ABSTRACT:
In a keyboard with a restricted number of input keys, shifting between upper-case and lower-case character letters is effected with a key which is otherwise available for character or symbol entry. The upper case shift is accomplished by actuating a control element while observing a particular timing condition. Toggling the control element allows for comfortable caps shifting.
