*visual.txt*    For Vim version 7.1.  Last change: 2006 Sep 26  		  VIM REFERENCE MANUAL    by Bram Moolenaar  Visual mode				*Visual* *Visual-mode* *visual-mode* Visual mode is a flexible and easy way to select a piece of text for anoperator.  It is the only way to select a block of text. This is introduced in section |04.4| of the user manual. 1. Using Visual mode			|visual-use|2. Starting and stopping Visual mode	|visual-start|3. Changing the Visual area		|visual-change|4. Operating on the Visual area		|visual-operators|5. Blockwise operators			|blockwise-operators|6. Repeating				|visual-repeat|7. Examples				|visual-examples|8. Select mode				|Select-mode| {Vi has no Visual mode, the name "visual" is used for Normal mode, todistinguish it from Ex mode}{not available when the |+visual| feature was disabled when compiling} ==============================================================================1. Using Visual mode					*visual-use* Using Visual mode consists of three parts:1. Mark the start of the text with "v", "V" or CTRL-V.   The character under the cursor will be used as the start.2. Move to the end of the text.   The text from the start of the Visual mode up to and including the   character under the cursor is highlighted.3. Type an operator command.   The highlighted characters will be operated upon. The 'highlight' option can be used to set the display mode to use forhighlighting in Visual mode.The 'virtualedit' option can be used to allow positioning the cursor topositions where there is no actual character. The highlighted text normally includes the character under the cursor.However, when the 'selection' option is set to "exclusive" and the cursor isafter the Visual area, the character under the cursor is not included. With "v" the text before the start position and after the end position willnot be highlighted.  However, all uppercase and non-alpha operators, except"~" and "U", will work on whole lines anyway.  See the list of operatorsbelow. 							*visual-block*With CTRL-V (blockwise Visual mode) the highlighted text will be a rectanglebetween start position and the cursor.  However, some operators work on wholelines anyway (see the list below).  The change and substitute operators willdelete the highlighted text and then start insertion at the top leftposition. ==============================================================================2. Starting and stopping Visual mode			*visual-start* 						*v* *characterwise-visual*v			start Visual mode per character. 						*V* *linewise-visual*V			start Visual mode linewise. 						*CTRL-V* *blockwise-visual*CTRL-V			start Visual mode blockwise.  Note: Under Windows			CTRL-V could be mapped to paste text, it doesn't work			to start Visual mode then, see |CTRL-V-alternative|. If you use <Esc>, click the left mouse button or use any command thatdoes a jump to another buffer while in Visual mode, the highlighting stopsand no text is affected.  Also when you hit "v" in characterwise Visual mode,"CTRL-V" in blockwise Visual mode or "V" in linewise Visual mode.  If you hitCTRL-Z the highlighting stops and the editor is suspended or a new shell isstarted |CTRL-Z|. 	      new mode after typing:		*v_v* *v_CTRL-V* *v_V*old mode	     "v"	      "CTRL-V"		     "V"	~ Normal		    Visual	   blockwise Visual	  linewise VisualVisual		    Normal	   blockwise Visual	  linewise Visualblockwise Visual    Visual	   Normal		  linewise Visuallinewise Visual     Visual	   blockwise Visual	  Normal 						*gv* *v_gv* *reselect-Visual*gv			Start Visual mode with the same area as the previous			area and the same mode.			In Visual mode the current and the previous Visual			area are exchanged.			After using "p" or "P" in Visual mode the text that			was put will be selected. 							*<LeftMouse>*<LeftMouse>		Set the current cursor position.  If Visual mode is			active it is stopped.  Only when 'mouse' option is			contains 'n' or 'a'.  If the position is within 'so'			lines from the last line on the screen the text is			scrolled up.  If the position is within 'so' lines from			the first line on the screen the text is scrolled			down. 							*<RightMouse>*<RightMouse>		Start Visual mode if it is not active.  The text from			the cursor position to the position of the click is			highlighted.  If Visual mode was already active move			the start or end of the highlighted text, which ever			is closest, to the position of the click.  Only when			'mouse' option contains 'n' or 'a'. 			Note: when 'mousemodel' is set to "popup",			<S-LeftMouse> has to be used instead of <RightMouse>. 							*<LeftRelease>*<LeftRelease>		This works like a <LeftMouse>, if it is not at			the same position as <LeftMouse>.  In an older version			of xterm you won't see the selected area until the			button is released, unless there is access to the			display where the xterm is running (via the DISPLAY			environment variable or the -display argument).  