@6CIVILIZATION@1 When you've set a setter unit to work on, for instance, irrigation, click on the settler unit again and a box will appear in the centre of the screen with the settler unit having an `I' on it. Click anywhere in this box and the settler unit will start flashing. Press `I' again and repeat the process five times, and the squar will now be irrigated in the same turn. This also works for mining (10 turns) or roads (2 turns). This is incredibly useful especially on the two harder levels when you have to expand very quickly. In some of the earlier versions of the game you can press 1234567890T one after another to view a world map allowing you to look at the enemy cities.
