The best scenario to describe this question is, if you go to the advanced editing window and click on "more", a popup will come up, and you can click on the smilies in the popup and it inserts them into the text field in the original window. How can I make mt own version of something like that?

Every browser I've used so far gives me the ability to view the source. You should be able to see all the javascript used.

you would use parent.element.property to control the main window
