   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.
   36 
   37 Throughout this manual the differences between Vi and Vim are mentioned in
   38 curly braces, like this: {Vi does not have on-line help}.  See |vi_diff.txt|
   39 for a summary of the differences between Vim and Vi.
   40 
   41 This manual refers to Vim on various machines.  There may be small differences
   42 between different computers and terminals.  Besides the remarks given in this
   43 document, there is a separate document for each supported system, see
   44 |sys-file-list|.
   45 
   46 This manual is a reference for all the Vim commands and options.  This is not
   47 an introduction to the use of Vi or Vim, it gets a bit complicated here and
   48 there.  For beginners, there is a hands-on |tutor|.  To learn using Vim, read
   49 the user manual |usr_toc.txt|.
   50 
   51 							*book*
   52 There are many books on Vi that contain a section for beginners.  There are
   53 two books I can recommend:
   54 
   55 	"Vim - Vi Improved" by Steve Oualline
   56 
   57 This is the very first book completely dedicated to Vim.  It is very good for
   58 beginners.  The most often used commands are explained with pictures and
   59 examples.  The less often used commands are also explained, the more advanced
   60 features are summarized.  There is a comprehensive index and a quick
   61 reference.  Parts of this book have been included in the user manual
   62 |frombook|.

   66 	http://www.vim.org/iccf/click5.html
   67 
   68 	"Learning the Vi editor" by Linda Lamb and Arnold Robbins
   69 
   70 This is a book about Vi that includes a chapter on Vim (in the sixth edition).
   71 The first steps in Vi are explained very well.  The commands that Vim adds are
   72 only briefly mentioned.  There is also a German translation.
   73 Published by O'Reilly.  ISBN: 1-56592-426-6.

   90 This group is also for other editors.  If you write about Vim, don't forget to
   91 mention that.
   92 
   93 						*mail-list* *maillist*
   94 There are several mailing lists for Vim:
   95 <vim@vim.org>
   96 	For discussions about using existing versions of Vim: Useful mappings,
   97 	questions, answers, where to get a specific version, etc.  There are
   98 	quite a few people watching this list and answering questions, also
   99 	for beginners.  Don't hesitate to ask your question here.
  100 <vim-dev@vim.org>				*vim-dev* *vimdev*
  101 	For discussions about changing Vim: New features, porting, patches,
  102 	beta-test versions, etc.
  103 <vim-announce@vim.org>				*vim-announce*
  104 	Announcements about new versions of Vim; also for beta-test versions
  105 	and ports to different systems.  This is a read-only list.
  106 <vim-multibyte@vim.org>				*vim-multibyte*
  107 	For discussions about using and improving the multi-byte aspects of
  108 	Vim.

  132 Bug reports:				*bugs* *bug-reports* *bugreport.vim*
  133 
  134 Send bug reports to: Vim bugs <bugs@vim.org>
  135 This is not a maillist but the message is redirected to the Vim maintainer.
  136 Please be brief; all the time that is spent on answering mail is subtracted
  137 from the time that is spent on improving Vim!  Always give a reproducible
  138 example and try to find out which settings or other things influence the
  139 appearance of the bug.  Try different machines, if possible.  Send me patches
  140 if you can!
  141 
  142 It will help to include information about the version of Vim you are using and
  143 your setup.  You can get the information with this command: >
  144    :so $VIMRUNTIME/bugreport.vim
  145 This will create a file "bugreport.txt" in the current directory, with a lot
  146 of information of your environment.  Before sending this out, check if it
  147 doesn't contain any confidential information!
  148 
  149 If Vim crashes, please try to find out where.  You can find help on this here:
  150 |debug.txt|.
  151 
  152 In case of doubt or when you wonder if the problem has already been fixed but
  153 you can't find a fix for it, become a member of the vim-dev maillist and ask
  154 your question there. |maillist|
  155 
  156 							*year-2000* *Y2K*
  157 Since Vim internally doesn't use dates for editing, there is no year 2000
  158 problem to worry about.  Vim does use the time in the form of seconds since
  159 January 1st 1970.  It is used for a time-stamp check of the edited file and
  160 the swap file, which is not critical and should only cause warning messages.
  161 
  162 There might be a year 2038 problem, when the seconds don't fit in a 32 bit int
  163 anymore.  This depends on the compiler, libraries and operating system.
