They were not supported onVersion 7, BSD or System V implementations.  It is recommended thatany code depending on them be conditioned using NCURSES_VERSION..SH SEE ALSO\fBkeyok\fR(3X)..SH AUTHORThomas Dickey..\"#.\"# The following sets edit modes for GNU EMACS.\"# Local Variables:.\"# mode:nroff.\"# fill-column:79.\"# End:
