Greek, Hebrew and Aramaic I can do, but what is this?

I want to create a new Copy Bible Verses style. But how? In L3 it was straightforward. But how to begin here?
What are all those punctuation marks? What do they mean? Is this a kind of programming language? If so this is very user-unfriendly for the the non computer-literate among us. I understand that to some people this will be easy, but to me this is weird (and I've been using computers and software for 30 years this summer).
All I want to do is tweak, as I did in L3, some quotation styles to suit my sermon mind-maps and academic papers.
Can somebody help me here? Acts 8:30-31
