Coping with Windows 8 Start: Type-to-search
It may look like it has vanished, but type-to-search remains another useful way to avoid getting hung up on the Windows 8 Start screen. Type-to-search behaves roughly the same way as it does in Windows Vista and Windows 7: Begin typing, and you see results. (You do need a physical keyboard, so this technique won't work on a tablet with just an onscreen keyboard. Instead, open the Search charm by swiping from the right edge of the screen.) Note that the context of the search is determined by the highlighted item directly below the search box.
