Emacs Cheat Sheet from Stanford
Another cheat sheet from Princeton
A line numbering Emacs file using Marcus Triska's "linum" package. Use this as your .emacs file or copy it into your existing one appropriately. (If you have one already I assume you know how.)
A much simpler one which just turns on line-number-mode and column-number-mode by default; also font-lock-mode for syntax highlighting.
