I'm a Finn, and Finnish language uses often accented characters, like ä and ö. I can produce them from Multikey using stylus, but that is slow method if you are working from keyboard. In /etc/keymap-2.6.map are lines like "compose '~' 'a' to 'ä'", but I could not find how to combine ~ and a, and get ä, for example.
This is the only bigger problem, otherwise I'm very happy user of OZ 18.104.22.168-alpha/SL-C3100. Opie looks great. Thanks guys!
