Does - margins, dydx(_all) - also handle the interaction of two dummy variables?

Yes. ht (hypertension, yes/no) and smoke (yes/no) are such, and interacted in the model below. Notice that each has a positive main effect on low bw, but if they appear together the effect is, strangely enough, reduced (although the negative interaction coefficient is not distinguishable from zero).
