your curve. For more information, see
Modifying Curves .
To lock or disable a keyframe
µ
Control-click the keyframe you want to modify, then choose Lock or Disable from the
shortcut menu.
Lock prevents any further modification to that keyframe. Disable makes a keyframe
temporarily ignored without deleting it.
Copying and Pasting Keyframes and Animation Curves
Keyframes and the animation curves they form can be moved from one parameter to
another using copy and paste commands. This technique can be useful for copying a
particular keyframe effect from one object to another, moving a keyframe path earlier or
later in the same parameter, or for creating keyframes on one parameter and applying
them to another parameter.
To copy keyframes, you must select the keyframes you want to copy, either individually,
or as an entire channel or channels.
To select keyframes
Do one of the following:
µ
Using the Edit tool, drag a selection box around the keyframes you want to select.
