Integrating hyperbolic functions

Is there a way to prevent Mathematica to turn a hyperbolic function (e.g.
Cosh) into exponentials?  I want to have:

	Integrate[Cosh[x],x]   ==> Sinh[x]

I tried to define an integration rule using Literal on the lhs, but then
when I input "Integrate[Cosh[x],x]", the Cosh is turned into exponentials
and therefore does not match the rule.  Is there a Quote in mathematica?
(Hold doesn't quite do the job either.) 

Any suggestion will be appreciated.
