Allow CTRL-_ in Insert and Command-line mode. This is default off, to avoid that users that accidentally type CTRL-_ instead of SHIFT-_ get into reverse Insert mode, and don't know how to get out. See 'revins'. NOTE: This option is reset when 'compatible' is set. | |
Only effective when 'encoding' is "utf-8" or another Unicode encoding. Tells Vim what to do with characters with East Asian Width Class Ambiguous (such as Euro, Registered Sign, Copyright Sign, Greek letters, Cyrillic letters). | |
This option can be set to start editing Arabic text. Setting this option will:
| |
When on and 'termbidi' is off, the required visual character
corrections that need to take place for displaying the Arabic language
take effect. Shaping, in essence, gets enabled; the term is a broad
one which encompasses:
a) the changing/morphing of characters based on their location
within a word (initial, medial, final and stand-alone).
b) the enabling of the ability to compose characters
c) the enabling of the required combining of some characters
When disabled the display shows each character's true stand-alone
form.
Arabic is a complex language which requires other settings, for
further details see | |
When on, Vim will change the current working directory whenever you open a file, switch buffers, delete a buffer or open/close a window. It will change to the directory containing the file which was opened or selected. When a buffer has no name it also has no directory, thus the current directory won't change when navigating to it. Note: When this option is on some plugins may not work. | |

When a file has been detected to have been changed outside of Vim and
it has not been changed inside of Vim, automatically read it again.

Like 'autowrite', but also used for commands ":edit", ":enew", ":quit", ":qall", ":exit", ":xit", ":recover" and closing the Vim window. Setting this option also implies that Vim behaves like 'autowrite' has been set. | |
When set to "dark", Vim will try to use colors that look good on a
dark background. When set to "light", Vim will try to use colors that
look good on a light background. Any other value is illegal.
Vim tries to set the default value according to the terminal used.
This will not always be correct.
Setting this option does not change the background color, it tells Vim
what the background color looks like. For changing the background
color, see | |

Make a backup before overwriting a file. Leave it around after the
file has been successfully written. If you do not want to keep the
backup file, but you do want a backup while the file is being
written, reset this option and set the 'writebackup' option (this is
the default). If you do not want a backup file at all reset both
options (use this if your file system is almost full). See the

This option lets you choose which characters might cause a line break if 'linebreak' is on. Only works for ASCII and also for 8-bit characters when 'encoding' is an 8-bit encoding. | |
Every wrapped line will continue visually indented (same amount of space as the beginning of that line), thus preserving horizontal blocks of text. NOTE: This option is reset when 'compatible' is set. | |
Settings for 'breakindent'. It can consist of the following optional items and must be separated by a comma: min:{n} Minimum text width that will be kept after applying 'breakindent', even if the resulting text should normally be narrower. This prevents text indented almost to the right window border occupying lot of vertical space when broken. (default: 20) shift:{n} After applying 'breakindent', the wrapped line's beginning will be shifted by the given number of characters. It permits dynamic French paragraph indentation (negative) or emphasizing the line continuation (positive). (default: 0) sbr Display the 'showbreak' value before applying the additional indent. (default: off) list:{n} Adds an additional indent for lines that match a numbered or bulleted list (using the 'formatlistpat' setting). list:-1 Uses the length of a match with 'formatlistpat' for indentation. (default: 0) column:{n} Indent at column {n}. Will overrule the other sub-options. Note: an additional indent may be added for the 'showbreak' setting. (default: off) | |
Which directory to use for the file browser: last Use same directory as with last file browser, where a file was opened or saved. buffer Use the directory of the related buffer. current Use the current directory. {path} Use the specified directory | |
This option specifies what happens when a buffer is no longer
displayed in a window:
| |
When this option is set, the buffer shows up in the buffer list. If it is reset it is not used for ":bnext", "ls", the Buffers menu, etc. This option is reset by Vim for buffers that are only used to remember a file name or marks. Vim sets it when starting to edit a buffer. But not when moving to a buffer with ":buffer". | |
The value of this option specifies the type of a buffer:
| |
Specifies details about changing the case of letters. It may contain these words, separated by a comma: internal Use internal case mapping functions, the current locale does not change the case mapping. This only matters when 'encoding' is a Unicode encoding, "latin1" or "iso-8859-15". When "internal" is omitted, the towupper() and towlower() system library functions are used when available. keepascii For the ASCII characters (0x00 to 0x7f) use the US case mapping, the current locale is not effective. This probably only matters for Turkish. | |

