Why I Still Use Emacs « Occasionally sane: "anything: anything is similar to OS X’s QuickSilver utility; you activate it, start typing what you want and it’ll show you all the possible results, organized by categories. By default, it looks at the files in the current directory, and the opened buffers I believe, but you can configure it to find all sorts of things, such as Emacs commands, man pages, recently opened files, functions, etc."
