gnus: how to redefine a keymap

[Francis Moreau]

hello,

I'd like to redefine the 'g' key in the group buffer so it queries
only groups with a specific level or lower.

To do that I tried this:

(defun my-gnus-group-get-new-news ()
  (interactive)
  (gnus-group-get-new-news 2))

(add-hook 'gnus-group-mode-hook
          (lambda ()
            (define-key gnus-group-mode-map
              [g] 'my-gnus-group-get-new-news)))

but it doesn't work.

If I map my-gnus-group-get-new-news function to 'F6' for example it
works.

Could anybody tell me why it doesn't work with 'g' key ?

Thanks

How about:

.... [(g)] .....

or .... [?g]....

or .... "g" .....

Because `g' is a symbol, not a character.  On the other hand, function
keys are mapped by symbols (like 'F6).  

Anyway you should probablly stick to the `kbd' macro,  where you can
, in most cases, declare the key as you seem to expect.


(kbd "g")
(kbd "C-g")

Keys which are represented by symbols (e.g. function keys,Home,etc.)
need to be embraced.

(kbd "<f6>")
(kbd "C-<f6>")

Just out of curiosity, why the 2nd one ? it looks to me the less
readable :)
