hudkit doesn't seem to recognize when buttons are pressed on the keyboard. Here's a simple test page that should be displaying the keycodes.

<html>
<head></head>
<style>
body {
	background-color: #000;
	font-size: 30px;
	font-weight: bold;
	color: #fff;
}
</style>
<body>
<p id='keyCode'></p>
<script>
document.addEventListener('keydown', function(e) {
	document.getElementById("keyCode").innerHTML = e.keyCode;
});
</script>
</body>
</html>

I'd love this too, but I haven't been able to figure out how to make it work.

As it stands, if I make the window able to be focused (by commenting this line and these lines), input events are sent to the webview, but it eats them, and they don't propagate to the desktop, so the window isn't click-through anymore.

I figure it must be possible somehow to hack around with GTK's event propagation functions to do this. Duplicate the event, propagate one to the webview, and the other to the desktop? Maybe. 🤔

Workaround: xkbcat into a WebSocket.

Grab keyboard focus when clickable area hovered

Finally figured out how to do this.  This change makes it possible for
the first time for the overlay window to react to keyboard events, and
so it's possible to make any arbitrary interactive web UI with it!

It's pretty neato.

This is a proof of concept!  There are many minor bugs, like
drag-and-drop completely breaks when trying to drag out of the overlay's
clickable area, and enter/leave events jitter when sweeping the mouse
along edges of the screen.  That kind of thing.

Related to #3 and #5, but not global; no events are duplicated here.
