Know how Excel has a feature called Conditional Formatting. Well I was wondering if there was something in Word that I can only describe as Conditional Highlighting.

I have several large documents that have to reference several different subject areas. I also have to be able to show my boss how these areas are covered in these documents. I was hoping there was something, perhaps a toggle that can be created, where I can select it and say; "Here are the areas that deal with Security...Here are the areas that deal with Validation...etc...

Any ideas?
