The Select Previous/Following Keyframes commands aren’t available if more than one keyframe is selected.

Determining where to add and modify keyframes
You can freely change any keyframe attribute. Because After Effects provides more than one view of a keyframe,
where you modify it depends on what you want to do as well as the type of keyframe and layer property. All layer
properties are temporal—they can change the layer over time. Some layer properties, such as Position, are also
spatial—they can move the layer across composition space. You modify some attributes of a spatial layer property in
different panels than you do temporal properties.
Before you make any changes to a keyframe, make sure that the current-time indicator is positioned at an existing
keyframe. If you change a property value when the current-time indicator is not at an existing keyframe, After Effects
adds a new keyframe. However, if you double-click a keyframe to modify it, the current-time indicator location is
not relevant, nor is it relevant when you change a keyframe’s interpolation method.

To set keyframes for layer properties
1
In the Timeline panel, select the layer that you want to animate, and then select the layer property that you want
to animate.
2
In the Graph Editor, click the Show Properties menu
and select Show Selected Properties.
3
Move the current-time indicator to the time where you want to begin the animation.
4
Set the layer property to the value you want at that point in time; for example, move the layer to a new position.
5
Do one of the following:
•
Click the Stopwatch icon
next to the property name to activate it. After Effects creates a keyframe at the current
time for that property value.
•
Choose Animation > Add
[x]
Keyframe, where
[x]
is the name of the property you are animating.
6
Move the current-time indicator to the time where you want to add an additional keyframe.
7
Change the value for the property in the layer outline, or Ctrl-click (Windows) or Command-click (Mac OS) in
the graph to insert a new keyframe.
8
Repeat steps 6 and 7 as many times as you want to add more keyframes.
To add a keyframe without changing a value
1
In the Timeline panel, select the layer you want to animate.
2
Display the layer property for which you want to add a keyframe. The property must already contain at least one
keyframe, and the stopwatch must be activated.
