Abstract

In sophisticated word processor systems, it would be desirable to keep the number of keys for mode selection to a minimum and also, to eliminate the need to have lighted keys or some other method of continuous indication to the operator to indicate the mode in which the system was presently operating.

In sophisticated word processor systems, it would be desirable to keep the number of keys for mode selection to a minimum and also, to eliminate the need to have lighted keys or some other method of continuous indication to the operator to indicate the mode in which the system was presently operating.

Normally, a system will operate in different modes. For instance, in most systems if the operator wanted to print a line, the operator would select "Print" and that mode would be active and indicated in some way to the operator. Then the operator would depress llLinell to print a line. If the operator wanted to delete a line, the operator would select mode, which would again have to be indicated to the operator that this mode was active. The operator would then need to select "Line".

A concept is disclosed whereby the number of keys for mode selection is kept to a minimum and the need to provide a continuous indication of the mode to the operator is eliminated. The proposed concept would provide a system that continually monitored which keys are held depressed. That is possible by using keys which provide an output code on the downstroke of the key ana also provide a code on the upstroke of the keys. If the operator desires to delete a line or print a line, the operator holds the appropriate key depressed while depressing the modifier ke...
