E (1970s text editor)

E is a text editor that was developed in the 1970s, primarily by David J. McNab, at Bell Labs. It is notable for being one of the early screen-oriented text editors designed for use with Unix systems. E is characterized by its simplicity and efficiency, allowing users to edit text files directly in a terminal environment. One of the key features of E is its model of operations, which allows users to navigate and manipulate text efficiently through a combination of keyboard commands.
