To create a Solid or Outlined Arrow vector, select the tool and drag from the back of the arrow to the tip of the arrowhead:
The nodes are the same for both the Solid and Outlined arrow types:
Holding the Shift key down while dragging a gray endpoint node constrains the arrow to 45-degree angles.
Holding the Shift key down while dragging a red curvature node constrains the arrow to a straight line.
The fill lines are drawn automatically in the Outlined Arrow; there are no controls for them.
