Touching the Windows 8 Screen
A touchscreen, as the name says, enables you to touch the screen to tell your computer what to do. Not sure whether you have a touchscreen? When you have Windows 8 running, give the screen a poke with your index finger to see what happens.
The following terms refer to ways you interact with a touchscreen using your fingers or a stylus (pen):
Tap: Briefly touch the screen. You select an object, such as a button, by tapping it.
Drag: Touch and hold your finger on the screen, then move your finger across the screen. You move an object, such as an onscreen playing card, by dragging it.
Swipe: Touch and move your finger more quickly than with drag. You can swipe your finger across the screen from any of the four sides of the screen to display options and commands. You swipe pages to move forward or back. You may see the word flick instead of swipe. Some people insist that a flick is faster or shorter than a swipe, but let’s not get caught up in that.
Pinch and unpinch: Touch a finger and thumb or two fingers on the screen. Move your fingers closer to each other to pinch and spread them away from each other to unpinch. Generally, a pinch reduces the size of something on the screen or shows more content on the screen. An unpinch (an ugly word) zoomsin, increasing the size of something on-screen to show more detail.
