Remarks

Drag tool derivates are typically activated and deactivated on left mouse down and left mouse up events respectively The NDragTool class exposes the StartMouseButtonEvent and EndMouseButtonEvent properties, which help you control the drag tool start and end events (by default set to LeftButtonDown and LeftButtonUp respectively). The AbortKey property controls the key, which aborts the tool and is by default set to the Escape key.
