How to Use the Keyboard Tester
- Press Keys: Simply type on your physical keyboard. The corresponding key on the screen will light up Blue (active) and then Green (tested).
- Numpad Support: Use the right-side number pad to test 0-9, arithmetic keys, and Enter. (Ensure NumLock is ON).
- Check for Ghosting: Try pressing multiple keys at once (e.g., W+A+S+D). If a key doesn't light up while others are held, your keyboard may have ghosting limitations.
