Mac Text Editor (with function list) [duplicate]
You could try out TextMate for Mac. You can download bundles for it which include all kinds of function and code shortcuts.
TextMate is my editor of choice. It's slick, powerful, and very expendable with bundles.
Other to look into are TextWrangler (free) which offers some of the same functionality, SubEthaEdit which allows you to code in sync with other people, and Coda which offers an "all-in-one" coding experience.
