不敢独享，与大家分享。也可以在Emacs中用C-x C-h列出全部命令，查找C-x r c，所有列模式命令都是以C-x r开始的
C-x r C-@                    point-to-register
C-x r SPC                    point-to-register
C-x r +        increment-register
C-x r b        bookmark-jump
C-x r c        clear-rectangle
先用C-space或者C-@设一个mark，移动光标到另一点，使用C-x r c可以清楚mark到光标处的矩形区域，该区域留下空白。
C-x r d        delete-rectangle
删除矩形区域，不留空白，后面的字符前移
C-x r f        frame-configuration-to-register
C-x r g        insert-register
C-x r i        insert-register
将某个寄存器的内容插入某处
C-x r j        jump-to-register
C-x r k        kill-rectangle
就是剪切某个选定的矩形区域，用C-x r y可以贴上
C-x r l        bookmark-bmenu-list
C-x r m        bookmark-set
C-x r n        number-to-register
C-x r o        open-rectangle
在选定的矩形区域插入空白
C-x r r        copy-rectangle-to-register
将选定的矩形区域复制到某个寄存器
C-x r s        copy-to-register
C-x r t        string-rectangle
在选定区域所有列前插入同样的字符
C-x r w        window-configuration-to-register
C-x r x        copy-to-register
C-x r y        yank-rectangle
类似于矩形区域的粘贴，就是将刚用C-x r k剪切的矩形区域粘贴过来
C-x r C-SPC    point-to-register
