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

.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

+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).
