• Reduce Keyframes: Applies a “thinning” algorithm to the keyframes for the selected
parameter. This reduces the number of keyframes in a parameter while attempting
to maintain a similar curve shape. For more information on keyframe thinning, see
.
• Set to Curve Snapshot: If “Take/Show curve snapshot” is turned on (see
.), this option reverts any keyframe changes made in the
currently selected curve back to the most recent snapshot. For more information,
see
.
