I seem to remember that MS Word had a feature whereby a name or a word that was used throughout a document could easily be changed. In other words, lets say a name appears 25 times in a Word doc. But I want to change that name to a different on. Rather than make that change 25 times, I thought Word had a feature where it could be done automatically.

I tried highlighting the name and then going to Tools>Spelling & Grammar but if the name is not misspelled, it ignores it.
