Use Your Unused Shift Key As a Mission Control Shortcut

If you find you always use the left Shift key, or the right one, for that matter, and never the other Shift key, you use that large unused key as a Mission Control shortcut. Go to System Preferences, Mission Control. In any of the keyboard shortcuts you can change the option to the left or right Shift keys. You can also use any Option, Control or Command key too.
