# Configuration

JabRef is highly customizable, allowing users to get the behaviour they expect.

The **File → Preference** menu command 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 **File → Preferences → Citation key generator → Key patterns**, key patterns specific to a library can be set in **Library → Citation key patterns**.
