Hidden settings

Factorio supports a number of hidden configuration options that are not normally shown in the GUI. They can be accessed by holding CTRL + ALT when clicking the "Settings" button in the pause menu, which will cause a new button labeled "The rest" to appear.

Most of these settings are also in the "config.ini" file in the Factorio user data directory.

These settings may be experimental and may not be validated for safety, so change them at your own risk.
