now, I know, why it worked before. I used three different
distribution: one at work, which is an old redhat 4.3, the other on
my laptop with a recent kubuntu on it and the a scientific linux
(redhat 4.4 clone) on my desktop. And the problem is that on  my
office machine none of the two 'control' combinations work:

   if keyname == "l" and
     (event.state & gtk.gdk.CONTROL_MASK) == gtk.gdk.CONTROL_MASK:
 		do_control_l()
   if keyname == "l" and (event.state & gtk.gdk.CONTROL_MASK) == 0:
 		do_l()

They work on my desktop machine with the same 2.4.1 and python 2.5
version as at the office. Strange!?
Do you have any idea, what goes wrong?

Greetings!
