Key-controlled method for invoking automatic row and column addition in an interactive text processing system
First Claim
1. In an interactive text processing system having a display screen including a positionable cursor, a microprocessor including a memory, and an accumulator, and a keyboard to permit entry of data and control information into said system by an operator interactively, an improved method for assisting said operator in adding a plurality of numbers which are displayed in sequential positions on said display screen, said numbers being stored in said memory at memory locations which can be determined in accordance with the displayed position of said cursor on said screen, said method comprising the steps of said operator:
- a. positioning said cursor on said screen adjacent the first number of said plurality to be added;
b. positioning and holding one key which has been pre-programmed for a predetermined function to cause said processor to;
(1) add said first number to a number stored in said accumulator to define a subtotal which is stored in said accumulator,(2) step said cursor to said next number in said sequential positions to cause said system to develop a new said subtotal, and(3) repeat steps (1) and (2) for each said number in said sequence until said one key is released; and
c. releasing said one key when said cursor is moved adjacent to said last number of said plurality in said sequence whereby the typamatic operation of said one key causes said numbers in said sequence to be sequentially added to said accumulator as long as said one key is held depressed.

Abstract
A method is disclosed for assisting the operator of an interactive text processing system to add a list of numbers that have been entered into the system during the creation of a document. The method involves the operator positioning the cursor adjacent the first number in the sequence by operating the cursor move keys. The next step involves the operator pressing and holding either the "column add" or the "row add" function key while watching the movement of the cursor from the first number in the sequence to succeeding numbers in the sequence until the cursor is positioned adjacent the last number in the sequence, at which time the function key is released. The last step in the process is for the operator to press the Enter key which enters the total into the system for subsequent processing and displays the total in the appropriate location on the display. The provision in the system for the operator to total a sequence of displayed numbers by means of a function key which is made typamatic greatly enhances operator efficiency and system throughput.
