ZLE BUILTINS

bindkey [ options ] -l [ -L ] [ keymap ... ]

bindkey [ options ] -d

bindkey [ options ] -D keymap ...

bindkey [ options ] -A old-keymap new-keymap

bindkey [ options ] -N new-keymap [ old-keymap ]

bindkey [ options ] -m

bindkey [ options ] -r in-string ...

bindkey [ options ] -s in-string out-string ...

bindkey [ options ] in-string command ...

bindkey [ options ] [ in-string ]

bindkey's options can be divided into three categories: keymap selection for the current command, operation selection, and others. The keymap selection options are:

bindkey -N mymap emacs
bindkey -A mymap main

bindkey -rpM viins '^['

vared [ -Aacghe ] [ -p prompt ] [ -r rprompt ]

[ -M main-keymap ] [ -m vicmd-keymap ]

[ -i init-widget ] [ -f finish-widget ]

[ -t tty ] name

The value of the parameter name is loaded into the edit buffer, and the line editor is invoked. When the editor exits, name is set to the string value returned by the editor. When the -c flag is given, the parameter is created if it doesn't already exist. The -a flag may be given with -c to create an array parameter, or the -A flag to create an associative array. If the type of an existing parameter does not match the type to be created, the parameter is unset and recreated. The -g flag may be given to suppress warnings from the WARN_CREATE_GLOBAL and WARN_NESTED_VAR options.

WIDGETS

USER-DEFINED WIDGETS

widget-function() {
  # $WIDGET here refers to the special variable
  # that is local inside widget-function
  () {
     # This anonymous nested function allows WIDGET
     # to be used as a local variable.  The -h
     # removes the special status of the variable.
     local -h WIDGET
  }
}

BUFFER (scalar)

The entire contents of the edit buffer. If it is written to, the cursor remains at the same offset, unless that would put it outside the buffer.

BUFFERLINES (integer)

The number of screen lines needed for the edit buffer currently displayed on screen (i.e. without any changes to the preceding parameters done after the last redisplay); read-only.

CONTEXT (scalar)

The context in which zle was called to read a line; read-only. One of the values:

CURSOR (integer)

The offset of the cursor, within the edit buffer. This is in the range 0 to $#BUFFER, and is by definition equal to $#LBUFFER. Attempts to move the cursor outside the buffer will result in the cursor being moved to the appropriate end of the buffer.

CUTBUFFER (scalar)

The last item cut using one of the `kill-' commands; the string which the next yank would insert in the line. Later entries in the kill ring are in the array killring. Note that the command ` zle copy-region-as-kill string' can be used to set the text of the cut buffer from a shell function and cycle the kill ring in the same way as interactively killing text.

HISTNO (integer)

The current history number. Setting this has the same effect as moving up or down in the history to the corresponding history line. An attempt to set it is ignored if the line is not stored in the history. Note this is not the same as the parameter HISTCMD, which always gives the number of the history line being added to the main shell's history. HISTNO refers to the line being retrieved within zle.

ISEARCHMATCH_ACTIVE (integer)

ISEARCHMATCH_START (integer)

ISEARCHMATCH_END (integer)

ISEARCHMATCH_ACTIVE indicates whether a part of the BUFFER is currently matched by an incremental search pattern. ISEARCHMATCH_START and ISEARCHMATCH_END give the location of the matched part and are in the same units as CURSOR. They are only valid for reading when ISEARCHMATCH_ACTIVE is non-zero.

KEYMAP (scalar)

The name of the currently selected keymap; read-only.

KEYS (scalar)

The keys typed to invoke this widget, as a literal string; read-only.

KEYS_QUEUED_COUNT (integer)

The number of bytes pushed back to the input queue and therefore available for reading immediately before any I/O is done; read-only. See also PENDING; the two values are distinct.

killring (array)

The array of previously killed items, with the most recently killed first. This gives the items that would be retrieved by a yank-pop in the same order. Note, however, that the most recently killed item is in $CUTBUFFER; $killring shows the array of previous entries.

LASTABORTEDSEARCH (scalar)

The last search string used by an interactive search that was aborted by the user (status 3 returned by the search widget).

LASTSEARCH (scalar)

The last search string used by an interactive search; read-only. This is set even if the search failed (status 0, 1 or 2 returned by the search widget), but not if it was aborted by the user.

