Some Emacs extensions that I find useful.

• Elscreen manages window configurations in a screen-like fashion. If you're already using screen, this extension has a very low barrier to entry.

  Other Emacs users also find winner-mode useful, which comes with recent Emacs versions.

• Magit: Very nice git integration.
• Notmuch: Fantastic mail indexing tool that comes with an integrated mail reader that runs in Emacs. I use it in combination with offlineimap and would not trade it in for Thunderbird any more.
• Emacs Muse: It generates this homepage. I'm sometimes not sure whether something markdown-based wouldn't have been a better choice, but now I'm stuck with it.
• For Lisp
  • Paredit navigates and manipulates the parenthesized Lisp expressions. I don't want to edit Lisp without it any more.

    Paredit keeps your parentheses balanced, so you never have to count.

    Paredit cheat sheets:

    • on mumble.net
    • on EmacsWiki
  • Geiser (for Schemes)

    Nice Scheme mode that integrates nicely with Guile.

  • SLIME (for Common Lisp)

    The Common Lisp IDE. :)
