"Thanks for all this help. I will keep working and learning. What an amazing program you guys have here! I wonder what your cooking up for SA 6? :-)
I'll see if I can take what you have offered here and try to cut down on my questions now. Thanks…"

"I was actually looking at individual presets, not PASeq. I should have made that clearer. Just trying to figure out what, if anything I need to worry about in there. Apparentl;y, as you say, they have to do with scipts so in the individual preset…"

"9) Sorry. Another question. For the PAS  Dogs and Cats on Chipped Paint, I do not see how to change the image?. I looked in the editor, bit nothing seems to fit."

"8) Last question. The Mosaic Tiling and Half Tone section seems super cool. Any advice/examples/links  on how to artfully combine those basic effects with other Presets elsewhere in SA?

"5) Continuing...for the preset "Text Banded" under Mosaic, how do I change the text that is displayed? I don't see where the text comes from in the preset. "

"That would be wonderful. Most graphic programs I have used just have you click and do - there is no click, save step, edit step, then do. 
Thank you again for the excellent help, and you patience.
Gary"

"P.S. I just re-read all you wrote an now it makes sense to me. Thanks again."

"Next morning.....
Here is what I wrote to Sean in the related ticket for this:
Hi Sean,
That helped, thanks. My basic problem was that I didn't realize you had to save out and then edit your presets. I assumed they would just work out of the box.
I…"

"Thank you again. I am going to look at all this in the morning and see if I can make sense of it. 
Gary"

"OK. Wow. I admit, I am overwhelemed. The terms which you use so freely as you mentally fly about the program in your mind as a Dev are all new to me, so when you connect the dots in your mind it all flows, but the same does not go for someone new to…"
