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.

26
27==============================================================================
281. Using Visual mode					*visual-use*
29
30Using Visual mode consists of three parts:
311. Mark the start of the text with "v", "V" or CTRL-V.
32   The character under the cursor will be used as the start.
332. Move to the end of the text.
34   The text from the start of the Visual mode up to and including the
35   character under the cursor is highlighted.
363. Type an operator command.
37   The highlighted characters will be operated upon.
38
39The 'highlight' option can be used to set the display mode to use for
40highlighting in Visual mode.
41The 'virtualedit' option can be used to allow positioning the cursor to
42positions where there is no actual character.
43
44The highlighted text normally includes the character under the cursor.
45However, when the 'selection' option is set to "exclusive" and the cursor is
46after the Visual area, the character under the cursor is not included.
47
48With "v" the text before the start position and after the end position will
49not be highlighted.  However, all uppercase and non-alpha operators, except
50"~" and "U", will work on whole lines anyway.  See the list of operators
51below.
52
53							*visual-block*
54With CTRL-V (blockwise Visual mode) the highlighted text will be a rectangle
55between start position and the cursor.  However, some operators work on whole
56lines anyway (see the list below).  The change and substitute operators will
57delete the highlighted text and then start insertion at the top left
58position.
59
60==============================================================================
612. Starting and stopping Visual mode			*visual-start*
62
63						*v* *characterwise-visual*
64v			start Visual mode per character.
65
66						*V* *linewise-visual*
67V			start Visual mode linewise.
68
69						*CTRL-V* *blockwise-visual*
70CTRL-V			start Visual mode blockwise.  Note: Under Windows
71			CTRL-V could be mapped to paste text, it doesn't work
72			to start Visual mode then, see |CTRL-V-alternative|.
73
74If you use <Esc>, click the left mouse button or use any command that
75does a jump to another buffer while in Visual mode, the highlighting stops
76and no text is affected.  Also when you hit "v" in characterwise Visual mode,
77"CTRL-V" in blockwise Visual mode or "V" in linewise Visual mode.  If you hit
78CTRL-Z the highlighting stops and the editor is suspended or a new shell is
79started |CTRL-Z|.
80
81	      new mode after typing:		*v_v* *v_CTRL-V* *v_V*
82old mode	     "v"	      "CTRL-V"		     "V"	~
83
84Normal		    Visual	   blockwise Visual	  linewise Visual
85Visual		    Normal	   blockwise Visual	  linewise Visual
86blockwise Visual    Visual	   Normal		  linewise Visual
87linewise Visual     Visual	   blockwise Visual	  Normal
88
89						*gv* *v_gv* *reselect-Visual*
90gv			Start Visual mode with the same area as the previous
91			area and the same mode.
92			In Visual mode the current and the previous Visual
93			area are exchanged.
94			After using "p" or "P" in Visual mode the text that
95			was put will be selected.
96
97							*<LeftMouse>*
98<LeftMouse>		Set the current cursor position.  If Visual mode is
99			active it is stopped.  Only when 'mouse' option is
100			contains 'n' or 'a'.  If the position is within 'so'
101			lines from the last line on the screen the text is
102			scrolled up.  If the position is within 'so' lines from
103			the first line on the screen the text is scrolled
104			down.
105
106							*<RightMouse>*
107<RightMouse>		Start Visual mode if it is not active.  The text from
108			the cursor position to the position of the click is
109			highlighted.  If Visual mode was already active move
110			the start or end of the highlighted text, which ever
111			is closest, to the position of the click.  Only when
112			'mouse' option contains 'n' or 'a'.
113
114			Note: when 'mousemodel' is set to "popup",
115			<S-LeftMouse> has to be used instead of <RightMouse>.
116
117							*<LeftRelease>*
118<LeftRelease>		This works like a <LeftMouse>, if it is not at
119			the same position as <LeftMouse>.  In an older version
120			of xterm you won't see the selected area until the
121			button is released, unless there is access to the
122			display where the xterm is running (via the DISPLAY
123			environment variable or the -display argument).  Only
124			when 'mouse' option contains 'n' or 'a'.
125
126If Visual mode is not active and the "v", "V" or CTRL-V is preceded with a
127count, the size of the previously highlighted area is used for a start.  You
128can then move the end of the highlighted area and give an operator.  The type
129of the old area is used (character, line or blockwise).
130- Linewise Visual mode: The number of lines is multiplied with the count.
131- Blockwise Visual mode: The number of lines and columns is multiplied with
132  the count.
133- Normal Visual mode within one line: The number of characters is multiplied
134  with the count.
