Use the Accessibility palette to define a custom tool tip for an object. For most objects, tool tips appear at run time when the user hovers the pointer over the object. Tool tips appear for some read-only objects, such as a paper forms barcode object, only when a screen reader is in use.You cannot have unique custom tool tip text and unique custom screen reader text for one object. You must choose one or the other. If you want a custom tool tip, type the custom text and either select Tool Tip from the Screen Reader Precedence list or do not include custom screen reader text. If you want custom screen reader text to be both the tool tip and the screen reader text, type the custom text and select Custom Text from the Screen Reader Precedence list.If nothing is specified in either the Tool Tip box or the Custom Screen Reader Text box, then the screen reader uses the caption for the tool tip and for reading.
2. Click the Accessibility palette and, in the Tool Tip box, type the text you want. To create a multiline tool tip, type the first line and then use the Ctrl + Enter command to go to the next line.
3. If there is also custom screen reader text defined for this object, and you want the screen reader to read the tool tip instead of the custom screen reader text, from the Screen Reader Precedence list, select Tool Tip.
