  It is a given that I will be using SSH and terminal mode in both
  the host and the clients.

  The current keymaps have been used for years in gui mode. The new
  prefixes are : C-j, C-u and C-]. And there *have* been problems
  which have been worked out ...

  Say what? :) Never heard of them. I will be googling them as soon
  as I finish this message. Feel free to elaborate if you have the
  time and inclination.

  Thanks for the tip on 'info.
  I am currently rewriting my binding code so that I can set a
  global variable that will enable the C-j, C-l etc binding 
  OR
  C-c j, C-c l etc.

  Let way I can compare effects on my hands.

  Indeed. You're absolutely correct, although I have already worked
  out many of those issues. The tradeoff is that with using
  control-C
  (see
  https://www.gnu.org/software/emacs/manual/html_node/elisp/Key-Binding-Conventions.html
  and the following statement
  "Don't define C-c letter as a key in Lisp programs. Sequences
  consisting of C-c and a letter (either upper or lower case) are
  reserved for users; they are the only sequences reserved for
  users")

  I would have to reach down more with my index finger but I
  wouldn't have to worry about collisions and I would have the
  potential of shorter sequences with more keymaps.

  We've wandered far from the original question, but I have learned
  much. 
  
  Robert, thanks for your concise explanations and for being so
  patient with my unorthodox approach.
