It shouldn't really be all that bad; it's just two letters that differ -- both in actual font design and keyboard placement. Swedish and Finnish write the letters Ö and Ä; in Danish and Norwegian they're Æ and Ø. The really weird thing is that the latter swap places between the languages; in Danish the keys are Æ to the left, Ø to the right; in Norwegian it's the other way around. So we have these two keys to the right of L that are marked, respectively, ØÖÆ and ÆÄØ. Fortunately, the Å key seems to be the same for all four languages, and stay put in the row above the aforementioned ones, to the right of P.
