Copy Ease
Copy Ease will copy the ease data of the active F-Curve’s selected keyframes. If you want, you can also copy the ease of just one keyframe and paste it to many other keyframes. When Copy Ease is clicked, you’ll see how many keyframes were copied in Blender’s Status Bar.
Paste Ease
Ideally, your target F-Curve(s) will either share the same number of keyframes as the source F-Curve or only one keyframe was copied from the source F-Curve. If the number of copied keyframes and target keyframes don’t match, Paste Ease will use as many of the copied keyframes as possible.
Note
If you have just one object selected or your property is not animatable, you won’t see the Key Selected Object options.
Redo Panel
The options for this operation will appear in the Redo Panel at the bottom left of the Graph Editor. The options are:

Paste the handle’s angles along with the Ease.
