[Etoys] EToys question -- clearly I'm missing some key concept

Hi. I would like to use EToys for a project but I'm having a hard time
adding my own actions. I suspect that I am missing something obvious, and
would appreciate any pointers you could offer. I've tried to RTFM, but I
can't find the FM so I'm kind of stuck.
So... As a test case, I decided that I would make some simple methods to
animate the opacity of a Morph. I also wanted to add an instance variable
and manipulate it.
So I created a subclass of Morph and, on the class side, added:
( (slot grink 'grink is a nonsense variable' String readWrite
Player getGrink Player setGrink:)
(command changeOpacityLevel: 'change the opacity level'
and I created #getGrink, #setGrink:, and #changeOpacityLevel: on the new
subclass of Morph.
When I instantiate the new object and open an etoys viewer, the "seg"
category is there but it is empty.
I'm running the latest Squeak 3.9 image on a Mac, downloaded form squeak.org