  164 Specifically, time_t and the ctime() function are used.  And the time_t is
  165 stored in four bytes in the swap file.  But that's only used for printing a
  166 file date/time for recovery, it will never affect normal editing.
  167 
  168 The Vim strftime() function directly uses the strftime() system function.
  169 localtime() uses the time() system function.  getftime() uses the time
  170 returned by the stat() system function.  If your system libraries are year
  171 2000 compliant, Vim is too.
  172 
  173 The user may create scripts for Vim that use external commands.  These might
  174 introduce Y2K problems, but those are not really part of Vim itself.

  257 
  258 
  259 In this documentation there are several references to other versions of Vi:
  260 							*Vi* *vi*
  261 Vi	"the original".  Without further remarks this is the version
  262 	of Vi that appeared in Sun OS 4.x.  ":version" returns
  263 	"Version 3.7, 6/7/85".  Sometimes other versions are referred
  264 	to.  Only runs under Unix.  Source code only available with a
  265 	license.  More information on Vi can be found through:
  266 		http://vi-editor.org	[doesn't currently work...]
  267 							*Posix*
  268 Posix	From the IEEE standard 1003.2, Part 2: Shell and utilities.
  269 	Generally known as "Posix".  This is a textual description of
  270 	how Vi is supposed to work.
  271 	See |posix-compliance|.
  272 							*Nvi*
  273 Nvi	The "New" Vi.  The version of Vi that comes with BSD 4.4 and FreeBSD.
  274 	Very good compatibility with the original Vi, with a few extensions.
  275 	The version used is 1.79.  ":version" returns "Version 1.79
  276 	(10/23/96)".  There has been no release the last few years, although
  277 	there is a development version 1.81.
  278 	Source code is freely available.
  279 							*Elvis*
  280 Elvis	Another Vi clone, made by Steve Kirkendall.  Very compact but isn't
  281 	as flexible as Vim.
  282 	The version used is 2.1.  It is still being developed.  Source code is
  283 	freely available.
  284 
  285 ==============================================================================
  286 4. Notation						*notation*
  287 
  288 When syntax highlighting is used to read this, text that is not typed
  289 literally is often highlighted with the Special group.  These are items in [],
  290 {} and <>, and CTRL-X.
  291 
  292 Note that Vim uses all possible characters in commands.  Sometimes the [], {}
  293 and <> are part of what you type, the context should make this clear.
  294 
  295 
  296 []		Characters in square brackets are optional.
  297 
  298 						    *count* *[count]* *E489*
  299 [count]		An optional number that may precede the command to multiply
  300 		or iterate the command.  If no number is given, a count of one
  301 		is used, unless otherwise noted.  Note that in this manual the
  302 		[count] is not mentioned in the description of the command,
  303 		but only in the explanation.  This was done to make the
  304 		commands easier to look up.  If the 'showcmd' option is on,
  305 		the (partially) entered count is shown at the bottom of the
  306 		window.  You can use <Del> to erase the last digit (|N<Del>|).
  307 
  308 							*[quotex]*
  309 ["x]		An optional register designation where text can be stored.
  310 		See |registers|.  The x is a single character between 'a' and
  311 		'z' or 'A' and 'Z' or '"', and in some cases (with the put
  312 		command) between '0' and '9', '%', '#', or others.  The
  313 		uppercase and lowercase letter designate the same register,
  314 		but the lowercase letter is used to overwrite the previous
  315 		register contents, while the uppercase letter is used to
  316 		append to the previous register contents.  Without the ""x" or
  317 		with """" the stored text is put into the unnamed register.
  318 
  319 							*{}*
  320 {}		Curly braces denote parts of the command which must appear,
  321 		but which can take a number of different values.  The
  322 		differences between Vim and Vi are also given in curly braces
  323 		(this will be clear from the context).
  324 
  325 							*{char1-char2}*
  326 {char1-char2}	A single character from the range char1 to char2.  For
  327 		example: {a-z} is a lowercase letter.  Multiple ranges may be
  328 		concatenated.  For example, {a-zA-Z0-9} is any alphanumeric
  329 		character.
  330 
  331 						*{motion}* *movement*
  332 {motion}	A command that moves the cursor.  These are explained in
  333 		|motion.txt|.  Examples:
  334 			w		to start of next word
  335 			b		to begin of current word
  336 			4j		four lines down
  337 			/The<CR>	to next occurrence of "The"
  338 		This is used after an |operator| command to move over the text
  339 		that is to be operated upon.
