1. Enter the mode BEFORE selecting the rectangle.

2. C-g exits the mode at any time.

3. M-x cua-rectangle-mark-mode

4. Use arrow keys to expand or contract the rectangle dimensions. Or
   use C-f, C-b, C-n, C-p, for cua-resize-rectangle-right,
   cua-resize-rectangle-left, cua-resize-rectangle-up,
   cua-resize-rectangle-down.

   + cua-resize-rectangle-eol - consider mapping this to C-e [DONE]
   + cua-resize-rectangle-bol - consider mapping this to C-a [DONE]

   + cua-resize-rectangle-bot - already mapped to M->
   + cua-resize-rectangle-top - already mapped to M-<
     + These two functions behaved unexpectedly. They extend the
       rectangle only vertically, not horizontally, so maybe they
       should be renamed or have their docstring edied to indicate
       something like "first/last line".

   + no issues with these; just noting their presence:
     + cua-resize-rectangle-page-up    M-v
     + cua-resize-rectangle-page-down  C-v

5. Mouse support - not evaluated.

6. Other navigation keys seem to be ignored for the purpose of
   selecting the cua-rectangle, even though they will move POINT. For
   example: C-a, C-e was shown to move point, but upon the next
   cua-rectangle naviigatiaa?on keystroke, POINT returned to its prior
   corner position.

7. Use the ENTER key, as needed, to toggle POINT amongst the
   rectangle's current corners in numeric POINT order (ie. for LTR
   languages, upper-left, upper-right, lower-left, lower-right).

8. Continue using the arrow keys, as needed, to expand or contract the
   rectangle dimensions.

9. One can recall the most recently selected rectangle, but only by
   returning POINT to its last selected corner, and then re-entering
   the mode.

10. cua-help-for-rectangle is currently bound to C-?, which is a pain
    for emacs-nox users. Remapped to M-?.

11. This mode does not seem to work for rtl (tested UTF-8 Hebrew)
