What is the Keyboard Tester?
Check whether every key on your laptop or external keyboard works. Press keys and they light up on the on-screen keyboard; the tool shows the key name, code and keyCode, counts tested keys and highlights keys that are held down – useful for finding stuck keys and ghosting on gaming keyboards.
Great before buying a used laptop or after spilling something on your keyboard.
