**"But why would you?  That brings it the point of being Pose to Pose animation which you stated in another thread is something that no one does.  In fact why reduce the amount of data in the first place?**

If Pumeco is correct in that this saves time please explain how."

pay close attention:

 There is a Difference between creating pose to pose animation from scratch using the "direct manipulation tool" (Sheesh!!)

...and  the editing of a "clean" sparse mocap file made possible by a key reducer function.

In the above image ""Jabba" is hand gesturing as he ridicules Luke Skywakers attempt to use an old jedi mind trick on him
but at frame 55 his hand enters his torso.

This is an easy fix as one merely grabs the key at frame 55 and pulls it down
smoothly flattening the frames preceding& following frame 55 until his hand
stops short of his belly but not adversely affecting the overall gesturing motions of his hand.
