Because I always forget how I did this, I’m going to write it down. Firstly, I spend a lot of time in Terminals, so I like having a quick shortcut to use to open one. Control + Super seemed a good choice for this.

Unfortunately, the keyboard shortcut tool doesn’t let you map the Super button anymore, so to set it we need to use gconf. Open gconf-editor and go to /apps/metacity/globalkeybindings/ and look for the option named “run_command_terminal” you can set it here by changing the value to “<Control>Super_L”; in this case it will work with the left windows key.

Another issue I found again today after opening Blender again for the first time in a long while, was that  Alt+RMB (edge ring select) gets stolen by Compiz and turned into a Menu popup instead. This can be fixed in gconf as well by going to /apps/compiz/general/allscreens/options/ and changing the value for window_menu_button to “<Control><Alt>Button3″.
