Hey Ali,
No bets...
Try running my window analysis tool:
Window Analysis Tool for System Events v1.50
It will bring up everything System Events can see about the front window in TextEdit, or TextWrangler, or BBEdit (whatever is on your system).
Then you can use “find” to search for your desired item.
If you can find it in the text then it's possible it can be used in a gui script.
