9Visual mode is a flexible and easy way to select a piece of text for an
10operator.  It is the only way to select a block of text.
11
12This is introduced in section |04.4| of the user manual.

25==============================================================================
261. Using Visual mode					*visual-use*
27
28Using Visual mode consists of three parts:
291. Mark the start of the text with "v", "V" or CTRL-V.
30   The character under the cursor will be used as the start.
312. Move to the end of the text.
32   The text from the start of the Visual mode up to and including the
33   character under the cursor is highlighted.
343. Type an operator command.
35   The highlighted characters will be operated upon.
36
37The 'highlight' option can be used to set the display mode to use for
38highlighting in Visual mode.
39The 'virtualedit' option can be used to allow positioning the cursor to
40positions where there is no actual character.
41
42The highlighted text normally includes the character under the cursor.
43However, when the 'selection' option is set to "exclusive" and the cursor is
44after the Visual area, the character under the cursor is not included.
45
46With "v" the text before the start position and after the end position will
47not be highlighted.  However, all uppercase and non-alpha operators, except
48"~" and "U", will work on whole lines anyway.  See the list of operators
49below.
50
51							*visual-block*
52With CTRL-V (blockwise Visual mode) the highlighted text will be a rectangle
53between start position and the cursor.  However, some operators work on whole
54lines anyway (see the list below).  The change and substitute operators will
55delete the highlighted text and then start insertion at the top left
56position.
57
58==============================================================================
592. Starting and stopping Visual mode			*visual-start*
60
61						*v* *characterwise-visual*
62[count]v		Start Visual mode per character.
63			With [count] select the same number of characters or
64			lines as used for the last Visual operation, but at
65			the current cursor position, multiplied by [count].
66			When the previous Visual operation was on a block both
67			the width and height of the block are multiplied by
68			[count].
69			When there was no previous Visual operation [count]
70			characters are selected.  This is like moving the
71			cursor right N * [count] characters.  One less when
72			'selection' is not "exclusive".
73
74						*V* *linewise-visual*
75[count]V		Start Visual mode linewise.
76			With [count] select the same number of lines as used
77			for the last Visual operation, but at the current
78			cursor position, multiplied by [count].  When there
79			was no previous Visual operation [count] lines are
80			selected.
81
82						*CTRL-V* *blockwise-visual*
83[count]CTRL-V		Start Visual mode blockwise.  Note: Under Windows
84			CTRL-V could be mapped to paste text, it doesn't work
85			to start Visual mode then, see |CTRL-V-alternative|.
86			[count] is used as with `v` above.
87
88If you use <Esc>, click the left mouse button or use any command that
89does a jump to another buffer while in Visual mode, the highlighting stops
90and no text is affected.  Also when you hit "v" in characterwise Visual mode,
91"CTRL-V" in blockwise Visual mode or "V" in linewise Visual mode.  If you hit
92CTRL-Z the highlighting stops and the editor is suspended or a new shell is
93started |CTRL-Z|.
94
95	      new mode after typing:		*v_v* *v_CTRL-V* *v_V*
96old mode	     "v"	      "CTRL-V"		     "V"	~
97
98Normal		    Visual	   blockwise Visual	  linewise Visual
99Visual		    Normal	   blockwise Visual	  linewise Visual
100blockwise Visual    Visual	   Normal		  linewise Visual
101linewise Visual     Visual	   blockwise Visual	  Normal
102
103						*gv* *v_gv* *reselect-Visual*
104gv			Start Visual mode with the same area as the previous
105			area and the same mode.
106			In Visual mode the current and the previous Visual
107			area are exchanged.
108			After using "p" or "P" in Visual mode the text that
109			was put will be selected.
110
111								*gn* *v_gn*
112gn			Search forward for the last used search pattern, like
113			with `n`, and start Visual mode to select the match.
114			If the cursor is on the match, visually selects it.
115			If an operator is pending, operates on the match.
116			E.g., "dgn" deletes the text of the next match.
117			If Visual mode is active, extends the selection
118			until the end of the next match.
