Node and System Preferences
Preference nodes store system preferences and configuration data. Each system preference contains a key-value pair that is associated with a preference path. You can add or remove a preference node, but you cannot edit them. You can export node information to an XML file, which includes the application name, path of the node, and preference keys and values.
When you click a node, you see a new page that lists all the Preferences for that node.
Each page shows 10 entries; you might need to navigate through the pages to find the
entry you are looking for.
