| 19 1. Introduction *intro* | |
| 20 | |
| 21 Vim stands for Vi IMproved. It used to be Vi IMitation, but there are so many | |
| 22 improvements that a name change was appropriate. Vim is a text editor which | |
| 23 includes almost all the commands from the Unix program "Vi" and a lot of new | |
| 24 ones. It is very useful for editing programs and other plain text. | |
| 25 All commands are given with the keyboard. This has the advantage that you | |
| 26 can keep your fingers on the keyboard and your eyes on the screen. For those | |
| 27 who want it, there is mouse support and a GUI version with scrollbars and | |
| 28 menus (see |gui.txt|). | |
| 29 | |
| 30 An overview of this manual can be found in the file "help.txt", |help.txt|. | |
| 31 It can be accessed from within Vim with the <Help> or <F1> key and with the | |
| 32 |:help| command (just type ":help", without the bars or quotes). | |
| 33 The 'helpfile' option can be set to the name of the help file, in case it | |
| 34 is not located in the default place. You can jump to subjects like with tags: | |
| 35 Use CTRL-] to jump to a subject under the cursor, use CTRL-T to jump back. | |

37 The differences between Vi and Vim are mentioned in |vi_diff.txt|. |
| 7 | 38 |
| 39 This manual refers to Vim on various machines. There may be small differences | |
| 40 between different computers and terminals. Besides the remarks given in this | |
| 41 document, there is a separate document for each supported system, see | |

| 7 | 48 This manual is a reference for all the Vim commands and options. This is not |
| 49 an introduction to the use of Vi or Vim, it gets a bit complicated here and | |
| 50 there. For beginners, there is a hands-on |tutor|. To learn using Vim, read | |
| 51 the user manual |usr_toc.txt|. | |

| 15334 | 144 Send me patches if you can! If you create a pull request on |
| 145 https://github.com/vim/vim then the automated checks will run and report any | |
| 146 obvious problems. But you can also send the patch by email (use an attachment | |
| 147 to avoid white space changes). | |

| 502 | 149 It will help to include information about the version of Vim you are using and |
| 150 your setup. You can get the information with this command: > | |
| 7 | 151 :so $VIMRUNTIME/bugreport.vim |
| 152 This will create a file "bugreport.txt" in the current directory, with a lot | |
| 153 of information of your environment. Before sending this out, check if it | |
| 154 doesn't contain any confidential information! | |
| 155 | |
| 502 | 156 If Vim crashes, please try to find out where. You can find help on this here: |
| 157 |debug.txt|. | |

| 502 | 159 In case of doubt or when you wonder if the problem has already been fixed but |
| 160 you can't find a fix for it, become a member of the vim-dev maillist and ask | |
| 161 your question there. |maillist| | |
| 7 | 162 |
| 163 *year-2000* *Y2K* | |
| 164 Since Vim internally doesn't use dates for editing, there is no year 2000 | |
| 165 problem to worry about. Vim does use the time in the form of seconds since | |
| 166 January 1st 1970. It is used for a time-stamp check of the edited file and | |
| 167 the swap file, which is not critical and should only cause warning messages. | |
| 168 | |
| 169 There might be a year 2038 problem, when the seconds don't fit in a 32 bit int | |
| 170 anymore. This depends on the compiler, libraries and operating system. | |
| 171 Specifically, time_t and the ctime() function are used. And the time_t is | |
| 172 stored in four bytes in the swap file. But that's only used for printing a | |
| 173 file date/time for recovery, it will never affect normal editing. | |
| 174 | |
| 175 The Vim strftime() function directly uses the strftime() system function. | |
| 176 localtime() uses the time() system function. getftime() uses the time | |
| 177 returned by the stat() system function. If your system libraries are year | |
| 178 2000 compliant, Vim is too. | |
| 179 | |
| 180 The user may create scripts for Vim that use external commands. These might | |
