In-application window switching is extremely time-saving and convenient. Problem is the default mapping doesn't work with Swedish keyboard. I choose to use English on my Mac, and maybe that's why the region setting doesn't really get it entirely right. Well, either way it's quite painless to fix. Open "System Preferences..." click on "Keyboard" and the "Keyboard Shortcuts" tab. Then make sure the setting is as above. You need to double-click the shortcut (right column) and press the key combination you want.
