You can swap animation curves between two channels. Swap works in conjunction with Copy or Cut. You can also swap single keyframes but not a group of keyframes.

To swap two channels:

1. Select the first channel to swap.
2. Click Cut or Copy.

   The selection is copied to the clipboard.

3. Select the second channel to swap.
4. From the Curve Functions box in the Keyframe tab, select Swap.

   
   

   The selected channel is swapped with the channel in the clipboard.

5. Select the first channel and click Paste.

   The two channels are swapped.
