To close a modal popup with the ESC key, you can add a JavaScript event listener to the document that listens for the `keydown` event. When this event occurs, check if the key pressed is the ESC key (key code 27). If so, execute the code to close the modal. Here’s a quick example: `document.addEventListener('keydown', function(event) { if(event.keyCode === 27) { // Code to close modal goes here } });` This solution enables user-friendly navigation by allowing modals to be easily dismissed with a keystroke.
