Escape character ^] not working from Mac terminal If I ssh into an Ubuntu machine from my Mac with a "UK extended" keyboard and run telnet localhost 4730 I see:

me@ip-10-xx-xxx-30:~$ telnet localhost 4730
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.


But ctrl + ] does not work from a terminal on Mountain Lion. How can I resolve this?
Turns out if I hit return after Ctrl+] it works.