LASTWIDGET (scalar)

The name of the last widget that was executed; read-only.

LBUFFER (scalar)

The part of the buffer that lies to the left of the cursor position. If it is assigned to, only that part of the buffer is replaced, and the cursor remains between the new $LBUFFER and the old $RBUFFER.

MARK (integer)

Like CURSOR, but for the mark. With vi-mode operators that wait for a movement command to select a region of text, setting MARK allows the selection to extend in both directions from the initial cursor position.

NUMERIC (integer)

The numeric argument. If no numeric argument was given, this parameter is unset. When this is set inside a widget function, builtin widgets called with the zle builtin command will use the value assigned. If it is unset inside a widget function, builtin widgets called behave as if no numeric argument was given.

PENDING (integer)

The number of bytes pending for input, i.e. the number of bytes which have already been typed and can immediately be read. On systems where the shell is not able to get this information, this parameter will always have a value of zero. Read-only. See also KEYS_QUEUED_COUNT; the two values are distinct.

PREBUFFER (scalar)

In a multi-line input at the secondary prompt, this read-only parameter contains the contents of the lines before the one the cursor is currently in.

PREDISPLAY (scalar)

Text to be displayed before the start of the editable text buffer. This does not have to be a complete line; to display a complete line, a newline must be appended explicitly. The text is reset on each new invocation (but not recursive invocation) of zle.

POSTDISPLAY (scalar)

Text to be displayed after the end of the editable text buffer. This does not have to be a complete line; to display a complete line, a newline must be prepended explicitly. The text is reset on each new invocation (but not recursive invocation) of zle.

RBUFFER (scalar)

The part of the buffer that lies to the right of the cursor position. If it is assigned to, only that part of the buffer is replaced, and the cursor remains between the old $LBUFFER and the new $RBUFFER.

REGION_ACTIVE (integer)

Indicates if the region is currently active. It can be assigned 0 or 1 to deactivate and activate the region respectively. A value of 2 activates the region in line-wise mode with the highlighted text extending for whole lines only; see Character Highlighting below.

region_highlight (array)

Each element of this array may be set to a string that describes highlighting for an arbitrary region of the command line that will take effect the next time the command line is redisplayed. Highlighting of the non-editable parts of the command line in PREDISPLAY and POSTDISPLAY are possible, but note that the P flag is needed for character indexing to include PREDISPLAY.

region_highlight=("P0 20 bold")

registers (associative array)

The contents of each of the vi register buffers. These are typically set using vi-set-buffer followed by a delete, change or yank command.

SUFFIX_ACTIVE (integer)

SUFFIX_START (integer)

SUFFIX_END (integer)

SUFFIX_ACTIVE indicates whether an auto-removable completion suffix is currently active. SUFFIX_START and SUFFIX_END give the location of the suffix and are in the same units as CURSOR. They are only valid for reading when SUFFIX_ACTIVE is non-zero.

UNDO_CHANGE_NO (integer)

A number representing the state of the undo history. The only use of this is passing as an argument to the undo widget in order to undo back to the recorded point. Read-only.

UNDO_LIMIT_NO (integer)

A number corresponding to an existing change in the undo history; compare UNDO_CHANGE_NO. If this is set to a value greater than zero, the undo command will not allow the line to be undone beyond the given change number. It is still possible to use ` zle undo change' in a widget to undo beyond that point; in that case, it will not be possible to undo at all until UNDO_LIMIT_NO is reduced. Set to 0 to disable the limit.

() {
  local UNDO_LIMIT_NO=$UNDO_CHANGE_NO
  # Perform some form of recursive edit.
}

WIDGET (scalar)

The name of the widget currently being executed; read-only.

WIDGETFUNC (scalar)

The name of the shell function that implements a widget defined with either zle -N or zle -C. In the former case, this is the second argument to the zle -N command that defined the widget, or the first argument if there was no second argument. In the latter case this is the third argument to the zle -C command that defined the widget. Read-only.

WIDGETSTYLE (scalar)

Describes the implementation behind the completion widget currently being executed; the second argument that followed zle -C when the widget was defined. This is the name of a builtin completion widget. For widgets defined with zle -N this is set to the empty string. Read-only.

