The <tt>bind</tt> builtin causes fish to add the readline style bindings specified by <tt>BINDINGS</tt> to the list of key bindings. For more information on specifying keyboard bindings, use <tt>man readline</tt> to access the readline documentation.
The <tt>bind</tt> builtin causes fish to add the readline style bindings specified by BINDINGS to the list of key bindings, as if they appeared in your <tt>~/.fish_inputrc</tt> file.
For more information on the syntax keyboard bindings, use <tt>man
readline</tt> to access the readline documentation. The availiable commands
are listed in the <a href="index.html#editor">Command Line Editor</a> section
of the fish manual - but you may also use any fish command! To write such
commands, see the <a href="#commandline">commandline</a> builtin. It's good
practice to put the code into a <tt><a href="#function">function</a> -b</tt>
and bind to the function name.
\subsection bind-description Description
- <tt>-M MODE</tt> or <tt>--set-mode=MODE</tt> sets the current input mode to MODE.

syntax may look a bit like C switch statements, it behaves more like
the case stamantes of traditional shells.
Also note that command substitutions in a case statement will be
evaluated even if it's body is not taken. This may seem
counterintuitive at first, but it is unavoidable, since it would be
impossible to know if a case command will evaluate to true before all
forms of parameter expansion have been performed for the case command.
