Add, delete, and modify keyframes
To make basic edits to keyframes in the Keyframe Editor—adding and deleting keyframes,
modifying their values—select the Edit Keyframes tool (above the parameter list), then perform
the following tasks:
Add a keyframe
m
In the Keyframe editor, choose Add Keyframe from the Animation menu for any parameter.
A keyframe is added at the position of the playhead.
Add a keyframe to an existing animation curve
m
In the Keyframe Editor, double-click or Option-click the animation curve in the graph area.
A keyframe is added to the curve at the pointer position. The new keyframe is set to the
interpolation method used by the rest of that curve. For example, Position parameters use Bezier
curves by default, so new keyframes are added as Bezier keyframes. For more information on
interpolation methods, see
on page 474.
Add a keyframe to an animation curve and adjust its value
m
In the Keyframe Editor, Option-drag a curve segment.
A keyframe is added to the segment at the pointer position, and its value is displayed as you
drag the keyframe.
Change the value of a keyframe
Do one of the following:
m
In the graph area of the Keyframe Editor, drag the keyframe along the Y axis (up and down) to
change its parameter value. To change its position in time, drag along the X axis (left to right).
Press the Shift key while dragging to constrain movement to one axis. (To constrain keyframes
to the Y axis, select “Lock keyframes in time in Keyframe Editor” in the Time pane of the Motion
Preferences window.)
