     (-a | --all | [(-k | --key)] SEQUENCE [SEQUENCE...])

  Description
bind adds a binding for the specified key sequence to the specified command.

SEQUENCE is the character sequence to bind to. These should be written as fish escape sequences. For example, because pressing the Alt key and another character sends that character prefixed with an escape character, Alt-based key bindings can be written using the \e escape. For example, [Alt-w] can be written as \ew. The control character can be written in much the same way using the \c escape, for example [Control-X] (^X) can be written as \cx. Note that Alt-based key bindings are case sensitive and Control-based key bindings are not. This is a constraint of text-based terminals, not fish.

The default key binding can be set by specifying a SEQUENCE of the empty string (that is, '' ). It will be used whenever no other binding matches. For most key bindings, it makes sense to use the self-insert function (i.e. bind '' self-insert) as the default keybinding. This will insert any keystrokes not specifically bound to into the editor. Non- printable characters are ignored by the editor, so this will not result in control sequences being printable.

If the -k switch is used, the name of the key (such as 'down', 'up' or 'backspace') is used instead of a sequence. The names used are the same as the corresponding curses variables, but without the 'key_' prefix. (See terminfo(5) for more information, or use bind --key-names for a list of all available named keys.)

COMMAND can be any fish command, but it can also be one of a set of special input functions. These include functions for moving the cursor, operating on the kill-ring, performing tab completion, etc. Use bind --function-names for a complete list of these input functions.

When COMMAND is a shellscript command, it is a good practice to put the actual code into a function and simply bind to the function name. This way it becomes significantly easier to test the function while editing, and the result is usually more readable as well.

If such a script produces output, the script needs to finish by calling commandline -f repaint in order to tell fish that a repaint is in order.

When multiple COMMANDs are provided, they are all run in the specified order when the key is pressed.

If no SEQUENCE is provided, all bindings (or just the bindings in the specified MODE) are printed. If SEQUENCE is provided without COMMAND, just the binding matching that sequence is printed.

Key bindings are not saved between sessions by default. To save custom keybindings, edit the fish_user_key_bindings function and insert the appropriate bind statements.

Key bindings may use 'modes', which mimics Vi's modal input behavior. The default mode is 'default', and every bind applies to a single mode. The mode can be viewed/changed with the $fish_bind_mode variable.

The following parameters are available:

•   -k or --key Specify a key name, such as 'left' or 'backspace' instead of a character sequence

•   -K or --key-names Display a list of available key names. Specifying -a or --all includes keys that don't have a known mapping

•   -f or --function-names Display a list of available input functions

•   -M MODE or --mode MODE Specify a bind mode that the bind is used in. Defaults to 'default'

•   -m NEW_MODE or --sets-mode NEW_MODE Change the current mode to NEW_MODE after this binding is executed

•   -e or --erase Erase the binding with the given sequence and mode instead of defining a new one. Multiple sequences can be specified with this flag. Specifying -a or --all with -M or --mode erases all binds in the given mode regardless of sequence. Specifying -a or --all without -M or --mode erases all binds in all modes regardless of sequence.

•   -a or --all See --erase and --key-names

The following special input functions are available:

•   backward-char, moves one character to the left

•   backward-delete-char, deletes one character of input to the left of the cursor

•   backward-kill-line, move everything from the beginning of the line to the cursor to the killring

•   backward-kill-word, move the word to the left of the cursor to the killring

•   backward-word, move one word to the left

•   beginning-of-history, move to the beginning of the history

•   beginning-of-line, move to the beginning of the line

•   capitalize-word, make the current word begin with a capital letter

•   complete, guess the remainder of the current token

•   delete-char, delete one character to the right of the cursor

•   delete-line, delete the entire line

•   downcase-word, make the current word lowercase

•   dump-functions, print a list of all key-bindings

•   end-of-history, move to the end of the history

•   end-of-line, move to the end of the line

•   explain, print a description of possible problems with the current command

•   forward-char, move one character to the right

•   forward-word, move one word to the right

•   history-search-backward, search the history for the previous match

•   history-search-forward, search the history for the next match

•   kill-line, move everything from the cursor to the end of the line to the killring

•   kill-whole-line, move the line to the killring

•   kill-word, move the next word to the killring

•   upcase-word, make the current word uppercase

•   yank, insert the latest entry of the killring into the buffer

•   yank-pop, rotate to the previous entry of the killring

  Examples

bind \cd 'exit'

 Causes fish to exit when [Control-D] is pressed.

bind -k ppage history-search-backward

 Performs a history search when the [Page Up] key is pressed.

set -g fish_key_bindings fish_vi_key_bindings
bind -M insert \cc kill-whole-line force-repaint

 Turns on Vi key bindings and rebinds [Control-C] to clear the input line.
