Windows 8 supports a whole host of touch-screen gestures, including the swiping, pinching and rotating motions familiar to smartphone and tablet users. Tapping an item opens it; pressing and holding an item pops up a menu to display more information about it. Note, however, that these gestures often don't work in Desktop apps. (See "Meet the Start screen" for the differences between Desktop apps and Windows 8 apps.)
Windows 8 also uses something called edge UIs, in which you swipe from the edge of the screen toward the center. Swiping in from the right edge of the screen displays the Charms bar. Swiping quickly in and back out from the left edge of the screen cycles through your open apps.
While the previous edge UI gestures work universally, some are specific to Windows 8 apps. When you're in a Windows 8 app, swiping up from the bottom of the screen or swiping down from the top of the screen displays the App bar (more on that in a moment). And you can close a Windows 8 app by pulling down from the top edge of the screen all the way to the bottom of the screen. The app shrinks to a thumbnail and then disappears.
Following is a list of useful Windows 8 gestures, including more edge UI gestures. Keep in mind that not all of the following gestures work in all places and apps. Typically, they don't work in Desktop apps.
