German Keyboard Layout
The German alphabet is the same as English, with the addiction of the following:
The ß is called Eszett (sz) or scharfes S, sharp s. It is officially considered distinct letters of the alphabet.
Here's Germany layout.
Those special letters ä ö ü ß, does not occur often. Their frequency ranks near the bottom.
You can see that, the German layout is not very efficient.
• It is based on the inefficient QWERTY layout.
• The special characters ä ö ü ß, each has a dedicated key. It's a waste of key spots. It would be better, if the key to the right of L is a dead key for DIAERESIS ¨
