===ESCAPE CHARACTERS===

When a pseudo-terminal has been requested, ssh supports a number of func‐
tions through the use of an escape character.

A single tilde character can be sent as ~~ or by following the tilde by a
character other than those described below. The escape character must
always follow a newline to be interpreted as special. The escape charac‐
ter can be changed in configuration files using the EscapeChar configura‐
tion directive or on the command line by the -e option.

The supported escapes (assuming the default ‘~’) are:

  ~.  - 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

Kill an unresponsive SSH session -> type -> newline ~..
Kill multiple chained SSH sessions-> type -> newline ~~~.
SSH prompt -> type -> ~C
