In a motion-tweened framespan you can drag the object on the Stage and a new keyframe is automatically created. In shape-tweened spans the object is only selectable on a keyframe. To add additional locations or shape changes along a shape-tweened span you must add the keyframe first and then edit the shape. You can do this by using the Add Keyframe function in the Insert menu. Once the keyframe is added the shape at that point in the framespan becomes editable. Add a Keyframe to a Shape Tween Place the playhead between any two shape tweened keyframes. Click the Insert menu point to Timeline and then click Keyframe. TIMESAVER Press F6 to insert a keyframe.
