Selected points on curve

This example uses a continuous line, but the functionality works in the same way for a Bézier curve or arc-line.

You can select a point:

A red circle is placed on the selected point.

Note: You can select additional points graphically using the Shift key. You can deselect points using the Ctrl key. Shift plus a drag box selects all the points in the box and Ctrl plus a drag box deselects all the points in the box.
