How to unbind K-menu from Win keys?

[Felix Homann <fexpop@onlinehome.de>]

Hi,

I used to bind some xemacs functions on keyboard shortcuts involving the Super 
keys (i.e. Win keys). KDE blocks them by popping up the K-menu. I couldn't 
get rid of this annoying behaviour. There doesn't seem to be an entry in the 
"Keyboard Shortcuts" part of the Control Center.

Any idea?

Thanks in advance,

Felix
