I want to step down through two slightly different versions of the same 
PDF document (two PDF slide shows, actually, either one of which may 
have a slide the other is lacking, or a new or updated version of a 
slide) so I can stop and correct differences where I encounter them; 
continue scrolling; then at the end delete one of them, keep the other 
as the master or archive version.

Any way to do this kind of simultaneous stepping in Acrobat, with both 
documents open in Window => Tile = Horizontally display, so that I can 
step both documents forward one page, without having to alternatively 
click and step in each window separately?  (Some text editors have a 
"synchronized scrolling" capability, which can be really handy for this 
kind of comparison.)

Can't do the underlying task in Pages view with lots of small icons 
shown in each window because I need a larger display of the slide in 
each window to see possible small differences.

Maybe an AppleScript that would step each document by one page?  

Or add some kind of action to every page in one document, that would 
simultaneously step the other?

Or a third one page "driver" PDF document that would step the other two?

(Unfortunately, I'm not skilled enough to try programming any of these 
ideas myself).

Why not just use the Compare Documents feature in Acrobat?

Searching under "Compare" in Acrobat 7.0 Standard help or Help Index 
brings up mention of ways to

* Compare PDF document to a web site from which it was created

* Compare signed document (after signing) to document before signing.

but no way to just compare two unsigned documents (and essentially zero 
info on just how either of these capabilities actually work).

Maybe the second one would be used, but given that I want to edit out 
the differences one by one as I step thru the two, I'm skeptical enough 
that I doubt I'l spend time trying.

I believe you need the "professional" version of Acrobat 6 or 7.
