# Adding Motion Points to a Motion Path

If you want to create a motion path that is not straight, you must add motion points to your motion path.

Motion points can be either keyframes or control points. Keyframes are locked to a specific frame number and control points are not locked.

- Add keyframes when you want to lock the position of the motion path to a specific drawing or image in an element to a position.
- Add control points when you want your element to reach a specific position, but you don’t need it to do so at a specific frame.

Then you can use the Motion tool to move the motion points and change the shape of the motion path.

| You cannot add control points to constant segments on motion paths. This is because constant segments do not interpolate (tween) changes in position, rotation or scaling between frames.

To add a motion point to a motion path:

1. Select a peg element in the Timeline window. The peg appears in all View windows. You can hide other elements to make it easier to identify and modify pegs.

2. Select Tools > Sceneplanning Tools > Motion. This activates the Motion tool.

3. Place the pointer over the motion path of the peg and decide which type of motion point you want to add.

- Press [Option] and click the motion path to add a keyframe. The mouse pointer becomes a square when it is over a spot where you can add a keyframe. A red point appears on the motion path after you click.
- Press [Shift] and click the motion path to add a control point. The mouse pointer becomes a diamond when it is over a spot where you can add a control point. A green point appears on the motion path after you click.

4. Drag the new point to a position where you want the motion path to be at that point. To nudge a motion point, you can also use the arrow keys. Press [Shift] if you want to move the motion point in larger increments.

- If you added a control point, notice how it changes position on the motion path. This is because the control point is not locked to a specific time frame.
- If you added a keyframe, notice how it remains at the frame you added it to. This is because the keyframe is locked at a specific time frame.
