Work with property keyframes
You can edit the shape of a property curve by adding, removing, and editing property keyframes along each graph.
•
To add a property keyframe to a property curve, place the playhead in the desired frame and click the Add or
Remove Keyframe button for the property in the Motion Editor.
You can also Ctrl-click (Windows) or Option-click (Macintosh) the graph in the frame where you want to add the
property keyframe.
You can also right-click (Windows) or Command-click (Macintosh) the property curve and choose Add Keyframe.
•
To remove a property keyframe from a property curve, Ctrl-click (Windows) or Option-click (Macintosh) the
control point for the property keyframe in the property curve.
You can also right-click (Windows) or Command-click (Macintosh) the control point and choose Remove
Keyframe.
•
To toggle a control point between corner point and smooth point modes, Alt-click (Windows) or Command-click
(Macintosh) the control point.
When a control point is in smooth point mode, its Bezier handles are exposed and the property curve passes
through the point as a smooth curve. When a control point is a corner point, the property curve forms an angle
when it passes through the control point. Bezier handles are not exposed for corner points.
To set the point to smooth point mode you can also right-click (Windows) or Command-click (Macintosh) the
control point and choose Smooth Point, Smooth Right, or Smooth Left. To set the point to corner point mode,
choose Corner Point.

To move a property keyframe to a different frame, drag its control point.
You cannot drag a property keyframe past the keyframes that follow or precede it.
•
To toggle a property keyframe for the spatial properties X, Y, and Z between roving and non-roving, right-click
(Windows) or Command-click (Macintosh) the property keyframe in the Motion Editor. For more information
about roving keyframes, see “
Edit the motion path of a tween
” on page 195.
You can also turn off roving for an individual property keyframe in the Motion Editor by dragging the roving
keyframe to a vertical frame divider.