  340 		- If the motion includes a count and the operator also has a
  341 		  count, the two counts are multiplied.  For example: "2d3w"
  342 		  deletes six words.
  343 		- The motion can be backwards, e.g. "db" to delete to the
  344 		  start of the word.
  345 		- The motion can also be a mouse click.  The mouse is not
  346 		  supported in every terminal though.
  347 		- The ":omap" command can be used to map characters while an
  348 		  operator is pending.
  349 		- Ex commands can be used to move the cursor.  This can be
  350 		  used to call a function that does some complicated motion.
  351 		  The motion is always characterwise exclusive, no matter
  352 		  what ":" command is used.  This means it's impossible to
  353 		  include the last character of a line without the line break
  354 		  (unless 'virtualedit' is set).
  355 		  If the Ex command changes the text before where the operator
  356 		  starts or jumps to another buffer the result is
  357 		  unpredictable.  It is possible to change the text further
  358 		  down.  Jumping to another buffer is possible if the current
  359 		  buffer is not unloaded.
  360 
  361 							*{Visual}*
  362 {Visual}	A selected text area.  It is started with the "v", "V", or
  363 		CTRL-V command, then any cursor movement command can be used
  364 		to change the end of the selected text.
  365 		This is used before an |operator| command to highlight the
  366 		text that is to be operated upon.
  367 		See |Visual-mode|.
  368 
  369 							*<character>*
  370 <character>	A special character from the table below, optionally with
  371 		modifiers, or a single ASCII character with modifiers.
  372 
  373 							*'character'*
  374 'c'		A single ASCII character.
  375 
  376 							*CTRL-{char}*
  377 CTRL-{char}	{char} typed as a control character; that is, typing {char}
  378 		while holding the CTRL key down.  The case of {char} does not
  379 		matter; thus CTRL-A and CTRL-a are equivalent.  But on some
  380 		terminals, using the SHIFT key will produce another code,
  381 		don't use it then.
  382 
  383 							*'option'*
  384 'option'	An option, or parameter, that can be set to a value, is
  385 		enclosed in single quotes.  See |options|.
  386 
  387 							*quotecommandquote*
  388 "command"	A reference to a command that you can type is enclosed in
  389 		double quotes.
  390 
  391 					*key-notation* *key-codes* *keycodes*
  392 These names for keys are used in the documentation.  They can also be used
  393 with the ":map" command (insert the key name by pressing CTRL-K and then the
  394 key you want the name for).

  454 <t_xx>		key with "xx" entry in termcap
  455 -----------------------------------------------------------------------
  456 
  457 Note: The shifted cursor keys, the help key, and the undo key are only
  458 available on a few terminals.  On the Amiga, shifted function key 10 produces
  459 a code (CSI) that is also used by key sequences.  It will be recognized only
  460 after typing another key.
  461 
  462 Note: There are two codes for the delete key.  127 is the decimal ASCII value
  463 for the delete key, which is always recognized.  Some delete keys send another
  464 value, in which case this value is obtained from the termcap entry "kD".  Both
  465 values have the same effect.  Also see |:fixdel|.
  466 
  467 Note: The keypad keys are used in the same way as the corresponding "normal"
  468 keys.  For example, <kHome> has the same effect as <Home>.  If a keypad key
  469 sends the same raw key code as its non-keypad equivalent, it will be
  470 recognized as the non-keypad code.  For example, when <kHome> sends the same
  471 code as <Home>, when pressing <kHome> Vim will think <Home> was pressed.
  472 Mapping <kHome> will not work then.
  473 
  474 								*<>*
  475 Examples are often given in the <> notation.  Sometimes this is just to make
  476 clear what you need to type, but often it can be typed literally, e.g., with
  477 the ":map" command.  The rules are:
  478  1.  Any printable characters are typed directly, except backslash and '<'
  479  2.  A backslash is represented with "\\", double backslash, or "<Bslash>".
  480  3.  A real '<' is represented with "\<" or "<lt>".  When there is no
  481      confusion possible, a '<' can be used directly.
