Preferences > Advanced Preferences
Advanced preferences gives you a view of all your raw preferences data.
The majority of preference settings can be more easily and safely modified via the other preference panels. Normally you should not need to use this display to change settings. Do so with caution because there is no validation, and invalid or missing settings can cause unexpected errors and/or loss of data. You may be instructed to change or add settings here in order to access experimental or under-development features e.g. if somebody developed a plugin and provided a setting, but didn't get around to creating a more attractive interface for changing it.
As you can see, your preference data is composed of a set of name->value pairs. The setting names are often "namespaced" with dot ('.') separated words. Many JOSM plugins will store preferences grouped in a namespace.
Preference data is saved to a file in 'Applications Settings' folder (windows) or the hidden system folder ~/.josm (linux). You can get a similar raw view by viewing this file, but this 'Advanced' preferences panel is intended to provide a easier alternative.
