DEFINITION

Classification: 400/476

For actuating function key only:

(under subclass 473) Subject matter wherein said means causes only a function*-key* element to be pressed.

(1) Note. As discussed in the Glossary, section III, a function is an operation other than the impressing of a type-face* against a record-medium* to imprint a character*. The auxiliary mechanism of this subclass therefor causes pressing of, for example, a tabulator key, a backspace key, a line-space* key, etc.
