Sometimes you need to use the singular version of the command - in your case, shortcut/add usc=scene/open. I should have noted that in the help file.

(The reason is because behind the scenes - no pun intended - scenes/open is just a game-wide shortcut for scene/open and it doesn’t do stacked shortcuts.)

I’m not sure why you included the shortcut for help in your post? It looks like that one worked ok?
