Modify keyframes in the Timeline
When keyframes are visible in the Timeline, you can change their positions in time by dragging
them horizontally in the track. This does not modify the keyframe’s parameter value. Rather, it
changes the position in time when the keyframe occurs.
Although moving a keyframe in time does not change the parameter’s value, it can have a
significant effect on the nature of the animation. For example, if you have two keyframes that
animate an object from the top of the screen to the bottom over a duration of five seconds,
dragging one of the keyframes farther from the other forces the animation to occur more slowly.
When multiple keyframe values are set in the same frame, only one keyframe marker appears in
the Timeline. However, you can choose to edit any of its values.
