Thanks for the both of you for your input!
What I am attempting to do is expand all of the triangles in an index with as few clicks as possible.
This way when I am searching for, let's say, a scripture in a Systematic Theology, here is what I do.
I set my, "Show Text As" - "Add Titles" (the little gear next to the "A A" in the upper right-hand corner of the window)
As I scroll through my search results the index automatically highlights where this is found in the index. This would save time by not having to "drill down" in the index, to see where every search results found.
On a related note, when I hit Control click, on a triangle in the index, I come up with a menu that says;
Add To Range
Maybe my answer lies in this menu, However, I can't seem to find help in the help system about this.
Hopefully this makes sense to you, it just seems to be the way my brain works (or doesn't work):-).
Thanks for your consideration!
