I belief they are passive, at least I have not seen that you needed to activate them.

Not that I am aware of. In general air units can be moved over a larger distance on the strategy map and a zeppelin can cover a very large part of the map with its weapons.

It is WASD style. In addition when pressing the center mouse button you can rotate (left/right) or zoom in/out (forward/back) by moving the mouse.
