What Mac said. Once the correct key shown on the main screen and notation match up, then you can change the key and the notes will also change if you pick that option. Although I play trumpet (Bb), I always make it a concert key. If you are worried, save each file with a different name as you go through the process. I use this feature all the time just to get the notation in the right key for my trumpet charts. After printing I just hit "Undo" and then hit Save.
