• Vi and Emacs
  
  NOT "Vi vs. Emacs" -- Despite twenty or thirty years of abuse thrown at each other by adherents of the Church of Vi vs the Church of Emacs, I feel the two editors are complementary, rather than antagonistic. They have a very different "look and feel", but that's not a real reason for choosing one over the other. They were designed for different jobs, they are better at different things, and I use both of them, depending on the job.
  
  
• Is there any way to run console emacs inside KDE?
  
  You may not have emacs installed. When I run emacs in the console, I get emacs. I do not have xemacs installed, just emacs.
  
  You might check and see if you actually have emacs on the machine, To check, try "ls -l /usr/bin/emacs. If you have emacs installed you will find that "/usr/bin/emacs" is a link to "emacs-nox. It could also be that /usr/bin/emacs is linked to xemacs on your machine.

  Telling Emacs about Modes and Files
  
  To tell Emacs to go into a major mode based on a file's extension, place this in your "~/.emacs" file:
  
  (setq auto-mode-alist (cons '("\\.java$" . java-mode) auto-mode-alist))
  (setq auto-mode-alist (cons '("\\.cxx$" . c++-mode) auto-mode-alist))
