Text editors designed for interactive use on visual display units offer significant advantages, particularly in simplicity of use, but non‐visual editors can provide facilities which are difficult to incorporate into a VDU editor without undermining these advantages. This paper describes a text editing system which offers both a visual and non‐visual mode of use, via two user interfaces to a common set of editing primitives, and allows the user to switch freely between modes during the course of an edit. The visual editing interface consists of a set of single‐key control functions which require no unusual VDU characteristics, while non‐visual editing is provided by a set of context editing commands which both duplicate these control functions and offer extra facilities, particularly for repetitive editing.
