HTC One E8 - Manual (Page 31)

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.
Press and flick
On the Home screen, you can easily move a widget or icon from
one screen to another.
Press and hold the widget or icon with one finger, and flick the
screen to the new location with another finger.
Slide with two fingers
In some apps, like Gallery, Messages, Mail, or
the web browser, slide two fingers apart to zoom
in when viewing a picture or text.
