This tool creates new keyframe data on a layer property in After Effects. It is a reversible write operation (keyframes can be deleted), with medium severity as misuse could corrupt animation timing but does not cause irreversible damage.

From the tool's own definition: "Add a keyframe to a layer property at a specific time with precise value control"

## Use case