135- Normal Visual mode with several lines: The number of lines is multiplied
136  with the count, in the last line the same number of characters is used as
137  in the last line in the previously highlighted area.
138The start of the text is the Cursor position.  If the "$" command was used as
139one of the last commands to extend the highlighted text, the area will be
140extended to the rightmost column of the longest line.
141
142If you want to highlight exactly the same area as the last time, you can use
143"gv" |gv| |v_gv|.
144
145							*v_<Esc>*
146<Esc>			In Visual mode: Stop Visual mode.
147
148							*v_CTRL-C*
149CTRL-C			In Visual mode: Stop Visual mode.  When insert mode is
150			pending (the mode message shows
151			"-- (insert) VISUAL --"), it is also stopped.
152
153==============================================================================
1543. Changing the Visual area				*visual-change*
155
156							*v_o*
157o			Go to Other end of highlighted text: The current
158			cursor position becomes the start of the highlighted
159			text and the cursor is moved to the other end of the
160			highlighted text.  The highlighted area remains the
161			same.
162
163							*v_O*
164O			Go to Other end of highlighted text.  This is like
165			"o", but in Visual block mode the cursor moves to the
166			other corner in the same line.  When the corner is at
167			a character that occupies more than one position on
168			the screen (e.g., a <Tab>), the highlighted text may
169			change.
170
171							*v_$*
172When the "$" command is used with blockwise Visual mode, the right end of the
173highlighted text will be determined by the longest highlighted line.  This
174stops when a motion command is used that does not move straight up or down.
175
176For moving the end of the block many commands can be used, but you cannot
177use Ex commands, commands that make changes or abandon the file.  Commands
178(starting with) ".", "&", CTRL-^, "Z", CTRL-], CTRL-T, CTRL-R, CTRL-I
179and CTRL-O cause a beep and Visual mode continues.
180
181When switching to another window on the same buffer, the cursor position in
182that window is adjusted, so that the same Visual area is still selected.  This
183is especially useful to view the start of the Visual area in one window, and
184the end in another.  You can then use <RightMouse> (or <S-LeftMouse> when
185'mousemodel' is "popup") to drag either end of the Visual area.
186
187==============================================================================
1884. Operating on the Visual area				*visual-operators*
189
190The operators that can be used are:
191	~	switch case					|v_~|
192	d	delete						|v_d|
193	c	change (4)					|v_c|
194	y	yank						|v_y|
195	>	shift right (4)					|v_>|
196	<	shift left (4)					|v_<|
197	!	filter through external command (1)		|v_!|
198	=	filter through 'equalprg' option command (1)	|v_=|
199	gq	format lines to 'textwidth' length (1)		|v_gq|
200
201The objects that can be used are:
202	aw	a word (with white space)			|v_aw|
203	iw	inner word					|v_iw|
204	aW	a WORD (with white space)			|v_aW|
205	iW	inner WORD					|v_iW|
206	as	a sentence (with white space)			|v_as|
207	is	inner sentence					|v_is|
208	ap	a paragraph (with white space)			|v_ap|
209	ip	inner paragraph					|v_ip|
210	ab	a () block (with parenthesis)			|v_ab|
211	ib	inner () block					|v_ib|
212	aB	a {} block (with braces)			|v_aB|
213	iB	inner {} block					|v_iB|
214	at	a <tag> </tag> block (with tags)		|v_at|
215	it	inner <tag> </tag> block			|v_it|
216	a<	a <> block (with <>)				|v_a<|
217	i<	inner <> block					|v_i<|
218	a[	a [] block (with [])				|v_a[|
219	i[	inner [] block					|v_i[|
220	a"	a double quoted string (with quotes)		|v_aquote|
221	i"	inner double quoted string			|v_iquote|
222	a'	a single quoted string (with quotes)		|v_a'|
223	i'	inner simple quoted string			|v_i'|
224	a`	a string in backticks (with backticks)		|v_a`|
225	i`	inner string in backticks			|v_i`|
226
227Additionally the following commands can be used:
228	:	start Ex command for highlighted lines (1)	|v_:|
229	r	change (4)					|v_r|
230	s	change						|v_s|
231	C	change (2)(4)					|v_C|
232	S	change (2)					|v_S|
233	R	change (2)					|v_R|
234	x	delete						|v_x|
235	D	delete (3)					|v_D|
236	X	delete (2)					|v_X|
237	Y	yank (2)					|v_Y|
238	p	put						|v_p|
239	J	join (1)					|v_J|
240	U	make uppercase					|v_U|
241	u	make lowercase					|v_u|
242	^]	find tag					|v_CTRL-]|
243	I	block insert					|v_b_I|
244	A	block append					|v_b_A|
245
246(1): Always whole lines, see |:visual_example|.
