How can I combine load() with lightbox??

How can I combine load() with lightbox??

Hi - I'm not a jQuery (or any other kind of) programmer so I appreciate expert's input.   I've been experimenting while learning javascript and I'd like to know how to do a "trick" that combines 2 things I've seen done with jQuery.

I've seen how beautifully lightbox makes a photo appear and makes the screen behind it darken.
I've seen how a jQuery/AJAX (?) method or action (load?) can make clicking a link in one html page bring in a div from an external html page.
I'd like to combine these two so that clicking a link on an html page brings in code from an external html source and displays it with the smooth animation and highlighting/screen darkening of a lightbox show.

I don't think this qualifies as a "popup window" - which is NOT what I'm looking for (I think everyone blocks popup windows).

I hope I have explained this accurately enough. Thanks in advance for your expertise in figuring out how to create this effect.
