This is what I currently use, with a simple (use-local-map ...) in the

This what I used in window-edit -- but this is history now.

Ok, thanks for the explanations.

Which are some of the reasons why I switched back to the other solution.

I gave overriding-terminal-local-map a try. 

The problem is that when `window-resize-mode' sends an error, the point
goes in the minibuffer and the active keymap is still the one defined by
`overriding-terminal-local-map'.  This is rather confusing since
window-resize-mode-map redefines the arrow keys and that these keys
might be useful in the minibuffer.  I don't know how to avoid this.

Another question about keymaps in general: in window-resize-mode the
buffer is read-only and I'd like to prevent errors to be thrown when the
user hits a key that should insert itself in another mode.  

So I tried to substitute 'self-insert-command with a variant of my own,
with 'self-insert-command in (ignore-errors ...) or (condition-case...).
But it seems then that those keys which are bound to a command -- other
than 'self-insert-command -- are not working anymore.  

Do you have an idea?
