UI Browser Documentation

Is there any documentation for the UI Browser 4.0 app? I was hoping there’d be some write up on it somewhere as I can’t get it to do anything. When I select Mail.app from the target menu, I do see root and application columns, but I don’t know where to go from there. Clicking the Activate button brings Mail to the fore, but nothing else happens.

How do you get it to generate AppleScript? Every command in the AppleScript menu is grayed out.

Thanks a million!

Apparently, I downloaded the wrong version:

UI Browser 4 is an UNFINISHED WORK and is not fully usable in its current form.

Version 3 works fine on Ventura.
