Editing, moving, and copying keyframes
To view or edit a keyframe value
1 Right-click (Windows) or Control-click (Mac OS) the keyframe. The keyframe value appears at the top of the
context menu that appears.
2 Choose Edit Value to edit the value, if desired.
To edit keyframes with the Pen tool
Using the Pen tool to edit a keyframe for a spatial property in the Composition or Layer panel is similar to modifying
a path in a drawing application such as Adobe Illustrator. (See “Creating masks with the Pen tool” on page 245.) For
best results with the Pen tool, you should understand how Bezier interpolation affects graphs and the paths. With
Bezier interpolation, you can control the shapes of curves at vertices, making them into smooth curves or angled
corners.
1 In the Timeline panel, select the property for the layer you want to edit.
2 Select the Pen tool from the Tools panel.
3 In the Composition or Layer panel (depending on where the controls appear), do any of the following:
• Click the path to add a keyframe.
