 .SH DESCRIPTION
-The \fBscroll\fR routine scrolls the window up one line.
+The \fBscroll\fP routine scrolls the window up one line.
 This involves moving
 the lines in the window data structure.
 As an optimization, if the scrolling
 region of the window is the entire screen,
 the \fIphysical screen\fP may be scrolled at the same time.
 .PP
-For positive \fIn\fR, the \fBscrl\fR and \fBwscrl\fR routines scroll the
-window up \fIn\fR lines (line \fIi\fR+\fIn\fR becomes \fIi\fR); otherwise
-scroll the window down \fIn\fR lines.

 This involves moving the lines in the
 window character image structure.
 The current cursor position is not changed.
