Keyboard Shortcut Editor - User Interface

Not sure what’s the question?

To de-duplicate we have the context - so Ctrl+A means selecting all notes in the note list, or selecting all text in the text editor. I believe that’s the Source column in your mockup?

As for the shortcuts being enabled/disabled, it’s up to the component to handle this at the moment. For example, formatting shortcuts are disabled when only the note viewer is visible.
