KeyboardEvent: metaKey property
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
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>Click me with the meta key</button>
<p id="output"></p>
js
document.querySelector("button").addEventListener("click", (e) => {
document.querySelector("#output").textContent =
`metaKey pressed? ${e.metaKey}`;
});
