  Redshift drift is the phenomenon whereby the observed redshift between an
emitter and observer comoving with the Hubble flow in an expanding FLRW
universe will slowly evolve -- on a timescale comparable to the Hubble time.
There are nevertheless serious astrometric proposals for actually observing
this effect. We shall however pursue a more abstract theoretical goal, and
perform a general cosmographic analysis of this effect, eschewing (for now)
dynamical considerations in favour of purely kinematic symmetry considerations
and Taylor series expansions based on FLRW spacetimes. We shall develop various
exact results and series expansions for the redshift drift (and its derivative)
in terms of the present day Hubble, deceleration, jerk, snap, crackle, and pop
parameters, as well as the present day redshift of the source. In particular,
potential observation of this redshift drift effect is intimately related to
the universe exhibiting a nonzero deceleration parameter.
