To change a setting globally, so that it affects all games, select **Options** and then select the tab containing the setting you would like to change.
To change a setting for just one game, highlight the game in the games list, then select **Edit Game** and select the tab containing the setting you would like to change. To make the game use the settings on that tab instead of the global settings tab, tick **Override global settings**.
See the :doc:`configuration file <../advanced_topics/configuration_file>` page for more information on how to do this. Configuration keys are listed in the Settings pages, after the description of each setting, in italics.
