+The function \fBset_current_field\fR sets the current field of the given
 form; \fBcurrent_field\fR returns the current field of the given form.
 .PP
+The function \fBunfocus_current_field\fR removes the focus from the current
+field of the form.
+In such state, inquiries via \fBcurrent_field\fR shall return a NULL pointer.

 The function \fBset_form_page\fR sets the form's page number (goes to page
 \fIn\fR of the form).
 .PP
 The function \fBform_page\fR returns the form's current page number.

 The function \fBfield_index\fR returns the index of the field in the
-field array of the form it is connected to. It returns \fBERR\fR if

+It returns \fBERR\fR if
 the argument is the null pointer or the field is not connected.
