D-Pad
Direction Pad
A typical D-pad is a set of four buttons arranged in a circle or diamond that function as "arrow" keys, allowing the user to move up, down, left, and right within the device's user interface, such as scrolling through menus.
Many D-pads also have a button in the center that performs a "select" or "OK" function.
The surface of the four keys may be physically separate, or joined into one ring. Similarly, the center key may be separate, or joined with the rest of the D-pad, in which case the center-select function may require pressing down on the entire D-pad.
