I'm trying to write a macro that will toggle the tracking without changing the current setting of the revision display. Why is the following code not working? It turns on the mark-up display when the tracking is turned on too. What I want to achieve is just to turn on tracking without disturbing the current revision display setting.

The probable reason your code doesn't work is that it:
a) captures the current setting,
b) turns on track changes,
c) restores the original setting.
So, unless track changes was already 'on' when you started the macro, it would be 'off' again once the macro has finished running. All you need is:
ActiveDocument.TrackRevisions = True
which hardly seems worth a macro - you can achieve the same result by adding the 'track changes' option to the status bar, then clicking on that any time you want to change the state.

But your suggestion doesn't achieve what I want to achieve besides turning on/off tracking: I want to keep the current revision display setting. If revision display is off, it shouldn't be turned on by switching on/off the tracking; if revision display is on, it shouldn't be turned off by switching on/off the tracking.

The track change option will turn on the revision display as it turns on the tracking.

Well you have to decide whether you want the tracking to show. Your code simply retains whatever the existing setting is and can therefore be reduced to one line; merely turning on track changes doesn't change whether they're displayed. If, however, you want to turn on track changes without displaying them, you need something like:

I think you and I may be using different versions of Word. I'm on Word 2003.
With Word 2003, turning on the tracking will turn on the tracking display too. Give it a try. Turn off both the revision display and the tracking. Now turn on just the tracking (ctrl + shift + e by default). You'll notice that the revision display will come on together. I want to prevent that.

OK, with my testing on Word 2003, both your original macro and the one from my last post allow change tracking to be turned on without showing the markup. The only difference is that mine explicitly turns it off whereas yours retains whatever the entry state was, which might already have been one of the markup views.

That is strange.. So, my macro actually performs what I intended on your system, while it doesn't on my system. Let me look into it. Thanks for the info.
