Currently, ctrl+click is the way to add a new breakpoint in the automation function editor.
If you'd like to create a collection of breakpoints by typing the times and values, here's a way to do that:
In a Kyma Notebook, write the points as an Array of points, for example:
#({0@0} {1@1} {2@0})
Copy this expression (Ctrl+C), then go into the automation editor, select the points you'd like to replace, and paste (Ctrl+V).
Or generate points algorithmically, for example:
| r |
r := Random new.
(1 to: 10 collect: [:i | i @ r next]) asDisplayParameter
Select the three lines, evaluate them using Ctrl+Y. Then copy the Array (not including the enclosing single quotes) and paste into the function editor.
