Pete,
This question has also been on my mind for some time, but I think you have answered it.
I was wondering if the PREV and NEXT buttons in the FS Navigator could be activated by an external button through FSUIPC, just as is possible with FLY PLAN in the same program by assigning a key to that function. I realise that these are not directly Flight Sim Commands and that is what makes the difference. We need to get the code changed in FS Navigator I guess.
We have become so used to the idea that you can do anything with FSUIPC, don't be surprised when we wonder why it can't do something that appears simple to us idiots.
Great Program,
Regards
