Recreate "change tracking"?

[Andrew25899629o8zx]

If I forgot to enable change tracking before beginning to make edits (75-page document containing text and images), can I retroactively generate the "change tracking" information using some sort of "Document compare" feature (as in MS Word)?  In other words, compare the current version of the InDesign "document" with the original?

To see where you have "custom tracking/kerning" go to Preferences > Composition and check Composition > Custom Tracking/Kerning.

Text which has this applied will appear with blue-green highlighting:

I think the OP is referring to track changes and the answer to the question is no, there's no straightforward way to do this. I suppose PDFs of both documents could be compared but even that isn't going help anyone go back in time and turn on track changes.

Interesting, since I never use Track Changes, it didn't even occur to me. I could only think of manually changing tracking. You may be right.

Thanks, Bob.  I think I have to rely on PDF comparison for past changes, and on (enabled) change tracking for changes going forward.
