teco

Powerful and compact editor with nongraphical user interface

TECO is the grand old text editor. It is a powerful and compact precursor to EMACS, and has a completely nongraphical user interface. It is very fast (probably the fastest editor in the world) and has a macro language. TECO was written by Dan Murphy (http://www.opost.com/dlm) at Digital Equipment Corporation in 1962. This is based on Pete Siemsen's TECOC implementation, and comes with a copy of the original's DECUS TECO documentation.