An expression that is used for character encoding conversion. It is
evaluated when a file that is to be read or has been written has a
different encoding from what is desired.
'charconvert' is not used when the internal iconv() function is
supported and is able to do the conversion. Using iconv() is
preferred, because it is much faster.
'charconvert' is not used when reading stdin | |
Enables automatic C program indenting. See 'cinkeys' to set the keys
that trigger reindenting in insert mode and 'cinoptions' to set your
preferred indent style.
If 'indentexpr' is not empty, it overrules 'cindent'.
If 'lisp' is not on and both 'indentexpr' and 'equalprg' are empty,
the "=" operator indents using this algorithm rather than calling an
external program.
See | |
A list of keys that, when typed in Insert mode, cause reindenting of
the current line. Only used if 'cindent' is on and 'indentexpr' is
empty.
For the format of this option see | |
The 'cinoptions' affect the way 'cindent' reindents lines in a C
program. See | |
Keywords that are interpreted as a C++ scope declaration by | |
These keywords start an extra indent in the next line when 'smartindent' or 'cindent' is set. For 'cindent' this is only done at an appropriate place (inside {}). Note that 'ignorecase' isn't used for 'cinwords'. If case doesn't matter, include the keyword both the uppercase and lowercase: "if,If,IF". | |
This option is a list of comma-separated names. Note: if one of the items is "exclude:", then you can't add an item after that. Therefore do not append an item with += but use ^= to prepend, e.g.: | |

When on, all the windows are automatically made the same size after splitting or closing a window. This also happens the moment the option is switched on. When off, splitting a window will reduce the size of the current window and leave the other windows the same. When closing a window the extra lines are given to the window next to it (depending on 'splitbelow' and 'splitright'). When mixing vertically and horizontally split windows, a minimal size is computed and some windows may be larger if there is room. The 'eadirection' option tells in which direction the size is affected. Changing the height and width of a window can be avoided by setting 'winfixheight' and 'winfixwidth', respectively. If a window size is specified when creating a new window sizes are currently not equalized (it's complicated, but may be implemented in the future). | |
External program to use for "=" command. When this option is empty
the internal formatting functions are used; either 'lisp', 'cindent'
or 'indentexpr'. When Vim was compiled without internal formatting,
the "indent" program is used.

v exrc | Enables the reading of .vimrc, .exrc and .gvimrc in the current directory. |
Sets the character encoding for the file of this buffer. | |
This is a list of character encodings considered when starting to edit
an existing file. When a file is read, Vim tries to use the first
mentioned character encoding. If an error is detected, the next one
in the list is tried. When an encoding is found that works,
'fileencoding' is set to it. If all fail, 'fileencoding' is set to
an empty string, which means the value of 'encoding' is used.
WARNING: Conversion can cause loss of information! When
'encoding' is "utf-8" (or one of the other Unicode variants)
conversion is most likely done in a way that the reverse
conversion results in the same text. When 'encoding' is not
"utf-8" some non-ASCII characters may be lost! You can use

When this option is set, the FileType autocommand event is triggered.
All autocommands that match with the value of this option will be
executed. Thus the value of 'filetype' is used in place of the file
name.
Otherwise this option does not always reflect the current file type.
This option is normally set when the file type is detected. To enable
this use the ":filetype on" command. | |
Characters to fill the statuslines, vertical separators and special lines in the window. It is a comma-separated list of items. Each item has a name, a colon and the value of that item: | |
When writing a file and this option is on, | |
When set to "all", a fold is closed when the cursor isn't in it and its level is higher than 'foldlevel'. Useful if you want folds to automatically close when moving out of them. | |
When non-zero, a column with the specified width is shown at the side
of the window which indicates open and closed folds. The maximum
value is 12.
See | |
When off, all folds are open. This option can be used to quickly
switch between showing all text unfolded and viewing the text with
folds (including manually opened or closed folds). It can be toggled
with the | |
The expression used for when 'foldmethod' is "expr". It is evaluated
for each line to obtain its fold level. The context is set to the
script where 'foldexpr' was set, script-local items can be accessed.
See | |
Used only when 'foldmethod' is "indent". Lines starting with
characters in 'foldignore' will get their fold level from surrounding
lines. White space is skipped before checking for this character.
The default "#" works well for C programs. See | |
Sets the fold level: Folds with a higher level will be closed.
Setting this option to zero will close all folds. Higher numbers will
close fewer folds.
This option is set by commands like | |
Sets 'foldlevel' when starting to edit another buffer in a window.
Useful to always start editing with all folds closed (value zero),
some folds closed (one) or no folds closed (99).
This is done before reading any modeline, thus a setting in a modeline
overrules this option. Starting to edit a file for | |
The start and end marker used when 'foldmethod' is "marker". There
must be one comma, which separates the start and end marker. The
marker is a literal string (a regular expression would be too slow).
See | |
The kind of folding used for the current window. Possible values:
| |
Sets the number of screen lines above which a fold can be displayed closed. Also for manually closed folds. With the default value of one a fold can only be closed if it takes up two or more screen lines. Set to zero to be able to close folds of just one screen line. Note that this only has an effect on what is displayed. After using "zc" to close a fold, which is displayed open because it's smaller than 'foldminlines', a following "zc" may close a containing fold. | |
Sets the maximum nesting of folds for the "indent" and "syntax" methods. This avoids that too many folds will be created. Using more than 20 doesn't work, because the internal limit is 20. | |
Specifies for which type of commands folds will be opened, if the
command moves the cursor into a closed fold. It is a comma-separated
list of items.
NOTE: When the command is part of a mapping this option is not used.