119			'wrapscan' applies
120			Note: Unlike `n` the search direction does not depend
121			on the previous search command.
122
123								*gN* *v_gN*
124gN			Like |gn| but searches backward, like with `N`.
125
126							*<LeftMouse>*
127<LeftMouse>		Set the current cursor position.  If Visual mode is
128			active it is stopped.  Only when 'mouse' option
129			contains 'n' or 'a'.  If the position is within 'so'
130			lines from the last line on the screen the text is
131			scrolled up.  If the position is within 'so' lines from
132			the first line on the screen the text is scrolled
133			down.
134
135							*<RightMouse>*
136<RightMouse>		Start Visual mode if it is not active.  The text from
137			the cursor position to the position of the click is
138			highlighted.  If Visual mode was already active move
139			the start or end of the highlighted text, whichever
140			is closest, to the position of the click.  Only when
141			'mouse' option contains 'n' or 'a'.
142
143			Note: when 'mousemodel' is set to "popup",
144			<S-LeftMouse> has to be used instead of <RightMouse>.
145
146							*<LeftRelease>*
147<LeftRelease>		This works like a <LeftMouse>, if it is not at
148			the same position as <LeftMouse>.  In an older version
149			of xterm you won't see the selected area until the
150			button is released, unless there is access to the
151			display where the xterm is running (via the DISPLAY
152			environment variable or the -display argument).  Only
153			when 'mouse' option contains 'n' or 'a'.
154
155If Visual mode is not active and the "v", "V" or CTRL-V is preceded with a
156count, the size of the previously highlighted area is used for a start.  You
157can then move the end of the highlighted area and give an operator.  The type
158of the old area is used (character, line or blockwise).
159- Linewise Visual mode: The number of lines is multiplied with the count.
160- Blockwise Visual mode: The number of lines and columns is multiplied with
161  the count.
162- Normal Visual mode within one line: The number of characters is multiplied
163  with the count.
164- Normal Visual mode with several lines: The number of lines is multiplied
165  with the count, in the last line the same number of characters is used as
166  in the last line in the previously highlighted area.
167The start of the text is the Cursor position.  If the "$" command was used as
168one of the last commands to extend the highlighted text, the area will be
169extended to the rightmost column of the longest line.
170
171If you want to highlight exactly the same area as the last time, you can use
172"gv" |gv| |v_gv|.
173
174							*v_<Esc>*
175<Esc>			In Visual mode: Stop Visual mode.
176
177							*v_CTRL-C*
178CTRL-C			In Visual mode: Stop Visual mode.  When insert mode is
179			pending (the mode message shows
180			"-- (insert) VISUAL --"), it is also stopped.
181
182==============================================================================
1833. Changing the Visual area				*visual-change*
184
185							*v_o*
186o			Go to Other end of highlighted text: The current
187			cursor position becomes the start of the highlighted
188			text and the cursor is moved to the other end of the
189			highlighted text.  The highlighted area remains the
190			same.
191
192							*v_O*
193O			Go to Other end of highlighted text.  This is like
194			"o", but in Visual block mode the cursor moves to the
195			other corner in the same line.  When the corner is at
196			a character that occupies more than one position on
197			the screen (e.g., a <Tab>), the highlighted text may
198			change.
199
200							*v_$*
201When the "$" command is used with blockwise Visual mode, the right end of the
202highlighted text will be determined by the longest highlighted line.  This
203stops when a motion command is used that does not move straight up or down.
204
205For moving the end of the block many commands can be used, but you cannot
206use Ex commands, commands that make changes or abandon the file.  Commands
207(starting with) ".", "&", CTRL-^, "Z", CTRL-], CTRL-T, CTRL-R, CTRL-I
208and CTRL-O cause a beep and Visual mode continues.
209
210When switching to another window on the same buffer, the cursor position in
211that window is adjusted, so that the same Visual area is still selected.  This
212is especially useful to view the start of the Visual area in one window, and
213the end in another.  You can then use <RightMouse> (or <S-LeftMouse> when
214'mousemodel' is "popup") to drag either end of the Visual area.
