UI - scripting - pop up button value (I got it - nvrmynd)

How does one change this value:
I have —
tell application “TextEdit”
activate
tell application “System Events”
tell process “TextEdit”
delay 1
keystroke “S” using {command down, shift down}
click pop up button 1 of group 1 of group 1 of sheet 1 of window “text.txt”
– get value of pop up button 1 of group 1 of group 1 of sheet 1 of window “text.txt”
– I want to change value to “Unicode (UTF-16)”
end tell
end tell

Anybody have a script to outline the objects in a window, so we can figure out how to address object? FABUI (or whatever it is called) helps but stops right at the end.

I didn’t get the MENU 1 of pop up button —
