Compiz and Gnome have many keyboard shortcuts. Examples are `Ctrl`+`Alt`+`L` for locking the session or `Ctrl`+`Alt`+`Arrows` for switching workspaces. Often they overwrite shortcuts in applications. It would be nice to have a way to temporarily disable these system shortcuts to make way for application shortcuts. Best thing would be to have a shortcut for doing so. :)

Any solutions, ideas?
