Question 3

Question 3

On my machine, the function keys f11 and f12 are intercepted by the operating system, and emacs doesn't respond to them.

Answer

You could bind those two functions to different key sequences by putting lines like this in your .emacs init file (in your home directory).

 (global-set-key [ (control c) (m) ] 'M2)
 (global-set-key [ (control c) (c) ] 'M2-send-to-program)

Or you could bind them to different function keys like this:

 (global-set-key [ f9 ] 'M2)
 (global-set-key [ f10 ] 'M2-send-to-program)
