You meant lowercase or uppercase?

If it is the last one, here is from the man pages, used for port forwarding:
Code:
     -R port:host:hostport
             Specifies that the given port on the remote (server) host is to be forwarded to the given host and port on the local side.  This works by allocating a socket to
             listen to port on the remote side, and whenever a connection is made to this port, the connection is forwarded over the secure channel, and a connection is made
             to host port hostport from the local machine.  Port forwardings can also be specified in the configuration file.  Privileged ports can be forwarded only when log-
             ging in as root on the remote machine.  IPv6 addresses can be specified with an alternative syntax: port/host/hostport.
