OpenSUSE :: Remap A Single Key (or Keymapping In General)?

I want to remap a single key on my keyboard. This is the key which will delete or in numpad mode will put a '.' or a ',' in my case.I want the ',' to be a '.' .So I found out that xev gives me some information about the keys.So I tried something likexmodmap -e 'keycode 91 = period'Which is not what I want. Because than the delete command gets overwritten instead of the comma. So I triedxmodmap -e 'keysym 0x0 = period'Which looked like a endless loop to me. 0x0 is also quite strange, isn't it? But this is what xev gave me for numlock activated and the comma-key.The difference between the delete and the comma is the "state".Xev returns for delete:

Code:
KeyRelease event, serial 34, synthetic NO, window 0x4800001,
root 0x10c, subw 0x0, time 1934052, (412,580), root:(416,605),
