property at the current time whenever you change the property value.

Set the layer property to the value you want at that point in time; for example, move the layer to a new position.

time for that property value.
• Choose Animation > Add [x] Keyframe, where [x] is the name of the property you are animating.
Move the current-time indicator to the time where you want to add an additional keyframe.

is after the last keyframe for that layer property, the new keyframe will have the same value as the preceding
keyframe. Otherwise, the new keyframe's value will be an interpolated value based on the previous and next
keyframe values.

• Click the keyframe navigator button
• Choose Animation > Add [x] Keyframe, where [x] is the name of the property you are animating.
