Apple keyboards use familiar key events but label several modifiers differently from Windows keyboards. This Mac keyboard tester displays Command, Option and Control so the visual layout is easier to compare with a MacBook or Apple external keyboard.

macOS and the browser reserve some shortcuts, so certain combinations may trigger a system action instead of remaining on the page. A single shortcut behaving differently does not necessarily mean the physical key is defective.

FAQ

Frequently asked questions

Can I use this on a MacBook keyboard?+

Yes. It works with built-in MacBook keyboards as well as Apple and third-party external keyboards.

Can the website detect the Command key?+

Yes, Command normally appears as MetaLeft or MetaRight in browser keyboard events.

Why is the Fn/Globe key different?+

Apple may handle the Fn or Globe key at the system level, so it does not always produce a standard event that webpages can detect.
