-.PP
-The \fBsubpad\fP routine creates and returns a pointer to a subwindow within a
-pad with the given number of lines, \fInlines\fP, and columns, \fIncols\fP.
-Unlike \fBsubwin\fP, which uses screen coordinates, the window is at position
-(\fIbegin\fR_\fIx\fB,\fR \fIbegin\fR_\fIy\fR) on the pad.
-The window is
-made in the middle of the window \fIorig\fP, so that changes made to one window
-affect both windows.
-During the use of this routine, it will often be
-necessary to call \fBtouchwin\fP or \fBtouchline\fP on \fIorig\fP before
-calling \fBprefresh\fP.
-.SS prefresh, pnoutrefresh
-.PP
-The \fBprefresh\fP and \fBpnoutrefresh\fP routines are analogous to
-\fBwrefresh\fP and \fBwnoutrefresh\fP except that they relate to pads instead
-of windows.
-The additional parameters are needed to indicate what part of the
-pad and screen are involved.
+.B \%subpad
+creates and returns a pointer to a subwindow within a pad
+with the given number of lines,
+.IR nlines ,
+and columns,
+.IR ncols .
+Unlike \fB\%subwin\fP(3X),
+which uses screen coordinates,
+the new pad is placed at position
+.RI ( begin_y ,
+.IR begin_x )
+relative to its parent.
+Thus,
+changes made to one pad can affect both.
+When operating on a subpad,
+it is often necessary to call \fB\%touchwin\fP(3X) or
+\fB\%touchline\fP(3X) on
+.I parent
+before calling
+.BR \%prefresh .
+.SS "prefresh, pnoutrefresh"
+.B \%prefresh\fP
+and
+.B \%pnoutrefresh
+are analogous to \fB\%wrefresh\fP(3X) and \fB\%wnoutrefresh\fP(3X)
+except that they operate on pads rather than windows.
+They require additional parameters are needed to indicate what portions
+of the pad and screen are involved.
