  12. How to Use:
  13. Press Shift+R to cycle through the tanks.
  14. Press Shift+Q to disable/enable the script.
  15. Press I to hide the dialog. (The script remains functional, though).
  16. Hold rightclick to activate . For best results, leave autofire off for a bit before doing so.
  17. If necessary, press Shift+M to re-calibrate the script. Wait for the ms to stabilise.
  18. Note: This calibration may break for Triple Twin, and is unnecessary for Streamliner.
