A control tip is a brief phrase that describes a control, a Page, or a Tab. The control tip appears when the user briefly holds the mouse pointer over a control without clicking. A control tip is very similar to a ToolTip. The difference is that Microsoft Forms provides ToolTips to developers at design time, and developers provide control tips to end-users at run time.
If you assign a control tip to a MultiPage or a TabStrip, control tips for the individual Page or Tab objects within the MultiPage or TabStrip are not displayed.
