本地覆盖emacs主模式的键绑定

Question

覆盖主模式的键绑定的正确方法是什么，因此它只会影响缓冲区本地键映射？我想我可以使用searchDetailCriteria或local-set-key，但我的尝试会影响全局的键盘映射（如下所示）。

是否有必要复制地图，如下所示，或创建具有不同键映射的次要模式？如果可能的话，能够使它成为局部变量会很好。

例如，假设我希望make-local-variable original绑定到全局C-c C-c，但在调用emacs-lisp-mode-map后我希望jump-to-other-buffer绑定到C-c C-c local-version仅限于该缓冲区。

(defun original ()
  (interactive)
  (message "original"))

(defun local-version ()
  (interactive)
  (message "local binding"))

;; open new buffer in emacs-lisp mode and set a local key
(defun jump-to-other-buffer ()
  (interactive)
  (with-current-buffer (get-buffer-create "*test1*")
    (emacs-lisp-mode)
    ;; These change bindings in all elisp buffers
    ;; (make-local-variable 'emacs-lisp-mode-map)
    ;; (define-key emacs-lisp-mode-map (kbd "C-c C-c") 'local-version)
    ;; (local-set-key (kbd "C-c C-c") 'local-version)
    (let ((overriding-local-map (copy-keymap emacs-lisp-mode-map)))
      (define-key overriding-local-map (kbd "C-c C-c") 'local-version)
      (use-local-map overriding-local-map))
    (pop-to-buffer (current-buffer))))

;; default binding in elisp buffers
(define-key emacs-lisp-mode-map (kbd "C-c C-c") 'original)
