Editing or adding keyframes on a property containing an expression

After you add an expression to a property, you can continue to add or edit keyframes to the property. The value of a keyframe at the time you create it or edit it is the value it would be without the expression applied. When an expression exists, you can create keyframes by using any of the following methods and the expression will remain valid:

• Click the keyframe box.
• Choose Animation > Add Keyframe.
• Position the cursor between keyframes and choose Edit Keyframe from the menu that appears.
