Load Textbook
The Load Textbook command reads a Textbook index file with the file name extension (.TXB) and uses the information in this file to create a Textbook menu at the far right of the menu bar. The Textbook menu provides convenient access to set of problems, such as those developed for use with a text. The default texbook menu is the Examples folder, which will be replaced if an allternative is provided. See Textbook index file for more information.
