Underlining

Everyone knows that you can underline text by simply selecting what you want underlined and then clicking on the Underline tool on the ribbon or toolbar. This adds a single underline. If you want a double underline, you can add one quickly by simply holding down the Shift key as you click on the underline tool. The double underline is added to your selected text. (Holding the Shift key to get a double underline doesn't work in Excel 2007. Instead, you must click the down-arrow at the right of the Underline tool and then select Double Underline.)

If you want any fancier underlines, you must display the Font tab of the Format Cells dialog box. You do this in Excel 2007 by displaying the Home tab of the ribbon and clicking the small icon at the bottom-right of the Font group. In previous versions of Excel you choose Cells from the Format menu.
