You use Bézier handle controls when you work with the Pen tool, the Selection tool, and the Subselection tool in Adobe Flash Professional. When a control point is in smooth point mode, its Bézier handles are exposed and the property curve passes through the point as a smooth curve. When a control point is a corner point, the property curve forms an angle when it passes through the control point. Bézier handles are not exposed for corner points.
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.
To learn more about working with Bézier handles, see the section titled Drawing with the Pen tool in the Flash documentation.
