I just posted a quick and dirty tutorial video for how to use UI Browser with Keyboard Maestro.
It's not nearly up to my normal standards, but I knew if I didn't just get it done, I'd never do it. Sorry about so much zooming and panning. And the audio quality - I just used my iMac mic, not my pro mic.
Regardless of the quality, I hope this shows that even if all this UI Browser stuff is Greek to you, you don't actually have to understand much of it to make use of it. Just follow the steps.
So if you want an introduction to UI Browser, so you can do things like checking to see if a checkbox is checked, or "checking" a checkbox, or how to tell if a UI field is enabled or disabled, this ought to help.
Feel free to ask questions. If you feel like you have to offer critiques or ways to improve the video, I'm willing to bet I already know them all. Like I said, this was a "fly by the seat of my pants" thing, and I really do know how to do better.
Have I given enough excuses yet?
