How do I check a backpack.tf classified threw Scrap.tf.

[Larry]

I just started trading for something fun to do and I am confused, I was watching a video on trading and the dude was able to check an items classified list threw Scrap.tf. here's the link. He first does it at 15:38, But I don't know how he did that. Sorry if this is really easy to do I am just really new to trading. If anyone could tell me how to do it that would be really appreciated. :)

That seems to be a browser extension, the site doesn't normally give you those options. So maybe you could try looking for that extension
