I can officially say it's been a loooong time since I used Windows. Out of habit I hit ctrl-alt-right arrow on the keyboard to switch to a different workspace, since I had just kicked off a long running job and wanted to open another ssh session to work on another project, and the screen on my laptop went sideways. It was early on a Sunday AM and I hadn't had a second cup of coffee, so I was a little more surprised and confused than I normally would be at such an event. I tried ctrl-alt-left arrow and it flipped it the other way. Ctrl-alt-down flipped it upside down, so I tried the only remaining combo: ctrl-alt-up, which made everything hunky-dory again.
I suppose if I am ever forced to use Windows Vespa I'm going to lose what's left of my mind.