When on, the library function fsync() will be called after writing a
file. This will flush a file to disk, ensuring that it is safely
written even on filesystems which do metadata-only journaling. This
will force the harddrive to spin up on Linux systems running in laptop
mode, so it may be undesirable in some situations. Be warned that
turning this off increases the chances of data loss after a crash. On
systems without an fsync() implementation, this variable is always
off.
Also see 'swapsync' for controlling fsync() on swap files.
'fsync' also applies to | |
When on, the ":substitute" flag 'g' is default on. This means that

This option tells Vim what the cursor should look like in different modes. It fully works in the GUI. In a Win32 console, only the height of the cursor can be changed. This can be done by specifying a block cursor, or a percentage for a vertical or horizontal cursor. For a console the 't_SI', 't_SR', and 't_EI' escape sequences are used. | |
This is a list of fonts which will be used for the GUI version of Vim.
In its simplest form the value is just one font name.

Minimal initial height of the help window when it is opened with the ":help" command. The initial height of the help window is half of the current window, or (when the 'ea' option is on) the same as other windows. When the height is less than 'helpheight', the height is set to 'helpheight'. Set to zero to disable. | |
Comma-separated list of languages. Vim will use the first language for which the desired help can be found. The English help will always be used as a last resort. You can add "en" to prefer English over another language, but that will only find tags that exist in that language and not in the English help. Example: | |

each of these histories (see | |
When there is a previous search pattern, highlight all its matches.
The type of highlighting used can be set with the 'l' occasion in the
'highlight' option. This uses the "Search" highlight group by
default. Note that only the matching text is highlighted, any offsets
are not applied. If the "CurSearch" highlight group is set then the
current match is highlighted with that.

This option allows switching your keyboard into a special language
mode. When you are typing text in Insert mode the characters are
inserted directly. When in Normal mode the 'langmap' option takes
care of translating these special characters to the original meaning
of the key. This means you don't have to change the keyboard mode to
be able to execute Normal mode commands.
This is the opposite of the 'keymap' option, where characters are
mapped in Insert mode.
Also consider setting 'langremap' to off, to prevent 'langmap' from
applying to characters resulting from a mapping.
This option cannot be set from a | |

When off, setting 'langmap' does not apply to characters resulting from a mapping. This basically means, if you noticed that setting 'langmap' disables some of your mappings, try resetting this option. This option defaults to on for backwards compatibility. Set it off if that works for you to avoid mappings to break. | |
The value of this option influences when the last window will have a
status line:
0: never
1: only if there are at least two windows
2: always
The screen looks nicer with a status line if you have several
windows, but it takes another screen line. | |
When this option is set, the screen will not be redrawn while
executing macros, registers and other commands that have not been

Number of pixel lines inserted between characters. Useful if the font uses the full character cell height, making lines touch each other. When non-zero there is room for underlining. With some fonts there can be too much room between lines (to have space for ascents and descents). Then it makes sense to set 'linespace' to a negative value. This may cause display problems though! | |

The window that the mouse pointer is on is automatically activated. When changing the window layout or window focus in another way, the mouse pointer is moved to the window with keyboard focus. Off is the default because it makes using the pull down menus a little goofy, as a pointer transit may activate a window unintentionally. MS-Windows: Also see 'scrollfocus' for what window is scrolled when using the mouse scroll wheel. | |
When on, the mouse pointer is hidden when characters are typed. The mouse pointer is restored when the mouse is moved. | |
Sets the model to use for the mouse. The name mostly specifies what the right mouse button is used for: extend Right mouse button extends a selection. This works like in an xterm. popup Right mouse button pops up a menu. The shifted left mouse button extends a selection. This works like with Microsoft Windows. popup_setpos Like "popup", but the cursor will be moved to the position where the mouse was clicked, and thus the selected operation will act upon the clicked object. If clicking inside a selection, that selection will be acted upon, i.e. no cursor move. This implies of course, that right clicking outside a selection will end Visual mode.

