A keyboard test with a Mac layout
This is an independent tool. It is not affiliated with or endorsed by Apple. The layout simply follows the labels you find on a Mac-style keyboard, so you can match each key on screen without translating from a Windows layout.
Press Start testing and press each key in turn. Keys light up while held and turn green once they have worked. The counter shows how many you have tested so far, and Reset clears the board.
The keys that differ from a PC keyboard
| On this test | Where it sits | Windows-style name |
|---|---|---|
| Control | Outer ends of the bottom row | Ctrl |
| Option | Between Control and Command | Alt |
| Command | Either side of the Space bar | Windows key |
| Delete | End of the number row | Backspace |
| Return | End of the A row | Enter |
The browser reports keys by position, which is why Command lights up from the same key code a Windows key would send. Above the main keys you get the function row from F1 to F12. There is no number pad and no navigation block, only the main keys and the arrows.
Testing Command, Option and Control
Modifier keys are easy to skip, so press the left and right Command, Option and Control keys one at a time. Each side counts as its own key on the counter.
Some shortcuts that use these keys are handled by the operating system and may never reach the browser. Press the modifiers on their own rather than in combination with letters and you will get a cleaner result. If a single key stays grey but still does its normal job outside the browser, it is working.
If a key does not respond
Clean around the key and try again. If you use an external keyboard, unplug it and try another port, or reconnect it if it is wireless. If the wrong character appears in the Last key field, check that the keyboard layout chosen in your system settings matches the keyboard in front of you.
When every key is green, put the keyboard to work on the typing test. For a Windows-style layout with a number pad and navigation keys, use the keyboard test.
