 +  * A transformation requires a pivot point and a transform orientation. 
 +  * if a single object is selected, the pivot point is the object origin.  The object origin is by default the bounding box center, but it can be moved using the 3D cursor. 
 +  * If multiple objects or vertices are selected, the pivot point is at the average point of the selected objects. 
 +  * The transform orientation can be selected on the 3D viewport header, see above. 
 +  * The transform gizmo visualizes the pivot point and the transform orientation.
