You've studied the other three windows, and now we'll look at the Dope Sheet in a little more detail.
The Dope Sheet is descended from the animation timing sheets used by early animators that we talked about in Chapter 7, Planning your Work, Working your Plan. You can move, subtract, and add keyframes, but unlike the Graph Editor, you have no control of the Bezier Curves that control the motion. The window controls are the same as the Graph Editor controls that you studied in Chapter 3,Controlling the Lamp, the Camera, and Animati ng Objects:

Select Dope Sheet from the menu.
Move the cursor to the border between the Dope Sheet and the 3D View window...
