n(th) Derivatives of unknown Functions

Hi,

Consider F to be an unknown function. I would like to solve

d^s / dx^k F[2 x - a]

(a is a constant, F a function with real numbers as input and real
numbers as output, (no vectors)).

With
D[ F[2 x - a], {x, s} ]
as Mma-Input I don't get the result
(s)
2^s F [2 x - a]

Is there any way to work around? Thanks for an answer!
