First, go to the following folder:
(your disk drive)\steam\steamapps\common\il-2 Sturmovik Cliffs of Dover\manual
In there you will find six .PDF files, each one containing the manual in a different language. Open whichever one suits your language knowledge best.
Then, you need to take a look at the sections:
- Options - controls (page 20 in the English manual)
- Camera settings (page 25 in the English manual)
- Flying the planes - Gunner controls (page 77 in the English manual)
This will tell you everything you need to know
