Frequently Asked Questions
What does the keyboard tester do?
It highlights keys as you press them and shows key codes to confirm that every key works.
Why do some keys not light up?
Some laptop keyboards map Fn/Media keys differently. Use the physical key codes shown to verify mapping.
Does it collect my keystrokes?
No, everything runs locally in your browser. Nothing is sent to a server.
