I switched to a physical Swedish/Finnish keyboard to save my sanity (too many ä and ö I need to type), but I noticed many symbols are poorly documented, and do not match the equivalent Windows keyboard. For instance, the symbols | and \ are not where a Windows keyboard puts them (and also, the Windows keyboard does show where these symbols are). Same is for [] and {}. I looked online for a quick guide of where the symbols are in an Apple Swedish/Finnish keyboard, but I am still to find one. I thought Apple would provide it, but I failed to find it.
Does anybody has a list or a picture showing all the symbols one can produce with Option and Option + Shift?
