Cisco ASA Ping Escape Sequence

I couldn't for the life of me remember what the escape sequence was for pinging from a Cisco ASA firewall.

BARNEYGUMBLE(config)# ping 111.111.111.111

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 111.111.111.111, timeout is 2 seconds:

?????

Success rate is 0 percent (0/5)

BARNEYGUMBLE(config)#

I dug around on the web and found that it is Ctrl-Shift-6.
