A trick I learned recently: create .ssh/config

File format: as many of the following blocks as you like

  Host $ALIAS <-- whatever you want here
  Hostname www.example.com
  User someuser
  Port 1234

You can now ssh to that server as that user by doing "ssh $ALIAS" on the command line, without needing to specify the port or user with the usual command line arguments, or necessarily spell out the entire host name.
