   This is a review of selected topics from recent work on symmetrycharges in asymptotically flat spacetime done by the author incollaboration with U. Kol and R. Javadinezhad. First we reinterpret thereality constraint on the boundary graviton as the gauge fixing of a newlocal symmetry, called dual supertranslations. This symmetry extends theBMS group and bears many similarities to the dual (magnetic) gaugesymmetry of electrodynamics. We use this new gauge symmetry to propose anew description of the TAUB-NUT space that does not contain closedtime-like curves. Next we summarize progress towards the definition ofLorentz and super-Lorentz charges that commute with supertranslationsand with the soft graviton mode.
