I found an old response from 2014 that states:
There is an option box to the right of the classes text field that lets you select the class you wish to edit. It is not visible if you have focused on the classes text field. So remove your selector from the text field and that option box should re appear.
I absolutely don’t understand what this advice is communicating and I don’t presently see an option to the right of the classes text field. When I look at any options to the right of the classes names all I see is the a dropdown that allows you to rename or duplicate a class. I also see a dropdown that allows you to select pseudo-classes.
How do I edit the specific classes I’ve created? In my example I have two classes there. I want to select one and edit it.
