If you execute a long-running query or program in the SQL Window, Test Window, Command Window or Report Window, you can break it by pressing the "Break" button on the Session Ribbon or on the Quick Access Toolbar. Note that the "Session Mode" preference (Configure > Preferences > Oracle / Connection) must be set to "Multi Session" (the default) or "Dual Session". In Single Session mode the break function will not be available.