| 181 introduce Y2K problems, but those are not really part of Vim itself. | |

| 273 In this documentation there are several references to other versions of Vi: | |
| 39 | 274 *Vi* *vi* |
| 7 | 275 Vi "the original". Without further remarks this is the version |
| 276 of Vi that appeared in Sun OS 4.x. ":version" returns | |
| 277 "Version 3.7, 6/7/85". Sometimes other versions are referred | |
| 15512 | 278 to. Only runs under Unix. Source code is now available under a |
| 279 BSD-style license. More information on Vi can be found through: | |
| 280 http://ex-vi.sourceforge.net/ | |
| 7 | 281 *Posix* |
| 282 Posix From the IEEE standard 1003.2, Part 2: Shell and utilities. | |
| 283 Generally known as "Posix". This is a textual description of | |
| 284 how Vi is supposed to work. | |
| 161 | 285 See |posix-compliance|. |
| 7 | 286 *Nvi* |
| 287 Nvi The "New" Vi. The version of Vi that comes with BSD 4.4 and FreeBSD. | |
| 288 Very good compatibility with the original Vi, with a few extensions. | |
| 289 The version used is 1.79. ":version" returns "Version 1.79 | |
| 290 (10/23/96)". There has been no release the last few years, although | |
| 291 there is a development version 1.81. | |
| 292 Source code is freely available. | |
| 293 *Elvis* | |
| 294 Elvis Another Vi clone, made by Steve Kirkendall. Very compact but isn't | |
| 15512 | 295 as flexible as Vim. Development has stalled, Elvis has left the |
| 296 building! Source code is freely available. | |
| 297 *Neovim* | |
| 298 Neovim A Vim clone. Forked the Vim source in 2014 and went a different way. | |
| 15334 | 299 Very much bound to github and has many more dependencies, making |
| 300 development more complex and limiting portability. Code has been | |
| 301 refactored, resulting in patches not being exchangeable with Vim. | |
| 302 Supports a remote GUI and integration with scripting languages. | |
| 7 | 303 |
| 304 ============================================================================== | |
| 305 4. Notation *notation* | |
| 306 | |
| 307 When syntax highlighting is used to read this, text that is not typed | |
| 308 literally is often highlighted with the Special group. These are items in [], | |
| 309 {} and <>, and CTRL-X. | |
| 310 | |
| 311 Note that Vim uses all possible characters in commands. Sometimes the [], {} | |
| 312 and <> are part of what you type, the context should make this clear. | |
| 313 | |
| 314 | |
| 315 [] Characters in square brackets are optional. | |
| 316 | |
| 2596 | 317 *count* *[count]* |
| 7 | 318 [count] An optional number that may precede the command to multiply |
| 319 or iterate the command. If no number is given, a count of one | |
| 320 is used, unless otherwise noted. Note that in this manual the | |
| 321 [count] is not mentioned in the description of the command, | |
| 322 but only in the explanation. This was done to make the | |
| 323 commands easier to look up. If the 'showcmd' option is on, | |
| 324 the (partially) entered count is shown at the bottom of the | |
| 325 window. You can use <Del> to erase the last digit (|N<Del>|). | |
| 326 | |
| 327 *[quotex]* | |
| 328 ["x] An optional register designation where text can be stored. | |
| 329 See |registers|. The x is a single character between 'a' and | |
| 330 'z' or 'A' and 'Z' or '"', and in some cases (with the put | |
| 237 | 331 command) between '0' and '9', '%', '#', or others. The |
| 7 | 332 uppercase and lowercase letter designate the same register, |
| 333 but the lowercase letter is used to overwrite the previous | |
| 334 register contents, while the uppercase letter is used to | |
| 237 | 335 append to the previous register contents. Without the ""x" or |
| 7 | 336 with """" the stored text is put into the unnamed register. |
| 337 | |
| 338 *{}* | |
| 339 {} Curly braces denote parts of the command which must appear, | |
| 340 but which can take a number of different values. The | |
| 341 differences between Vim and Vi are also given in curly braces | |
| 342 (this will be clear from the context). | |
| 343 | |
| 344 *{char1-char2}* | |
