The document provides recommendations for command dialogues used to accomplish typical office tasks. Command dialogues are sequences of instructions provided by the user to the system which, when processed, result in associated system actions. Users input (from recall, rather than selecting from a menu) complete or abbreviated command phrases (e.g. mnemonics, letters, function keys, hot keys) in the order required by the command language syntax and the computer performs the activities initiated by the command(s) and their associated parameters.
