So the webpage you’re viewing too long for you to keep on scrolling down? Or maybe you just want to show off and hold your Eee like a book? This Windows utility called EeeRotate that can rotate your Eee PC screen to whatever direction you want.
According to Liliputing,
The program also lets you rotate your screen with a handful of keyboard shortcuts. Ctrl+Alt+Right will rotate your screen by 90 degrees. Ctrl+Alt+Down will give you a 180 degree rotation (turning the screen upside down), and Ctrl+Alt+Left rotates your screen by 270 degrees.
