Welcome, Bjørn! I'm in the same general area. The Eastern Sierra is my favorite place to photograph, especially in fall and winter.
As for the "ø" character, I can't seem to produce it using the method suggested here. I've just been copying and pasting over the years, though it's possible I may have forgotten once or twice and mindlessly substituted an "o" in someone's name.
A higher priority for me than a Scandinavian keyboard, or a Spanish one (with the ñ character and accent marks), is one just like the one on my laptop, with the page up and page down keys side-by-side to allow easy toggling instead of being stacked. This is much more convenient- human fingers are side-by-side, not arranged vertically!
