I was reading a forum post and wanted to return to the Posts listing using the Alt+Left Arrow.

I don't know which keys I ended up pressing but my screen suddenly rotated 90o to the left...
I googled to find out how I could rotate the screen back:

Ctrl+Alt+Up Arrow returns your screen to its normal upright rotation,
Ctrl+Alt+Right Arrow rotates your screen 90 degrees, Ctrl+Alt+Down Arrow flips it upside down (180 degrees), and Ctrl+Alt+Left Arrow rotates it 270 degrees.


I thought I would test these to see if it could correct the orientation of pics showing the wrong way in some of the forum's threads...It works!!!

Don't forget to reverse the process once you have finished, otherwise your entire screen will be the "wrong way".
