DED divides the display screen into a Prettyprint Region and an Interaction Region . The Prettyprint Region gives a prettyprinted view of the structure being edited; the Interaction Region contains the interaction between the user and INTERLISP's standard editor. DED's prettyprinter allows ellision, and the user may zoom in or out to see the expression being edited with more or less detail. There arc several arrow keys which allow the user to change quite easily the focus of attention in certain structural ways, as well as a menu-like facility for common command sequences. Together, these features provide a display-facility that considerably augments INTERLISP's otherwise quite sophisticated user interface . [Note : an extended version of this paper, a user's manual, and source files arc available from the author.","doi":null,"url":"https://ijcai.org/proceedings/1981/176","pdf":"https://ijcai.org/proceedings/1981/0176.pdf","markdown":"https://ijcai.org/proceedings/1981/176.md","bibtex":"https://ijcai.org/proceedings/1981/bibtex/176","volume":{"slug":"1981","title":"Proceedings of the Seventh International Joint Conference on Artificial Intelligence","short_title":"IJCAI 1981","url":"https://ijcai.org/proceedings/1981/","year":1981,"location":"Vancouver, British Columbia, Canada","dates":"24-28 August 1981","editors":"Roger C.
