Hmm, I was afraid of that. Guess I'll make do with the macros I'm using now and just toggle them on and off. Thanks for the response, though.

If you create a couple of character styles – I use a cheery light green for New and a discreet grey strike-through for Deleted – you can tag your own changes with these rather than using the Track changes mechanism. I'd suspect you can then use search/replace to skip from one of your changes to the next.

Added bonus, thinking back to the first time I shared a Tracked changes document here – your fellow reviewers will see your changes in relaxing green/grey rather than everything in shrieking red. Easier for them.
