This is my struggle living in Sweden as an American. I go to type on my coworkers keyboard and the result is a mixuture of frustration and hilarity as my muscle memory produces bad results. Some things make absolutely no sense like switching - and _ on Swedish keyboards. Other random frustration is the lack of tilde on Swedish keyboards. How can you work on Unix based systems without easy access to tilde?!
Interestingly all the Swedes I work with have their own solutions to the tilde problem. Some type the alt code while others use alternative keyboard configurations.
Tilde is available with alt-carret/umlaut, that's no harder then other specials such as @[]{}() etc.
But I understand the frustration, I feel the same every time you boot up a new system or VM and it defaults to american layout, changing the keyboard layout from a unix prompt when you can't find i.e. - / : = is surprisingly hard.
I used to use svorak a5 about 10 years ago but eventually switched back to swedish qwerty since it was causing such confusion with coworkers.
I also switch to a right-handed mouse about 4-5 years ago for the same reason with the addition that ergonomic left handed mice are pretty much non-existent, it's mainly just standard two button mice which you flip the mouse buttons on.