  482  4.  "<key>" means the special key typed.  This is the notation explained in
  483      the table above.  A few examples:
  484 	   <Esc>		Escape key
  485 	   <C-G>		CTRL-G
  486 	   <Up>			cursor up key
  487 	   <C-LeftMouse>	Control- left mouse click
  488 	   <S-F11>		Shifted function key 11
  489 	   <M-a>		Meta- a  ('a' with bit 8 set)
  490 	   <M-A>		Meta- A  ('A' with bit 8 set)
  491 	   <t_kd>		"kd" termcap entry (cursor down key)
  492 
  493 If you want to use the full <> notation in Vim, you have to make sure the '<'
  494 flag is excluded from 'cpoptions' (when 'compatible' is not set, it already is
  495 by default). >
  496 	:set cpo-=<
  497 The <> notation uses <lt> to escape the special meaning of key names.  Using a
  498 backslash also works, but only when 'cpoptions' does not include the 'B' flag.
  499 
  500 Examples for mapping CTRL-H to the six characters "<Home>": >
  501 	:imap <C-H> \<Home>
  502 	:imap <C-H> <lt>Home>
  503 The first one only works when the 'B' flag is not in 'cpoptions'.  The second
  504 one always works.
  505 To get a literal "<lt>" in a mapping: >
  506 	:map <C-L> <lt>lt>
  507 
  508 For mapping, abbreviation and menu commands you can then copy-paste the
  509 examples and use them directly.  Or type them literally, including the '<' and
  510 '>' characters.  This does NOT work for other commands, like ":set" and
  511 ":autocmd"!
  512 
  513 ==============================================================================
  514 5. Modes, introduction				*vim-modes-intro* *vim-modes*
  515 
  516 Vim has six BASIC modes:
  517 
  518 					*Normal* *Normal-mode* *command-mode*
  519 Normal mode		In Normal mode you can enter all the normal editor
  520 			commands.  If you start the editor you are in this
  521 			mode (unless you have set the 'insertmode' option,
  522 			see below).  This is also known as command mode.
  523 
  524 Visual mode		This is like Normal mode, but the movement commands
  525 			extend a highlighted area.  When a non-movement
  526 			command is used, it is executed for the highlighted
  527 			area.  See |Visual-mode|.
  528 			If the 'showmode' option is on "-- VISUAL --" is shown
  529 			at the bottom of the window.
  530 
  531 Select mode		This looks most like the MS-Windows selection mode.
  532 			Typing a printable character deletes the selection
  533 			and starts Insert mode.  See |Select-mode|.
  534 			If the 'showmode' option is on "-- SELECT --" is shown
  535 			at the bottom of the window.
  536 
  537 Insert mode		In Insert mode the text you type is inserted into the
  538 			buffer.  See |Insert-mode|.
  539 			If the 'showmode' option is on "-- INSERT --" is shown
  540 			at the bottom of the window.
  541 
  542 Command-line mode	In Command-line mode (also called Cmdline mode) you
  543 Cmdline mode		can enter one line of text at the bottom of the
  544 			window.  This is for the Ex commands, ":", the pattern
  545 			search commands, "?" and "/", and the filter command,
  546 			"!".  |Cmdline-mode|
  547 
  548 Ex mode			Like Command-line mode, but after entering a command
  549 			you remain in Ex mode.  Very limited editing of the
  550 			command line.  |Ex-mode|
  551 
  552 There are six ADDITIONAL modes.  These are variants of the BASIC modes:
  553 
  554 				*Operator-pending* *Operator-pending-mode*
  555 Operator-pending mode	This is like Normal mode, but after an operator
  556 			command has started, and Vim is waiting for a {motion}
  557 			to specify the text that the operator will work on.
  558 
  559 Replace mode		Replace mode is a special case of Insert mode.  You
  560 			can do the same things as in Insert mode, but for
  561 			each character you enter, one character of the existing
  562 			text is deleted.  See |Replace-mode|.
  563 			If the 'showmode' option is on "-- REPLACE --" is
  564 			shown at the bottom of the window.
  565 
  566 Virtual Replace mode	Virtual Replace mode is similar to Replace mode, but
  567 			instead of file characters you are replacing screen
  568 			real estate.  See |Virtual-Replace-mode|.
  569 			If the 'showmode' option is on "-- VREPLACE --" is
  570 			shown at the bottom of the window.
  571 
  572 Insert Normal mode	Entered when CTRL-O given in Insert mode.  This is
  573 			like Normal mode, but after executing one command Vim
  574 			returns to Insert mode.
  575 			If the 'showmode' option is on "-- (insert) --" is
  576 			shown at the bottom of the window.