Only			when 'mouse' option contains 'n' or 'a'. If Visual mode is not active and the "v", "V" or CTRL-V is preceded with acount, the size of the previously highlighted area is used for a start.  Youcan then move the end of the highlighted area and give an operator.  The typeof the old area is used (character, line or blockwise).- Linewise Visual mode: The number of lines is multiplied with the count.- Blockwise Visual mode: The number of lines and columns is multiplied with  the count.- Normal Visual mode within one line: The number of characters is multiplied  with the count.- Normal Visual mode with several lines: The number of lines is multiplied  with the count, in the last line the same number of characters is used as  in the last line in the previously highlighted area.The start of the text is the Cursor position.  If the "$" command was used asone of the last commands to extend the highlighted text, the area will beextended to the rightmost column of the longest line. If you want to highlight exactly the same area as the last time, you can use"gv" |gv| |v_gv|. 							*v_<Esc>*<Esc>			In Visual mode: Stop Visual mode. 							*v_CTRL-C*CTRL-C			In Visual mode: Stop Visual mode.  When insert mode is			pending (the mode message shows			"-- (insert) VISUAL --"), it is also stopped. ==============================================================================3. Changing the Visual area				*visual-change* 							*v_o*o			Go to Other end of highlighted text: The current			cursor position becomes the start of the highlighted			text and the cursor is moved to the other end of the			highlighted text.  The highlighted area remains the			same. 							*v_O*O			Go to Other end of highlighted text.  This is like			"o", but in Visual block mode the cursor moves to the			other corner in the same line.  When the corner is at			a character that occupies more than one position on			the screen (e.g., a <Tab>), the highlighted text may			change. 							*v_$*When the "$" command is used with blockwise Visual mode, the right end of thehighlighted text will be determined by the longest highlighted line.  Thisstops when a motion command is used that does not move straight up or down. For moving the end of the block many commands can be used, but you cannotuse Ex commands, commands that make changes or abandon the file.  Commands(starting with) ".", "&", CTRL-^, "Z", CTRL-], CTRL-T, CTRL-R, CTRL-Iand CTRL-O cause a beep and Visual mode continues. When switching to another window on the same buffer, the cursor position inthat window is adjusted, so that the same Visual area is still selected.  Thisis especially useful to view the start of the Visual area in one window, andthe end in another.  You can then use <RightMouse> (or <S-LeftMouse> when'mousemodel' is "popup") to drag either end of the Visual area. ==============================================================================4. Operating on the Visual area				*visual-operators* The operators that can be used are:	~	switch case					|v_~|	d	delete						|v_d|	c	change (4)					|v_c|	y	yank						|v_y|	>	shift right (4)					|v_>|	<	shift left (4)					|v_<|	!	filter through external command (1)		|v_!|	=	filter through 'equalprg' option command (1)	|v_=|	gq	format lines to 'textwidth' length (1)		|v_gq| The objects that can be used are:	aw	a word (with white space)			|v_aw|	iw	inner word					|v_iw|	aW	a WORD (with white space)			|v_aW|	iW	inner WORD					|v_iW|	as	a sentence (with white space)			|v_as|	is	inner sentence					|v_is|	ap	a paragraph (with white space)			|v_ap|	ip	inner paragraph					|v_ip|	ab	a () block (with parenthesis)			|v_ab|	ib	inner () block					|v_ib|	aB	a {} block (with braces)			|v_aB|	iB	inner {} block					|v_iB|	a<	a <> block (with <>)				|v_a<|	i<	inner <> block					|v_i<|	a[	a [] block (with [])				|v_a[|	i[	inner [] block					|v_i[| Additionally the following commands can be used:	:	start ex command for highlighted lines (1)	|v_:|	r	change (4)					|v_r|	s	change						|v_s|	C	change (2)(4)					|v_C|	S	change (2)					|v_S|	R	change (2)					|v_R|	x	delete						|v_x|	D	delete (3)					|v_D|	X	delete (2)					|v_X|	Y	yank (2)					|v_Y|	p	put						|v_p|	J	join (1)					|v_J|	U	make uppercase					|v_U|	u	make lowercase					|v_u|	^]	find tag					|v_CTRL-]|	I	block insert					|v_b_I|	A	block append					|v_b_A| (1): Always whole lines, see |:visual_example|.(2): Whole lines when not using CTRL-V.(3): Whole lines when not using CTRL-V, delete until the end of the line when     using CTRL-V.(4): When using CTRL-V operates on the block only. Note that the ":vmap" command can be used to specifically map keys in Visualmode.  