Configuration
The configuring is realized in the systemconfiguration.ini configuration file in the section
[keyconfiguration]. Each line defines what is known as a hardkey event. A hardkey event is
the n-th actuation of a specific hardkey. For example, the second and third actuation of a
specific hardkey can result in different responses.
The entries in the systemconfiguration.ini configuration file can be overwritten with user-
specific settings. The directories
are available for this purpose.
