I am working with keysyms of a Linux Keyboard and need to consider the following rule:
The Shift modifier is off, and the Lock modifier is on and is interpreted as CapsLock. In this case, the first KeySym is used, but if that KeySym is lowercase alphabetic, then the corresponding uppercase KeySym is used instead.
On a Keyboard I might have Ä-ä, Ö-ö, Ü-ü on a German Keyboard or ù-% on a French keyboard.
- what is the definition of an alphabetic key?
- Are ä , ö, ü, ù considered lowercase alphabetic?
- Is an alphabetic key only a-z, A-Z or are the special characters (ä , ö, ü, ù ) included?
