Hi friends,

I'm a teacher who has some students that like to mess around with the macbook laptops (their favorite is control-option-command-8) and change settings, etc. I've blocked them out of System Preferences already but some keyboard shortcuts I'm not sure what to do about. I figure I could just disable them, but what I'd really like to do for repeat offenders is set a trap so that when they do their favorite keyboard shortcut they see a screen that says "You've violated school laptop policy, please see Sister for your discipline point!". Then I can either have mercy on them or really give them the d.p., but at least they know they've been "busted."

Any tips on making this possible?