  577 
  578 Insert Visual mode	Entered when starting a Visual selection from Insert
  579 			mode, e.g., by using CTRL-O and then "v", "V" or
  580 			CTRL-V.  When the Visual selection ends, Vim returns
  581 			to Insert mode.
  582 			If the 'showmode' option is on "-- (insert) VISUAL --"
  583 			is shown at the bottom of the window.
  584 
  585 Insert Select mode	Entered when starting Select mode from Insert mode.
  586 			E.g., by dragging the mouse or <S-Right>.
  587 			When the Select mode ends, Vim returns to Insert mode.
  588 			If the 'showmode' option is on "-- (insert) SELECT --"
  589 			is shown at the bottom of the window.
  590 
  591 ==============================================================================
  592 6. Switching from mode to mode				*mode-switching*
  593 
  594 If for any reason you do not know which mode you are in, you can always get
  595 back to Normal mode by typing <Esc> twice.  This doesn't work for Ex mode
  596 though, use ":visual".
  597 You will know you are back in Normal mode when you see the screen flash or
  598 hear the bell after you type <Esc>.  However, when pressing <Esc> after using
  599 CTRL-O in Insert mode you get a beep but you are still in Insert mode, type
  600 <Esc> again.
  601 
  602 							*i_esc*
  603 		TO mode						    ~
  604 		Normal	Visual	Select	Insert	  Replace   Cmd-line  Ex ~
  605 FROM mode								 ~
  606 Normal			v V ^V	  *4	 *1	   R gR     : / ? !   Q
  607 Visual		 *2		  ^G	 c C	    --	      :       --
  608 Select		 *5	^O ^G		 *6	    --	      --      --
  609 Insert		 <Esc>	  --	  --		  <Insert>    --      --
  610 Replace		 <Esc>	  --	  --	<Insert>	      --      --
  611 Command-line	 *3	  --	  --	 :start	    --		      --
  612 Ex		 :vi	  --	  --	 --	    --	      --
  613 
  614 -  NA
  615 -- not possible
  616 
  617 *1 Go from Normal mode to Insert mode by giving the command "i", "I", "a",
  618    "A", "o", "O", "c", "C", "s" or S".
  619 *2 Go from Visual mode to Normal mode by giving a non-movement command, which
  620    causes the command to be executed, or by hitting <Esc> "v", "V" or "CTRL-V"
  621    (see |v_v|), which just stops Visual mode without side effects.
  622 *3 Go from Command-line mode to Normal mode by:
  623    - Hitting <CR> or <NL>, which causes the entered command to be executed.
  624    - Deleting the complete line (e.g., with CTRL-U) and giving a final <BS>.
  625    - Hitting CTRL-C or <Esc>, which quits the command-line without executing
  626      the command.
  627    In the last case <Esc> may be the character defined with the 'wildchar'
  628    option, in which case it will start command-line completion.  You can
  629    ignore that and type <Esc> again.  {Vi: when hitting <Esc> the command-line
  630    is executed.  This is unexpected for most people; therefore it was changed
  631    in Vim.  But when the <Esc> is part of a mapping, the command-line is
  632    executed.  If you want the Vi behaviour also when typing <Esc>, use ":cmap
  633    ^V<Esc> ^V^M"}
  634 *4 Go from Normal to Select mode by:
  635    - use the mouse to select text while 'selectmode' contains "mouse"
  636    - use a non-printable command to move the cursor while keeping the Shift
  637      key pressed, and the 'selectmode' option contains "key"
  638    - use "v", "V" or "CTRL-V" while 'selectmode' contains "cmd"
  639    - use "gh", "gH" or "g CTRL-H"  |g_CTRL-H|
  640 *5 Go from Select mode to Normal mode by using a non-printable command to move
  641    the cursor, without keeping the Shift key pressed.
  642 *6 Go from Select mode to Insert mode by typing a printable character.  The
  643    selection is deleted and the character is inserted.
  644 
  645 If the 'insertmode' option is on, editing a file will start in Insert mode.
  646 
  647 	*CTRL-\_CTRL-N* *i_CTRL-\_CTRL-N* *c_CTRL-\_CTRL-N* *v_CTRL-\_CTRL-N*
  648 Additionally the command CTRL-\ CTRL-N or <C-\><C-N> can be used to go to
  649 Normal mode from any other mode.  This can be used to make sure Vim is in
  650 Normal mode, without causing a beep like <Esc> would.  However, this does not
  651 work in Ex mode.  When used after a command that takes an argument, such as
  652 |f| or |m|, the timeout set with 'ttimeoutlen' applies.
