The problem: I am using the US keyboard layout on all my laptops (lot of stuff is better acessible). The problem emerge if you have to do some corresponce for your daily business and need the special chars of the german language.
To make these caracters accessible by shortcuts, do the following:
- change your keboard laout to United States -Internation layout
- enter the characters!
- ä/Ä by Right Alt (+ Shift) + q
- ö/Ö by Right Alt (+ Shift) + p
- ü/Ü by Right Alt (+ Shift) + y
Or lot of other characters as shown here.
