Using developer mode
Once enabled, the developer menu is opened by pressing Template:Key press. The Simulation tab contains various cheats such as instant zone development, disabling pollution, or disabling the need for services. Spawning events and disasters requires selecting a building beforehand. Checking "bypass validation results" disables checks before placing buildings and networks and can be used to create quays easier closer to the waterline.
The add object menu is opened by pressing Template:Key press. It lets you access many more objects than those available through the default user interface. Adding moving objects like cars or cims is likely to cause problems.
