Change directory b

     In order to change a subdirectory in Panel B you should perform one
of the following procedures:

1) Using the keys [Ctrl-Home], [Ctrl-End] move the selection bar onto the
   desired subdirectory and press [Ctrl--](dash) or
2) Move the mouse cursor onto the desired subdirectory and press the mouse
   left button twice.

     The parent directory is located at the beginning of the file list and
is marked by two periods. The procedure for changing the parent directory
is similar to that of the subdirectory.
