Hmm, you have only posted twice and that is for the 2 exact topics you must have accidentally made. If you are still checking this you can try to press the period key for the brake. F2 i think is to puch in the throttle, F1 is to lower it and F3 is to make the aircraft go as fast as possible. Full throttle. You can try the download section, may be in miscellanious section or essentials. Someone uploaded a whole list of the FS commads in wordpad or notepad. If you get it print it.

The best you can do is run a search on FS keyboard commands.......

just did the search

second download from top down. The 4th too. Just keep looking.

I strongly suggest you buy a joystick. At least the throttle, brakes, flaps, kneeboard and other re-assignable key ( <<was that even a word?) can be changed. Hope that helps
