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.
