Word and the Thesaurus

Look, Microsoft Word, let's get one thing straight. I will never - not ever - ask you to give me a synonym or antonym for a comma, a period or any other type of punctuation. When I press Shift-F7, if you're on a punctuation mark, for God's sake, assume that I would like a synonym for the word NEXT TO the punctuation mark. It shouldn't be that difficult. 99% of the time, it's the last word on the line.
