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.
var metaKeyPressed = instanceOfKeyboardEvent.metaKey
A boolean
function ismetaKey(e) { alert("metaKey = " + e.metaKey); }
<button onclick="ismetaKey(event)">Click me with the meta key</button>
