The Item Bank Configuration page opens the Configuration tab by default, which allows you to specify font settings for math equations and language settings for items. It also allows you to specify the AutoCorrect text settings used in the Rich Text editor, via the Auto-Correct tab. You can also add new analysis groups to the Item Bank via the Analysis Group tab. These settings apply to all the projects under the Item Bank.
This page can be reached by navigating to Manage Item Bank → Configuration.
