Screen Rotation - Use Hot Keys - ideal for e-book reading

I've had my AA1 for a couple of weeks now and downloaded some reading material (e-books).

Rather than view them in landscape I decided to investigate rotating the screen to show the window in portrait mode.

Instead of installing a special app e.g. irotate - http://www.entechtaiwan.com/util/irotate.shtm

It turns out that the intel display driver already installed in my AA1 has this feature readily available via hotkeys.

To access, right click the mouse on the desktop, this will display Graphics Properties..... and Graphics Options

Under Graphics Options>Display Settings check off "Enable Rotation".
Under Graphics Options>Hot keys check off "Enable Hot Keys".

Now Ctl+Alt+ the up/down/left/right keys rotate the screen as desired.

Also selecting Graphic Options after right clicking the mouse displays screen rotation.

 

Thanks. Very cool. I found these settings are under Graphics Properties, not Options, though.

Now, how can you rotate scrolling in the touchpad to match?
