From Pop-up window to calling page.

I have a page(let's call it: main browser) that links to a pop-up window(popup). The pop-up window has an i-frame (iframe).

In the i-frame window (iframe), How do I open links up in the calling window(main)? Is there a way to reference browser windows before calling them?

Target="_blank" opens up in a new window and Target="_parent" both open up in the same browser.



Any help would be greatly appreciated!
