Create Custom ScreenTips for Shapes in MS Office Visio 2007
Shape ScreenTips in Microsoft Office Visio are the boxed text that appears when you point to a shape. Some Visio shapes have built-in ScreenTips—usually the name of the shape (such as the name of a workflow step). However, you can edit existing ScreenTip text or create new ScreenTip text for shapes that don’t have a built-in ScreenTip.
To create or edit a ScreenTip:
1. Select the shape.
2. On the Insert menu, click either Shape ScreenTip or Edit Shape ScreenTip, as applicable.
3. In the Shape ScreenTip dialog box, type or edit the ScreenTip text.
4. Click OK.
