How do I manually animate hair??

This is driving me nuts. I can’t figure out how to manually manipulate hair particles and key the changes I make to the strand over time.

Animating Curve Guides doesn’t seem to work. The hair strand apparently ignores any changes to the Curve Guide over time. (Not to mention that the fact that the hair no longer updates live when editing the curve is a pain in the ass)

I can bake the hair particles and then manipulate them in particle mode, but I can not find any way to key the manipulations I make.

Am I missing something?

Which version of Blender are you using?
