My sister just called me with a problem. She was trying to take a screenshot, and instead hit "shift control f4" (or so she thinks). Now around whatever she selects is a black outline. It happens around icons, application windows, and text fields. I couldnt find this command on apple's support page, and hitting the same command wouldn't fix it. I'm at work right now, but I can upload pictures when I get home if needed.....she has a 2 month old MBP if it matters.
