How to Use Keyboard Tester

  1. Select Start keyboard test to focus the test area.
  2. Press and release a key. It fills while held and keeps an outline once tested.
  3. Hold a combination to check the Held count and highlighted keys.
  4. Press Tab to leave the area, or Escape to stop. Select Reset to clear the tested keys.

What you can check

What your result means

Latest key shows the character and the key's position code. They may differ on your keyboard layout. Held counts keys currently down; tested counts different key codes seen during the run.

Extra keys appear below the grid if their codes have no matching tile. A missing event does not always mean a broken key: the browser or system may handle a shortcut first.

Helpful tips

Keep focus in the test area while checking keys. Tab deliberately moves focus away so you can leave using the keyboard.

If an ordinary key fails repeatedly, compare it in another app. Check the connection, battery, layout, or remapping settings as needed.

Frequently asked questions

Why do some shortcuts not show up?

Your system or browser may handle them before this page receives a key event. That alone does not prove a faulty key.

Does the grid match every keyboard?

It shows common physical key positions. Your keyboard may have different labels or extra keys. The latest key display helps you compare layouts.

Can I test keys held together?

Yes. Hold the keys and watch the Held count. The page can only show events delivered by the keyboard and browser.

Does the page save what I type?

The page keeps tested key codes and the latest key in memory during the session. It does not build or upload a typed message.
