How do you input cheats on this game? I like to use them getting started on open ended games but I can't figure out how to get them in

I don't know if you figured this out or not yet but from what I gathered you just start your mission and simply type the cheat in. Heres a list of the cheats:
MAGICEYE = reveal map
LOLLY = max lollypops
JUICE = max mushroom juice
CHOCO = max chocolate cake
WARTIME = max weapons
IAMHUNGRY = max food
IRONMAN = max iron
STONEMASON = max stone
LUMBERJACK = max lumber
RAIN = max maggot
CASHCOW = get 5000 money
WINNER = loose mission
