A superscript or subscript is a number, figure, symbol, or indicator that is smaller than the normal line of type and is set slightly above it (superscript) or below it (subscript). When you add a trademark, copyright, or other symbol to your presentation, you might want the symbol to appear slightly above the rest of your text. If you’re creating a footnote, you might also want to do this with a number.
