Well, Now I Know NOT To Try THAT At Home!

In an effort to perform some function on my computer, I accidentally hit some combination of CTRL and ALT and an arrow key--and my entire screen turned upside down.

I have enough trouble working without adding THAT little feature to my workday.

Fortunately, I have another computer, so I went to it and Googled "screen upside down." And, in short order, I was able to fix the screen that was catty-wompus.

Whew!
