FAQ — Keyboard Test Free Online Tool

What is the difference between key and code?

'key' is the character value (e.g., 'a', 'A', '1'). 'code' is the physical key position (e.g., 'KeyA') regardless of keyboard layout.

Why doesn't my media key show up?

Media keys (play/pause, volume) are often handled at the OS level and don't generate standard keyboard events. They may not appear in the tester.

Is this tool useful for game development?

Yes. Use it to understand which physical keys map to which key codes when implementing WASD or arrow key controls.
