Modify keyframes and curves in the Keyframe Editor
Add or delete keyframes in the Keyframe Editor in Motion
To add or delete keyframes in the Keyframe Editor, select the Edit Keyframes tool (above
the parameter list), then perform the following tasks:
Add a keyframe
• In the parameter list (on the left side of the Keyframe Editor) in Motion, click the
Animation menu for any parameter, then choose Add.
Note: The Animation menu (a down arrow) is hidden until you place the pointer over the
far-right side of the parameter’s row in the list.
A keyframe is added at the position of the playhead.
Add a keyframe to an existing animation curve
• In the Keyframe Editor in Motion, 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 Set curve interpolation in Motion.
Add a keyframe to an animation curve and adjust its value
• In the Keyframe Editor in Motion, 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.
Delete a keyframe
In Motion, do one of the following:
• Select the keyframe in the Keyframe Editor, then press Delete.
Note: You can drag a selection box around multiple keyframes.
• Control-click the keyframe, then choose Delete from the shortcut menu.
• Move the playhead to the frame where the keyframe occurs, then do one of the
following in the parameter list:
• Click the Animation menu for the keyframed parameter and choose Delete.
The Animation menu is hidden until you place the pointer over the right side of a
parameter row.
• Move the pointer over the gray diamond (the keyframe), then click the minus sign (–)
that appears in the center of keyframe.
