The control's ScrollPos, ScrollX and ScrollY properties specify the surface's scroll position. The ScrollX property is equivalent with ScrollPos(False), and the ScrollY property is equivalent with the ScrollPos(True). Use the ScrollTo method of the control to scroll the surface at specified position. The MovePoint method of the control moves the surface from the one point to another. The MoveCorner method scrolls the surface from a corner to another. The ScrollTo method ensures that the element fits the surface's visible area. The AllowMoveSurface property specifies the combination of keys that allows the user to move the surface.
