         NoteThe X keyboard shortcut
               is designed to transform the currently selected item(s) by default.
               If no model is selected, the hotkey transforms any item under the
               tool cursor. If one item consistently transforms in the 3D
                  View despite the location of the tool cursor, it is selected.
               Click an empty region of the 3D View or press Ctrl
                  + D to cancel any current selection.
