This German keyboard layout differs from QWERTY not only in the switching of Z and Y, but also in the layout of most of the special characters, which are switched around to accomodate the umlauts which are part of the German language. Unfortunately, this means that many characters that are important for programming, especially the various braces are much more awkward to type than on the QWERTY layout.
