time marker (red vertical bar) is at frame 60. Click and drag the boy to the right of the
Stage. This will represent the second keyframe in the animation (Figure 3.8).

Step 5: Create a motion tween
Now that you have established a start keyframe and an end keyframe, it is time to

the walker layer in the Timeline. Click on the first keyframe on frame 1. Go to the
