Basic navigation Windows 8
Windows 8 launches with its new Metro interface, all colourful tiles and touch-friendly apps. And if you're using a tablet then it'll all be very straightforward: just swipe left or right to scroll the screen, and tap any tile of interest.
On a regular desktop, though, you might alternatively spin the mouse wheel to scroll backwards and forwards.
And you can also use the keyboard. Press the Home or End keys to jump from one end of your Start screen to the other, for instance, then use the cursor keys to select a particular tile, tapping Enter to select it. Press the Windows key to return to the Metro screen; right-click (or swipe down on) apps you don't need and select Unpin to remove them; and drag and drop the other tiles around to organise them as you like.
