Joyflt.exe is a driver that represents two filter drivers in one. The firstdriver sits on top of the joystick driver and examines the data returned bythe joystick driver. The second filter sits on top of the keyboard classdriver. If the filter detects that a button has been pressed, it adds theappropriate raw keystroke to the keyboard buffer.
For example, pressing button two on the joystick adds the letter "g" to thekeyboard buffer. In a flight simulation, the letter "g" is often used toraise and lower the landing gear.
