Changing keyboard layouts (repost)

[Tal Eisenberg <eisental@012.net.il>]

Not being aware of the "thread-steling" thing before, I'm reposting my message 
on a new thread (I hope it's okay...)

I'm using kde 3.1.2 with kxkb setup for hebrew and english. I just bought 
a new keyboard with some extra buttons (play, stop, etc.). I've created a 
xmodmap file to get the keys working but everytime I switch between keyboard 
layouts that xmodmap modifications get erased and I need to run xmodmap 
again. Is there a way to make permanent changes to the layouts of both hebrew 
and english in kxkb?

TIA, Tal
