[Grml] C-M emacs key binding conflicts with fluxbox window manager

[Peter]

Hi

I am using emacs 22.1.1 (GTK+ version) in a fluxbox environment.
There are conflicts with C-M emacs bindings and the window manager.

When I type for example C-M-f  in emacs (that is Control key and Alt key 
pressed simultaneously and then followed by the key "f"), then the 
firefox webbrowser opens. Obviously the window manager sees the key 
sequence before emacs and intercepts it.

What is the recommended practice to maintain C-M emacs key bindings 
(remapping them all would be a pain) when working in fluxbox ?

Thanks for your help.

Peter
