You can perform the following modifications on frames or keyframes:
Insert, select, delete, and move frames or keyframes.
Drag frames and keyframes to a new location on the same layer or on a different layer.

Drag an item from the Library panel onto the Stage to add the item to the current keyframe.
Flash offers two different methods for selecting frames in the Timeline. In frame-based selection (the default) you select individual frames in the Timeline. In span-based selection, the entire frame sequence, from one keyframe to the next, is selected when you click any frame in the sequence. You can specify span-based selection in Flash preferences.
