Using ‘anyway’ to indicate that the previous matter was an aside, or it doesn’t affect the conclusion, for instance, to say: “It was wet and nobody was at the park. Anyway, I went home.”
Could you use Tamen? "Nevertheless/however" seem to have a bit more of a concessive feel to it, but I feel it works largely the same way. It has the effect of moving past whatever objection or interruption preceded it, which is basically how "anyway" works.
I feel both have the function of "getting back on topic."