215
216==============================================================================
2174. Operating on the Visual area				*visual-operators*
218
219The operators that can be used are:
220	~	switch case					|v_~|
221	d	delete						|v_d|
222	c	change (4)					|v_c|
223	y	yank						|v_y|
224	>	shift right (4)					|v_>|
225	<	shift left (4)					|v_<|
226	!	filter through external command (1)		|v_!|
227	=	filter through 'equalprg' option command (1)	|v_=|
228	gq	format lines to 'textwidth' length (1)		|v_gq|
229
230The objects that can be used are:
231	aw	a word (with white space)			|v_aw|
232	iw	inner word					|v_iw|
233	aW	a WORD (with white space)			|v_aW|
234	iW	inner WORD					|v_iW|
235	as	a sentence (with white space)			|v_as|
236	is	inner sentence					|v_is|
237	ap	a paragraph (with white space)			|v_ap|
238	ip	inner paragraph					|v_ip|
239	ab	a () block (with parentheses)			|v_ab|
240	ib	inner () block					|v_ib|
241	aB	a {} block (with braces)			|v_aB|
242	iB	inner {} block					|v_iB|
243	at	a <tag> </tag> block (with tags)		|v_at|
244	it	inner <tag> </tag> block			|v_it|
245	a<	a <> block (with <>)				|v_a<|
246	i<	inner <> block					|v_i<|
247	a[	a [] block (with [])				|v_a[|
248	i[	inner [] block					|v_i[|
249	a"	a double quoted string (with quotes)		|v_aquote|
250	i"	inner double quoted string			|v_iquote|
251	a'	a single quoted string (with quotes)		|v_a'|
252	i'	inner simple quoted string			|v_i'|
253	a`	a string in backticks (with backticks)		|v_a`|
254	i`	inner string in backticks			|v_i`|
255
256Additionally the following commands can be used:
257	:	start Ex command for highlighted lines (1)	|v_:|
258	r	change (4)					|v_r|
259	s	change						|v_s|
260	C	change (2)(4)					|v_C|
261	S	change (2)					|v_S|
262	R	change (2)					|v_R|
263	x	delete						|v_x|
264	D	delete (3)					|v_D|
265	X	delete (2)					|v_X|
266	Y	yank (2)					|v_Y|
267	p	put						|v_p|
268	J	join (1)					|v_J|
269	U	make uppercase					|v_U|
270	u	make lowercase					|v_u|
271	^]	find tag					|v_CTRL-]|
272	I	block insert					|v_b_I|
273	A	block append					|v_b_A|
274
275(1): Always whole lines, see |:visual_example|.
276(2): Whole lines when not using CTRL-V.
277(3): Whole lines when not using CTRL-V, delete until the end of the line when
278     using CTRL-V.
279(4): When using CTRL-V operates on the block only.
280
281Note that the ":vmap" command can be used to specifically map keys in Visual
282mode.  For example, if you would like the "/" command not to extend the Visual
283area, but instead take the highlighted text and search for that: >
284	:vmap / y/<C-R>"<CR>
285(In the <> notation |<>|, when typing it you should type it literally; you
286need to remove the 'B' and '<' flags from 'cpoptions'.)
287
288If you want to give a register name using the """ command, do this just before
289typing the operator character: "v{move-around}"xd".
290
291If you want to give a count to the command, do this just before typing the
292operator character: "v{move-around}3>" (move lines 3 indents to the right).
293
294							*{move-around}*
295The {move-around} is any sequence of movement commands.  Note the difference
296with {motion}, which is only ONE movement command.
297
298Another way to operate on the Visual area is using the |/\%V| item in a
299pattern.  For example, to replace all '(' in the Visual area with '#': >
300
301	:'<,'>s/\%V(/#/g
302
303Note that the "'<,'>" will appear automatically when you press ":" in Visual
304mode.
