Keyboard Layout Tester
Press any key to test it. See its name, code, location and modifiers, watch it light up on the visual keyboard, detect whether your layout is QWERTY, AZERTY or QWERTZ, and try the sticky keys test mode. Tip: click anywhere on this page first so your key presses are captured here.

Sticky keys test mode
When on, a modifier like Shift stays latched for 4 seconds after you release it. Then press a letter and the tester registers it as a sticky combination (for example Shift + A) without you holding both keys. Press the modifier again to unlatch it.

How to test your keyboard
- Click anywhere on this page, then press keys one by one.
- Read each key name, physical code and location in the panel above.
- Press Q, W, A, Z, Y, M to let the tester detect your layout (QWERTY, AZERTY or QWERTZ).
- Turn on sticky keys test mode and press Shift, release it, then press a letter to simulate a sticky combination.
Everything runs in your browser — nothing you type is sent anywhere. The numeric key code shown comes from the classic keyCode value for reference; the physical code (for example KeyA) identifies the key position regardless of your layout.
