Keyboard test
Press every key and watch it light up on the on-screen keyboard — find dead keys, check key codes and how many keys work at once. Free, in the browser.
Press every key — each one lights up when the keyboard sends it.

A key that never lights up is not reaching the computer — dirt, a worn switch, or a keyboard fault. Hold several keys together to check rollover: most keyboards register 6 or more at once; gaming keyboards, all of them. 0 presses so far.
