Microsoft Office 2003 - Stop Squinting At Your Computer Screen! (Word 2003)
You probably already know how to use the Zoom feature to make your Word documents appear larger on the computer screen. But, did you know you can even zoom in on toolbar buttons? To make your toolbar buttons larger, select Tools | Customize from the menu bar. Switch to the Options tab, and select the Large Icons check box. The buttons become large even before you click OK to close the dialog box.
