That keyboard chart that CapnScurvy alludes to in the "root" folder of the game. Stock allows you to rotate tube-to-tube in sequential order with the <W> key, and open or close the tubes with the <Q> key. In FotRSU, those are the same, other than the <W> only rotates through the bow tubes, while the <E> key will rotate through your aft tubes. Press the <Q> key anytime above approximately 100 feet, and you'll see the message "Opening Tube X" with the "X" signifying which ever tube happens to be selected at the time. Press the <W> key, and the selction moves to the next tube. Site your target, "aim", and then press the <Ctrl> key, and while holding it, press the <Enter> key (or click on the red Fire button), and you'll "shoot" a torp, if the door is open. Wait until you get the message "Torpedo in the water" before changing your course...
