| CreateDragSelection | Create a new selection object containing an image of all of the real selected objects. |
| DoCancelMouse | Overridden. Cancelling a drag involves moving the selection back to the original position before aborting the transaction. |
| DoClick | Any tool can call this method in order to implement the standard click behavior. (Inherited from Northwoods.Go.GoTool) |
| DoDragDrop | Call Control.DoDragDrop |
| DoDragging | Perform the drag, for both moving and copying, including the final move or copy on a mouse up event. |

| DoMouseDown | The view calls this method upon a mouse down event; all of the event information is provided by the LastInput property. (Inherited from Northwoods.Go.GoTool) |
| DoMouseHover | The view calls this method after the mouse rests for a while at a point; all of the event information is provided by the LastInput property. (Inherited from Northwoods.Go.GoTool) |
| DoMouseMove | Overridden. Mouse drags just call DoDragging and DoMouseOver. |
