One of three operations, Edit, Run, or Play, that you activate by double-clicking an OLE object that is embedded in an object frame. For example, you double-click an embedded sound object to play that object. Double-clicking an embedded Windows Paint picture will run Paint and enable you to edit the picture.
The primary verb is the default action supported by the OLE object. When the object is activated, the primary verb will determine what occurs unless another verb has been set using the object's Verb property.