| 345 {char1-char2} A single character from the range char1 to char2. For | |
| 346 example: {a-z} is a lowercase letter. Multiple ranges may be | |
| 347 concatenated. For example, {a-zA-Z0-9} is any alphanumeric | |
| 348 character. | |
| 349 | |
| 36 | 350 *{motion}* *movement* |
| 7 | 351 {motion} A command that moves the cursor. These are explained in |
| 352 |motion.txt|. Examples: | |
| 353 w to start of next word | |
| 354 b to begin of current word | |
| 355 4j four lines down | |
| 356 /The<CR> to next occurrence of "The" | |
| 357 This is used after an |operator| command to move over the text | |
| 358 that is to be operated upon. | |
| 359 - If the motion includes a count and the operator also has a | |
| 360 count, the two counts are multiplied. For example: "2d3w" | |
| 361 deletes six words. | |
| 362 - The motion can be backwards, e.g. "db" to delete to the | |
| 363 start of the word. | |
| 364 - The motion can also be a mouse click. The mouse is not | |
| 365 supported in every terminal though. | |
| 366 - The ":omap" command can be used to map characters while an | |
| 367 operator is pending. | |
| 368 - Ex commands can be used to move the cursor. This can be | |
| 369 used to call a function that does some complicated motion. | |
| 370 The motion is always characterwise exclusive, no matter | |
| 371 what ":" command is used. This means it's impossible to | |
| 372 include the last character of a line without the line break | |
| 373 (unless 'virtualedit' is set). | |
| 374 If the Ex command changes the text before where the operator | |
| 375 starts or jumps to another buffer the result is | |
| 376 unpredictable. It is possible to change the text further | |
| 377 down. Jumping to another buffer is possible if the current | |
| 378 buffer is not unloaded. | |
| 379 | |
| 380 *{Visual}* | |
| 381 {Visual} A selected text area. It is started with the "v", "V", or | |
| 382 CTRL-V command, then any cursor movement command can be used | |
| 383 to change the end of the selected text. | |
| 384 This is used before an |operator| command to highlight the | |
| 385 text that is to be operated upon. | |
| 386 See |Visual-mode|. | |
| 387 | |
| 388 *<character>* | |
| 389 <character> A special character from the table below, optionally with | |
| 390 modifiers, or a single ASCII character with modifiers. | |
| 391 | |
| 392 *'character'* | |
| 393 'c' A single ASCII character. | |
| 394 | |
| 395 *CTRL-{char}* | |
| 396 CTRL-{char} {char} typed as a control character; that is, typing {char} | |
| 397 while holding the CTRL key down. The case of {char} does not | |
| 398 matter; thus CTRL-A and CTRL-a are equivalent. But on some | |
| 399 terminals, using the SHIFT key will produce another code, | |
| 400 don't use it then. | |
| 401 | |
| 402 *'option'* | |
| 403 'option' An option, or parameter, that can be set to a value, is | |
| 404 enclosed in single quotes. See |options|. | |
| 405 | |
| 406 *quotecommandquote* | |
| 407 "command" A reference to a command that you can type is enclosed in | |
| 408 double quotes. | |
| 4119 | 409 `command` New style command, this distinguishes it from other quoted |
| 410 text and strings. | |
| 7 | 411 |
| 412 *key-notation* *key-codes* *keycodes* | |
| 413 These names for keys are used in the documentation. They can also be used | |
| 414 with the ":map" command (insert the key name by pressing CTRL-K and then the | |
| 415 key you want the name for). | |
| 416 | |

| 475 <t_xx> key with "xx" entry in termcap | |
| 476 ----------------------------------------------------------------------- | |
| 477 | |
| 478 Note: The shifted cursor keys, the help key, and the undo key are only | |
| 479 available on a few terminals. On the Amiga, shifted function key 10 produces | |
| 480 a code (CSI) that is also used by key sequences. It will be recognized only | |
| 481 after typing another key. | |
| 482 | |
| 483 Note: There are two codes for the delete key. 127 is the decimal ASCII value | |
| 484 for the delete key, which is always recognized. Some delete keys send another | |