YANK_ACTIVE (integer)

YANK_START (integer)

YANK_END (integer)

YANK_ACTIVE indicates whether text has just been yanked (pasted) into the buffer. YANK_START and YANK_END give the location of the pasted text and are in the same units as CURSOR. They are only valid for reading when YANK_ACTIVE is non-zero. They can also be assigned by widgets that insert text in a yank-like fashion, for example wrappers of bracketed-paste. See also zle -f.

ZLE_RECURSIVE (integer)

Usually zero, but incremented inside any instance of recursive-edit. Hence indicates the current recursion level.

ZLE_STATE (scalar)

Contains a set of space-separated words that describe the current zle state.

if [[ $ZLE_STATE == *globalhistory*insert* ]]; then ...; fi

Special Widgets

zle-isearch-exit

Executed at the end of incremental search at the point where the isearch prompt is removed from the display. See zle-isearch-update for an example.

zle-isearch-update

Executed within incremental search when the display is about to be redrawn. Additional output below the incremental search prompt can be generated by using ` zle -M' within the widget. For example,

zle-isearch-update() { zle -M "Line $HISTNO"; }
zle -N zle-isearch-update

zle-isearch-exit() { zle -M ""; }
zle -N zle-isearch-exit

zle-line-pre-redraw

Executed whenever the input line is about to be redrawn, providing an opportunity to update the region_highlight array.

zle-line-init

Executed every time the line editor is started to read a new line of input. The following example puts the line editor into vi command mode when it starts up.

zle-line-init() { zle -K vicmd; }
zle -N zle-line-init

zle-line-finish

This is similar to zle-line-init but is executed every time the line editor has finished reading a line of input.

zle-history-line-set

Executed when the history line changes.

zle-keymap-select

Executed every time the keymap changes, i.e. the special parameter KEYMAP is set to a different value, while the line editor is active. Initialising the keymap when the line editor starts does not cause the widget to be called.

history-incremental-search-backward (^R ^Xr) (unbound) (unbound)

Search backward incrementally for a specified string. The search is case-insensitive if the search string does not have uppercase letters and no numeric argument was given. The string may begin with ` ^' to anchor the search to the beginning of the line. When called from a user-defined function returns the following statuses: 0, if the search succeeded; 1, if the search failed; 2, if the search term was a bad pattern; 3, if the search was aborted by the send-break command.

zle history-incremental-search-backward forceps

history-incremental-search-forward (^S ^Xs) (unbound) (unbound)

Search forward incrementally for a specified string. The search is case-insensitive if the search string does not have uppercase letters and no numeric argument was given. The string may begin with ` ^' to anchor the search to the beginning of the line. The functions available in the mini-buffer are the same as for history-incremental-search-backward.

history-incremental-pattern-search-backward

history-incremental-pattern-search-forward

These widgets behave similarly to the corresponding widgets with no -pattern, but the search string typed by the user is treated as a pattern, respecting the current settings of the various options affecting pattern matching. See FILENAME GENERATION in zshexpn(1) for a description of patterns. If no numeric argument was given lowercase letters in the search string may match uppercase letters in the history. The string may begin with ` ^' to anchor the search to the beginning of the line.

history-search-backward (ESC-P ESC-p) (unbound) (unbound)

Search backward in the history for a line beginning with the first word in the buffer.

vi-history-search-backward (unbound) (/) (unbound)

history-search-forward (ESC-N ESC-n) (unbound) (unbound)

Search forward in the history for a line beginning with the first word in the buffer.

vi-history-search-forward (unbound) (?) (unbound)

Search forward in the history for a specified string. The string may begin with ` ^' to anchor the search to the beginning of the line. The functions available in the mini-buffer are the same as for vi-history-search-backward. Argument handling is also the same as for that command.

infer-next-history (^X^N) (unbound) (unbound)

Search in the history list for a line matching the current one and fetch the event following it.

insert-last-word (ESC-_ ESC-.) (unbound) (unbound)

Insert the last word from the previous history event at the cursor position. If a positive numeric argument is given, insert that word from the end of the previous history event. If the argument is zero or negative insert that word from the left (zero inserts the previous command word). Repeating this command replaces the word just inserted with the last word from the history event prior to the one just used; numeric arguments can be used in the same way to pick a word from that event.

zle insert-last-word -- -1 -1

zle insert-last-word -- -1 1 -

vi-repeat-search (unbound) (n) (unbound)

Repeat the last vi history search.

