SUMMARY
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. Now you do not have to remove your handfrom the joystick to press the letter "g". Instead, you can accomplish thisby pressing button two on the joystick. The joystick filter detects thisand the keyboard filter pushes the "g" onto the keyboard buffer.
