What this checks
Some keyboards cannot register certain groups of keys together. This can affect gaming movement, shortcuts and fast multi-key input.

Browser input passes through the operating system and hardware stack. This tool is excellent for practical checks, but exact hardware-level rollover classification depends on the keyboard controller and firmware.
