Most controls allow you to specify a tooltip, which is a small piece of text that describes the control. The tooltip is displayed when the user moves the pointer over the top of a control, as shown in the following illustration.


Often, tooltips are used for fields that require additional explanation, such as buttons on a toolbar. To add a tooltip, select the control in the layout window and enter a value for the Tooltip property. You can also use the  Field_SetToolTip() function to set a tooltip from a script. Use the Field_GetToolTip() function to retrieve a tooltip.
