request for the soft key [copy]

[compsystems]

the soft key [copy] must copy the expressions in parentheses.

example, simplify: MAXIMUM

x^3+6 [enter] x^3+6
x[x^2]*Ans [enter] x^5+6*x^2 OK
Ans==[Shift]+[+]

current firmware:

x^3+6 [enter] x^3+6
x[x^2]* [up] [copy] x^2*x^3+6 [enter] x^5+6 =(
[up] [copy] == (copy ans)

next firmware:

x^3+6 [enter] x^3+6
x[x^2]* [up] [copy] x^2*(x^3+6) [enter] x^5+6*x^2 OK

since the system must be consistent with ANS, you agree?