vi-rev-repeat-search (unbound) (N) (unbound)

Repeat the last vi history search, but in reverse.

up-line-or-history (^P ESC-[A) (k) (ESC-[A)

Move up a line in the buffer, or if already at the top line, move to the previous event in the history list.

vi-up-line-or-history (unbound) (-) (unbound)

Move up a line in the buffer, or if already at the top line, move to the previous event in the history list. Then move to the first non-blank character on the line.

up-line-or-search

Move up a line in the buffer, or if already at the top line, search backward in the history for a line beginning with the first word in the buffer.

up-history (unbound) (^P) (unbound)

Move to the previous event in the history list.

history-beginning-search-forward

Search forward in the history for a line beginning with the current line up to the cursor. This leaves the cursor in its original position.

set-local-history

By default, history movement commands visit the imported lines as well as the local lines. This widget lets you toggle this on and off, or set it with the numeric argument. Zero for both local and imported lines and nonzero for only local lines.

Exchange the two characters to the left of the cursor if at end of line, else exchange the character under the cursor with the character to the left.

transpose-words (ESC-T ESC-t) (unbound) (unbound)

Exchange the current word with the one before it.

vi-unindent (unbound) (<) (unbound)

Unindent a number of lines.

vi-up-case (unbound) (gU) (unbound)

Read a movement command from the keyboard, and convert all characters from the cursor position to the endpoint of the movement to lowercase. If the movement command is vi-up-case, swap the case of all characters on the current line.

up-case-word (ESC-U ESC-u) (unbound) (unbound)

Convert the current word to all caps and move past it.

yank (^Y) (unbound) (unbound)

Insert the contents of the kill buffer at the cursor position.

yank-pop (ESC-y) (unbound) (unbound)

Remove the text just yanked, rotate the kill-ring (the history of previously killed text) and yank the new top. Only works following yank, vi-put-before, vi-put-after or yank-pop.

vi-yank (unbound) (y) (unbound)

Read a movement command from the keyboard, and copy the region from the cursor position to the endpoint of the movement into the kill buffer. If the command is vi-yank, copy the current line.

vi-yank-whole-line (unbound) (Y) (unbound)

Copy the current line into the kill buffer.

vi-yank-eol

Copy the region from the cursor position to the end of the line into the kill buffer. Arguably, this is what Y should do in vi, but it isn't what it actually does.

Arguments

digit-argument (ESC-0..ESC-9) (1-9) (unbound)

Start a new numeric argument, or add to the current one. See also vi-digit-or-beginning-of-line. This only works if bound to a key sequence ending in a decimal digit.

neg-argument (ESC--) (unbound) (unbound)

Changes the sign of the following argument.

universal-argument

Multiply the argument of the next command by 4. Alternatively, if this command is followed by an integer (positive or negative), use that as the argument for the next command. Thus digits cannot be repeated using this command. For example, if this command occurs twice, followed immediately by forward-char, move forward sixteen spaces; if instead it is followed by -2, then forward-char, move backward two spaces.

argument-base

Use the existing numeric argument as a numeric base, which must be in the range 2 to 36 inclusive. Subsequent use of digit-argument and universal-argument will input a new numeric argument in the given base. The usual hexadecimal convention is used: the letter a or A corresponds to 10, and so on. Arguments in bases requiring digits from 10 upwards are more conveniently input with universal-argument, since ESC-a etc. are not usually bound to digit-argument.

zle argument-base 16
zle universal-argument

Completion

accept-and-menu-complete

In a menu completion, insert the current completion into the buffer, and advance to the next possible completion.

complete-word

Attempt completion on the current word.

delete-char-or-list (^D) (unbound) (unbound)

Delete the character under the cursor. If the cursor is at the end of the line, list possible completions for the current word.

expand-cmd-path

Expand the current command to its full pathname.

expand-or-complete (TAB) (unbound) (TAB)

Attempt shell expansion on the current word. If that fails, attempt completion.

expand-or-complete-prefix

Attempt shell expansion on the current word up to cursor.

expand-history (ESC-space ESC-!) (unbound) (unbound)

Perform history expansion on the edit buffer.

expand-word (^X*) (unbound) (unbound)

Attempt shell expansion on the current word.

list-choices (ESC-^D) (^D =) (^D)

List possible completions for the current word.

list-expand (^Xg ^XG) (^G) (^G)

List the expansion of the current word.

magic-space

Perform history expansion and insert a space into the buffer. This is intended to be bound to space.

menu-complete

Like complete-word, except that menu completion is used. See the MENU_COMPLETE option.

menu-expand-or-complete

Like expand-or-complete, except that menu completion is used.

reverse-menu-complete

Perform menu completion, like menu-complete, except that if a menu completion is already in progress, move to the previous completion rather than the next.

end-of-list

When a previous completion displayed a list below the prompt, this widget can be used to move the prompt below the list.

