Reversing, Locking, and Disabling Keyframes
You can reverse keyframes to reverse the corresponding animated effect without
re-animating it. Further, you can lock keyframes (individually or in groups) if you have a
complicated curve and you want to prevent further adjustment. Finally, you can disable
an entire curve to suspend animation for that parameter.
To reverse keyframes
1
In the graph area Keyframe Editor, drag a bounding box to select the keyframes to reverse.
2
Control-click a selected keyframe, then choose Reverse Keyframes from the shortcut
menu.
The keyframes are reversed.
To lock keyframes
µ
Select the keyframes to lock, then control-click a keyframe and choose Lock from the
shortcut menu.
Lock prevents further modification the keyframes.
Tip: You can also lock all keyframes in the Keyframe Editor by selecting “Lock keyframes
in time in Keyframe Editor” in the Time pane of Motion Preferences.
To disable a curve
µ
Select the keyframes to disable, then Control-click a keyframe and choose Disable from
the shortcut menu.
Disabled keyframes are ignored and have no effect on the object’s animation. If you
disable a keyframe, the curve readjusts itself as if that keyframe didn’t exist, even though
the keyframe is present in the Keyframe Editor, in a dimmed state.
