Using frames and keyframes

A keyframe is a frame in which you define a change in an animation or include frame actions to modify a movie. Flash can tween, or fill in, the frames between keyframes to produce fluid animations. Because keyframes let you produce animation without drawing each frame, they make creating movies easier. You can change the length of a tweened animation by dragging a keyframe in the Timeline.

The order in which frames and keyframes appear in the Timeline determines the order in which they are displayed in a movie. You can arrange keyframes in the Timeline to edit the sequence of events in a movie.
