HTC One M9 - Manual (Page 34)

Swipe or slide
Quickly swipe your finger horizontally across the screen to go to other
Home screen panels. Swipe vertically to scroll through a list, document,
and more.
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 right and left on the Home screen, or flicking through
a contacts or message list.
