is a list of gesture specifiers. A gesture specifier is an object that
When an interface is created, the break gestures are set such that typing any one of them when the interface is on top causes an "interface break". This means that, if the interface process is busy, it tries to break it. In a Listener tool, it tries to break the REPL. Otherwise it tries to find a process that appears busy, and breaks that. In the LispWorks IDE, if there is no busy process it raises the Process Browser tool. Otherwise it breaks the current process.

On GTK+ the list can be overriden by the resources file as illustrated in
