control point
The
points that define a path. Line segments and gaps have two control
points, at the start and end, cubic Bézier segments have four
control points: one at the start of the segment, one at the end of
the segment, and two others that define the curvature of the segment.
Adjacent segments share a common control point. When a path is under
construction, or is being edited, the control points are shown as
orange or red squares.
