Roving keyframes in Adobe Flash Professional let you create smooth animation across a motion path. When you paste a motion path onto a tween span, roving keyframes create the animation along the motion path so it moves at the same rate across the path that you paste. The animation is smooth and consistent across the path largely because the keyframes are not bound to frame boundaries. The keyframes will fall on or between frame boundaries as necessary to achieve this. This kind of keyframe is called a roving keyframe.
Note: You will find roving keyframes only on x, y, and z (spatial) properties.
The spatial properties (x, y, z) in the new motion model can contain roving keyframes that do not fall on frame boundaries. They are used to simplify the process of making motion across a bunch of spatial keyframes constant.
Use the Motion Editor to enable roving for individual property keyframes for x, y, and z properties. Roving allows the property keyframe to move to different frames or between individual frames in order to create smooth motion.
To learn more about working with roving keyframes, see the section titled Use roving property keyframes in the Flash documentation.
