Re: some directory changing tools to share


Thank you very much for your interest and comments.  I am
aware that completion does some of what "c" does, but
perhaps not "most".  

The real potential of "c" is not in simply moving down the
subdirectory tree from the current directory, but to jump to
another directory and then move down from there, namely, the
use of aliases, such as "P t g" to go to ~/Perl/Test/Gui or
in combination with the "d" operator.
