        CASE "NEXT" 
            IF tbvSelect.Row < tbvSelect.Rows.Count - 1 THEN 
                tbvSelect.MoveTo(tbvSelect.Row + 1, tbvSelect.Column) 
            ENDIF 
        CASE "BACK" 
            IF tbvSelect.Row > 0 THEN 
                tbvSelect.MoveTo(tbvSelect.Row - 1, tbvSelect.Column) 
            ENDIF
