How to send the escape character on OS X terminal?
The ^] means ctrl + right bracket. As strange as that is, it works. You'll be taken to the telnet prompt, where you can type quit.
On international keyboards the ] character is often not a single key, and needs to be replaced with some other key. The correct key is typically the key to the right of P or the next key after that.
Here's a list based on comments below:
- Finnish, Swedish, Norwegian, Danish: ctrl + å
- French: ctrl + 6
- German: ctrl + ü
- Swiss: ctrl + ¨
- Hungarian: ctrl + 5
- Portuguese: ctrl + ´
- Dutch, Belgian: ctrl + $
- Canadian French: ctrl + ç
- Italian: ctrl + +
Workaround for those who have problems finding the shortcut:
Change your systems keyboard language to U.S international - PC (System Settings/keyboard/input sources)
Look at an image of a US keyboard layout and ctrl+] the corresponding keys on your keyboard
