ps: the "Tables" your seeking are SIMPLE ENOUGH to keep in your head (like the
alphabet front-to back, back to front in pre-ordained "positionings") and can
be DONE at a whim if/WHEN required. (AND the TIME IS NOW !!!!) (es)
I may *pop* in and out here, as my ISP was resold (again, sigh :-( to
access1.com? in hawaii (hilo.com)? majordomo help (ha.haa)!!! I'm around the
world already and never left the barn here :-)
IF this even makes it to the VMS list... please reconsider:
1:Folding your KEY (my Diac.com page now down temp: did any one grab it?)
2:FLIPing your KEY on C_gallows_C (or visa verse gallows)
3:Insert (suspected /not english) LANGUAGE of choice in TTT quadrants.
4:Go with the ~FLOW~ of the gallows (per page START gallows/ & paragraphs)
5:8 KEYS TOTAL (THAT is is & good SIMPLER than you THOUGHT - eh?)
The Lower case vms characters (non-gallows)are _positioning "pointers"_ to the
TTT key you are on. EACH "individual character" can be a pointer to any (static
area) of the 8 KEYS so never lose your PATH or Positioning. ALWAYS START AT TOP
OF PAGE! (beginning section/folio etc..)
best to you & yours