305
306==============================================================================
3075. Blockwise operators					*blockwise-operators*
308
309Reminder: Use 'virtualedit' to be able to select blocks that start or end
310after the end of a line or halfway a tab.
311
312Visual-block Insert						*v_b_I*
313With a blockwise selection, I{string}<ESC> will insert {string} at the start
314of block on every line of the block, provided that the line extends into the
315block.  Thus lines that are short will remain unmodified.  TABs are split to
316retain visual columns.  Works only for adding text to a line, not for
317deletions.  See |v_b_I_example|.
318
319Visual-block Append						*v_b_A*
320With a blockwise selection, A{string}<ESC> will append {string} to the end of
321block on every line of the block.  There is some differing behavior where the
322block RHS is not straight, due to different line lengths:
323
3241. Block was created with <C-v>$
325    In this case the string is appended to the end of each line.
3262. Block was created with <C-v>{move-around}
327    In this case the string is appended to the end of the block on each line,
328    and whitespace is inserted to pad to the end-of-block column.
329See |v_b_A_example|.
330Note: "I" and "A" behave differently for lines that don't extend into the
331selected block.  This was done intentionally, so that you can do it the way
332you want.
333Works only for adding text to a line, not for deletions.
334
335Visual-block change						*v_b_c*
336All selected text in the block will be replaced by the same text string.  When
337using "c" the selected text is deleted and Insert mode started.  You can then
338enter text (without a line break).  When you hit <Esc>, the same string is
339inserted in all previously selected lines.
340
341Visual-block Change						*v_b_C*
342Like using "c", but the selection is extended until the end of the line for
343all lines.
344
345								*v_b_<*
346Visual-block Shift						*v_b_>*
347The block is shifted by 'shiftwidth'.  The RHS of the block is irrelevant.  The
348LHS of the block determines the point from which to apply a right shift, and
349padding includes TABs optimally according to 'ts' and 'et'.  The LHS of the
350block determines the point up to which to shift left.
351See |v_b_>_example|.
352See |v_b_<_example|.
353
354Visual-block Replace						*v_b_r*
355Every screen char in the highlighted region is replaced with the same char, ie
356TABs are split and the virtual whitespace is replaced, maintaining screen
357layout.
358See |v_b_r_example|.
359
360
361==============================================================================
3626. Repeating						*visual-repeat*
363
364When repeating a Visual mode operator, the operator will be applied to the
365same amount of text as the last time:
366- Linewise Visual mode: The same number of lines.
367- Blockwise Visual mode: The same number of lines and columns.
368- Normal Visual mode within one line: The same number of characters.
369- Normal Visual mode with several lines: The same number of lines, in the
370  last line the same number of characters as in the last line the last time.
371The start of the text is the Cursor position.  If the "$" command was used as
372one of the last commands to extend the highlighted text, the repeating will
373be applied up to the rightmost column of the longest line.
374
375
376==============================================================================
3777. Examples						*visual-examples*
378
379							*:visual_example*
380Currently the ":" command works on whole lines only.  When you select part of
381a line, doing something like ":!date" will replace the whole line.  If you
382want only part of the line to be replaced you will have to make a mapping for
383it.  In a future release ":" may work on partial lines.
384
385Here is an example, to replace the selected text with the output of "date": >
386	:vmap _a <Esc>`>a<CR><Esc>`<i<CR><Esc>!!date<CR>kJJ
387
388(In the <> notation |<>|, when typing it you should type it literally; you
389need to remove the 'B' and '<' flags from 'cpoptions')
390
391What this does is:
392<Esc>		stop Visual mode
393`>		go to the end of the Visual area
394a<CR><Esc>	break the line after the Visual area
395`<		jump to the start of the Visual area
396i<CR><Esc>	break the line before the Visual area
397!!date<CR>	filter the Visual text through date
398kJJ		Join the lines back together
399
400							*visual-search*
401Here is an idea for a mapping that makes it possible to do a search for the
402selected text: >
403	:vmap X y/<C-R>"<CR>
404
405(In the <> notation |<>|, when typing it you should type it literally; you
406need to remove the 'B' and '<' flags from 'cpoptions')
407
408Note that special characters (like '.' and '*') will cause problems.
