I don't know what just happened to my Mac. I was using pages, and made an attempt at a keyboard shortcut: apple + ctr + shift + = I thought this was going invoke a superscript, but that's not what I got. Instead, the whole gui went screwy. Moving the cursor down (via my pb's trackpad) sent the whole screeneverythingup. The menu bar even went off the top of the screen. "Mousing up" brought everything in the screen back down. The computer still worked, it just was funny. Rebooting fixed it. I can't replicate it. Any idea what this was?
