Close Window Button

[GravityStorm]

How can I make a button that closes the window after a visitor adds an item to their cart? I'm using a digital catalog on another site, and I want to link to specific items in my Zen db -> add them to the cart -> and close the window ( closing the zen window will automatically return them to the digital catalog, because it is still open behind the zen window) -> they can then check-out (in ZC) when ever they are ready.
I also need the direct "url" to the "check-out" page, so I can put a link to that in the catalog.

You're asking for sessions problems if you want to have your customers switch back and forth between Zencart and non-Zencart pages.

I've tested it by X-ing out the window, and it seems to work great. (As long as you're on the same computer and you don't wait too long). A "Return to Catalog" button (closing the window) would be much more intuitive than having them x-out the window.
