Just wondering what feature you were talking about... I was concerned I might be misunderstanding the original question.

In any software product, you would have to provide a criteria for the removal of the text... you want portions of the document deleted if they meet some condition. But what condition? I'm with Ulodesk... create a style for each category and apply the styles as you go. What could be easier than selecting text and clicking a "category" (style name)?

Then you can replace all text with the Meat "category" with empty strings.

I think in Word, it might be easier than Excel, because in Word you can replace with empty strings, but it takes code to delete worksheet rows.