| 485 value, in which case this value is obtained from the termcap entry "kD". Both | |
| 486 values have the same effect. Also see |:fixdel|. | |
| 487 | |
| 488 Note: The keypad keys are used in the same way as the corresponding "normal" | |
| 489 keys. For example, <kHome> has the same effect as <Home>. If a keypad key | |
| 490 sends the same raw key code as its non-keypad equivalent, it will be | |
| 491 recognized as the non-keypad code. For example, when <kHome> sends the same | |
| 492 code as <Home>, when pressing <kHome> Vim will think <Home> was pressed. | |
| 493 Mapping <kHome> will not work then. | |
| 494 | |
| 495 *<>* | |
| 496 Examples are often given in the <> notation. Sometimes this is just to make | |
| 497 clear what you need to type, but often it can be typed literally, e.g., with | |
| 498 the ":map" command. The rules are: | |
| 499 1. Any printable characters are typed directly, except backslash and '<' | |
| 500 2. A backslash is represented with "\\", double backslash, or "<Bslash>". | |
| 501 3. A real '<' is represented with "\<" or "<lt>". When there is no | |
| 502 confusion possible, a '<' can be used directly. | |
| 503 4. "<key>" means the special key typed. This is the notation explained in | |
| 504 the table above. A few examples: | |
| 505 <Esc> Escape key | |
| 506 <C-G> CTRL-G | |
| 507 <Up> cursor up key | |
| 508 <C-LeftMouse> Control- left mouse click | |
| 509 <S-F11> Shifted function key 11 | |
| 510 <M-a> Meta- a ('a' with bit 8 set) | |
| 511 <M-A> Meta- A ('A' with bit 8 set) | |
| 512 <t_kd> "kd" termcap entry (cursor down key) | |
| 17758 | 513 Although you can specify <M-{char}> with {char} being a multi-byte |
| 514 character, Vim may not be able to know what byte sequence that is and then | |
| 515 it won't work. | |
| 7 | 516 |
| 517 If you want to use the full <> notation in Vim, you have to make sure the '<' | |
| 518 flag is excluded from 'cpoptions' (when 'compatible' is not set, it already is | |
| 519 by default). > | |
| 520 :set cpo-=< | |
| 521 The <> notation uses <lt> to escape the special meaning of key names. Using a | |
| 522 backslash also works, but only when 'cpoptions' does not include the 'B' flag. | |
| 523 | |
| 524 Examples for mapping CTRL-H to the six characters "<Home>": > | |
| 525 :imap <C-H> \<Home> | |
| 526 :imap <C-H> <lt>Home> | |
| 527 The first one only works when the 'B' flag is not in 'cpoptions'. The second | |
| 528 one always works. | |
| 529 To get a literal "<lt>" in a mapping: > | |
| 530 :map <C-L> <lt>lt> | |
| 531 | |
| 532 For mapping, abbreviation and menu commands you can then copy-paste the | |
| 533 examples and use them directly. Or type them literally, including the '<' and | |
| 534 '>' characters. This does NOT work for other commands, like ":set" and | |
| 535 ":autocmd"! | |
| 536 | |
| 537 ============================================================================== | |
| 538 5. Modes, introduction *vim-modes-intro* *vim-modes* | |
| 539 | |
| 12045 | 540 Vim has seven BASIC modes: |
| 7 | 541 |
| 542 *Normal* *Normal-mode* *command-mode* | |
| 543 Normal mode In Normal mode you can enter all the normal editor | |
| 544 commands. If you start the editor you are in this | |
| 545 mode (unless you have set the 'insertmode' option, | |
| 546 see below). This is also known as command mode. | |
| 547 | |
| 548 Visual mode This is like Normal mode, but the movement commands | |
| 549 extend a highlighted area. When a non-movement | |
| 550 command is used, it is executed for the highlighted | |
| 551 area. See |Visual-mode|. | |
| 552 If the 'showmode' option is on "-- VISUAL --" is shown | |
| 553 at the bottom of the window. | |
| 554 | |
| 555 Select mode This looks most like the MS-Windows selection mode. | |
| 556 Typing a printable character deletes the selection | |
| 557 and starts Insert mode. See |Select-mode|. | |
| 558 If the 'showmode' option is on "-- SELECT --" is shown | |
| 559 at the bottom of the window. | |
| 560 | |
| 561 Insert mode In Insert mode the text you type is inserted into the | |
