Script for automation of actions needed

Hello, I need someone to create a script for me, for example an autohotkey script, that will perform a series of actions when I activate it. To be exact, I want to do the following: I have two Word documents open, side by side, both have track changes in them. I want to press a button, let's say for example, "Page down" and do the following: Go to the left open document > click "Next Change" > shift to the right open document > click "Next change". The point of this is that I want to have both documents open, side-by-side, and be able to move consecutively from one track change in the left Word file to the next track change in the right Word file. My daily job is to compare track changes between files, so I need to do that hundreds of times a day. Go to left open Word, click Next change, go to right open Word, click Next change. So, to sum up: Two open Word documents, both on the screen. I want to be able with one button/keyboard shortcut/anything, to move from the left document > to the next track change > to the right document > to the next track change. Important note: BOTH documents need to be open on the screen at the same time. No minimizing of one document to go to the other, no overlapping of documents. Both need to be side by side at all times. See the attached photo as an example. Thanks!
