Helm is incremental completion and selection narrowing framework for
 Emacs. It will help steer you in the right direction when you're
 looking for stuff in Emacs (like buffers, files, etc).
 .
 Helm is a fork of anything.el originally written by Tamas Patrovic and
 can be considered to be its successor. Helm sets out to clean up the
 legacy code in anything.el and provide a cleaner, leaner and more
 modular tool, that's not tied in the trap of backward compatibility.
