Remapping keys in KDE (4.8.5, Kubuntu 12.04)

Remapping keys in KDE (4.8.5, Kubuntu 12.04)

I have been remapping keys via xmodmap commands but this doesn't appear to
be very satisfactory on my Kubuntu 12.04. The problem is that when I sleep
my computer and then log back in again, everything goes back to what KDE
thinks it should be.
The behaviour I'm trying to change is that configured in the System
Settings -> Input Devices -> Keyboard -> Advanced -> Alt/Win key
behaviour. I would use that but they don't have the options I want... It
must be easily configurable though - if they are doing it there then it
must be possible!
Thanks.
(ps. this is not the same as my META problem - I have decided I'm going to
stick with VIM :-))
