-The \fBscrollok\fR option controls what happens when the cursor of a window is
-moved off the edge of the window or scrolling region, either as a result of a
-newline action on the bottom line, or typing the last character of the last
-line.
-If disabled, (\fIbf\fR is \fBFALSE\fR), the cursor is left on the bottom
-line.
-If enabled, (\fIbf\fR is \fBTRUE\fR), the window is scrolled up one line
-(Note that to get the physical scrolling effect on the terminal, it is
-also necessary to call \fBidlok\fR).
-.PP
-The \fBnl\fR and \fBnonl\fR routines control whether the underlying display
-device translates the return key into newline on input, and whether it
-translates newline into return and line-feed on output (in either case, the
-call \fBaddch('\\n')\fR does the equivalent of return and line feed on the
-virtual screen).
-Initially, these translations do occur.
-If you disable them
-using \fBnonl\fR, \fBcurses\fR will be able to make better use of the line-feed
-capability, resulting in faster cursor motion.
-Also, \fBcurses\fR will then be
-able to detect the return key.
