In Excel 2007, there is an Increase Font Size command on the Home tab on the
Ribbon. In Excel 2003, you can customize the toolbar to include the Increase
Font Size command. Toolbars can be customized by right-clicking an existing
toolbar and choosing Customize from the Shortcut menu. Display the Commands
tab, the drag-and-drop the Increase Font Size command from the Customize
Dialog box to an open toolbar.

Once the button is on the toolbar, you can highlight text, then click the
Increase Font Size command to achieve the desired result.

Good Luck,

anything else in my document?
