Disabling all keybindings - How?

Disabling all keybindings - How?

[Klaus Berndl]

I want to write a very small major-mode with only very few senseful
keybindings (e.g.: v, h, c, q, s). I want to disable all other keybindings of
Emacs because they make really no sense (A new frame is started with a new
buffer in this major-mode, some actions have to be performed by the user
(e.g.: hitting v or h), stuff is saved by hitting s and then we quit by
hitting q (which deletes the new frame) - That's all.

OK, now my question: How to disable all Emacs-keybindings for my new
major-mode? Is this possible with one command?

many thanks in advance,
Klaus

You probably want `make-sparse-keymap'.  And now for a bit of fun --
Erik Naggum's poor man's vi-mode:

| e.g., you can do this to get into "poor man's vi-mode":
|
|    (use-global-map (make-sparse-keymap))
|
| like vi, it will beep at everything you do, and you can't quit.  have fun!

You can try

   (defvar bla-mode-map
     (let ((map (make-sparse-keymap)))
       (define-key map "v" 'bla-v-command)
       ...
       (define-key map "s" 'bla-s-command)
       ;; `t' is a special "default" binding.
       (define-key map [t] 'undefined)
       map))

it will prevent function-key-map from doing its job, tho since
all keys will be considered bound to `undefined'.
You might also have some problems with the fact that frame
switches (with the mouse) go through a `switch-frame' event,
so you might want to explicitly bind it to nil to make sure
that its binding in the global map is used.
