box is drawn around those points. Otherwise, you can drag the shape box around the area of
control points you want to include.

handle. Dragging a handle on the side of the shape box resizes the polyline along a

buttons, or from the polyline’s context menu.
The Show Key Points and Show
Handles buttons in the toolbar.

closely together and to avoid accidentally modifying controls and handles that are adjacent to
the intended target.
