You cant focus on canvas if there's no tabindex on it , am I right?

 

<canvas tabIndex=1> </canvas>

 

renderer.view.setAttribute("tabIndex", 1); 

 

also its good to check if canvas is focused, and if not then draw "CLICK TO FOCUS" label in the middle of it, like https://ga.me does it.

I solved the problem using this method

	this.renderer.view.setAttribute("id", "worldCanvas");        $("#world").html(this.renderer.view);         var lastDownTarget, canvas;		canvas = document.getElementById('worldCanvas');		lastDownTarget = canvas;		document.addEventListener('mousedown', function(event) {			lastDownTarget = event.target;		}, false);			document.addEventListener('keydown', function(event) {			if(lastDownTarget == canvas) {                                event.preventDefault();                                event.stopPropagation();				wi.doKeyDown(event);			}		}, false);

Holding a variable just to check focus sounds like a terrible idea, the `tabindex` method would surely be more intuitive (although still a hack, but, whats a hack between friends anyway?)? I've thrown it into a plunk and it works fine, I havent checked browser compatibility but I'd imagine it works everywhere (I'd say that mobile could cause a problem, but you're not using keyboard interface there anyways, actually, given new tablets this could be viable, particularly in the near future).