Miscellaneous

accept-and-hold (ESC-A ESC-a) (unbound) (unbound)

Push the contents of the buffer on the buffer stack and execute it.

accept-and-infer-next-history

Execute the contents of the buffer. Then search the history list for a line matching the current one and push the event following onto the buffer stack.

accept-line (^J ^M) (^J ^M) (^J ^M)

Finish editing the buffer. Normally this causes the buffer to be executed as a shell command.

accept-line-and-down-history (^O) (unbound) (unbound)

Execute the current line, and push the next history event on the buffer stack.

auto-suffix-remove

If the previous action added a suffix (space, slash, etc.) to the word on the command line, remove it. Otherwise do nothing. Removing the suffix ends any active menu completion or menu selection.

auto-suffix-retain

If the previous action added a suffix (space, slash, etc.) to the word on the command line, force it to be preserved. Otherwise do nothing. Retaining the suffix ends any active menu completion or menu selection.

beep

Beep, unless the BEEP option is unset.

bracketed-paste

This widget is invoked when text is pasted to the terminal emulator. It is not intended to be bound to actual keys but instead to the special sequence generated by the terminal emulator when text is pasted.

vi-cmd-mode (^X^V) (unbound) (^[)

Enter command mode; that is, select the `vicmd' keymap. Yes, this is bound by default in emacs mode.

vi-caps-lock-panic

Hang until any lowercase key is pressed. This is for vi users without the mental capacity to keep track of their caps lock key (like the author).

clear-screen (^L ESC-^L) (^L) (^L)

Clear the screen and redraw the prompt.

deactivate-region

Make the current region inactive. This disables vim-style visual selection mode if it is active.

describe-key-briefly

Reads a key sequence, then prints the function bound to that sequence.

exchange-point-and-mark (^X^X) (unbound) (unbound)

Exchange the cursor position (point) with the position of the mark. Unless a negative numeric argument is given, the region between point and mark is activated so that it can be highlighted. If a zero numeric argument is given, the region is activated but point and mark are not swapped.

execute-named-cmd (ESC-x) (:) (unbound)

Read the name of an editor command and execute it. Aliasing this widget with ` zle -A' or replacing it with `zle -N' has no effect when interpreting key bindings, but ` zle execute-named-cmd' will invoke such an alias or replacement.

execute-last-named-cmd (ESC-z) (unbound) (unbound)

Redo the last function executed with execute-named-cmd.

get-line (ESC-G ESC-g) (unbound) (unbound)

Pop the top line off the buffer stack and insert it at the cursor position.

pound-insert (unbound) (#) (unbound)

If there is no # character at the beginning of the buffer, add one to the beginning of each line. If there is one, remove a # from each line that has one. In either case, accept the current line. The INTERACTIVE_COMMENTS option must be set for this to have any usefulness.

vi-pound-insert

If there is no # character at the beginning of the current line, add one. If there is one, remove it. The INTERACTIVE_COMMENTS option must be set for this to have any usefulness.

push-input

Push the entire current multiline construct onto the buffer stack and return to the top-level ( PS1) prompt. If the current parser construct is only a single line, this is exactly like push-line. Next time the editor starts up or is popped with get-line, the construct will be popped off the top of the buffer stack and loaded into the editing buffer.

push-line (^Q ESC-Q ESC-q) (unbound) (unbound)

Push the current buffer onto the buffer stack and clear the buffer. Next time the editor starts up, the buffer will be popped off the top of the buffer stack and loaded into the editing buffer.

push-line-or-edit

At the top-level (PS1) prompt, equivalent to push-line. At a secondary ( PS2) prompt, move the entire current multiline construct into the editor buffer. The latter is equivalent to push-input followed by get-line.

