I use a macbook pro for my main machine but also have a Ubuntu desktop. I get irritated about switching between command oriented hotkeys and ctrl oriented hotkeys (cmd-a on OSX = ctrl-a on Linux/windows).

I've looked over a lot of forums and have found that Gnome doesn't seem capable of changing hotkeys while xfce and fluxbox can. The ideal solution would be a way to change system keys in X or at the system level that way I can keep compiz.

Does anyone have any ideas or know a trick to change system hot keys?
