rawkey-class description strings containing Amiga/RAmiga/LAmiga not working under AmigaOS2.0?

Problem:
- rawkey-class input filter description strings containing Amiga/RAmiga/LAmiga do not work under AmigaOS2.0
- CxFilter() fails when using such a rawkey-class input filter description string

Possible reasons:
because the Amiga keys are called "Command" in OS versions below 3.

Possible solutions:
Use "Command"/"LCommand"/"RCommand" instead of "Amiga"/"LAmiga"/"RAmiga".
