LP, the Larch Prover -- Interrupting LP

Often one wants to interrupt an execute, order, critical-pairs, or complete command (e.g., to change the registry, to display the system, to alter the trace-level, or to freeze the system). This can be done by typing ^G (hold down the control key and type g), which will return the user to the LP command level (it may take several seconds for this to happen). The complete and order commands can be issued again to resume their execution.