  653 
  654 	*CTRL-\_CTRL-G* *i_CTRL-\_CTRL-G* *c_CTRL-\_CTRL-G* *v_CTRL-\_CTRL-G*
  655 The command CTRL-\ CTRL-G or <C-\><C-G> can be used to go to Insert mode when
  656 'insertmode' is set.  Otherwise it goes to Normal mode.  This can be used to
  657 make sure Vim is in the mode indicated by 'insertmode', without knowing in
  658 what mode Vim currently is.
  659 
  660 				    *Q* *mode-Ex* *Ex-mode* *Ex* *EX* *E501*
  661 Q			Switch to "Ex" mode.  This is a bit like typing ":"
  662 			commands one after another, except:
  663 			- You don't have to keep pressing ":".
  664 			- The screen doesn't get updated after each command.
  665 			- There is no normal command-line editing.
  666 			- Mappings and abbreviations are not used.
  667 			In fact, you are editing the lines with the "standard"
  668 			line-input editing commands (<Del> or <BS> to erase,
  669 			CTRL-U to kill the whole line).
  670 			Vim will enter this mode by default if it's invoked as
  671 			"ex" on the command-line.
  672 			Use the ":vi" command |:visual| to exit "Ex" mode.
  673 			Note: In older versions of Vim "Q" formatted text,
  674 			that is now done with |gq|.  But if you use the
  675 			|vimrc_example.vim| script "Q" works like "gq".
  676 
  677 					*gQ*
  678 gQ			Switch to "Ex" mode like with "Q", but really behave
  679 			like typing ":" commands after another.  All command
  680 			line editing, completion etc. is available.
  681 			Use the ":vi" command |:visual| to exit "Ex" mode.
  682 			{not in Vi}
  683 
  684 ==============================================================================
  685 7. The window contents					*window-contents*
  686 
  687 In Normal mode and Insert/Replace mode the screen window will show the current
  688 contents of the buffer: What You See Is What You Get.  There are two
  689 exceptions:
  690 - When the 'cpoptions' option contains '$', and the change is within one line,
  691   the text is not directly deleted, but a '$' is put at the last deleted
  692   character.
  693 - When inserting text in one window, other windows on the same text are not
  694   updated until the insert is finished.
  695 {Vi: The screen is not always updated on slow terminals}
  696 
  697 Lines longer than the window width will wrap, unless the 'wrap' option is off
  698 (see below).  The 'linebreak' option can be set to wrap at a blank character.
  699 
  700 If the window has room after the last line of the buffer, Vim will show '~' in
  701 the first column of the last lines in the window, like this: >
  702 
  703 	+-----------------------+
  704 	|some line		|
  705 	|last line		|
  706 	|~			|
  707 	|~			|
  708 	+-----------------------+
  709 
  710 Thus the '~' lines indicate that the end of the buffer was reached.
  711 
  712 If the last line in a window doesn't fit, Vim will indicate this with a '@' in
  713 the first column of the last lines in the window, like this: >
  714 
  715 	+-----------------------+
  716 	|first line		|
  717 	|second line		|
  718 	|@			|
  719 	|@			|
  720 	+-----------------------+
  721 
  722 Thus the '@' lines indicate that there is a line that doesn't fit in the
  723 window.
  724 
  725 When the "lastline" flag is present in the 'display' option, you will not see
  726 '@' characters at the left side of window.  If the last line doesn't fit
  727 completely, only the part that fits is shown, and the last three characters of
  728 the last line are replaced with "@@@", like this: >
  729 
  730 	+-----------------------+
  731 	|first line		|
  732 	|second line		|
  733 	|a very long line that d|
  734 	|oesn't fit in the wi@@@|
  735 	+-----------------------+
  736 
  737 If there is a single line that is too long to fit in the window, this is a
  738 special situation.  Vim will show only part of the line, around where the
  739 cursor is.  There are no special characters shown, so that you can edit all
  740 parts of this line.
  741 {Vi: gives an "internal error" on lines that do not fit in the window}
  742 
  743 The '@' occasion in the 'highlight' option can be used to set special
  744 highlighting for the '@' and '~' characters.  This makes it possible to
  745 distinguish them from real characters in the buffer.
