Capturing ctrl+z key combination in javascript
I am trying to capture ctrl+z key combination in javascript with this code:

<p>For future folks who stumble upon this question, here’s a better method to get the job done:</p>
<pre><code>document.addEventListener('keydown', function(event) {
if (event.ctrlKey && event.key === 'z') {
alert('Undo!');
}
});
</code></pre>
<p>Using event.key greatly simplifies the code, removing hardcoded constants. It has support for IE 9+.</p>
<p>Additionally, using document.addEventListener means you won’t clobber other listeners to the same event.</p>
<p>Finally, there is no reason to use window.event. It’s actively discouraged and can result in fragile code.</p>
