Keyboard Layout Remap

[Vdue]

Just downloaded and installed Mint 14. Besides OSX, Win8 it is the third OS on this computer. Installation language is english, keyboard layout is Swiss German Macintosh. The problem I am having is that the keys '§°' and '<>' are mixed. Is there a tool to re-map the keyboard layout ?

Thanks in advance.

Otherwise I am semi happy. 3 hours back in the Linux world and 3crashes