| 562 buffer. See |Insert-mode|. | |
| 563 If the 'showmode' option is on "-- INSERT --" is shown | |
| 564 at the bottom of the window. | |
| 565 | |
| 566 Command-line mode In Command-line mode (also called Cmdline mode) you | |
| 567 Cmdline mode can enter one line of text at the bottom of the | |
| 568 window. This is for the Ex commands, ":", the pattern | |
| 569 search commands, "?" and "/", and the filter command, | |
| 570 "!". |Cmdline-mode| | |
| 571 | |
| 572 Ex mode Like Command-line mode, but after entering a command | |
| 573 you remain in Ex mode. Very limited editing of the | |
| 574 command line. |Ex-mode| | |
| 575 | |
| 12045 | 576 Terminal-Job mode Interacting with a job in a terminal window. Typed |
| 577 keys go to the job and the job output is displayed in | |
| 578 the terminal window. See |terminal| about how to | |
| 579 switch to other modes. | |
| 580 | |
| 11914 | 581 There are seven ADDITIONAL modes. These are variants of the BASIC modes: |
| 7 | 582 |
| 583 *Operator-pending* *Operator-pending-mode* | |
| 584 Operator-pending mode This is like Normal mode, but after an operator | |
| 585 command has started, and Vim is waiting for a {motion} | |
| 586 to specify the text that the operator will work on. | |
| 587 | |
| 588 Replace mode Replace mode is a special case of Insert mode. You | |
| 589 can do the same things as in Insert mode, but for | |
| 590 each character you enter, one character of the existing | |
| 591 text is deleted. See |Replace-mode|. | |
| 592 If the 'showmode' option is on "-- REPLACE --" is | |
| 593 shown at the bottom of the window. | |
| 594 | |
| 1624 | 595 Virtual Replace mode Virtual Replace mode is similar to Replace mode, but |
| 596 instead of file characters you are replacing screen | |
| 597 real estate. See |Virtual-Replace-mode|. | |
| 598 If the 'showmode' option is on "-- VREPLACE --" is | |
| 599 shown at the bottom of the window. | |
| 600 | |
| 14519 | 601 Insert Normal mode Entered when CTRL-O is typed in Insert mode (see |
| 602 |i_CTRL-O|). This is like Normal mode, but after | |
| 603 executing one command Vim returns to Insert mode. | |
| 7 | 604 If the 'showmode' option is on "-- (insert) --" is |
| 605 shown at the bottom of the window. | |
| 606 | |
| 12045 | 607 Terminal-Normal mode Using Normal mode in a terminal window. Making |
| 608 changes is impossible. Use an insert command, such as | |
| 609 "a" or "i", to return to Terminal-Job mode. | |
| 11914 | 610 |
| 7 | 611 Insert Visual mode Entered when starting a Visual selection from Insert |
| 612 mode, e.g., by using CTRL-O and then "v", "V" or | |
| 613 CTRL-V. When the Visual selection ends, Vim returns | |
| 614 to Insert mode. | |
| 615 If the 'showmode' option is on "-- (insert) VISUAL --" | |
| 616 is shown at the bottom of the window. | |
| 617 | |
| 618 Insert Select mode Entered when starting Select mode from Insert mode. | |
| 619 E.g., by dragging the mouse or <S-Right>. | |
| 620 When the Select mode ends, Vim returns to Insert mode. | |
| 621 If the 'showmode' option is on "-- (insert) SELECT --" | |
| 622 is shown at the bottom of the window. | |
| 623 | |
| 624 ============================================================================== | |
| 625 6. Switching from mode to mode *mode-switching* | |
| 626 | |
| 627 If for any reason you do not know which mode you are in, you can always get | |
| 628 back to Normal mode by typing <Esc> twice. This doesn't work for Ex mode | |
| 629 though, use ":visual". | |
| 630 You will know you are back in Normal mode when you see the screen flash or | |
| 631 hear the bell after you type <Esc>. However, when pressing <Esc> after using | |
| 632 CTRL-O in Insert mode you get a beep but you are still in Insert mode, type | |
| 633 <Esc> again. | |
| 634 | |
| 635 *i_esc* | |
| 636 TO mode ~ | |
| 637 Normal Visual Select Insert Replace Cmd-line Ex ~ | |
| 638 FROM mode ~ | |
| 1624 | 639 Normal v V ^V *4 *1 R gR : / ? ! Q |
| 7 | 640 Visual *2 ^G c C -- : -- |
| 641 Select *5 ^O ^G *6 -- -- -- | |
| 642 Insert <Esc> -- -- <Insert> -- -- | |
