Mouse controlled functions: There are three mouse modi. In the usual mode (pointer cursor) panel's controls can be operated with the mouse. To change a control, click with the left/middle mouse button on the corresponding knob/lever. While the left mouse button leads to small increments/decrements, the middle one makes greater ones. Clicking on the left hand site of the knob/lever decreases the value, while clicking on the right hand side increases it.

Right clicking the mouse activates the simulator control mode (cross hair cursor). This allows control of aileron/elevator via the mouse in absence of a joystick (enable --enable-auto-coordination in this case).

Right clicking the mouse another time activates the view control mode (arrow cursor). This allows changing direction of view via the mouse.

Right clicking the mouse once more resets it into the initial state.
