DECLARE
TEMP varchar2 ( 15 ) ;
BEGIN
TEMP := :ITEM7 ;
:ITEM7 :=:ITEM5 ;
:ITEM5 :=TEMP;
END;

I AM USING COPY BUTTON TRIGGER
BEGIN
     go_item('item1');
     :v_value :=:system.current_value;
     :v_curr_field :=:system.current_item;
END;
I AM USING PASTE BUTTON TRIGGER
DECLARE
BEGIN
:ITEM1:=:V_VALUE;
END;
