# Adding Keyframes for Motion, Rotation, Skewing and Scaling

Keyframes lock a change in position, rotation and scale to a specific frame and store the value for that effect. The tool you have selected determines what kind of keyframe you create.

- Transform: creates a keyframe for motion, scale, rotation and skew values.
- Motion: creates a keyframe for the position values.
- Rotation: creates a keyframe for the angle values.
- Skew: creates a keyframe for the skew values.
- Scale: creates a keyframe for the horizontal and vertical scale values.

Marks in the Timeline identify keyframes for motion, rotation, skewing or scaling.

To add keyframes:

1. In the Timeline window, select the peg element.

2. Then, use the red frame slider to select the frame where you want to add the keyframe.

3. From the Tools menu, select the tool you want to add the keyframe into (Transform, Motion, Rotation, Skew or Scale).

4. Select Element > Peg > Add Keyframe. Toon Boom Studio adds a keyframe to the Timeline.
