Word processor and display
First Claim
1. A word processor comprising:
- input means including a keyboard with a plurality of keys associated with different graphic or function including at least two cursor control keys, said input means producing a unique key code for each key or group of keys,display means including a cathode ray tube for producing a visible image in response to a periodically repeating video signal and associated horizontal and vertical sync signals, said visible image including a cursor positioned in response to actuation of said cursor control keys,control means responsive to said input means for manipulating and storing said unique key codes and for controlling said display means,wherein the improvement comprises;
word underscore means in said control means responsive to one of said unique key codes for storing an underscore representation associated with each character of a word identified by the position of said cursor when said unique keycode is sensed.

Abstract
A word processor supports two display modes, one unformatted mode comprising display of a partial page and another formatted mode displaying format of an entire page of text. Both modes impose minimal burden on the display allowing use, for example, of standard display chips with a variety of monitors including a standard TV set or TV monitor. Other advanced functions include simple addition, movement and deletion of text units or blocks; simplified underscore, underscore deletion, word underscore and word underscore deletion; and an uncluttered insert display regardless of the extent of inserted text. The hyphenate function is improved by informing the operator, via the display, of the relation between, not only the right margin and the hyphenate candidate, but also the relation between the hyphenate candidate and the actual preceding line endings.
