It works with the Canadian multilingual standard keyboard. 
Thank you

Thanks for figuring this out! I don't have a sweedish keyboard to test this on, so I wonder if one of you can help me by applying the patch below (just a simple change to two lines), exiting drscheme, running "setup-plt" from a shell/command window and then seeing if DrScheme behaves properly after that?

The file in question in plt/collects/framework/private/keymap.ss. Just in case you're not familiar with the notation below, the lines with the "-" in front go away and should be replaced by the ones with the "+" in front (but don't include the "+" itself). The lines without "+"
or "-" are just there for context so you can be sure you're in the right spot in the file.
