EDT Editor Manual

This document is the EDT Editor Manual, a comprehensive reference guide for the DIGITAL EDT interactive text editor, version V3.00, published in September 1983. Intended for all users, from beginners to experienced, it covers the editor's functionality across various operating systems like VAX/VMS, RSTS/E, and RSX-11M/M-PLUS.

The manual introduces core EDT concepts, editing modes (keypad, line, nokeypad, and hardcopy change), and special features including an online HELP facility and a journal for session recovery. It details basic terminology, how to start and end editing sessions, and manage files. Key sections explain text manipulation such as entering, deleting, moving, copying, substituting, and replacing text. Advanced topics include defining custom keys, using macros, tab setting, and line numbering. Appendices provide information on EDT messages, command summaries, terminal support, and system-specific command qualifiers and file attributes for different operating environments.
