When gauging a (d-1)-form symmetry in d spacetime dimensions, one formally expects the gauged theory to carry a dual -1-form symmetry. This work focuses on the study of such symmetries, in particular via the spacetime-filling topological operators that implement them, in two-dimensional field theory (with an eye towards general quantum field theory). As theories with (d-1)-form symmetries are known to be equivalent to direct sums of local theories, we review how gauging a (d-1)-form symmetry projects onto a single component in this sum, and explain how gauging the resulting -1-form symmetry restores the direct sum.
