Word's VBA 'sentence' definition has no idea what a grammatical sentence is, therefore you can't use:
Selection.MoveRight Unit:=wdSentence, Count:=1


reliably to get the next grammatical sentence. The problem with trying to build a set of exclusions of the kind you envisage is that there is no end to the number of possible exceptions once you start trying to cope with every kind of abbreviation & acronym while at the same time handling the fact it's possible a grammatical sentence might actually end with such an abbreviation or acronym. Plus, sentences don't always end with periods...

And no, the "With Selection.Find" function isn't the only one; neither would it be my first choice.

What would be your first choice (as opposed to the "With Selection.Find" function) to moving the insertion point based on surrounding text?

I certainly understand sentences don't always end in a period. That's why I said I want to keep the definition of a sentence for this macro as the distance from the insertion point to the next (1) period plus a space or (2) Paragraph sign.

I don't want to give up yet just because there are other possible acronyms either. The three I mentioned are really the only ones that I encounter in my reading.
