Searching for verb tenses
I need to search a large Excel document for verbs in the present and past tense. I would be satisfied if I could just find all words that end in "s" or "ed," but I can't figure out how to do that. When I search on "*s," for example, I get all words that have an s in them with a letter or letters before the s, such as "finished." Is there a way to indicate in the search field that "s" or "ed" should be the last letters? Thanks for your help.
