It was totally by accident, but very useful.Give it a try and you might be surprised by the links it gives you.
Highlight a section of text in it's response and you see the options it gives you.
Choose 'Check Sources,' and it gives something I didn't see in the ones it cited originally.
Hope this proves useful; and I'll explain how to find the links to Youtube videos it cites, but doesn't give clickable links to, in a future post
Another lucky discovery