read-command

Only useful from a user-defined widget. A keystroke is read just as in normal operation, but instead of the command being executed the name of the command that would be executed is stored in the shell parameter REPLY. This can be used as the argument of a future zle command. If the key sequence is not bound, status 1 is returned; typically, however, REPLY is set to undefined-key to indicate a useless key sequence.

recursive-edit

Only useful from a user-defined widget. At this point in the function, the editor regains control until one of the standard widgets which would normally cause zle to exit (typically an accept-line caused by hitting the return key) is executed. Instead, control returns to the user-defined widget. The status returned is non-zero if the return was caused by an error, but the function still continues executing and hence may tidy up. This makes it safe for the user-defined widget to alter the command line or key bindings temporarily.

return $stat

redisplay (unbound) (^R) (^R)

Redisplays the edit buffer.

reset-prompt (unbound) (unbound) (unbound)

Force the prompts on both the left and right of the screen to be re-expanded, then redisplay the edit buffer. This reflects changes both to the prompt variables themselves and changes in the expansion of the values (for example, changes in time or directory, or changes to the value of variables referred to by the prompt).

send-break (^G ESC-^G) (unbound) (unbound)

Abort the current editor function, e.g. execute-named-command, or the editor itself, e.g. if you are in vared. Otherwise abort the parsing of the current line; in this case the aborted line is available in the shell variable ZLE_LINE_ABORTED. If the editor is aborted from within vared, the variable ZLE_VARED_ABORTED is set.

run-help (ESC-H ESC-h) (unbound) (unbound)

Push the buffer onto the buffer stack, and execute the command ` run-help cmd', where cmd is the current command. run-help is normally aliased to man.

vi-set-buffer (unbound) (") (unbound)

Specify a buffer to be used in the following command. There are 37 buffers that can be specified: the 26 `named' buffers "a to "z, the `yank' buffer "0, the nine `queued' buffers "1 to "9 and the `black hole' buffer "_. The named buffers can also be specified as "A to "Z.

zle vi-set-buffer A

vi-set-mark (unbound) (m) (unbound)

Set the specified mark at the cursor position.

set-mark-command (^@) (unbound) (unbound)

Set the mark at the cursor position. If called with a negative numeric argument, do not set the mark but deactivate the region so that it is no longer highlighted (it is still usable for other purposes). Otherwise the region is marked as active.

spell-word (ESC-$ ESC-S ESC-s) (unbound) (unbound)

Attempt spelling correction on the current word.

split-undo

Breaks the undo sequence at the current change. This is useful in vi mode as changes made in insert mode are coalesced on entering command mode. Similarly, undo will normally revert as one all the changes made by a user-defined widget.

undefined-key

This command is executed when a key sequence that is not bound to any command is typed. By default it beeps.

undo (^_ ^Xu ^X^U) (u) (unbound)

Incrementally undo the last text modification. When called from a user-defined widget, takes an optional argument indicating a previous state of the undo history as returned by the UNDO_CHANGE_NO variable; modifications are undone until that state is reached, subject to any limit imposed by the UNDO_LIMIT_NO variable.

redo (unbound) (^R) (unbound)

Incrementally redo undone text modifications.

vi-undo-change (unbound) (unbound) (unbound)

Undo the last text modification. If repeated, redo the modification.

visual-mode (unbound) (v) (unbound)

Toggle vim-style visual selection mode. If line-wise visual mode is currently enabled then it is changed to being character-wise. If used following an operator, it forces the subsequent movement command to be treated as a character-wise movement.

visual-line-mode (unbound) (V) (unbound)

Toggle vim-style line-wise visual selection mode. If character-wise visual mode is currently enabled then it is changed to being line-wise. If used following an operator, it forces the subsequent movement command to be treated as a line-wise movement.

what-cursor-position (^X=) (ga) (unbound)

Print the character under the cursor, its code as an octal, decimal and hexadecimal number, the current cursor position within the buffer and the column of the cursor in the current line.

where-is

Read the name of an editor command and print the listing of key sequences that invoke the specified command. A restricted set of editing functions is available in the mini-buffer. Keys are looked up in the special command keymap, and if not found there in the main keymap.

which-command (ESC-?) (unbound) (unbound)

Push the buffer onto the buffer stack, and execute the command ` which-command cmd'. where cmd is the current command. which-command is normally aliased to whence.

vi-digit-or-beginning-of-line (unbound) (0) (unbound)

If the last command executed was a digit as part of an argument, continue the argument. Otherwise, execute vi-beginning-of-line.

