 SEQUENCE is the character sequence to bind to. These should be written as <a href="index.html#escapes">fish escape sequences</a>. 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, @key{Alt,w} can be written as `\ew`. The control character can be written in much the same way using the `\c` escape, for example @key{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`.

 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.

+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.
