|Visio Automation Reference|
Version Added: Visio 2000
expression A variable that represents a UIObject object.
To show ToolTips, you must set the DisplayTooltips property to True.
It does not matter which UIObject object you use when getting or setting this property. The property affects the entire application and always affects the appearance of ToolTips in the current visible set of toolbars.
Beginning with Microsoft Visio 2002, this setting corresponds to the Show shortcut keys in ScreenTips setting on the Options tab in the Customize dialog box (Tools menu), and is shared between Visio and all Microsoft Office applications.
