Ctrl-\ sends a SIGQUIT in most terminals:
happy-idiot-talk:~:% stty -a
speed 38400 baud; 80 rows; 80 columns;
lflags: icanon isig iexten echo echoe echok echoke -echonl echoctl

cchars: discard = ^O; dsusp = ^Y; eof = ^D; eol = <undef>;
eol2 = <undef>; erase = ^H; erase2 = ^@; intr = ^C; kill = ^U;
lnext = ^V; min = 1; quit = ^\; reprint = ^R; start = ^Q;
^^^^^^^^^^
status = ^T; stop = ^S; susp = ^Z; time = 0; werase = ^W;
The default action for a process receiving SIGQUIT is to halt
the program and dump core. See signal(3)
Cheers,
Matthew
