Help with Snap! Snap! Community Site

So I'm trying to use some JavaScript to focus an HTML element on the community site. Here is the JavaScript im gunna use:

HTMLElementObject.focus()

I would use "Inspect Element" to find the HTML element on the community site, but I cant because my laptop wont allow me. That is why I have created this topic. Please help!

world.children[0].stage.focus()

?
The stage isn't an HTML element afaik, though.

I was told it is an I frame.

the stage isn't an html element, but the project player is an iframe. My only question is, how does the focus element work? does it look for element id?
