The German E1 keyboard layout is an extension to the German basic layout
containing a complete set of letters for all European languages. It comes with
a set of dead keys giving access to all imaginable accents. My verdict after
having tested the layout for some months now: this is the keyboard for Latin
based languages! Beyond the specific case-related benefits arising out of its
universal design, I don't expect to it proliferate widely, because it privileges
the characters “äöüß” that are mostly used in German. Also the disposition of
the letter “z” in the upper QWERTZ row, will discourage many people used to the
QWERTY design. Computer programmers also, usually prefer the US keyboard
because many common keyboard shortcuts are tailored for this design.
A part from that, a national keyboard layout is also expression of the writing
culture of a country. In this regard it is particularly disappointing that this
honorable new norm ships gender ideology.
