key-ghosting

Check which keys are being pressed with this simple piece of JavaScript.

Open the keys.html file in your browser, ensure JavaScript is enabled and the cursor is in the input box, then press any keys and combinations of keys. The input box will show you which ones are registered.

Be careful when holding down the Control key, as this key in combination with other keys will probably activate some function of your browser.
