To change the information in the tabs of the pages, we can use the pageconfigure method. For example, the following command:
.nb pageconfigure hd -label "Fixed Disk"
changes the label from ``Hard Disk'' to ``Fixed Disk''. To delete a page, we can use the delete method.
You should avoid using the pageconfigure and delete. Your users will just feel annoyed if the interface changes all the time and notebook pages appear and disappear every now and then.
