You have to enable cheats by entering cheat in the Launch Options.  You just need those 5 letters, nothing else.  After you do that and start a game, you can activate the console by using the "~" key.

When you're in the console, you can enter help to get a list of all commands.  One such command is fowtrans.  To find out more about it you need to enter help fowtrans.  Using help with other commands will give you information about the other commands.

Note 1:  some commands take a while to execute, so wait for a response to appear before giving up.

Note 2:  all commands are lower case.

Exit the console with the Esc key or clicking on the X in the upper right of the console.