| 643 Replace <Esc> -- -- <Insert> -- -- | |
| 644 Command-line *3 -- -- :start -- -- | |
| 645 Ex :vi -- -- -- -- -- | |
| 646 | |
| 647 -- not possible | |
| 648 | |
| 649 *1 Go from Normal mode to Insert mode by giving the command "i", "I", "a", | |
| 650 "A", "o", "O", "c", "C", "s" or S". | |
| 651 *2 Go from Visual mode to Normal mode by giving a non-movement command, which | |
| 652 causes the command to be executed, or by hitting <Esc> "v", "V" or "CTRL-V" | |
| 653 (see |v_v|), which just stops Visual mode without side effects. | |
| 654 *3 Go from Command-line mode to Normal mode by: | |
| 655 - Hitting <CR> or <NL>, which causes the entered command to be executed. | |
| 656 - Deleting the complete line (e.g., with CTRL-U) and giving a final <BS>. | |
| 657 - Hitting CTRL-C or <Esc>, which quits the command-line without executing | |
| 658 the command. | |
| 659 In the last case <Esc> may be the character defined with the 'wildchar' | |
| 660 option, in which case it will start command-line completion. You can | |
| 16610 | 661 ignore that and type <Esc> again. |
| 7 | 662 *4 Go from Normal to Select mode by: |
| 663 - use the mouse to select text while 'selectmode' contains "mouse" | |
| 664 - use a non-printable command to move the cursor while keeping the Shift | |
| 665 key pressed, and the 'selectmode' option contains "key" | |
| 666 - use "v", "V" or "CTRL-V" while 'selectmode' contains "cmd" | |
| 667 - use "gh", "gH" or "g CTRL-H" |g_CTRL-H| | |
| 668 *5 Go from Select mode to Normal mode by using a non-printable command to move | |
| 669 the cursor, without keeping the Shift key pressed. | |
| 670 *6 Go from Select mode to Insert mode by typing a printable character. The | |
| 671 selection is deleted and the character is inserted. | |
| 672 | |
| 673 If the 'insertmode' option is on, editing a file will start in Insert mode. | |
| 674 | |
| 675 *CTRL-\_CTRL-N* *i_CTRL-\_CTRL-N* *c_CTRL-\_CTRL-N* *v_CTRL-\_CTRL-N* | |
| 676 Additionally the command CTRL-\ CTRL-N or <C-\><C-N> can be used to go to | |
| 677 Normal mode from any other mode. This can be used to make sure Vim is in | |
| 678 Normal mode, without causing a beep like <Esc> would. However, this does not | |
| 679 work in Ex mode. When used after a command that takes an argument, such as | |
| 680 |f| or |m|, the timeout set with 'ttimeoutlen' applies. | |
| 12045 | 681 When focus is in a terminal window, CTRL-\ CTRL-N goes to Normal mode for only |
| 682 one command, see |t_CTRL-\_CTRL-N|. | |
| 7 | 683 |
| 684 *CTRL-\_CTRL-G* *i_CTRL-\_CTRL-G* *c_CTRL-\_CTRL-G* *v_CTRL-\_CTRL-G* | |
| 685 The command CTRL-\ CTRL-G or <C-\><C-G> can be used to go to Insert mode when | |
| 686 'insertmode' is set. Otherwise it goes to Normal mode. This can be used to | |
| 687 make sure Vim is in the mode indicated by 'insertmode', without knowing in | |
| 688 what mode Vim currently is. | |
| 689 | |
| 690 *Q* *mode-Ex* *Ex-mode* *Ex* *EX* *E501* | |
| 691 Q Switch to "Ex" mode. This is a bit like typing ":" | |
| 692 commands one after another, except: | |
| 693 - You don't have to keep pressing ":". | |
| 694 - The screen doesn't get updated after each command. | |
| 695 - There is no normal command-line editing. | |
| 696 - Mappings and abbreviations are not used. | |
| 697 In fact, you are editing the lines with the "standard" | |
| 698 line-input editing commands (<Del> or <BS> to erase, | |
| 699 CTRL-U to kill the whole line). | |
| 700 Vim will enter this mode by default if it's invoked as | |
| 701 "ex" on the command-line. | |
| 702 Use the ":vi" command |:visual| to exit "Ex" mode. | |
| 703 Note: In older versions of Vim "Q" formatted text, | |
| 704 that is now done with |gq|. But if you use the | |
| 705 |vimrc_example.vim| script "Q" works like "gq". | |
| 706 | |
| 707 *gQ* | |
| 161 | 708 gQ Switch to "Ex" mode like with "Q", but really behave |
| 709 like typing ":" commands after another. All command | |
| 710 line editing, completion etc. is available. | |
| 7 | 711 Use the ":vi" command |:visual| to exit "Ex" mode. |
