Yes, the Raise has NKRO or N-Key RollOver.
N-Key RollOver means that if you simultaneously press multiple keys or all keys on the Raise, they will all be registered.
NKRO also prevents "ghosting", which happens when a single keystroke or several keystrokes are "lost" due to the inability of a keyboard to process simultaneous signals.
In gaming, gamers often press several keys at once while playing, so it is essential for the keyboard to register all the input accurately.
