This is a standard PC keyboard layout, so. That’s where things get confusing aka annoying: There is also a “Mac edition” – but it wasn’t available in Germany and costs about 50€ more than the standard edition, just for having USB ports and illuminated keys.
The BlackWidow keyboard has a PC layout (which I’ll call “PC edition”). It’s called a “gaming keyboard”, so after unpacking you’re official member of the “Cult of Razer”. “BlackWidow” is a mechanical keyboard for a reasonable price, lightyears better than the default apple keyboard. This is probably useful only to a few people – but if you are one of the mac users who bought a Razer BlackWidow keyboard (PC), this should be helpful.
