Yes, that works. But it seems unnecessarily indirect. When I'm typing a text cell, I hate to interrupt the flow of thought by going to a different cell to create the fraction, then put it into the text cell. What might be better is a Format menu entry for changing the fraction size change. Actually, the problem is even worse than fractions: integral signs, summation signs, etc., whose height one should be able to change easily (without the kludge of selecting the characters and specifying a different point size -- which then gets messed-up when you print or change to a different screen environment, such as Presentation). The interface design issue becomes how much does one want to tolerate on the Format menu, and how.
