Keyboard Tester
The browser cannot see every key. The Fn key, volume and media keys, and shortcuts the operating system keeps for itself (such as the Windows key or Ctrl+W) may not show up. If one of those keys works for you elsewhere, double-click it to mark it as working.

About this tool
Test every key of a new or old keyboard. Press a key and it lights up on the on-screen layout; keys that work turn green. The tester also spots keys that register twice, shows how many keys your keyboard can send at once, and counts your typing speed. Everything is calculated in your browser, so nothing you type leaves your computer.