  746 
  747 The 'showbreak' option contains the string to put in front of wrapped lines.
  748 
  749 							*wrap-off*
  750 If the 'wrap' option is off, long lines will not wrap.  Only the part that
  751 fits on the screen is shown.  If the cursor is moved to a part of the line
  752 that is not shown, the screen is scrolled horizontally.  The advantage of
  753 this method is that columns are shown as they are and lines that cannot fit
  754 on the screen can be edited.  The disadvantage is that you cannot see all the
  755 characters of a line at once.  The 'sidescroll' option can be set to the
  756 minimal number of columns to scroll.  {Vi: has no 'wrap' option}
  757 
  758 All normal ASCII characters are displayed directly on the screen.  The <Tab>
  759 is replaced with the number of spaces that it represents.  Other non-printing
  760 characters are replaced with "^{char}", where {char} is the non-printing
  761 character with 64 added.  Thus character 7 (bell) will be shown as "^G".
  762 Characters between 127 and 160 are replaced with "~{char}", where {char} is
  763 the character with 64 subtracted.  These characters occupy more than one
  764 position on the screen.  The cursor can only be positioned on the first one.
  765 
  766 If you set the 'number' option, all lines will be preceded with their
  767 number.  Tip: If you don't like wrapping lines to mix with the line numbers,
  768 set the 'showbreak' option to eight spaces:
  769 	":set showbreak=\ \ \ \ \ \ \ \ "
  770 
  771 If you set the 'list' option, <Tab> characters will not be shown as several
  772 spaces, but as "^I".  A '$' will be placed at the end of the line, so you can
  773 find trailing blanks.
  774 
  775 In Command-line mode only the command-line itself is shown correctly.  The
  776 display of the buffer contents is updated as soon as you go back to Command
  777 mode.
  778 
  779 The last line of the window is used for status and other messages.  The
  780 status messages will only be used if an option is on:
  781 
  782 status message			option	     default	Unix default	~
  783 current mode			'showmode'	on	    on
  784 command characters		'showcmd'	on	    off
  785 cursor position			'ruler'		off	    off
  786 
  787 The current mode is "-- INSERT --" or "-- REPLACE --", see |'showmode'|.  The
  788 command characters are those that you typed but were not used yet.  {Vi: does
  789 not show the characters you typed or the cursor position}
  790 
  791 If you have a slow terminal you can switch off the status messages to speed
  792 up editing:
  793 	:set nosc noru nosm
  794 
  795 If there is an error, an error message will be shown for at least one second
  796 (in reverse video).  {Vi: error messages may be overwritten with other
  797 messages before you have a chance to read them}
  798 
  799 Some commands show how many lines were affected.  Above which threshold this
  800 happens can be controlled with the 'report' option (default 2).
  801 
  802 On the Amiga Vim will run in a CLI window.  The name Vim and the full name of
  803 the current file name will be shown in the title bar.  When the window is
  804 resized, Vim will automatically redraw the window.  You may make the window as
  805 small as you like, but if it gets too small not a single line will fit in it.
  806 Make it at least 40 characters wide to be able to read most messages on the
  807 last line.
  808 
  809 On most Unix systems, resizing the window is recognized and handled correctly
  810 by Vim.  {Vi: not ok}
  811 
  812 ==============================================================================
  813 8. Definitions						*definitions*
  814 
  815   screen		The whole area that Vim uses to work in.  This can be
  816 			a terminal emulator window.  Also called "the Vim
  817 			window".
  818   window		A view on a buffer.
  819 
  820 A screen contains one or more windows, separated by status lines and with the
  821 command line at the bottom.
  822 
  823 	+-------------------------------+
  824 screen	| window 1	| window 2	|
  825 	|		|		|
  826 	|		|		|
  827 	|= status line =|= status line =|
  828 	| window 3			|
  829 	|				|
  830 	|				|
  831 	|==== status line ==============|
  832 	|command line			|
  833 	+-------------------------------+
  834 
  835 The command line is also used for messages.  It scrolls up the screen when
  836 there is not enough room in the command line.
  837 
  838 A difference is made between four types of lines:
  839 
  840   buffer lines		The lines in the buffer.  This is the same as the
  841 			lines as they are read from/written to a file.  They
  842 			can be thousands of characters long.
