Hi FloB, Thanks for taking your time trying to assist me. Yes, I did read the manual, but it is very brief and doesn't really do a great job of explaining how to configure the keys. I don't know how to set keys for plugin-commands in general. I tried adding different keys in the ini-file (at least, that is what I thought I did), and I also made sure to remove them from the "standard" settings in X-Plane in order to avoid conflicts. However, it still didn't work. Thanks, Michael