This option tells Vim what the mouse pointer should look like in different modes. The option is a comma-separated list of parts, much like used for 'guicursor'. Each part consist of a mode/location-list and an argument-list: mode-list:shape,mode-list:shape,..

Print the line number in front of each line. When the 'n' option is
excluded from 'cpoptions' a wrapped line will not use the column of
line numbers (this is the default when 'compatible' isn't set).
The 'numberwidth' option can be used to set the room used for the line
number.
When a long, wrapped line doesn't start with the first character, '-'
characters are put before the number.
For highlighting see | |
Minimal number of columns to use for the line number. Only relevant when the 'number' or 'relativenumber' option is set or printing lines with a line number. Since one space is always between the number and the text, there is one less character for the number itself. The value is the minimum width. A bigger width is used when needed to fit the highest line number in the buffer respectively the number of rows in the window, depending on whether 'number' or 'relativenumber' is set. Thus with the Vim default of 4 there is room for a line number up to 999. When the buffer has 1000 lines five columns will be used. The minimum value is 1, the maximum value is 20. NOTE: This option is set to the Vi default value when 'compatible' is set and to the Vim default value when 'compatible' is reset. | |

When non-empty the oldest version of a file is kept. This can be used
to keep the original version of a file if you are changing files in a
source distribution. Only the first time that a file is written a
copy of the original file will be kept. The name of the copy is the
name of the original file with the string in the 'patchmode' option
appended. This option should start with a dot. Use a string like
".orig" or ".org". 'backupdir' must not be empty for this to work
(Detail: The backup file is renamed to the patchmode file after the
new file has been successfully written, that's why it must be possible
to write a backup file). If there was no file to be backed up, an
empty file is created.
When the 'backupskip' pattern matches, a patchmode file is not made.
Using 'patchmode' for compressed files appends the extension at the
end (e.g., "file.gz.orig"), thus the resulting name isn't always
recognized as a compressed file.

When on, display orientation becomes right-to-left, i.e., characters
that are stored in the file appear from the right to the left.
Using this option, it is possible to edit files for languages that
are written from the right to the left such as Hebrew and Arabic.
This option is per window, so it is possible to edit mixed files
simultaneously, or to view the same file in both ways (this is
useful whenever you have a mixed text file with both right-to-left
and left-to-right strings so that both sets are displayed properly
in different windows). Also see | |
Each word in this option enables the command line editing to work in right-to-left mode for a group of commands: | |

45% relative position in the file
If 'rulerformat' is set, it will determine the contents of the ruler.
Each window has its own ruler. If a window has a status line, the
ruler is shown there. Otherwise it is shown in the last line of the
screen. If the statusline is given by 'statusline' (i.e. not empty),
this option takes precedence over 'ruler' and 'rulerformat'.
If the number of characters displayed is different from the number of
bytes in the text (e.g., for a TAB or a multibyte character), both
the text column (byte number) and the screen column are shown,
separated with a dash.
For an empty line "0-1" is shown.
For an empty buffer the line number will also be zero: "0,0-1".
This option is reset when 'paste' is set and restored when 'paste' is
reset.
If you don't want to see the ruler all the time but want to know where
you are, use "g CTRL-G" | |
When this option is not empty, it determines the content of the ruler string, as displayed for the 'ruler' option. The format of this option is like that of 'statusline'. This option cannot be set in a modeline when 'modelineexpr' is off. | |

Minimal number of lines to scroll when the cursor gets off the screen (e.g., with "j"). Not used for scroll commands (e.g., CTRL-E, CTRL-D). Useful if your terminal scrolls very slowly. When set to a negative number from -1 to -100 this is used as the percentage of the window height. Thus -50 scrolls half the window height. NOTE: This option is set to 1 when 'compatible' is set. | |
Minimal number of screen lines to keep above and below the cursor. This will make some context visible around where you are working.

