Hello,
I'd like to trace whenever a key-binding is being overwritten, and
eventually forbidding some overwrites.
My understanding is that both "global-set-key" and "local-set-key"
rely on "define-key", therefore I've written this advice:
(defadvice define-key (around protect-bindings
(keymap key def)
activate) ;; I'm using an "around"
advice to eventually disable the overwrite.
(when (key-binding-exists key keymap) ;; For "key-binding-exists",
read on.
(message "Overwriting %S binding." key))
ad-do-it)
I don't know how to write the "key-binding-exists" function.
Or it would be better to follow a different route altogether?
Thanks.

Hmm
C-h k and C-h c are bound to
`describe-key' and `describe-key-briefly'
did you try using this?
