Defaults write com.stairways.keyboardmaestro.editor DetailDisplayExtraStyle

Where can I check the settings from:
defaults write com.stairways.keyboardmaestro.editor DetailDisplayExtraStyle -string 'div.ActionComment div.UserText { font-family:"Monaco"; }'?

If you start at the Terminal with

defaults read com.stairways.keyboardmaestro.editor

I think you should be able to see all the current keys and their values.

I mean: where can I view the effect in the editor? I would like use my own font “Iosevka”.

defaults write com.stairways.keyboardmaestro.editor DetailDisplayExtraStyle 
-string 'div.ActionComment div.UserText { font-family:"Iosevka"; }

@peternlewis Is this working?

The only place it is visible is in the non-edit view of macros.
