GNU Emacs "is an extensible, customizable text editor - and more. At its core is an interpreter for Emacs Lisp, a dialect of the Lisp programming language with extensions to support text editing". Emacs has over 1000 commands allowing the user to combine them into macros to automate work. Development began in the mid-1970s and continues actively today. ~http://www.gnu.org/software/emacs/tour/
