A generalized text editor

TL;DR: To understand how people interact with powerful computer systems, the commands people use and the errors they made when performing office work with the UNIX operating system are analyzed, using several multivariate statistical analyses.

TL;DR: An editor is described that represents files using a generalization of AVL trees called “AVL dags,” which makes it affordable to automatically retain past versions of files.

TL;DR: This work applies the same heuristic to the design of interactive computer systems, noting that a number of existing successful interactive system styles can be viewed as the outcome of this approach.

TL;DR: An editing system for use in a virtual machine environment in which two virtual machines having corresponding virtual storage areas are operatively related to one another is presented in this article, which allows a first virtual machine to print, display, modify and otherwise control and process information stored in a second virtual machine storage area.

TL;DR: The nature and implementation of the file system and of the user command interface are discussed, including the ability to initiate asynchronous processes and over 100 subsystems including a dozen languages.

TL;DR: This paper describes a programming system based on the metaphor of communicating objects which provides flexibility, modularity and compactness, and a corresponding virtual memory is described which offers dense utilization of resident space.

TL;DR: The paper summarazes the LISP style of interactive programming for readers outside the LisP community, describes those propertms of LisP systems that were essential for the development of this style, and discusses some current and not yet resolved issues.