247(2): Whole lines when not using CTRL-V.
248(3): Whole lines when not using CTRL-V, delete until the end of the line when
249     using CTRL-V.
250(4): When using CTRL-V operates on the block only.
251
252Note that the ":vmap" command can be used to specifically map keys in Visual
253mode.  For example, if you would like the "/" command not to extend the Visual
254area, but instead take the highlighted text and search for that: >
255	:vmap / y/<C-R>"<CR>
256(In the <> notation |<>|, when typing it you should type it literally; you
257need to remove the 'B' and '<' flags from 'cpoptions'.)
258
259If you want to give a register name using the """ command, do this just before
260typing the operator character: "v{move-around}"xd".
261
262If you want to give a count to the command, do this just before typing the
263operator character: "v{move-around}3>" (move lines 3 indents to the right).
264
265							*{move-around}*
266The {move-around} is any sequence of movement commands.  Note the difference
267with {motion}, which is only ONE movement command.
268
269Another way to operate on the Visual area is using the |/\%V| item in a
270pattern.  For example, to replace all '(' in the Visual area with '#': >
271
272	:%s/\%V(/X/g
273
274==============================================================================
2755. Blockwise operators					*blockwise-operators*
276
277{not available when compiled without the |+visualextra| feature}
278
279Reminder: Use 'virtualedit' to be able to select blocks that start or end
280after the end of a line or halfway a tab.
281
282Visual-block Insert						*v_b_I*
283With a blockwise selection, I{string}<ESC> will insert {string} at the start
284of block on every line of the block, provided that the line extends into the
285block.  Thus lines that are short will remain unmodified.  TABs are split to
286retain visual columns.
287See |v_b_I_example|.
288
289Visual-block Append						*v_b_A*
290With a blockwise selection, A{string}<ESC> will append {string} to the end of
291block on every line of the block.  There is some differing behavior where the
292block RHS is not straight, due to different line lengths:
293
2941. Block was created with <C-v>$
295    In this case the string is appended to the end of each line.
2962. Block was created with <C-v>{move-around}
297    In this case the string is appended to the end of the block on each line,
298    and whitespace is inserted to pad to the end-of-block column.
299See |v_b_A_example|.
300Note: "I" and "A" behave differently for lines that don't extend into the
301selected block.  This was done intentionally, so that you can do it the way
302you want.
303
304Visual-block change						*v_b_c*
305All selected text in the block will be replaced by the same text string.  When
306using "c" the selected text is deleted and Insert mode started.  You can then
307enter text (without a line break).  When you hit <Esc>, the same string is
308inserted in all previously selected lines.
309
310Visual-block Change						*v_b_C*
311Like using "c", but the selection is extended until the end of the line for
312all lines.
313
314								*v_b_<*
315Visual-block Shift						*v_b_>*
316The block is shifted by 'shiftwidth'.  The RHS of the block is irrelevant.  The
317LHS of the block determines the point from which to apply a right shift, and
318padding includes TABs optimally according to 'ts' and 'et'.  The LHS of the
319block determines the point upto which to shift left.
320See |v_b_>_example|.
321See |v_b_<_example|.
322
323Visual-block Replace						*v_b_r*
324Every screen char in the highlighted region is replaced with the same char, ie
325TABs are split and the virtual whitespace is replaced, maintaining screen
326layout.
327See |v_b_r_example|.
328
329
330==============================================================================
3316. Repeating						*visual-repeat*
332
333When repeating a Visual mode operator, the operator will be applied to the
334same amount of text as the last time:
335- Linewise Visual mode: The same number of lines.
336- Blockwise Visual mode: The same number of lines and columns.
337- Normal Visual mode within one line: The same number of characters.
338- Normal Visual mode with several lines: The same number of lines, in the
339  last line the same number of characters as in the last line the last time.
340The start of the text is the Cursor position.  If the "$" command was used as
341one of the last commands to extend the highlighted text, the repeating will
342be applied up to the rightmost column of the longest line.
343
344
345==============================================================================
3467. Examples						*visual-examples*
347
348							*:visual_example*
349Currently the ":" command works on whole lines only.  When you select part of
350a line, doing something like ":!date" will replace the whole line.  If you
351want only part of the line to be replaced you will have to make a mapping for
352it.  In a future release ":" may work on partial lines.
