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.
Examples
html
<button onclick="ismetaKey(event)">Click me with the meta key</button>
<p id="output"></p>
js
function ismetaKey(e) {
document.querySelector("#output").textContent =
`metaKey pressed? ${e.metaKey}`;
