event.metaKey property

The event.metaKey property lets you know if the Cmd key was pressed during the event. If pressed, the property will return the value true, otherwise - false.

Syntax

event.metaKey;

Example

In the following example, when a button is clicked, we will display a message indicating whether the Cmd key or the Ctrl, Alt, Shift keys were pressed:

<button id="button">click me</button>

let button = document.querySelector('#button');

button.addEventListener('click', function(event) {
	if (event.metaKey) {
		alert('Cmd pressed');
	}
	
	if (event.ctrlKey) {
		alert('Ctrl pressed');
	}
	
	if (event.altKey) {
		alert('Alt pressed');
	}
	
	if (event.shiftKey) {
		alert('Shift pressed');
	}
