My workaround for this, working on Swedish keyboards in the English version of Dorico on Windows, is installing English as an additional language with its corresponding keyboard layout and switching to the English keyboard layout when working with Dorico by using the Windows specific Win+spacebar key command. This allows me to use the thought-out predefined key commands by the Dorico team where the keys have the same positions as those which the default key commands were designed to work with. Of course this means that I would have to learn the deviations between the Swedish layout and the English layout by heart, but after using Dorico regularly for not that terribly long, this knowledge kind of stuck automatically.
