Tides of War

I recently bought Enigma and downloaded the two patches for the US version. I am still struggling with the controls, though I have played the sub campaign through mission 8, albeit without the patches. Is there an online Manual or help file which systematically goes through the controls? This would be very helpful. I see that with the patches the game is quite different. Any suggestions would be appreciated. Thanks.

I'm running the original US version patched to the Gold edition.

In my ERT folder there's file ENIGMA.pdf. I'm pretty sure it's on the CD as well. This is the SHIP OPERATIONS MANUAL. What else do you need?

Use F1 F2 F3 F4 in game
