I recently found the handy CTRL+Shift+Power key combination to lock (not put to sleep you entire mac!) your screen. Is there a way to reconfigure the power key to use that key combo? This in combination with requiring your password immediately after sleeping or screen saver beginning works well when you need to step away from your mac for a bit. Note that I'm not talking about putting the mac to sleep, but just locking the screen (locking the screen just turns off the display while the mac is completely active in the background). Thanks all!
