Remap Mod4

[Ralph Hofmann <hofmann2004 arcor de>]

Is it possible to map the mod4 key (windows key on the left) to another 
key, for example the windows key on the right?

In my Gnome2 setup, I am using many key combinations with mod4 and I 
don't want to change that, but most of the combinations with mod4 
obviously don't work anymore.
