Time for action – adding keyframes in Graph Editor
3D View is not the only place in which you can add keyframes. Graph Editor actually gives you much better control while adding and manipulating keyframes. In 3D View, select the camera. The steps to add keyframes in Graph Editor are as follows:
Using the arrow keys, move the current frame indicator to frame 1.
With the cursor over Graph Editor, use Ctrl + MMB to zoom Graph Editor out so that you can see at least -10 to 10 on the vertical scale on the left side of Graph Editor. Look at the left side of Graph Editor. It's blank.
With the cursor over 3D View, press the I key and make a Location keyframe.
In Graph Editor, there are three colored lines, red, blue, and green, just like the 3D axis indicator. Since you have just made a Location keyframe, these are F-Curves for locations in X, Y, and Z. Use Ctrl + MMB to zoom in until you can see the red and blue lines clearly.
Use the arrow keys to move the current frame indicator to frame 21. Note...
