Where do you add key bindings for a mode made with define-derived-mode

Where do you add key bindings for a mode made with define-derived-mode

[Lennart Borgman]

Do you do that after the defining the major mode (i.e. when loading
the library where it is defined) or is there another way?

It think it is up to you.

define-derived-mode uses

 (defvar some-major-mode-map (make-sparse-keymap))

The usual way:

   (defvar foo-mode-map
     (let ((map (make-sparse-keymap)))
       (define-key map foo bar)
       map))
   
   (define-derived-mode foo-mode ...)

Tho, maybe I simply misunderstood your question.

No, you did not but I seem to misunderstand something. Why does that
work? In the code for define-derived-mode there is:

       (defvar ,map (make-sparse-keymap))

Oh, wait! That is what always has surprised me. This statement does
not do anything when the variable is defined...

Hm, thanks, back to the code I wrote long ago. Now I have one thing
less to look at. But I still can't see how (provide 'nxml-mode) can be
passed without nxml-mode-map being defined. I will have to dig a bit.
