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
