You should be able to do it in regular (non-vertex-editing) mode as well... except that will snap the vertex (vertices, if there's one or more below it) to the grid of the ortho view you're using, and the rest of the brush will shift over.
Note that this doesn't in any way mean that all eight corners of a cube, for instance, will gridsnap. But if your brush is a size that works with the grid (ie appropriate powers of 2) then it basically will.