Text Objects

select-a-blank-word (aW)

Select a word including adjacent blanks, where a word is defined as a series of non-blank characters. With a numeric argument, multiple words will be selected.

select-a-shell-word (aa)

Select the current command argument applying the normal rules for quoting.

select-a-word (aw)

Select a word including adjacent blanks, using the normal vi-style word definition. With a numeric argument, multiple words will be selected.

select-in-blank-word (iW)

Select a word, where a word is defined as a series of non-blank characters. With a numeric argument, multiple words will be selected.

select-in-shell-word (ia)

Select the current command argument applying the normal rules for quoting. If the argument begins and ends with matching quote characters, these are not included in the selection.

select-in-word (iw)

Select a word, using the normal vi-style word definition. With a numeric argument, multiple words will be selected.

CHARACTER HIGHLIGHTING

default

Any text within the command line not affected by any other highlighting. Text outside the editable area of the command line is not affected.

isearch

When one of the incremental history search widgets is active, the area of the command line matched by the search string or pattern.

region

The currently selected text. In emacs terminology, this is referred to as the region and is bounded by the cursor (point) and the mark. The region is only highlighted if it is active, which is the case after the mark is modified with set-mark-command or exchange-point-and-mark. Note that whether or not the region is active has no effect on its use within emacs style widgets, it simply determines whether it is highlighted. In vi mode, the region corresponds to selected text in visual mode.

special

Individual characters that have no direct printable representation but are shown in a special manner by the line editor. These characters are described below.

suffix

This context is used in completion for characters that are marked as suffixes that will be removed if the completion ends at that point, the most obvious example being a slash ( /) after a directory name. Note that suffix removal is configurable; the circumstances under which the suffix will be removed may differ for different completions.

paste

Following a command to paste text, the characters that were inserted.

fg_start_code (\e[3)

The start of the escape sequence for the foreground colour. This is followed by an ASCII digit representing the colour.

fg_default_code (9)

The number to use instead of the colour to reset the default foreground colour.

fg_end_code (m)

The end of the escape sequence for the foreground colour.

bg_start_code (\e[4)

The start of the escape sequence for the background colour. This is followed by an ASCII digit representing the colour.

bg_default_code (9)

The number to use instead of the colour to reset the default background colour.

bg_end_code (m)

The end of the escape sequence for the background colour.

none

No highlighting is applied to the given context. It is not useful for this to appear with other types of highlighting; it is used to override a default.

fg=colour

The foreground colour should be set to colour, a decimal integer or the name of one of the eight most widely-supported colours.

bg=colour

The background colour should be set to colour. This works similarly to the foreground colour, except the background is not usually affected by the bold attribute.

bold

The characters in the given context are shown in a bold font. Not all terminals distinguish bold fonts.

standout

The characters in the given context are shown in the terminal's standout mode. The actual effect is specific to the terminal; on many terminals it is inverse video. On some such terminals, where the cursor does not blink it appears with standout mode negated, making it less than clear where the cursor actually is. On such terminals one of the other effects may be preferable for highlighting the region and matched search string.

underline

The characters in the given context are shown underlined. Some terminals show the foreground in a different colour instead; in this case whitespace will not be highlighted.

ASCII control characters

Control characters in the ASCII range are shown as ` ^' followed by the base character.

Unprintable multibyte characters

This item applies to control characters not in the ASCII range, plus other characters as follows. If the MULTIBYTE option is in effect, multibyte characters not in the ASCII character set that are reported as having zero width are treated as combining characters when the option COMBINING_CHARS is on. If the option is off, or if a character appears where a combining character is not valid, the character is treated as unprintable.

Invalid multibyte characters

If the MULTIBYTE option is in effect, any sequence of one or more bytes that does not form a valid character in the current character set is treated as a series of bytes each shown as a special character. This case can be distinguished from other unprintable characters as the bytes are represented as two hexadecimal digits between angle brackets, as distinct from the four or eight digits that are used for unprintable characters that are nonetheless valid in the current character set.

Wrapped double-width characters

When a double-width character appears in the final column of a line, it is instead shown on the next line. The empty space left in the original position is highlighted as a special character.
