KeyboardEvent: metaKey property

The KeyboardEvent.metaKey read-only property returning a boolean value that indicates if the Meta key was pressed (true) or not (false) when the event occurred. Some operating systems may intercept the key so it is never detected.

Note: On Macintosh keyboards, this is the ⌘ Command key.

Note: Before Firefox 118, the ⊞ Windows key was handled as an "OS" key rather than the "Meta" key. KeyboardEvent.metaKey was false when the ⊞ Windows key was pressed.

Value

A boolean value.
