How to Synchronize Scrolling 2 Documents

[Paul5C04]

I would like to be able to open 2 documents side by side and synchronize the scrolling of both documents, so that if I hit page down for instance, both documents page down.  It doesn't seem like this is possible?

No, there's no built-in command in Acrobat that does that, but you can achieve something similar using a script, like this (paid-for) one I've created: https://www.try67.com/tool/acrobat-reader-synchronized-scrolling-two-or-more-pdf-documents

I use Acrobat's Compare feature.  

Go to Tools and Compare. It will produce a Compare Report with both documents side by side that you can scroll through simultaneously. You can filter out the change comments it leaves in case you just want to see the pages by themselves.
