JabRef is highly customizable, allowing users to get the behaviour they expect.
The Options menu allows you to configure the JabRef interface, and to set the default features of your libraries. Features specific to a given library are configured in the Library menu. For example, while the default key patterns are set in Options → Preferences → Citation key Generator → Key patterns, key patterns specific to a library can be set in Library → Citation key patterns.
