HTC 8X - Manual (Page 18)

Drag
Press and hold your finger with some pressure before you start
to drag. While dragging, don't release your finger until you
have reached the target position.
Flick
Flicking the screen is similar to swiping, except that
you need to swipe your finger in light, quicker
strokes, such as when moving from the Start screen
to the apps list.
Pinch and spread
In some apps, such as Photos or Internet
Explorer, spread your fingers on the
screen to zoom in when viewing a picture
or text.
