onfullscreenchange DOM event <p>as the title reads, I'd like to know what is the most reliable way to trigger an event when the Browser(s) enters/leaves in/out the fullscreen mode.</p> <p><strong>note :</strong> I'm not asking how to fullscreen the current page, I just want to know whether or not there is a way to queue some tasks if the user, for example, press F11 or any other related fullscreen-entering keys.</p>
