Assign 'sincos' into a key in the User mode

Im using the function on cas command line

Code:

#cas
ss(x):=(subst(x,exp,cosh+sinh));simplify(sincos(x))
#end

It use a substitution for real exp and sincos function for complex exp

Code:

ss((e^x-e^(-x))/2)
Gives
sinh(x)

And

Code:

ss(1/2*((-(i))*e^(i*x)+i*e^((-(i))*x)))
Gives
sin(x)

Simplification set to maximum
Still, it would be better built in.
