Notes


      Notes: A hotlist is a good way to provide easy access to a
        a number of frequently used items such as directories.
        The hotlist resides in a text file of the following format.
          Line 1: Title line
          Line 2: Title line
          Line 3: Value_1
          Line 5: Description_1.
          Line 6: Value_2
          Line 4: Description_2.
            . . .
        First two lines (title lines) are ignored.
        Values and descriptions are text strings.
        Descriptions are what are actually displayed in the
        hotlist. The corresponding value is returned.
     
        The hotlist modification buttons (along widget bottom)
        update the hotlist file.
