Binding Keys
------------

   You associate keys with functions through the keymap.  Readline has
several internal keymaps: `emacs_standard_keymap', `emacs_meta_keymap',
`emacs_ctlx_keymap', `vi_movement_keymap', and `vi_insertion_keymap'.
`emacs_standard_keymap' is the default, and the examples in this manual
assume that.

   These functions manage key bindings.

 - Function: int rl_bind_key (int key, Function *function)
     Binds KEY to FUNCTION in the currently active keymap.  Returns
     non-zero in the case of an invalid KEY.

 - Function: int rl_bind_key_in_map (int key, Function *function,
          Keymap map)
     Bind KEY to FUNCTION in MAP.  Returns non-zero in the case of an
     invalid KEY.

 - Function: int rl_unbind_key (int key)
     Bind KEY to the null function in the currently active keymap.
     Returns non-zero in case of error.

 - Function: int rl_unbind_key_in_map (int key, Keymap map)
     Bind KEY to the null function in MAP.  Returns non-zero in case of
     error.

 - Function: int rl_generic_bind (int type, char *keyseq, char *data,
          Keymap map)
     Bind the key sequence represented by the string KEYSEQ to the
     arbitrary pointer DATA.  TYPE says what kind of data is pointed to
     by DATA; this can be a function (`ISFUNC'), a macro (`ISMACR'), or
     a keymap (`ISKMAP').  This makes new keymaps as necessary.  The
     initial keymap in which to do bindings is MAP.

 - Function: int rl_parse_and_bind (char *line)
     Parse LINE as if it had been read from the `inputrc' file and
     perform any key bindings and variable assignments found (
see Readline Init File.).

 - Function: int rl_read_init_file (char *filename)
     Read keybindings and variable assignments from FILENAME (
see Readline Init File.).