| 712 | |
| 713 ============================================================================== | |
| 714 7. The window contents *window-contents* | |
| 715 | |
| 716 In Normal mode and Insert/Replace mode the screen window will show the current | |
| 717 contents of the buffer: What You See Is What You Get. There are two | |
| 718 exceptions: | |
| 719 - When the 'cpoptions' option contains '$', and the change is within one line, | |
| 720 the text is not directly deleted, but a '$' is put at the last deleted | |
| 721 character. | |
| 722 - When inserting text in one window, other windows on the same text are not | |
| 723 updated until the insert is finished. | |
| 724 | |
| 725 Lines longer than the window width will wrap, unless the 'wrap' option is off | |
| 726 (see below). The 'linebreak' option can be set to wrap at a blank character. | |
| 727 | |
| 728 If the window has room after the last line of the buffer, Vim will show '~' in | |
| 2642 | 729 the first column of the last lines in the window, like this: |
| 7 | 730 |
| 731 +-----------------------+ | |
| 732 |some line | | |
| 733 |last line | | |
| 734 |~ | | |
| 735 |~ | | |
| 736 +-----------------------+ | |
| 737 | |
| 738 Thus the '~' lines indicate that the end of the buffer was reached. | |
| 739 | |
| 740 If the last line in a window doesn't fit, Vim will indicate this with a '@' in | |
| 2642 | 741 the first column of the last lines in the window, like this: |
| 7 | 742 |
| 743 +-----------------------+ | |
| 744 |first line | | |
| 745 |second line | | |
| 746 |@ | | |
| 747 |@ | | |
| 748 +-----------------------+ | |
| 749 | |
| 750 Thus the '@' lines indicate that there is a line that doesn't fit in the | |
| 751 window. | |
| 752 | |
| 753 When the "lastline" flag is present in the 'display' option, you will not see | |
| 754 '@' characters at the left side of window. If the last line doesn't fit | |
| 755 completely, only the part that fits is shown, and the last three characters of | |
| 2662 | 756 the last line are replaced with "@@@", like this: |
| 7 | 757 |
| 758 +-----------------------+ | |
| 759 |first line | | |
| 760 |second line | | |
| 761 |a very long line that d| | |
| 762 |oesn't fit in the wi@@@| | |
| 763 +-----------------------+ | |
| 764 | |
| 765 If there is a single line that is too long to fit in the window, this is a | |
| 766 special situation. Vim will show only part of the line, around where the | |
| 767 cursor is. There are no special characters shown, so that you can edit all | |
| 768 parts of this line. | |
| 769 | |
| 770 The '@' occasion in the 'highlight' option can be used to set special | |
| 771 highlighting for the '@' and '~' characters. This makes it possible to | |
| 772 distinguish them from real characters in the buffer. | |
| 773 | |
| 774 The 'showbreak' option contains the string to put in front of wrapped lines. | |
| 775 | |
| 776 *wrap-off* | |
| 777 If the 'wrap' option is off, long lines will not wrap. Only the part that | |
| 778 fits on the screen is shown. If the cursor is moved to a part of the line | |
| 779 that is not shown, the screen is scrolled horizontally. The advantage of | |
| 780 this method is that columns are shown as they are and lines that cannot fit | |
| 781 on the screen can be edited. The disadvantage is that you cannot see all the | |
| 782 characters of a line at once. The 'sidescroll' option can be set to the | |
| 16610 | 783 minimal number of columns to scroll. |
| 7 | 784 |
| 785 All normal ASCII characters are displayed directly on the screen. The <Tab> | |
| 786 is replaced with the number of spaces that it represents. Other non-printing | |
| 787 characters are replaced with "^{char}", where {char} is the non-printing | |
| 788 character with 64 added. Thus character 7 (bell) will be shown as "^G". | |
| 789 Characters between 127 and 160 are replaced with "~{char}", where {char} is | |
| 790 the character with 64 subtracted. These characters occupy more than one | |
| 791 position on the screen. The cursor can only be positioned on the first one. | |
