Hi,
I think the section name should be more explicit. Not everyone that reads “Shortcuts” thinks about keyboard shortcuts. They can also think about “link” shortcuts that a user may want to have in a side panel for instance. So I’d use “Keyboard Shortcuts” or “Shortcut Keys”.
I agree with the others that having an accordion menu would be better, with “Keyboard Shortcuts” being a section of the “Preferences” category, for instance. Until we have this, I’d go with what’s easier to implement.
I understand you want this feature to be discoverable, and having a top level category for this certainly helps with that, BUT I think most users won’t change the default shortcut keys AND if they do it they do it once. So I don’t think it deserves to have a top level category for something you access very rarely, which is why I’m leaning towards solution B (subcategory), which will be consistent with a future accordion menu where “Keyboard Shortcuts” won’t be a top level category but a section (subcategory).
Thanks,
Marius
