless a double CTRL-X is used.
828
829
830 Completing Vim commands *compl-vim*
831
832 Completion is context-sensitive. It works like on the Command-line. It
833 completes an Ex command as well as its arguments.
834
835 *i_CTRL-X_CTRL-V*
836 CTRL-X CTRL-V Guess what kind of item is in front of the cursor and
837 find the first match for it.
838 Note: When CTRL-V is mapped you can often use CTRL-Q
839 instead |i_CTRL-Q|.
840 CTRL-V or
841 CTRL-N Search forwards for next match. This match replaces
842 the previous one.
843
844 CTRL-P Search backward for previous match. This match
845 replaces the previous one.
846
847 CTRL-X CTRL-V Further use of CTRL-X CTRL-V will do the same as
848 CTRL-V. This allows mapping a key to do Vim command
849 completion, for example: >
850 :imap <Tab> <C-X><C-V>
851
852 Completing keywords from different sources *compl-generic*
853
854 *i_CTRL-N*
855 CTRL-N Find next match for words that start with the
856 keyword in front of the cursor, looking in places
857 specified with the 'complete' option. The found
858 keyword is inserted in front of the cursor.
859
860 *i_CTRL-P*
861 CTRL-P Find previous match for words that start with the
862 keyword in front of the cursor, looking in places
863 specified with the 'complete' option. The found
864 keyword is inserted in front of the cursor.
865
866 CTRL-N Search forward for next matching keyword. This
867 keyword replaces the previous matching keyword.
868
869 CTRL-P Search backwards for next matching keyword. This
870 keyword replaces the previous matching keyword.
871
872 CTRL-X CTRL-N or
873 CTRL-X CTRL-P Further use of CTRL-X CTRL-N or CTRL-X CTRL-P will
874 copy the words following the previous expansion in
875 other contexts unless a double CTRL-X is used.
876
877 ==============================================================================
878 8. Insert mode commands *inserting*
879
880 The following commands can be used to insert new text into the buffer. They
881 can all be undone and repeated with the "." command.
882
883 *a*
884 a Append text after the cursor [count] times. If the
885 cursor is in the first column of an empty line Insert
886 starts there. But not when 'virtualedit' is set!
887
888 *A*
889 A Append text at the end of the line [count] times.
890
891 <insert> or *i* *insert* *<Insert>*
892 i Insert text before the cursor [count] times.
893 When using CTRL-O in Insert mode |i_CTRL-O| the count
894 is not supported.
895
896 *I*
897 I Insert text before the first non-blank in the line
898 [count] times.
899
900 *gI*
901 gI Insert text in column 1 [count] times. {not in Vi}
902
903 *gi*
904 gi Insert text in the same position as where Insert mode
905 was stopped last time in the current buffer.
906 This uses the |'^| mark. It's different from "`^i"
907 when the mark is past the end of the line.
908 The position is corrected for inserted/deleted lines,
909 but NOT for inserted/deleted characters.
910 When the |:keepjumps| command modifier is used the |'^|
911 mark wont be changed.
912 {not in Vi}
913
914 *o*
915 o Begin a new line below the cursor and insert text,
916 repeat [count] times. {Vi: blank [count] screen
917 lines}
918
919 *O*
920 O Begin a new line above the cursor and insert text,
921 repeat [count] times. {Vi: blank [count] screen
922 lines}
923
924 These commands are used to start inserting text. You can end insert mode with
925 <Esc>. See |mode-ins-repl| for the other special characters in Insert mode.
926 The effect of [count] takes place after Insert mode is exited.
927
928 When 'autoindent' is on, the indent for a new line is obtained from the
929 previous line. When 'smartindent' or 'cindent' is on, the indent for a line
930 is automatically adjusted for C programs.
931
932 'textwidth' can be set to the maximum width for a line. When a line becomes
933 too long when appending characters a line break is automatically inserted.
934
935
936 ==============================================================================
937 9. Ex insert commands *inserting-ex*
938
939 *:a* *:append*
940 :{range}a[ppend] Insert several lines of text below the specified
941 line. If the {range} is missing, the text will be
942 inserted after the current line.
943
944 *:i* *:in* *:insert*
945 :{range}i[nsert] Insert several lines of text above the specified
946 line. If the {range} is missing, the text will be
947 inserted before the current line.
948
949 These two commands will keep on asking for lines, until you type a line
950 containing only a ".". Watch out for lines starting with a backslash, see
951 |line-continuation|.
952 NOTE: ":append" and ":insert" don't work properly in between ":if" and
953 ":endif".
