the current-time marker 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.

Navigating and selecting keyframes
If you want to modify or copy a keyframe, first select it. After Effects provides many
methods for navigating to and selecting one or more keyframes.
To move the current-time marker to the previous or next keyframe:
Click a keyframe navigator arrow. The arrow to the left moves the current-time marker to
the previous keyframe. The arrow to the right moves the current-time marker to the next
keyframe.
To snap the current-time marker to a keyframe:
Press Shift as you drag the current-time marker to a keyframe.
To select a keyframe:
Click the keyframe icon in the Timeline window's time graph.
To select multiple keyframes:
Do one of the following:
Press Shift as you click to select multiple contiguous or noncontiguous keyframes.
•
Drag a marquee around the keyframes to select contiguous keyframes.
•
To select all keyframes for a layer property:
In the layer outline, click the layer property name. For example, click the word "Position" to
select all the Position keyframes for a layer.
Deleting keyframes
If you make a mistake while setting keyframes, or if you decide a keyframe is no longer
needed, you can easily delete one or more keyframes from a layer.
To delete a keyframe:
1 Select a keyframe. See "Navigating and selecting keyframes" on page 99.
2 Press Delete on the keyboard. Do not press Delete on the keypad (Windows).
