Can't draw in Envelope

I have an issue where I try to draw in the Envelope area and nothing happens. I have a Mac so I’ve tried using control, command, shift and nothing happens. I also have a issue where I can’t type in my pitch range

The default for adding nodes in the genv is right click.br

You can change this in the settings menu to ctrl or double click.br

Changing pitch range you should click hold and drag up or down.
