Motion panel > PRS Parameters rollout
Create Key/Delete Key The six buttons in the PRS Parameters rollout let you
create or delete a transform key at the current frame. These buttons become
active or inactive depending on the existence of a key type at the current
frame.
For example, if you're on a frame containing a Scale key, the Scale button is
inactive in the Create column, because a key already exists. At the same time,
the Position and Rotation buttons are inactive in the Delete column because
there are no keys of that type to delete.
Position/Rotation/Scale Determines the contents of the Key Info rollouts
that appear below the PRS Parameters rollout in the Motion panel.