353
354Here is an example, to replace the selected text with the output of "date": >
355	:vmap _a <Esc>`>a<CR><Esc>`<i<CR><Esc>!!date<CR>kJJ
356
357(In the <> notation |<>|, when typing it you should type it literally; you
358need to remove the 'B' and '<' flags from 'cpoptions')
359
360What this does is:
361<Esc>		stop Visual mode
362`>		go to the end of the Visual area
363a<CR><Esc>	break the line after the Visual area
364`<		jump to the start of the Visual area
365i<CR><Esc>	break the line before the Visual area
366!!date<CR>	filter the Visual text through date
367kJJ		Join the lines back together
368
369							*visual-search*
370Here is an idea for a mapping that makes it possible to do a search for the
371selected text: >
372	:vmap X y/<C-R>"<CR>
373
374(In the <> notation |<>|, when typing it you should type it literally; you
375need to remove the 'B' and '<' flags from 'cpoptions')
376
377Note that special characters (like '.' and '*') will cause problems.
378
379Visual-block Examples					*blockwise-examples*
380With the following text, I will indicate the commands to produce the block and
381the results below.  In all cases, the cursor begins on the 'a' in the first
382line of the test text.
383The following modeline settings are assumed ":ts=8:sw=4:".
384
385It will be helpful to
386:set hls
387/<TAB>
388where <TAB> is a real TAB.  This helps visualise the operations.
389
390The test text is:
391

432==============================================================================
4338. Select mode						*Select* *Select-mode*
434
435Select mode looks like Visual mode, but the commands accepted are quite
436different.  This resembles the selection mode in Microsoft Windows.
437When the 'showmode' option is set, "-- SELECT --" is shown in the last line.
438
439Entering Select mode:
440- Using the mouse to select an area, and 'selectmode' contains "mouse".
441  'mouse' must also contain a flag for the current mode.
442- Using a non-printable movement command, with the Shift key pressed, and
443  'selectmode' contains "key".  For example: <S-Left> and <S-End>.  'keymodel'
444  must also contain "startsel".
445- Using "v", "V" or CTRL-V command, and 'selectmode' contains "cmd".
446- Using "gh", "gH" or "g_CTRL-H" command in Normal mode.
447- From Visual mode, press CTRL-G.			*v_CTRL-G*
448
449Commands in Select mode:
450- Printable characters, <NL> and <CR> cause the selection to be deleted, and
451  Vim enters Insert mode.  The typed character is inserted.
452- Non-printable movement commands, with the Shift key pressed, extend the
453  selection.  'keymodel' must include "startsel".
454- Non-printable movement commands, with the Shift key NOT pressed, stop Select
455  mode.  'keymodel' must include "stopsel".
456- ESC stops Select mode.
457- CTRL-O switches to Visual mode for the duration of one command. *v_CTRL-O*
458- CTRL-G switches to Visual mode.
459
460Otherwise, typed characters are handled as in Visual mode.
461
462When using an operator in Select mode, and the selection is linewise, the
463selected lines are operated upon, but like in characterwise selection.  For
464example, when a whole line is deleted, it can later be pasted halfway a line.
465
466
467Mappings and menus in Select mode.			*Select-mode-mapping*
468
469When mappings and menus are defined with the |:vmap| or |:vmenu| command they
470work both in Visual mode and in Select mode.  When these are used in Select
471mode Vim automatically switches to Visual mode, so that the same behavior as
472in Visual mode is effective.  If you don't want this use |:xmap| or |:smap|.
473
474Users will expect printable characters to replace the selected area.
475Therefore avoid mapping printable characters in Select mode.  Or use
476|:sunmap|  after |:map| and |:vmap| to remove it for Select mode.
477
478After the mapping or menu finishes, the selection is enabled again and Select
479mode entered, unless the selected area was deleted, another buffer became
480the current one or the window layout was changed.
481
482When a character was typed that causes the selection to be deleted and Insert
483mode started, Insert mode mappings are applied to this character.  This may
484cause some confusion, because it means Insert mode mappings apply to a
485character typed in Select mode.  Language mappings apply as well.
486
487							*gV* *v_gV*
488gV			Avoid the automatic reselection of the Visual area
489			after a Select mode mapping or menu has finished.
490			Put this just before the end of the mapping or menu.
491			At least it should be after any operations on the
492			selection.
493
494							*gh*
495gh			Start Select mode, characterwise.  This is like "v",
496			but starts Select mode instead of Visual mode.
497			Mnemonic: "get highlighted".
498
499							*gH*
500gH			Start Select mode, linewise.  This is like "V",
501			but starts Select mode instead of Visual mode.
502			Mnemonic: "get Highlighted".
