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.

Subject: emacs -- simple

Hi,

I have a lot of plugins (CEDET for example) that start up when e-macs starts. Sometimes, I just want to open up emacs quickly to edit some textfile very quickly, and then close it and proceed. Since I have to SSH into remote servers, with all of the plugins, the latency is quite annoying.

Is there a way I can have the regular emacs command open up with all of my plugins, then have an emacs -s or emacs -simple to open up without the plugins?

Thanks a lot.

Jai
