  We present a general method to identify an arbitrary number of fluctuating
quantities which satisfy a detailed fluctuation theorem for all times within
the framework of time-inhomogeneous Markovian jump processes. In doing so we
provide a unified perspective on many fluctuation theorems derived in the
literature. By complementing the stochastic dynamics with a thermodynamic
structure (i.e. using stochastic thermodynamics), we also express these
fluctuating quantities in terms of physical observables.
