How to enable mouse in FB?

[Robi]

Hello folks!
This is my first post here.

Can someone please tell me how to enable the mouse in order to use the mouse to move and fire the machinegun of the rear gunner, while TrackIR is enabled for view?
What setting do I have to make in conf.ini?
Thank you in advance.

In IL2 controls, map Toggle Level Autopilot and turn it on. Now you can use all the guns with the mouse in a bomber.
