I have limited experience with the Compare function/method and have never done it using VBA.

I'm not sure it would work well with what I'm trying to achieve. Imagine a Master Document that contains 30 or 40 chapters that is assembled with the use of Selection.InsertFile for each chapter (30-40 separate documents that represent a chapter). Each insertion is a new section in the Master.

The first issue, I believe, would be the fact that I would have to open the Chapter document to conduct the comparison. That brings some performance issues, not that I'm looking for lightning fast performance.

The second issue is that I'm comparing a Master document of 30-40 Chapters with a single Chapter, so I don't know that this would be manageable unless I could compare the Chapter document to a selection in the Master. Is that even possible - comparing text selections, ranges, or sections in two different documents (as opposed to the entirety of each document)?

Additionally, the comparison probably would have to be done between the Chapter template and the User's modified version of the Chapter, then inserted into the Master. I kind of want to track it inside the Master, but I'm not sure that's necessary.
