My job involves checking for definitions in legal documents for clients. I want to ignore certain capitalised terms that never need defining (countries, months etc). I'd like to build up a list of these terms and then at the click of button highlight them throughout a document, so I'm left only checking relevant terms. How do I do this?

This is a big thing - it's what I do about 30 hours a week - so I'd really appreciate any help (bearing in mind that I've never used macros or VBA before and have limited understanding of how they work or whether they are what is needed).

Thanks
Bertie
