Hi Adrian, it all comes down to inherit from your keyboard/mouse
controller (Graphics Adapter, GA in OSG) and overwrite the parts you
want to change.

In your case, your GA is likely inheriting from OrbitManipulator, see

src/osgGA/OrbitManipulator::handleMouseWheel

Please have also a look to the osghangglide example, which has another
custom manipulator use case.
