Abstract: A forms format program is read from pre-printed markings on a typing form to assist the operator in moving accurately and quickly to different typing fields. Depression of the tabulation key can select tabulation to a form selected tab stop, vertical feed and automatic line return. A field return key generates new lines within a column defined by form selected tab stops. Marks on a typing form can both initiate and terminate repeat forward or reverse indexing to provide a search for a new vertically displaced typing field. Typing status functions such as single or double line spacing are automatically selected by markings on the form.
