A dialog box pops up asking for the name of the new subclass to be created. A pull-down menu with existing subclass names is available for easy reference, as seen in Fig. 157.

Click in the Name field of the dialog box to enable the field for edit. Type in Chimp and click OK. Chimp now appears in the taxonomy tree as a subclass of Hominoid. The Text Editor also shows that Chimp :: Hominoid [||] is added to family.flr. These can be seen in Fig. 158.

One thing to note is that after adding a class to the KB, removing it may require some manual effort. This is because while the definition of a class can be removed cleanly, its usage may span multiple files. One way to completely remove a class is to make use of the KB Search capbility from within the KB Editor. To see how this is done, save family.flr to permanently keep the changes made. This can be done by using File > Save or by clicking the Save button in the main navigation menu, as shown in Fig. 159. Once the file is saved, the * in the family.flr tab should disappear.

Click and highlight class Hominoid in the taxonomy window, and select Find in KB Search from the right-click menu. This produces a list of all occurrences of Hominoid in the KB, as shown in Fig. 160.

Click and highlight an occurrence in the list. This loads the corresponding .flr file into the Text Editor as well as highlighting the occurrence in the file, as shown in Fig. 161. By clicking each search result in turn, all occurrences of Hominoid can be removed manually using the Text Editor.
