Grasp and Scroll is active only when the left mouse click is in hand mode, that is, when the open-hand button is pressed as in Figure 3.12. The cursor in hand mode is an open hand as in Figure 3.15. As soon as left mouse button is pressed down, the cursor turns to a closed hand, as in Figure 3.16. It indicates the canvas will move in the same direction that the cursor moves as long as the left mouse button remains pressed. The grasp and scroll mode in the time ruler canvas can move only horizontally, but the grasp and scroll mode in the timeline canvas allows movement both vertically and horizontally.
