You will probably also often want to design your items differently for questions in literature and differently for questions related to the maths. To help you keep different subjects separate, SuperMemo introduces the concept of a category . A category is a section of knowledge tree in the contents window . It is used for keeping material related to a single subject. Elements added to a given category may use their own template that determines the appearance of particular components , colors, fonts, sizes of images, number of sound components, etc.
Categories can be helpful in managing a large number of categories.
Default template can be changed by typing in the new name or by double clicking the template field and selecting a new template from the template registry . Create new category , Make hook , and Make root . To create a new category, you will most likely want to use Create new category on the pop-up menu in the contents window . Also to determine the root and hook you will rather use Make hook and Make root on the same menu. To select a category, you have to choose it in the category combo box on the main toolbar.
