Thank you sir (@newageinv)! This was the "main event" post I was referring to last night, i.e. the User's Guide post was written in support of this one.

Very frustrating to learn I couldn't put bookmarks into these posts, but I will certainly remember for the next time.

There are over 10,000 words in these two posts. They could just as easily have been 12 - 15 posts, if there is no way to bookmark them.

Live and learn ...
