Chip is a UI term (that widget is a chip, names styled as blocks in a To: field are chips, etc)

Is there a reason to use that though? From some quick Googling, I can't find any references to it. Also, there is already a term for a piece of a UI that you can click on to do something, one that doesn't have over a dozen other overloaded meanings (http://en.wiktionary.org/wiki/chip ), and one that users would be far more familiar with: "button".

Thanks! I've never heard that expression before. I'd be curious to know where it's usage comes from. It sounds like vague, new-school slang.

I was confused too, I think they mean "small button" - you can click the box that says Amazon.com (in their screenshot) to get the URL textbox.
