Editing, moving, and copying keyframes
View or edit a keyframe value
Before you change 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 the interpolation method of a keyframe.
• Move the current-time indicator to the time of the keyframe. The value of the property appears next to the property
name, where you can edit it.
• In layer bar mode, right-click (Windows) or Control-click (Mac OS) the keyframe. The keyframe value appears at
the top of the context menu that appears. Choose Edit Value to edit the value, if desired.
• Place the pointer over a keyframe in layer bar mode to see the time and value of the keyframe.
• Click a keyframe to show information regarding its value, speed, and interpolation method in the Info panel. Different
information is shown depending on whether the Timeline panel is in Graph Editor mode or layer bar mode.
Note: When a keyframe is selected, You can also place the pointer over a keyframe or the curve between keyframes in the
Graph Editor to see some of this information.
• Alt-click (Windows) or Option-click (Mac OS) two keyframes in layer bar mode to display the duration between
them in the Info panel.

or on a new null layer) with comments that provide information about keyframes at the same times.

"Layer properties in the Timeline
Copy and paste keyframes
You can copy keyframes from only one layer at a time. When you paste keyframes into another layer, they appear in
the corresponding property in the destination layer. The earliest keyframe appears at the current time, and the other
keyframes follow in relative order. The keyframes remain selected after pasting, so you can immediately move them in
the destination layer.
You can copy keyframes between layers for the same property (such as Position) or between different properties that
use the same type of data (such as between Position and Anchor Point).
Note: When copying and pasting between the same properties, you can copy from more than one property to more than
one property at a time. However, when copying and pasting to different properties, you can copy only from one property
to one property at a time.