For example, if you would like the "/" command not to extend the Visualarea, but instead take the highlighted text and search for that: >	:vmap / y/<C-R>"<CR>(In the <> notation |<>|, when typing it you should type it literally; youneed to remove the 'B' and '<' flags from 'cpoptions'.) If you want to give a register name using the """ command, do this just beforetyping the operator character: "v{move-around}"xd". If you want to give a count to the command, do this just before typing theoperator character: "v{move-around}3>" (move lines 3 indents to the right). 							*{move-around}*The {move-around} is any sequence of movement commands.  Note the differencewith {motion}, which is only ONE movement command. Another way to operate on the Visual area is using the |/\%V| item in apattern.  For example, to replace all '(' in the Visual area with '#': > 	:%s/\%V(/X/g ==============================================================================5. Blockwise operators					*blockwise-operators* {not available when compiled without the |+visualextra| feature} Reminder: Use 'virtualedit' to be able to select blocks that start or endafter the end of a line or halfway a tab. Visual-block Insert						*v_b_I*With a blockwise selection, I{string}<ESC> will insert {string} at the startof block on every line of the block, provided that the line extends into theblock.  Thus lines that are short will remain unmodified.  TABs are split toretain visual columns.See |v_b_I_example|. Visual-block Append						*v_b_A*With a blockwise selection, A{string}<ESC> will append {string} to the end ofblock on every line of the block.  There is some differing behavior where theblock RHS is not straight, due to different line lengths: 1. Block was created with <C-v>$    In this case the string is appended to the end of each line.2. Block was created with <C-v>{move-around}    In this case the string is appended to the end of the block on each line,    and whitespace is inserted to pad to the end-of-block column.See |v_b_A_example|.Note: "I" and "A" behave differently for lines that don't extend into theselected block.  This was done intentionally, so that you can do it the wayyou want. Visual-block change						*v_b_c*All selected text in the block will be replaced by the same text string.  Whenusing "c" the selected text is deleted and Insert mode started.  You can thenenter text (without a line break).  When you hit <Esc>, the same string isinserted in all previously selected lines. Visual-block Change						*v_b_C*Like using "c", but the selection is extended until the end of the line forall lines. 								*v_b_<*Visual-block Shift						*v_b_>*The block is shifted by 'shiftwidth'.  The RHS of the block is irrelevant.  TheLHS of the block determines the point from which to apply a right shift, andpadding includes TABs optimally according to 'ts' and 'et'.  The LHS of theblock determines the point upto which to shift left.    Note: v_< padding is buggy if the Visual Block starts and ends in the same    TAB. (Vim 5.4c)See |v_b_>_example|.See |v_b_<_example|. Visual-block Replace						*v_b_r*Every screen char in the highlighted region is replaced with the same char, ieTABs are split and the virtual whitespace is replaced, maintaining screenlayout.See |v_b_r_example|.  ==============================================================================6. Repeating						*visual-repeat* When repeating a Visual mode operator, the operator will be applied to thesame amount of text as the last time:- Linewise Visual mode: The same number of lines.- Blockwise Visual mode: The same number of lines and columns.- Normal Visual mode within one line: The same number of characters.- Normal Visual mode with several lines: The same number of lines, in the  last line the same number of characters as in the last line the last time.The start of the text is the Cursor position.  If the "$" command was used asone of the last commands to extend the highlighted text, the repeating willbe applied up to the rightmost column of the longest line.  ==============================================================================7. Examples						*visual-examples* 							*:visual_example*Currently the ":" command works on whole lines only.  When you select part ofa line, doing something like ":!date" will replace the whole line.  If youwant only part of the line to be replaced you will have to make a mapping forit.  In a future release ":" may work on partial lines. Here is an example, to replace the selected text with the output of "date": >	:vmap _a <Esc>`>a<CR><Esc>`<i<CR><Esc>!!date<CR>kJJ (In the <> notation |<>|, when typing it you should type it literally; youneed to remove the 'B' and '<' flags from 'cpoptions') What this does is:<Esc>		stop Visual mode`>		go to the end of the Visual areaa<CR><Esc>	break the line after the Visual area`<		jump to the start of the Visual areai<CR><Esc>	break the line before the Visual area!!date<CR>	filter the Visual text through datekJJ		Join the lines back together 							*visual-search*Here is an idea for a mapping that makes it possible to do a search for theselected text: >	:vmap X y/<C-R>"<CR> (In the <> notation |<>|, when typing it you should type it literally; youneed to remove the 'B' and '<' flags from 'cpoptions') Note that special characters (like '.' and '*') will cause problems. Visual-block Examples					*blockwise-examples*With the following text, I will indicate the commands to produce the block andthe results below.  