The KeyboardEvent.metaKey read-only property returning a Boolean 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. On Windows keyboards, this is the Windows key (⊞ Windows).
At least as of Firefox 48, the ⊞ Windows key is not considered the "Meta" key. KeyboardEvent.metaKey is false when the ⊞ Windows is pressed.

A boolean
