KeyboardEvent metaKey property

DOM events KeyboardEvent

Definition and usage

The metaKey property returns a boolean value indicating whether the "META" key was pressed during the key mouse event.

Not all keyboards have a meta key. For Sun Microsystems keyboards and MIT and LISP machine keyboards, it is common. The meta key is marked as "META" or marked with a solid diamond symbol "◆".

On Mac keyboards, the META key is represented by the "Command/Cmd" ("⌘") key.

Note:This property is read-only.

Example

Determine if the "META" key was pressed when the keyboard key was pressed:

var x = document.getElementById("demo");
if (event.metaKey) {
  x.innerHTML = "The META key was pressed!";
}
  x.innerHTML = "The META key was NOT pressed!";
}