This is a comma-separated list of words that specifies how
'scrollbind' windows should behave. 'sbo' stands for ScrollBind
Options.
The following words are available:
ver Bind vertical scrolling for 'scrollbind' windows
hor Bind horizontal scrolling for 'scrollbind' windows
jump Applies to the offset between two windows for vertical
scrolling. This offset is the difference in the first
displayed line of the bound windows. When moving
around in a window, another 'scrollbind' window may
reach a position before the start or after the end of
the buffer. The offset is not changed though, when
moving back the 'scrollbind' window will try to scroll
to the desired position when possible.
When now making that window the current one, two
things can be done with the relative offset:
1. When "jump" is not included, the relative offset is
adjusted for the scroll position in the new current
window. When going back to the other window, the
new relative offset will be used.
2. When "jump" is included, the other windows are
scrolled to keep the same relative offset. When
going back to the other window, it still uses the
same relative offset.

This option defines the behavior of the selection. It is only used in Visual and Select mode. Possible values: value past line inclusive old no yes inclusive yes yes exclusive yes no "past line" means that the cursor is allowed to be positioned one character past the line. "inclusive" means that the last character of the selection is included in an operation. For example, when "x" is used to delete the selection. When "old" is used and 'virtualedit' allows the cursor to move past the end of line the line break still isn't included. Note that when "exclusive" is used and selecting from the end backwards, you cannot include the last character of a line, when starting in Normal mode and 'virtualedit' empty. | |

When set, a forward slash is used when expanding file names. This is useful when a Unix-like shell is used instead of cmd.exe, pwsh.exe, or powershell.exe. Backward slashes can still be typed, but they are changed to forward slashes by Vim. Note that setting or resetting this option has no effect for some existing file names, thus this option needs to be set before opening any file for best results. This might change in the future.

Maximum number of changes that can be undone. Since undo information is kept in memory, higher numbers will cause more memory to be used. Nevertheless, a single change can already use a large amount of memory. Set to 0 for Vi compatibility: One level of undo and "u" undoes itself: | |
Save the whole buffer for undo when reloading it. This applies to the

When bigger than zero, Vim will give messages about what it is doing. Currently, these messages are given:
| |
When not empty all messages are written in a file with this name.
When the file exists messages are appended.
Writing to the file ends when Vim exits or when 'verbosefile' is made
empty. Writes are buffered, thus may not show up for some time.
Setting 'verbosefile' to a new value is like making it empty first.

Minimal number of lines for the current window. This is not a hard

cost of the height of other windows.
Set 'winheight' to a small number for normal editing.
Set it to 999 to make the current window fill most of the screen.
Other windows will be only 'winminheight' high. This has the drawback

The minimal height of a window, when it's not the current window. This is a hard minimum, windows will never become smaller. When set to zero, windows may be "squashed" to zero lines (i.e. just a status bar) if necessary. They will return to at least one line when they become active (since the cursor has to have somewhere to go.) Use 'winheight' to set the minimal height of the current window. This option is only checked when making a window smaller. Don't use a large number, it will cause errors when opening more than a few windows. A value of 0 to 3 is reasonable. | |
The minimal width of a window, when it's not the current window. This is a hard minimum, windows will never become smaller. When set to zero, windows may be "squashed" to zero columns (i.e. just a vertical separator) if necessary. They will return to at least one line when they become active (since the cursor has to have somewhere to go.) Use 'winwidth' to set the minimal width of the current window. This option is only checked when making a window smaller. Don't use a large number, it will cause errors when opening more than a few windows. A value of 0 to 12 is reasonable. | |
Minimal number of columns for the current window. This is not a hard minimum, Vim will use fewer columns if there is not enough room. If the current window is smaller, its size is increased, at the cost of the width of other windows. Set it to 999 to make the current window always fill the screen. Set it to a small number for normal editing. The width is not adjusted after one of the commands to change the width of the current window. 'winwidth' applies to the current window. Use 'winminwidth' to set the minimal width for other windows. | |
v wrap | This option changes how text is displayed. It doesn't change the text in the buffer, see 'textwidth' for that. When on, lines longer than the width of the window will wrap and displaying continues on the next line. When off lines will not wrap and only part of long lines will be displayed. When the cursor is moved to a part that is not shown, the screen will scroll horizontally. The line will be broken in the middle of a word if necessary. See 'linebreak' to get the break at a word boundary. To make scrolling horizontally a bit more useful, try this: |

Make a backup before overwriting a file. The backup is removed after
the file was successfully written, unless the 'backup' option is
also on.
WARNING: Switching this option off means that when Vim fails to write
your buffer correctly and then, for whatever reason, Vim exits, you
lose both the original file and what you were writing. Only reset
this option if your file system is almost full and it makes the write
fail (and make sure not to exit Vim until the write was successful).
