You can make a group of frames to help organize an animation. A group of frames is called a Scene. A scene must have at least two frames, or a frame and a sound.
Select the frames in the Timeline or Storyboard you want to group. The selected frames must be continuous.
Press and hold the Shift key on the keyboard.
Click the first frame you want to add to the scene.
Click the last frame you want to add to the scene.
All the frames will be selected.
