Please take a look into Calamus' SYSTEM folder. You will find some Windows stuff in there. Try KEYGET.EXE and note down the scan codes which you get when pressing â, Â, etc.
Then open keytab.ini and try and understand the syntax. You will find out how to change the contents in order to get your special Swedish characters from keyboard to Calamus.
Maybe a look at the Norwegian file, keytab_NO.ini, is a good help for you. (The valid file has to be named keytab.ini, anyway.)
