# Flipping Channels and Keyframes

Select Negate in the Curve Functions box to flip a channel or a group of keyframes vertically. Select Reverse to flip a channel or a group of keyframes horizontally. Typically, you reverse or flip keyframes so that you can create symmetry with an animation. For example, use Reverse on an image that is warping from a sphere to a flat plane so that it then goes from a flat plane back to a sphere again. Perform these functions in the Animation Curve window.

To negate or reverse a channel or group of keyframes:

1. Access the Animation Curve window.
2. Select a channel or group of keyframes.
3. From the Curve Functions box in the Keyframe tab, select Negate or Reverse.

   The selection is flipped horizontally (negate) or vertically (reverse).
