How do I raise landing gear FSX?

Well first things first, you need a keyboard. If you do have a keyboard by you and is connected to your own personal computer in which is running Microsoft Flight Simulator X: Steam Edition, search for the key (or button) that shows the letter 'G'. Press that key for a very short amount of time, then release it. As you will observe in the Microsoft Flight Simulator X: Steam Edition window, you will see your gear indicator change lights meaning your gear is retracting.
