I don't know much at all about flash or action scripts but I was wondering if someone could help me.

In the UI.Get* function there is a "String Target" variable. I've seen a few examples of what to fill this with, but I was wondering how to find the target I am looking for.
Regarding the favorites menu, inventory, and magic menu. I'm mainly interested in the list of items and the current selection. You could just tell me the direct path but I really want to learn how to find it. I would like to learn how to edit and collect data from other parts of the menu in the future.

I know how to open up the swf's in a decompiler but I have no clue what I'm looking for.

Thanks in advance
