  A detailed Faddeev-Jackiw quantization of an Abelian and non-Abelian exotic
action for gravity in three dimensions is performed. We obtain for the theories
under study the constraints, the gauge transformations, the generalized
Faddeev-Jackiw brackets and we perform the counting of physical degrees of
freedom. In addition, we compare our results with those found in the literature
where the canonical analysis is developed, in particular, we show that both the
generalized Faddeev-Jackiw brackets and Dirac's brackets coincide to each
other. Finally we discuss some remarks and prospects.