In all cases, the cursor begins on the 'a' in the firstline of the test text.The following modeline settings are assumed ":ts=8:sw=4:". It will be helpful to:set hls/<TAB>where <TAB> is a real TAB.  This helps visualise the operations. The test text is: abcdefghijklmnopqrstuvwxyzabc		defghijklmnopqrstuvwxyzabcdef  ghi		jklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz 1. fo<C-v>3jISTRING<ESC>					*v_b_I_example* abcdefghijklmnSTRINGopqrstuvwxyzabc	      STRING  defghijklmnopqrstuvwxyzabcdef  ghi   STRING	jklmnopqrstuvwxyzabcdefghijklmnSTRINGopqrstuvwxyz 2. fo<C-v>3j$ASTRING<ESC>					*v_b_A_example* abcdefghijklmnopqrstuvwxyzSTRINGabc		defghijklmnopqrstuvwxyzSTRINGabcdef  ghi		jklmnopqrstuvwxyzSTRINGabcdefghijklmnopqrstuvwxyzSTRING 3. fo<C-v>3j3l<..						*v_b_<_example* abcdefghijklmnopqrstuvwxyzabc	      defghijklmnopqrstuvwxyzabcdef  ghi   jklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz 4. fo<C-v>3j>..							*v_b_>_example* abcdefghijklmn		  opqrstuvwxyzabc			    defghijklmnopqrstuvwxyzabcdef  ghi			    jklmnopqrstuvwxyzabcdefghijklmn		  opqrstuvwxyz 5. fo<C-v>5l3jrX						*v_b_r_example* abcdefghijklmnXXXXXXuvwxyzabc	      XXXXXXhijklmnopqrstuvwxyzabcdef  ghi   XXXXXX    jklmnopqrstuvwxyzabcdefghijklmnXXXXXXuvwxyz ==============================================================================8. Select mode						*Select* *Select-mode* Select mode looks like Visual mode, but the commands accepted are quitedifferent.  This resembles the selection mode in Microsoft Windows.When the 'showmode' option is set, "-- SELECT --" is shown in the last line. Entering Select mode:- Using the mouse to select an area, and 'selectmode' contains "mouse".  'mouse' must also contain a flag for the current mode.- Using a non-printable movement command, with the Shift key pressed, and  'selectmode' contains "key".  For example: <S-Left> and <S-End>.  'keymodel'  must also contain "startsel".- Using "v", "V" or CTRL-V command, and 'selectmode' contains "cmd".- Using "gh", "gH" or "g_CTRL-H" command in Normal mode.- From Visual mode, press CTRL-G.			*v_CTRL-G* Commands in Select mode:- Printable characters, <NL> and <CR> cause the selection to be deleted, and  Vim enters Insert mode.  The typed character is inserted.- Non-printable movement commands, with the Shift key pressed, extend the  selection.  'keymodel' must include "startsel".- Non-printable movement commands, with the Shift key NOT pressed, stop Select  mode.  'keymodel' must include "stopsel".- ESC stops Select mode.- CTRL-O switches to Visual mode for the duration of one command. *v_CTRL-O*- CTRL-G switches to Visual mode. Otherwise, typed characters are handled as in Visual mode. When using an operator in Select mode, and the selection is linewise, theselected lines are operated upon, but like in characterwise selection.  Forexample, when a whole line is deleted, it can later be pasted halfway a line.  Mappings and menus in Select mode.			*Select-mode-mapping* When mappings and menus are defined with the |:vmap| or |:vmenu| command theywork both in Visual mode and in Select mode.  When these are used in Selectmode Vim automatically switches to Visual mode, so that the same behavior asin Visual mode is effective.  If you don't want this use |:xmap| or |:smap|. After the mapping or menu finishes, the selection is enabled again and Selectmode entered, unless the selected area was deleted, another buffer becamethe current one or the window layout was changed. When a character was typed that causes the selection to be deleted and Insertmode started, Insert mode mappings are applied to this character.  This maycause some confusion, because it means Insert mode mappings apply to acharacter typed in Select mode.  Language mappings apply as well. 							*gV* *v_gV*gV			Avoid the automatic reselection of the Visual area			after a Select mode mapping or menu has finished.			Put this just before the end of the mapping or menu.			At least it should be after any operations on the			selection. 							*gh*gh			Start Select mode, characterwise.  This is like "v",			but starts Select mode instead of Visual mode.			Mnemonic: "get highlighted". 							*gH*gH			Start Select mode, linewise.  This is like "V",			but starts Select mode instead of Visual mode.			Mnemonic: "get Highlighted". 							*g_CTRL-H*g CTRL-H		Start Select mode, blockwise.  This is like CTRL-V,			but starts Select mode instead of Visual mode.			Mnemonic: "get Highlighted".  vim:tw=78:ts=8:ft=help:norl:
