# Moving a Vertex on a Motion Path

Since you create a motion path in the scene and not in the Channel Editor, you do not have to be positioned at a specific keyframe to move the vertices of a motion path. You can move vertices and tangent handles for any keyframe in the animation.

Moving a locked vertex on the spline changes the position of the object at that frame. A locked keyframe on the speed curve can only be moved along the horizontal axis (frame number). This changes the frame where the animation reaches a particular point on the spline, but not the shape of the spline. Thus only the animation timing is affected.

To move a vertex on a motion path:

1. From the Edit Mode box, select Move.
2. Select a vertex on the motion path.
3. Drag the vertex or keyframe to its new location.

To move a keyframe on the speed curve:

1. From the Edit Mode box, select Move.
2. Select a keyframe on the speed curve.
3. Drag the keyframe to a new position.
   NoteYou cannot move the first and last keyframes vertically because the timing of the animation must begin at 0% and end at 100%.

To move the speed curve in the Animation Curve window:

1. From the Edit Mode box, select Translate.
2. Select the speed curve.
3. Drag the curve horizontally to a new position.
   NoteYou cannot translate the first and last keyframes vertically because the timing of the animation must begin at 0% and end at 100%.
