FAQ
What does this keyboard tester do?
It displays a virtual QWERTY keyboard and highlights each key you press in real time. It also shows the keyCode, key name, and event code for every key press.
What is anti-ghosting?
Anti-ghosting means the keyboard can register multiple simultaneous key presses. This tester highlights all keys pressed at the same time so you can verify your keyboard supports it.
Does it work with non-US keyboard layouts?
The virtual layout shown is US QWERTY. Your physical key presses will still be detected and displayed, but the visual mapping may differ for non-US layouts.
Can I use this to test if a key is broken?
Yes. Press every key on your keyboard. If a key does not highlight on the virtual keyboard, it may be malfunctioning.
