linux - 在emacs中取消设置键向上和向下翻页

Question

我可以使用以下功能取消设置左右键。

(global-unset-key [left])
(global-unset-key [up])
(global-unset-key [right])
(global-unset-key [down])

但是为什么我不能使用 global-unset-key 取消向上和向下翻页？下面的代码不起作用。

(global-unset-key [pgup])
(global-unset-key [pgdn])

您可以使用C-h k *key-you-want-to-look*.

;;; from *help* buffer, after C-h k pagedown
;; <next> runs the command scroll-up, which is an interactive built-in
;; function in `C source code'.

;;; from *help* buffer, after C-h k pageup
;; <prior> runs the command scroll-down, which is an interactive built-in
;; function in `C source code'.


(define-key (current-global-map) (kbd "<next>") nil) ; use whatever
(global-unset-key (kbd "<prior>"))                   ; you like
