scope | Scope of the Settings. The Scope determines where the setting appears: in the Settings or the Preferences windows. |
keywords | List of keywords to compare against what the user is searching for. When the user enters values in the search box on the Settings window, SettingsProvider.HasSearchInterest tries to match those keywords to this list. |
