Sometimes I see pre-defined shortcuts in macOS where one part of them are using the second level of keys, e.g. stroke "/" of the key 7. As everybody knows, at least this secondary level can be accessed by the shift key.
Well, coming from this pattern, I was a bit confused about such kind of pre-defined shortcuts: command+option+/. My initial assumption to utilize these kind of shortcut was to use modifiers like this command+option+shift+7, which wasn't working well unfortunately.
My assumption is that I have a fundamental misunderstanding in using secondary key strokes in shortcuts. Can you help me out with this?
