Abstract
On electronic typewriters which have the ability to record into a small working memory those characters, functions and escapements which are keyed at the keyboard, it is many times advantageous to be able to place the carrier and the print point over a character which has been previously typed without using repeated backspaces. Disclosed herein is a feature for an electronic typewriter which permits the operator to easily align the print point with a character on the page by positioning a reference mark on the card holder or print carrier in relation to a previously printed character and then through keyboard control cause the carriage to shift its position such that the print point is then exactly aligned with the character printed. The positioning of the carrier such that the reference mark is in relation to the desired print point is accomplished by a backspace operation and the repositioning or causing of the carrier to assume a position immediately over the subject character is accomplished by keyboard control through the electronics of the typewriter to cause the carrier to shift a predetermined distance.
