QUITKEY=key (or ^key)
Examples: QUITKEY=^\ (Control backslash)
QUITKEY=~ (tilde)
QUITKEY= (no quit key) (default)
(Unix only) Quitkey defines the key which Unix uses to abort a running process. Normally, the Unix "Quit" key is Ctrl+Backslash. Hitting this key while a process is running causes the SIGQUIT signal to be sent to the process. Since this signal is un-trappable, it invariably causes the process to abort with a core dump. The only defense an application has against this key is that it can be redefined or even disabled (prior to it being used.) Because of the obvious danger posed by the ability to abort A-Shell and cause a core dump just by hitting a key, the default is for the key to be disabled while A-Shell is running.
