复制和粘贴一行的有效方法

Question

若要复制和粘贴一行，请使用以下方法

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

有没有比这更有效的方法。在vim中，只需输入yy，导航，p就可以完成这项工作。

对于邪恶模式，只需使用默认的vim键绑定.http://wikemacs.org/index.php/Evil。

否则，M-w (杀环保存)将保存该区域。如果没有选定区域，则要复制当前行：

(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)))))
