Using the Motion Editor in Adobe Flash Professional, you can control the shape of each property curve of a tween by editing the curve of each graph with standard Bézier controls. These controls are similar to working with the Selection tool or the Pen tool.
Move a curve segment or control point upward to increase the property's value; move it downward to decrease the value. Reposition property keyframes to different frames of the tween span to change how the tween appears.
To change the shape of a curve segment between two control points, drag the segment. When you drag a curve segment, the control points at each end of the segment become selected. If the selected control points are smooth points, their Bézier handles appear.
