Mac Keynote: How do I add another bend point to a curved connector line (arc)? I am using Keynote 7.2 in Mac OS Sierra. I want to add a curved connection line (aka arc or curve) to my presentation but with multiple bend points. How do I do that?

Specifically, I am choosing "connector line" from the top menu.



I then want to add another green bend point to make the line curve multiple times. How do I do that?
The tool to use for this is the Draw with the pen tool.

This tool is found at the top right of the shape picker window.



To add a new point, drag a midpoint to divide a line and add a new point.  See the illustration below.
