Ran across these extremely helpful Microsoft Word tips by romance author Monica Burns. Monica instructs you how to create a macro for repetitive words. I did this yesterday and it wasn't hard. The macro then searches for a word you specify and highlights its usage. It can be quite sobering to scroll through a document and see such passive words as saw, heard and felt highlighted again and again. There's also a macro to reverse the highlights, so be sure to install that one too.
Monica also has instructions for making your own ARC (advanced reading copy). Very helpful. She provides instructions for .doc, .rtf, and .pdf formats.
I found the macros easy to do and I got it right the first time. Give it a try!
