Usually when I am using Bugsier 2, I use almost only keyboard, with the shift key for precision. I don't know if you guys know, but you can use the numerical keyboard to control individually the azipods.
The 7 and 1 keys, controls the port azipod, 4 resets it.
The 9 and 3 keys, controls the starboard azipod, 6 resets it.
Press 5 and it will reset all the azipods to neutral.
This only controls the rotation speed, not the angle, which means that you can only increase or decrease speed.
Pressing shift and one of the numbers, you can increase speed with precision, a small amount at a time.