| 792 | |
| 793 If you set the 'number' option, all lines will be preceded with their | |
| 794 number. Tip: If you don't like wrapping lines to mix with the line numbers, | |
| 795 set the 'showbreak' option to eight spaces: | |
| 796 ":set showbreak=\ \ \ \ \ \ \ \ " | |
| 797 | |
| 798 If you set the 'list' option, <Tab> characters will not be shown as several | |
| 799 spaces, but as "^I". A '$' will be placed at the end of the line, so you can | |
| 800 find trailing blanks. | |
| 801 | |
| 802 In Command-line mode only the command-line itself is shown correctly. The | |
| 803 display of the buffer contents is updated as soon as you go back to Command | |
| 804 mode. | |
| 805 | |
| 806 The last line of the window is used for status and other messages. The | |
| 807 status messages will only be used if an option is on: | |
| 808 | |
| 809 status message option default Unix default ~ | |
| 810 current mode 'showmode' on on | |
| 811 command characters 'showcmd' on off | |
| 812 cursor position 'ruler' off off | |
| 813 | |
| 814 The current mode is "-- INSERT --" or "-- REPLACE --", see |'showmode'|. The | |
| 16610 | 815 command characters are those that you typed but were not used yet. |
| 7 | 816 |
| 817 If you have a slow terminal you can switch off the status messages to speed | |
| 818 up editing: | |
| 819 :set nosc noru nosm | |
| 820 | |
| 821 If there is an error, an error message will be shown for at least one second | |
| 16610 | 822 (in reverse video). |
| 7 | 823 |
| 824 Some commands show how many lines were affected. Above which threshold this | |
| 825 happens can be controlled with the 'report' option (default 2). | |
| 826 | |
| 827 On the Amiga Vim will run in a CLI window. The name Vim and the full name of | |
| 828 the current file name will be shown in the title bar. When the window is | |
| 829 resized, Vim will automatically redraw the window. You may make the window as | |
| 830 small as you like, but if it gets too small not a single line will fit in it. | |
| 831 Make it at least 40 characters wide to be able to read most messages on the | |
| 832 last line. | |
| 833 | |
| 834 On most Unix systems, resizing the window is recognized and handled correctly | |
| 16610 | 835 by Vim. |

| 838 8. Definitions *definitions* | |
| 839 | |
| 12254 | 840 buffer Contains lines of text, usually read from a file. |
| 7 | 841 screen The whole area that Vim uses to work in. This can be |
| 842 a terminal emulator window. Also called "the Vim | |
| 843 window". | |
| 12254 | 844 window A view on a buffer. There can be multiple windows for |
| 845 one buffer. | |
| 7 | 846 |
| 847 A screen contains one or more windows, separated by status lines and with the | |
| 848 command line at the bottom. | |
| 849 | |

| 859 |command line | | |
| 860 +-------------------------------+ | |
| 861 | |
| 862 The command line is also used for messages. It scrolls up the screen when | |
| 863 there is not enough room in the command line. | |
| 864 | |
| 865 A difference is made between four types of lines: | |
| 866 | |
| 867 buffer lines The lines in the buffer. This is the same as the | |
| 868 lines as they are read from/written to a file. They | |
| 869 can be thousands of characters long. | |
| 870 logical lines The buffer lines with folding applied. Buffer lines | |
| 871 in a closed fold are changed to a single logical line: | |
| 872 "+-- 99 lines folded". They can be thousands of | |
| 873 characters long. | |
| 874 window lines The lines displayed in a window: A range of logical | |
| 875 lines with wrapping, line breaks, etc. applied. They | |
| 876 can only be as long as the width of the window allows, | |
| 877 longer lines are wrapped or truncated. | |
| 878 screen lines The lines of the screen that Vim uses. Consists of | |
| 879 the window lines of all windows, with status lines | |
| 880 and the command line added. They can only be as long | |
| 881 as the width of the screen allows. When the command | |
| 882 line gets longer it wraps and lines are scrolled to | |
| 883 make room. | |
| 884 | |