954
955 *:start* *:startinsert*
956 :star[tinsert][!] Start Insert mode just after executing this command.
957 Works like typing "i" in Normal mode. When the ! is
958 included it works like "A", append to the line.
959 Otherwise insertion starts at the cursor position.
960 Note that when using this command in a function or
961 script, the insertion only starts after the function
962 or script is finished.
963 {not in Vi}
964 {not available when compiled without the +ex_extra
965 feature}
966
967 *:stopi* *:stopinsert*
968 :stopi[nsert] Stop Insert mode as soon as possible. Works like
969 typing <Esc> in Insert mode.
970 Can be used in an autocommand, example: >
971 :au BufEnter scratch stopinsert
972
973 ==============================================================================
974 10. Inserting a file *inserting-file*
975
976 *:r* *:re* *:read*
977 :r[ead] [name] Insert the file [name] (default: current file) below
978 the cursor.
979
980 :{range}r[ead] [name] Insert the file [name] (default: current file) below
981 the specified line.
982
983 *:r!* *:read!*
984 :r[ead] !{cmd} Execute {cmd} and insert its standard output below
985 the cursor. A temporary file is used to store the
986 output of the command which is then read into the
987 buffer. 'shellredir' is used to save the output of
988 the command, which can be set to include stderr or
989 not. {cmd} is executed like with ":!{cmd}", any '!'
990 is replaced with the previous command |:!|.
991
992 These commands insert the contents of a file, or the output of a command,
993 into the buffer. They can be undone. They cannot be repeated with the "."
994 command. They work on a line basis, insertion starts below the line in which
995 the cursor is, or below the specified line. To insert text above the first
996 line use the command ":0r {name}".
997
998 After the ":read" command, the cursor is left on the first non-blank in the
999 first new line. Unless in Ex mode, then the cursor is left on the last new
1000 line (sorry, this is Vi compatible).
1001
1002 If a file name is given with ":r", it becomes the alternate file. This can be
1003 used, for example, when you want to edit that file instead: ":e! #". This can
1004 be switched off by removing the 'a' flag from the 'cpoptions' option.
1005
1006 *file-read*
1007 The 'fileformat' option sets the <EOL> style for a file:
1008 'fileformat' characters name ~
1009 "dos" <CR><NL> or <NL> DOS format
1010 "unix" <NL> Unix format
1011 "mac" <CR> Mac format
1012 Previously 'textmode' was used. It is obsolete now.
1013
1014 If 'fileformat' is "dos", a <CR> in front of an <NL> is ignored and a CTRL-Z
1015 at the end of the file is ignored.
1016
1017 If 'fileformat' is "mac", a <NL> in the file is internally represented by a
1018 <CR>. This is to avoid confusion with a <NL> which is used to represent a
1019 <NUL>. See |CR-used-for-NL|.
1020
1021 If the 'fileformats' option is not empty Vim tries to recognize the type of
1022 <EOL> (see |file-formats|). However, the 'fileformat' option will not be
1023 changed, the detected format is only used while reading the file.
1024 A similar thing happens with 'fileencodings'.
1025
1026 On non-MS-DOS, Win32, and OS/2 systems the message "[dos format]" is shown if
1027 a file is read in DOS format, to remind you that something unusual is done.
1028 On Macintosh, MS-DOS, Win32, and OS/2 the message "[unix format]" is shown if
1029 a file is read in Unix format.
1030 On non-Macintosh systems, the message "[Mac format]" is shown if a file is
1031 read in Mac format.
1032
1033 An example on how to use ":r !": >
1034 :r !uuencode binfile binfile
1035 This command reads "binfile", uuencodes it and reads it into the current
1036 buffer. Useful when you are editing e-mail and want to include a binary
1037 file.
1038
1039 *read-messages*
1040 When reading a file Vim will display a message with information about the read
1041 file. In the table is an explanation for some of the items. The others are
1042 self explanatory. Using the long or the short version depends on the
1043 'shortmess' option.
1044
1045 long short meaning ~
1046 [readonly] {RO} the file is write protected
1047 [fifo/socket] using a stream
1048 [fifo] using a fifo stream
1049 [socket] using a socket stream
1050 [CR missing] reading with "dos" 'fileformat' and a
1051 NL without a preceding CR was found.
1052 [NL found] reading with "mac" 'fileformat' and a
1053 NL was found (could be "unix" format)
1054 [long lines split] at least one line was split in two
1055 [NOT converted] conversion from 'fileencoding' to
1056 'encoding' was desired but not
1057 possible
