 Bézier Spline: Bézier splines are the default curve type. Three points for each keyframe
on the spline determine the smoothness of the curve. The first point is the actual
keyframe, representing the value at a given time. The other two points represent
handles that determine how smoothly the curve for the segments leading in and out
of the keyframe are drawn. Bézier is the most used spline type because Bézier splines
allow you to create combinations of curves and straight lines.
Bézier spline.
 Modify with > B-Spline: B-splines use a single point to determine the smoothness of
the curve. Instead of using handles, a single control point determines the value as well
as the smoothness of the curve. Holding down the W key while dragging left or right on
the control point adjusts the tension of the curve.
B-spline.
 Modify with > Cubic Spline: Cubic splines are similar to Bézier splines, in that the spline
passes through the control point. However, Cubic splines do not display handles and
always make the smoothest possible curve. In this way, they are similar to B-splines.
This spline type is almost never used.
Cubic spline.
 Modify with > Natural Cubic Spline: Natural Cubic splines are similar to Cubic splines,
except that they change in a more localized area. Changing one control point does not
affect other tangents beyond the next or previous control points.
