What exactly does this jQuery selector do?

I have been studying a piece of jQuery script and editing it for my needs for a few days now. It contains the following lines.

var newElement = $("#featured-post").clone();
var inputField = $("select", newElement);

I just don't understand what exactly the second line does as I haven't seen such a selector before (yes, I'm new to jQuery).

I can guess that it selects "" elements within the cloned element. But I have not read about this method of selection before. Could somebody explain a little bit about this selector? I've done some googling but didn't find anything related to this. Thanks a lot.

To make it simple for you, the below code:

$("select", newElement);

is same as doing:

$(newElement).find("select");

So, the selector will look for the select element inside the newElement cloned element.
