If you have, say, 10 separate docs with tracked changes, it would be handy to
combine into one doc, where the result is that, where there is no change to
the text, it just shows up once in the correct place, and then when you come
to a change, it shows up in a unique color for each author, and if 2+ authors
changed the language differently, each change would show up sequentially at
the same place in the document.

Not sure if I explained this well, but the concept is more of a 10 document
merge rather than insert or copy and paste as some MVPs have suggested.
Insert or copy and paste seems to connote that, for example, if the document
is 1 page and you insert each of the 10 versions, you end up with roughly an
11 page doc with sequential duplication and no easy way of evaluating changes
in one place.

With what I'm suggesting, a "merge", you end up with, say, a 1.5 page doc
where the unchanged parts just show up once and the changed parts are all
grouped together around the parts changed, with different colored tracked
changes showing each author's changes.

This would make managing multiple changed docs much easier. You could
accept/reject without having to copy and paste manually from multiple
documents.

Is this, or something similar (not Insert as you suggest below) available
under Word 2003? Do you know of any macros or third party programs which
facilitate this?

Another question: In earlier versions of Word, you could accept/reject a
change and the program would automatically move you to the next change. In
2003, it seems to be a 2 step process requiring 2 clicks where 1 click did it
in earlier versions. Is there any way to make this happen in 2003? Detailed
instructions would be appreciated.
