3 Move the playhead to the position you want to create a keyframe, then enter a value in
the Custom Speed field.
For example, a value of 90 moves the object 90 percent of the way through the motion
path.
4 Continue moving the playhead and adding keyframes to obtain the result you want.
End Offset: A slider that lets you offset the end of the behavior’s effect relative to the
last frame of its position in the Timeline, in frames. Adjust this parameter to make the
object reach the end of the motion curve before the actual end of the behavior in the
Timeline. Using this slider to stop the effect, instead of trimming the end of the behavior
in the Timeline, freezes the object at the end of the motion path for the remaining
duration of the object. Trimming the end of the behavior speeds up the object.

Snap Alignment to Motion
This behavior aligns the rotation of an object to match all changes made to its position
along an animation path. This behavior is meant to be combined with behaviors that
animate the position of an object, or with a keyframed animation path you create
yourself.
For example, if you have a graphic of a fish to which you’ve applied the Motion Path
behavior, you can add the Snap Alignment to Motion behavior to make the fish point
in the direction it is moving.
