emacs怎么实现VI里的ctrl+y和ctrl+e??

Rcjun

输入模式的ctrl+y  ctrl+e
觉得VI的这两个功能很实用:p

Vel

vi中C-e的功能叫scroll-up，在emacs中的函数就叫scroll-up，用C-h f scroll-up查看它的说明
C-y叫scroll-down

pupilzeng

scroll-down is an interactive built-in function in `C source code'.
It is bound to <prior>, M-v.
(scroll-down &optional ARG)

Scroll text of current window down ARG lines.
If ARG is omitted or nil, scroll down by a near full screen.
A near full screen is `next-screen-context-lines' less than a full screen.
Negative ARG means scroll upward.
If ARG is the atom `-', scroll upward by nearly full screen.
When calling from a program, supply as argument a number, nil, or `-'.
这是绑定到了哪个键？
<prior>是什么意思？

兄弟误会了

我说的不是命今模式中的C-y,C-e

而是在按了i,a,o等键后的那个编辑模式。

在那个模式中按住C-y可以把上一行的字一个个地复制下来，C-e则是复制下一行的。

Emacs中有没有类似这个的功能呢？

alt+v

还有vim中的这几个命令，很方便的，可不知道怎么在emacs中实现：
dd
Y

以我用emacs的经验，我相信emacs里面是没有现成的这样功能。不过要自己写一个是很简单的事情。

1. (defun vim-insert-mode-C-y-or-C-e (&optional C-e?)
   
2.   "Do that fking stuff for some emacs newbies, which is thought as somewhat 'usable'
   
3. in that fking vim ... Only losers will use this fk in emacs, I think."
   
4.   (interactive "P")
   
5.   (let* ((arg-line (if C-e? 2 0))
   
6.          (pos-of-char-to-insert
   
7.           (if (>= (- (point) (line-beginning-position))
   
8.                  (- (line-end-position arg-line) (line-beginning-position arg-line)))
   
9.               nil
   
10.             (+ (line-beginning-position arg-line) (- (point) (line-beginning-position))))))
    
11.     (if pos-of-char-to-insert
    
12.         (insert (char-after pos-of-char-to-insert))
    
13.       (beep)
    
14.       )))
    
15.          
    
16. (defun vim-insert-mode-C-e ()
    
17.   (interactive)
    
18.   (vim-insert-mode-C-y-or-C-e t))
    
19. 
    
20. ;; bind these shit, if you really want to.
    
21. (global-set-key [?\C-y] 'vim-insert-mode-C-y-or-C-e)
    
22. (global-set-key [?\C-e] 'vim-insert-mode-C-e)

本来想试试这个代码的
但是冲着这句话，我是绝对不会用你的这个代码的

"Do that fking stuff for some emacs newbies, which is thought as somewhat 'usable'
in that fking vim ... Only losers will use this fk in emacs, I think.

Then hack it by yourself, better this way.

Remember this, emacs is NOT a vim substitute. We have a much better life style with emacs.
