1 Introduction

Hemlock is a text editor which follows in the tradition of Emacs and the Lisp Machine editor ZWEI. In its basic form, Hemlock has almost the same command set as ITS/TOPS-20 Emacs¹, and similar features such as multiple windows and extended commands, as well as built in documentation features. The reader should bear in mind that whenever some powerful feature of Hemlock is described, it has probably been directly inspired by Emacs.

This manual describes Hemlock’s commands and other user visible features and then goes on to tell how to make simple customizations. For complete documentation of the Hemlock primitives with which commands are written, the Hemlock Command Implementor’s Manual is also available.
