Intel Graphic - Rotate / Flip Screen shortcut

I just found the following shortcuts to flip or rotate the screen.

Just press
STRG + ALT + Arrow Keys:

• UP : rotate 0° (normal position)
• RIGHT: rotate 270°
• DOWN: rotate 180°
• LEFT: rotate 90°

These shortcuts should work with many of the newer Intel Graphic Chipsets when the original drivers are installed.
