Unable to figure out icons for paper-fab

[Paul Lewis]

I grabbed the <paper-fab>, and then I wanted an icon. It complained I didn't have the iron icons in the console (ace, love it), so I imported those. But then I couldn't find out which icons are in the iron set (vs any other set), so I went to https://elements.polymer-project.org/elements/iron-icons and that has no documentation.

Feels like we should have a list of icons, and where they come from.

Yep. We're missing a few bits here. iron-icons actually has a demo that shows all the icons, but it's not getting linked up:
