Shortcut for accessing ssh

SSH Password

I set up my ssh such that I don't have to put in the password every time and that I have a shortcut to get to the remote machine.

In this case I'm logging into a school computer named csil.  So I made an alias:
       alias csil='ssh csil'

This calls on ~/.ssh/config which looks like this:
       Host csil
           HostName address.to.remote.computer
           User username

Then in order to not put in the password every time, I followed a site's instructions:

1) Generate a ssh key (though I already had one set up so I didn't need this step, it would be nice to know if I could have multiple keys though):
     ssh-keygen -t rsa  # It asks for some stuff, just hit Enter (three times).
2) Copy the file onto the remote server:
     ssh username@ssh.server.com mkdir -p .ssh — Server password
     cat .ssh/id_rsa.pub | ssh username@ssh.server.com 'cat >> .ssh/authorized_keys' — server password.
