You can change the position of a keyframe or tangent handle on an animation curve.

If you move a keyframe, the frame number (horizontal) and keyframe value (vertical) coordinates of the keyframe are updated and displayed. The shape of the curve is updated automatically.

If you move a tangent handle, the value of the slope is updated and displayed. After a tangent handle is moved, it appears as a solid square.

While moving a keyframe in the Animation Curve window, press Alt to snap the frame value (vertical axis) to the nearest integer. Press Ctrl+Alt to snap to the nearest multiple of ten.

To move a keyframe or tangent handle:

1. Access the Animation Curve window or the Track Editor. To both move keyframes on the Y-axis and adjust tangent handles, you must use the Animation Curve window.
2. From the Edit Mode box, select Move (or press spacebar+M).
3. Select and drag the keyframe or tangent handle that you want to move to a new position. You may have to click the Frame Chn button to view the curve.
   TipWhen you move keyframes in the Animation Curve window, you may want to move the keyframe strictly on the X-axis or strictly on the Y-axis. To lock keyframe movement to the X- or Y-axis, hold Shift as you move the keyframe. The keyframe movement will be locked to the X-axis if your initial movement is horizontal and to the Y-axis if your initial movement is vertical.
