1 Move your mouse cursor close to the end of the tween span in the city layer.
Your cursor changes to a double-headed arrow, indicating that you can lengthen
or shorten the tween span.
2 Click and drag the end of the tween span back toward frame 60.
Your motion tween shortens to 60 frames, so now the cityscape takes a much
shorter time to move.
3 Move your mouse cursor close to the beginning of the tween span (at frame 1).
P Note: If you have
multiple keyframes
in a tween, dragging
out your tween spans
will distribute all your
keyframes uniformly.
The timing of your
entire animation
remains the same; only
the length changes.

frame 60.
