Footstep Adapt Locks group
Lock specified tracks to preven t automatic
adjustments being made to those tracks when
footsteps are moved in space or edited in time.
All the locks except for Ti me work for footstep
editing in space. Time locks upper bo dy keys
when footsteps are edited in time (Track View).
Adapt Locks only applies to a F ootstep animation,
not a freeform animation.
When you move a footstep in space or adjust
footstep timing, Biped automatically adapts
existing keyframes to match the new footsteps.
Adapt locks allows you to preserve the exact
position of already created keys for a selected track.
Adapt Locks does not need to be on all the time.

keys will retain their exact motion.
