Thanks for the further info 300hp.GT. I hadn't got that far.
Here is the reply I received from Carenado: -
"Greetings,
The shortcut keys are calling simulator's input and codes, in order to have more realistic systems, avionics and behaviour, we had to overwrite most of those input and codes and they have to be input on the screen.
Regards,
Carenado"
Very disappointing that they removed the ability to use simple keyboard shortcuts. They should either offer a demo so you can test the functionality or at least warn people that you cannot use them. Telling customers on their website there is very little 2d panels does not cover this scenario.
That's it for me. I will NEVER purchase nor recommend a Carenado product again.
