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.