409
410Visual-block Examples					*blockwise-examples*
411With the following text, I will indicate the commands to produce the block and
412the results below.  In all cases, the cursor begins on the 'a' in the first
413line of the test text.
414The following modeline settings are assumed ":ts=8:sw=4:".
415
416It will be helpful to
417:set hls
418/<TAB>
419where <TAB> is a real TAB.  This helps visualise the operations.
420
421The test text is:
422

463==============================================================================
4648. Select mode						*Select* *Select-mode*
465
466Select mode looks like Visual mode, but the commands accepted are quite
467different.  This resembles the selection mode in Microsoft Windows.
468When the 'showmode' option is set, "-- SELECT --" is shown in the last line.
469
470Entering Select mode:
471- Using the mouse to select an area, and 'selectmode' contains "mouse".
472  'mouse' must also contain a flag for the current mode.
473- Using a non-printable movement command, with the Shift key pressed, and
474  'selectmode' contains "key".  For example: <S-Left> and <S-End>.  'keymodel'
475  must also contain "startsel".
476- Using "v", "V" or CTRL-V command, and 'selectmode' contains "cmd".
477- Using "gh", "gH" or "g_CTRL-H" command in Normal mode.
478- From Visual mode, press CTRL-G.			*v_CTRL-G*
479
480Commands in Select mode:
481- Printable characters, <NL> and <CR> cause the selection to be deleted, and
482  Vim enters Insert mode.  The typed character is inserted.
483- Non-printable movement commands, with the Shift key pressed, extend the
484  selection.  'keymodel' must include "startsel".
485- Non-printable movement commands, with the Shift key NOT pressed, stop Select
486  mode.  'keymodel' must include "stopsel".
487- ESC stops Select mode.
488- CTRL-O switches to Visual mode for the duration of one command. *v_CTRL-O*
489- CTRL-G switches to Visual mode.
490
491Otherwise, typed characters are handled as in Visual mode.
492
493When using an operator in Select mode, and the selection is linewise, the
494selected lines are operated upon, but like in characterwise selection.  For
495example, when a whole line is deleted, it can later be pasted halfway a line.
496
497
498Mappings and menus in Select mode.			*Select-mode-mapping*

500When mappings and menus are defined with the |:vmap| or |:vmenu| command they
501work both in Visual mode and in Select mode.  When these are used in Select
502mode Vim automatically switches to Visual mode, so that the same behavior as
503in Visual mode is effective.  If you don't want this use |:xmap| or |:smap|.
504
505Users will expect printable characters to replace the selected area.
506Therefore avoid mapping printable characters in Select mode.  Or use
507|:sunmap|  after |:map| and |:vmap| to remove it for Select mode.
508
509After the mapping or menu finishes, the selection is enabled again and Select
510mode entered, unless the selected area was deleted, another buffer became
511the current one or the window layout was changed.
512
513When a character was typed that causes the selection to be deleted and Insert
514mode started, Insert mode mappings are applied to this character.  This may
515cause some confusion, because it means Insert mode mappings apply to a
516character typed in Select mode.  Language mappings apply as well.

518							*gV* *v_gV*
519gV			Avoid the automatic reselection of the Visual area
520			after a Select mode mapping or menu has finished.
521			Put this just before the end of the mapping or menu.
522			At least it should be after any operations on the
523			selection.
524
525							*gh*
526gh			Start Select mode, characterwise.  This is like "v",
527			but starts Select mode instead of Visual mode.
528			Mnemonic: "get highlighted".
529
530							*gH*
531gH			Start Select mode, linewise.  This is like "V",
532			but starts Select mode instead of Visual mode.
533			Mnemonic: "get Highlighted".
534
535							*g_CTRL-H*
536g CTRL-H		Start Select mode, blockwise.  This is like CTRL-V,
537			but starts Select mode instead of Visual mode.
538			Mnemonic: "get Highlighted".
