Thanks for the suggestions.  'C-x SPC' activates 'rectangle-mark-mode'
that already supports short key sequences similar to 'repeat-mode':

  (defvar rectangle-mark-mode-map
    (let ((map (make-sparse-keymap)))
      (define-key map [?\C-o] 'open-rectangle)
      (define-key map [?\C-t] 'string-rectangle)
      (define-key map [remap exchange-point-and-mark]
        'rectangle-exchange-point-and-mark)
      (dolist (cmd '(right-char left-char forward-char backward-char
                     next-line previous-line))
        (define-key map (vector 'remap cmd)
          (intern (format "rectangle-%s" cmd))))

There are already single keys to edit the rectangle.
If you want, you can request more short keys to be
added to rectangle-mark-mode-map in a separate report.
So it seems this request can be closed now.
