Question

是否可以在Emacs中滚动缓冲区的整个可见部分，但是将点保留在原点。示例：point指向窗口的底部，我想看到一些从窗口顶部滚动而没有移动点的文本。

编辑：我认为C-l C-l符合我的要求。

Answer 1

试试这些。根据您的口味更改M-n和M-p键绑定

;;; scrollers
(global-set-key "\M-n" "\C-u1\C-v")
(global-set-key "\M-p" "\C-u1\M-v")

Answer 2

这可能有用。根据滚动的EmacsWiki页面;

变量scroll-preserve-screen-position可能对某些人有用。当您向下滚动并向上滚动时，点应该以相同的方式结束你开始的位置。可以通过构建来切换值在模式M-x scroll-lock-mode。

Answer 3

;;;_*======================================================================
;;;_* define a function to scroll with the cursor in place, moving the
;;;_* page instead
;; Navigation Functions
(defun scroll-down-in-place (n)
  (interactive "p")
  (previous-line n)
  (unless (eq (window-start) (point-min))
    (scroll-down n)))

(defun scroll-up-in-place (n)
  (interactive "p")
  (next-line n)
  (unless (eq (window-end) (point-max))
    (scroll-up n)))

(global-set-key "\M-n" 'scroll-up-in-place)
(global-set-key "\M-p" 'scroll-down-in-place)

Answer 4

;; Preserve the cursor position relative to the screen when scrolling
(setq scroll-preserve-screen-position 'always)

;; Scroll buffer under the point
;; 'scroll-preserve-screen-position' must be set to a non-nil, non-t value for
;; these to work as intended.
(global-set-key (kbd "M-p") #'scroll-down-line)
(global-set-key (kbd "M-n") #'scroll-up-line)
