Keyboard "extra" keys assignment

Hi Is there a way to make those "extra" keys on keyboard to start for example konqueror with parameters? I know the scan-code (from xev). For example in Locitech i-keyboard there is "E-mail" key, with scan code 236. I would like to make it start k-mail... how to do this in SuSE 9.0 / KDE? Jaska.
