Query system database in community edition

How do I query the system db in the cypher command line tool.There is no USE command offered in my community install to switch from the default into the system schema and I can't run any of the queries on the system database unless I can switch in to it. Is this correct? There are a number of commands in the cypher manual which need access to the system db

Can you elaborate on what these queries might be? Are you looking for these procedures?
