You can delete keyframes independently from drawing exposure.
NOTE If you select a keyframe in the Timeline view and press the Del key, you will also delete the drawing exposure. To only delete the keyframe, you must use the Delete Keyframe command.

- In the Timeline view, select a keyframe and do one of the following:
- Right-click and select Delete Keyframes.
- From the top menu, select Animation > Delete Keyframe.
- Press F7.
- In the Timeline View toolbar, click on the Delete Keyframes button.
- Use the Transform tool to select a keyframe to delete from the trajectory in the Camera view and press Del.
