// It is FOUR_LEVEL with the exception that the fifth level

// If other modifiers are used, the Lock state is ignored.
// DETAILS ABOUT GERMAN:
// The capital form of ssharp (called sharp s) only exists for
// completely capitalized Text, not at the beginning of sentences
// or nouns (nouns have a captial letter at the beginning in german).
// The ssharp key, to the right of the zero key, takes this into
// account and has a questionmark mapped on shift-ssharp since
// normally no capital version is needed.
// When typing with active capsLock, this key type is needed to
// output two capital letters S because this is the only german key
// whose capital letter is not the same as the one typed with shift.
