d-pad

Jargon.

A cross-shaped digital pad used for directional input on a controller. Popularized by the Nintendo Entertainment System (NES) controller. Short for directional pad or digital pad; d-pad acceptable on all references. Do not capitalize the "d" unless at the beginning of a sentence.

Don’t use any punctuation when referring to specific directions on the d-pad. The quicker you tap left on the d-pad, the faster your character will go.

Example: The Nintendo GameCube controller has a very small d-pad.

Wrong: cross, control pad, digital pad, D-pad, D-PAD, pad.
