Apologies — I actually meant to say Keyboard API, not Fullscreen API.

...even then, nothing except Chrome-based browsers support that API. Not Firefox, not Safari, nadda. Even as a coder looking over that API I'm not seeing the benefit versus the existing keydown/keyup/keypress events?

The benefit is that using e.g. a Web-based IP-KVM solution over anything but Chromium is a pain, because an "Esc" closes your fullscreen view rather than being forwarded into the target system.

That's how the Fullscreen API is designed though? You're not meant to be able to over-ride that escape "get out of fullscreen" keystroke.

If anything Chrome allowing it to be over-ridden is the bug because I never, ever, want a website to be able to block me from leaving fullscreen mode with the same universal keypress. Otherwise what's the point of saying "press [ESC] to exit fullscreen" when the fullscreen API activates?

Most IP-KVMs I've used for years now don't bother fullscreen'ing for that reason, that API is meant mostly for games. For an IP-KVM (or any remote console really) generally the CSS 'object-fit: contain' is what most folks want, then there's no need to mess with either of those APIs then.

Chrome allows to use Esc to exit fullscreen by holding it. That's exactly what its UI says.

There's also Alt-Tab and other special key combinations that you would want to forward inside, not just Esc.
