Keyboard Tester

Press every key to light it up on a virtual keyboard and spot dead or stuck keys, with key code details for developers.

Click anywhere on this page, then press keys — each detected key lights up. Useful for finding dead or stuck keys.

Note: some browser/OS shortcuts (e.g. F11, Cmd/Win combos) may be intercepted before reaching the page. Tested keys stay highlighted so you can sweep the whole keyboard.
