As other mentionned, there's emacsclient, but also pay particular attention to the daemon mode.  Quite cool to run emacs as a daemon (you may have an instance of emacs running without having any associated window).

After that, you can have yourself some shortcuts. e.g. et to start a terminal style emacs (e.g. if you are in a shell and do not want another window), or ew, for a seperate window.


That way, you can keep a daemon running on the remote machine, and when you ssh to the remote machine, you can start a window immediately.
