I wanted to get the URL for a location in the iTunes music store. I got through an email link and forgot that the UR would be there, so I tried different combinations of keys and found that Command-Option and dragging the button in the little breadcrumb/navbar area got me this.
Drag the selection to the desktop or wherever. You end up with a webloc file that will open iTunes to the page specified.
Usually, you can just option-click an album cover or name and get URL but that doesn’t work on this navbar items.
