8 Reposition the duplicated layer in the Canvas, press Shift and drag one of the corner
handles to uniformly scale down the layer.

choose Basic Motion from the pop-up menu and Motion Path from the submenu.
The layer moves from its original position toward the right and off the Canvas. Use the
Motion Path’s Direction parameter to change the direction in which the layer travels
over the motion path. The Direction parameter is only available in the Inspector.

pop-up menu.
The layer now travels from right to left.
11 In the mini-Timeline (immediately below the Canvas), drag the end of the Motion Path
behavior toward the left until its duration is 200 frames.
The layer moves faster along its path.
