How to read the results
- Green: the key you are pressing now. If it lights up the moment you press it, the input is reaching the browser.
- Blue: a key that has responded at least once. Press every key in turn to find the ones that are still unchecked.
- White: not checked yet, or a key the browser cannot read.
