Shadowbox <a> link to target parent window?

I'm a n00b when it comes to JavaScript and the DOM... once I've opened up an HTML file in a shadowbox, how do I make 开发者_运维百科an a href link or submit a form from the shadowbox into the parent window? I'm using Rails to build my forms, not sure if that makes a difference.

I'm assuming shadowbox is an IFrame powered dialog box system. In that case,

target="_parent" or target="_top"

should work.
