How to test your keyboard
With this page open, press the keys on your keyboard one at a time. Every working key turns blue while it’s held down and green once it’s been tested.
If you press a key and nothing lights up, it may be broken, disconnected or have crumbs and dust stuck underneath.
Right below, you’ll see the name of the last key you pressed and its technical code, which comes in handy when setting up games and apps.
Frequently asked questions
Does it work with a laptop keyboard?
It works with any keyboard: laptop, USB or wireless. A few special keys, like Fn, are never sent to the browser.
Why do some keys close the page or change the zoom?
System shortcuts like Alt+F4 or Ctrl and + are handled by your computer before the browser sees them. Avoid key combos during the test.
