Keyboard settings for IDEA under Ubuntu

HI

I have a vanilla install of IDEA 7 M1 on Ubuntu Feisty, wondering if anyone has come up with sensible keyboard mappings? Ctl-Alt-L locks the screen instead of formatting the code, Ctl-Alt-Left switches workspaces instead of navigating backwardsI know how to change the key mappings, I just don't want to struggle and come up with yet another set that is unique to this instance of the editorwhat do you all do?


Thanks
Patrick
