PS/2 keyboards:
0000041D Swedish *3 (I would prefer 0000083B Swedish with Sami to the degree that can be implemented with ISO8859-15 characters.)
00000409 US *2 (I would prefer
EurKEY, but US International with AltGr dead keys is OK.)
Below keyboards work only in emulators, unless an adapter works:
USB keyboards:
00000809 United Kingdom (I would like a layout similar to EurKEY.)
00000406 Danish
Bluetooth keyboard:
Nordic layout i.e. these on top of each other, but with different colors where there is conflict:
00000414 Norwegian (I think the Norwegian layout is best among the Nordic since it has | and \ easily accessible.)
00000406 Danish
0000041D Swedish
0000040B Finnish (Same as Swedish.)
I have another bluetooth keyboard:
00000409 US, but with Å Ä Ö also printed on [ ' ; and that is supported in Linux ("Swedish - Swedish (US, with Swedish letters)").
I have laptops with Nordic layout; also for emulator use.
