Unearthed! System Preferences Keyboard shortcuts

Last night, I was trying to shutdown my computer with an Apple Wireless keyboard. It has no power key so I was trying different shortcuts. Option-F12 brought up something interesting (F12 is not really F12, but the "volume up" command). Holding option with it brought up System Preferences and switched directly to the "Sound" preference. This works with most of the "special keys". Here's the list...

Sound -> option + <volume-up/down/mute>

Spaces -> option + <Dashboard/Spaces>

Display -> option + <Brightness Up/Down>
