Well first off welcome to Combatace,I hope you come by and enjoy the company.Now as for your keyboard...to be honest I changed mine and use my hotas,you might try to remap them to what ever you feel comfortable with,the reason I skated answering your question directly is I don't have a clue how that happened.
I think the training missions have a pre selected aircraft for your training.In the campain besure to check the different squadrons before choosing as they have different models and different specialties.
I'll see what I can come up with for you on the keyboard,gotta be someone here who might know.
Oh yeah..is the Navy handing out flyers?It seems we're getting over run with Navy types lately,before long I'm going to end up being the only Devil Dog around!
