 .SH DESCRIPTION
 The function \fBset_current_item\fR sets the current item (the item on which
-the menu cursor is positioned).  \fBcurrent_item\fR returns a pointer to the

+\fBcurrent_item\fR returns a pointer to the
 current item in the given menu.
 .PP
 The function \fBset_top_row\fR sets the top row of the menu to show the given
 row (the top row is initially 0, and is reset to this value whenever the
-\fBO_ROWMAJOR\fR option is toggled).  The item leftmost on the given row
-becomes current.  The function \fBtop_row\fR returns the number of the top menu
+\fBO_ROWMAJOR\fR option is toggled).
+The item leftmost on the given row

+The function \fBtop_row\fR returns the number of the top menu
 row being displayed.
 .PP
 The function \fBitem_index\fR returns the (zero-origin) index of \fIitem\fR in
 the menu's item pointer list.
 .SH RETURN VALUE
 \fBcurrent_item\fR returns a pointer (which may be \fBNULL\fR).

 error value) if their \fImenu\fP parameter is \fBNULL\fP.
