n-key rollover

N-key rollover (NKRO) is a keyboard feature that allows each keypress to be registered independently, regardless of how many other keys are pressed simultaneously. This is especially important for gaming and fast typing, where multiple keys may be pressed at once. On WindowsForum.com, discussions about n-key rollover often appear in the context of gaming laptops and high-performance keyboards, such as the Razer Blade 15 with optical switches. Users seek advice on which keyboards support NKRO and how to enable it in Windows. The feature is commonly found in mechanical and optical gaming keyboards, ensuring that every keypress is accurately detected without ghosting or blocking.
