Question

要复制和粘贴一行我使用以下方法

C-a - beginning of line

#save the line to kill-ring using kill-line(this is faster than marking,
# move to end of line and C-w)
C-k - kill-line
C-/ - undo kill-line 

# move point to required line
C-p or C-n or C-s (search for the nearest line where the paste must be done)

C-y # paste the line

是否有比这更有效的方法。在vim中输入 yy ，导航并 p 完成工作

Answer 1

使用kill-whole-line代替 C-a C-k 。它默认映射到 C-S-backspace 。

Answer 2

使用evil-mode，只需使用默认的vim键绑定。http://wikemacs.org/index.php/Evil

否则，M-w（kill-ring-save）会保存该区域。如果我们想要在没有选择区域的情况下复制当前行：

(put 'kill-ring-save 'interactive-form
 '(interactive
   (if (use-region-p)
       (list (region-beginning) (region-end))
     (list (line-beginning-position) (line-beginning-position 2)))))
(put 'kill-region 'interactive-form
 '(interactive
   (if (use-region-p)
       (list (region-beginning) (region-end))
     (list (line-beginning-position) (line-beginning-position 2)))))
