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?

Solution 1:

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.

Solution 2:

Here's another tip !

You can also "double click" at the green bend point and keynote will automatically convert curve connector line to elbow connector line.

This helps to avoid other shape if you create complicated diagram.
