If you are looking for a specific setting, but are not sure under which category it belongs, you can use the search function. Simply enter any text into the field at the top of the page and click the Search button. All settings that contain this text in their name will be displayed below and you can edit them directly. If the Search in description box is checked, the search will also return those settings that have the given text in their description (tooltip).
