  String theories inspire a new formalism for their low-energy limits. In this
approach to these field theories, spacetime duality and stringy left/right
handedness are manifest. Enlarged tangent-space symmetries allow the different
fields (graviton, axion, Yang-Mills) to be treated as a single multiplet, even
in the bosonic case, except for the dilaton (multiplet), which appears as the
measure. (Based on a talk given at Strings '93, May 24-29, Berkeley, CA. A
section added after the talk discusses modifications for nonabelian
Yang-Mills.)
