This turns on/off your ability to perform a Drag. During a CrossScan, after a LineScan, if you have Double Click, Drag, Text Entry, or Auto-Repeat enabled, you will see the IconWindow with the icons representing those functions you have checked on. Clicking while the finger is pointing to the Drag icon will clear the IconWindow, reset the finger to the left edge of your CrossScanning area, and FingerScan to your desired beginning point of a drag process. The next click will begin a CrossScan (LineScan followed by FingerScan) to your desired destination of the drag.
