Creating a New Superclass
~~~~~~~~~~~~~~~~~~~~~~~~~

In the taxonomy window, click to highlight **Person**. Tables for identifier **Person** show up in the editing window. Click the **Add a superclass to the class** button to the left of the **Superclasses** table label, as shown in :numref:`figure-KB-Editor-add-superclass-button.png`.

After clicking the **Add a superclass to the class** button, a new row appears in the **Superclasses** table. At the same time, 2 new buttons appear to the left of the new row, a **green check mark** for saving the edit and a **red forbidden sign** for canceling. A pull-down menu is available for making a selection from classes which exist in the KB.

Click in the first field of the new row to enable it for edit. Type in Hominoid. After typing, click the **green check mark** to save the edit. **Hominoid** now appears in the taxonomy window under **Classes**. Expand **Hominoid**. The taxonomy tree now shows **Person** is a subclass of **Hominoid**, as seen in :numref:`figure-KB-Editor-superclass-saved.png`. At the same time, in the **Text Editor**, **Hominoid** is added to family.flr as a superclass of **Person**.  Note that there is now an * in the family.flr tab, indicating that there are unsaved edits made to the file.  To permanently add superclass **Hominoid** to family.flr, the file must be saved explicitly.
