  • The rate counts the moves this browser hands the page; browsers can join or drop moves, above about 1,000 a second especially, so it is what reached the page, not what the mouse sends.
  • Some mice handle their side buttons themselves, and then a page never sees them.
How it works and help
Everything happens in your browser. Nothing you press is sent anywhere or kept.

A little help along the way

Follow these steps. Every option is explained underneath. Everything happens in your browser; nothing you press is sent anywhere.

  1. Choose your keyboardThe shape (ANSI, ISO, JIS, ABNT2, Korean or Mac) is guessed from your system; change it if it is wrong, and choose the size: full, tenkeyless, 75%, 65%, 60% or the number pad.
  2. Click the board and press your keysEach key lights while held and keeps a tick once it has worked. The site's own shortcuts step aside while you test. Press Escape twice to leave.
  3. Hold several at onceTo test ghosting and rollover, hold many keys together; the result keeps the most held at once.
  4. Read the resultIt says how many keys have worked, which are still to press, the most held at once, and any key that bounced.

Questions people ask

Which mouse buttons can it test?
Left, right, middle (the wheel) and the two side buttons, back and forward, which are kept from leaving the page while you test. Some mice handle their side buttons themselves, and then no page sees them.
Can it measure my mouse's polling rate?
It counts the moves that reached the browser each second as you move the mouse in circles, which is close to the polling rate up to about 1,000. Browsers can join or drop moves above that, so it says what reached the page.
Does it work on a laptop's touchpad?
Clicks and the wheel work as the touchpad reports them; the test is made for a mouse, and taps on a touch screen are not counted as mouse buttons.
