Comment Just don't close Emacs (Score 2) 592
The trick is one never closes Emacs down - so it's always there. Just flick to the window with your Emacs, edit the file, save it, and go back to what you were doing. Those "editor AND the kitchen sink" jokes are very true, but you only have to open it once.
Even better, using TRAMP you can be running your Emacs as your normal user, and use the sudo method to edit a system config file - avoiding running the editor as root. Pretty nifty, eh?
I'm proud of myself - two holy wars (Vi/Emacs and su/sudo) in one post!
