Frequently Asked Questions
How do I know if a key on my keyboard is broken?
Press each key one at a time and watch the on-screen keyboard. If a key does not highlight or register when pressed, it may be stuck, damaged, or disconnected. Try cleaning the key or testing with a different keyboard to confirm.
Does this keyboard test work with mechanical keyboards?
Yes, this test works with all keyboard types including mechanical, membrane, laptop, and wireless keyboards. It detects standard key codes sent by any keyboard connected to your computer.
Why are some keys not being detected?
Some keys like Fn, media keys, or special function keys may not be detected because they are handled by your operating system or keyboard firmware rather than the browser. Also, certain key combinations may be intercepted by your OS.
Can I test keyboard ghosting and rollover with this tool?
Yes, try pressing multiple keys simultaneously. If some keys fail to register when others are held down, your keyboard may have ghosting issues. Mechanical keyboards with N-key rollover should register all keys pressed at once.
