SSH Escape Sequence

If i'm SSH'd into a box and lose my internet connection, the ssh session will most likely just hang there like a retard. SSH has an escape sequence similar to telnet's ctrl+]

hit enter
then type ~.

That will close the ssh session and return you to the shell. ~? will return a help menu with different escape options that SSH accepts. the list is below:
Supported escape sequences:
~. - terminate connection (and any multiplexed sessions)
~B - send a BREAK to the remote system
~C - open a command line
~R - Request rekey (SSH protocol 2 only)
~^Z - suspend ssh
~# - list forwarded connections
~& - background ssh (when waiting for connections to terminate)
~? - this message
~~ - send the escape character by typing it twice
(Note that escapes are only recognized immediately after newline.)

Now you dont have to lose your terminal window! yay!
