vba control of shading

macropod:

I finally had a chance to thoroughly test your code (after being distracted for a month) and found that it listed 19 shaded regions, just as you said. However, there are 27 shaded regions in the test.docx I posted in this thread.

I learned a lot from your code, but I still don't understand Word VBA enough to figure out what was wrong. So, instead I modified your code in a way I could understand. You'll see that your code is still there, but commented out. This modified code gets all 27 shaded regions, but I found that preceding superscripts would cause a 1-character shift in the highlighted range. I added an if statement to fix this (but I really don't understand it). Oh, and I also commented out a part of your code at the bottom that didn't seem to apply -- I think it has to do with tables?

I'm sure my code could be improved. If you have any more pointers I'd be glad to hear.

Thanks again

Code:
