How to change key bindings in a particular mode

How to change key bindings in a particular mode

[Guo Qiang]

Hi, all

I am now writing a small function for mew. I want to remake
key bingings to a function in mew's draft mode. How can I do
that ?

Thank you

1. Find the name of the mode: `C-h v major-mode'. Example: `foo-mode'.

2. The mode's keymap is probably the same, with `-map' appended. Example:
`foo-mode-map'.

3. Define or redefine each of the keys you want in that map, using function
`define-key'. Example: (define-key foo-mode-map "\C-a" 'my-cmd)

To see the key bindings for a mode, use `C-h b'.

To better see the key bindings in a particular keymap, use `describe-keymap',
avaiable in library `help-fns+.el':

Just a short addition: Instead of using somewhat special keybinding
syntax like "\C-a", you can also use (kbd "C-a").  This has the benefit
that the `kbd' macro accepts the keys exactly as they're printed by the
help commands (like `C-h k' and `C-h b').
