• 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
Keyframe Thinning.
• Set to Curve Snapshot: If “Take/Show curve snapshot” is turned on (see Keyframe
Editor Control Buttons.), this option reverts any keyframe changes made in the
currently selected curve back to the most recent snapshot. For more information,
see Curve Snapshots.
Animation Menu States
Depending on the current condition of the parameter for the selected object, the
Animation menu displays a different icon. The following table shows the Animation menu
icons.

for this parameter.
Current Keyframe
This parameter is being controlled by a behavior,
as opposed to a keyframe. When a behavior is
applied to a layer or group, the name of the
behavior also appears in the Animation menu.

Keyframe Editor Control Buttons
In the lower-left corner of the Keyframe Editor, five buttons provide additional control
over the Keyframe Editor window: Snapping, “Show audio waveform,” “Fit curves,” “Clear
curve list,” and “Take/Show curve snapshot.”

Snapping: When snapping is turned on, keyframes snap to other keyframes, markers,
grid points, and other snappable items.
