NKRO

N-key rollover — the keyboard can register every key pressed simultaneously, with no ghosting.

Membrane keyboards typically support 2 or 6-key rollover: hold seven keys and one disappears. NKRO (n-key rollover) means every key registers, independently. Required for fast-paced games (WASD + space + crouch + reload at once). All mechanical gaming keyboards support NKRO; most office keyboards don't.
