To use it, do a Find and make sure it is finding what you want. The macro will use the Find you just executed and find all occurences and show them in red. It will also grab section and page numbers. You will need to revise that to fit your own setup.
Word macros are slow since they are written in Basic.
But if you run a search and go make a cup of coffee, it will probably be waiting for you when you come back. This was originally done in the Chinese edition of Word for two-byte Chinese characters. I revised it for English but there are still Chinese characters in the macro. You will probably have to do a bit of adjusting if you are not using Chinese Word to make the macro suit your version of Word. If anyone has any suggestions for improvement, please let me know.
