  The symmetric spaces that appear as moduli spaces in string theory and
supergravity can be decomposed with explicit metrics using parabolic subgroups.
The resulting isometry between the original moduli space and this decomposition
can be used to find parametrizations of the moduli. One application is to
determine the volume parameter in conformal field moduli spaces for K3
surfaces. Other applications involve simple Dynkin diagram manipulations
inducing "going up and down" between symmetric spaces by adding parameters and
going to limits respectively. For supersymmetries such as N=6, this involves
combinatorics of less familiar "restricted" Dynkin diagrams.
