Key Interpolation

All pertinent keyframe interpolation properties can be defined here when new keyframes are generated (using the red buttons in the Animation palette). Note that keys will be created with Interpolation set to Spline to preserve the existing FCurve shape if they are created while pressing the Ctrl key.

Overdub

If a keyframe already exists, the existing keyframe’s interpolation type will be maintained when a new keyframe is recorded (only the Value Key will be overwritten).
