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.

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.

Place the pointer over a keyframe in Graph Editor mode to see the layer name, property name, time, and value of the keyframe. Place the
pointer over a segment between keyframes to see the corresponding information at any time.

Click a keyframe in layer bar mode to show the keyframe’s time and interpolation method in the Info panel.

Click a keyframe or segment between keyframes in Graph Editor mode to show a property’s minimum and maximum values and the speed at
the current time in the Info panel.

Alt-click (Windows) or Option-click (Mac OS) two keyframes in layer bar mode to display the duration between them in the Info panel.

Jeff Almasol provides a script on his

redefinery website

that creates new layer markers (either on the selected layer or on a new null layer) with

comments that provide information about keyframes at the same times.

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).

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.

1. In the Timeline panel, display the layer property containing the keyframes you want to copy.

2. Select one or more keyframes.

3. Choose Edit > Copy.
