整理收集一些vi常用命令，备忘。

如果觉得操作不方便，你可以在.vimrc里自定义快捷键，比如：

nmap  <C-B> :bnext<CR>

这样CTRL + B就相当于:bnext加回车。

这些命令可以修改文本，但是仍使你处于命令模式下。

• x 删除当前光标下字符
• J 将下一行加到当前行末尾
• r(char) 用char替换当前光标下字符
• dd 删除当前行
• d(OFFSET) 从当前位置向后删除OFFSET个字符
• u 撤销
• o 重复上一条编辑命令

任意这些命令会将你置于插入模式下， 你可以输入文本，敲击回车来开始新行，用上下左右来移动，用Del删除。 按ESC可以回到命令模式。

• i/a 插入到当前位置前/后
• I/A 插入到当前行的开始/末尾
• o/O 另起下/上一行开始输入
• cc 替换当前行
• c(OFFSET) 替换到当前位置后的OFFSET位置

vi开始体现出真正威力，所谓所想即所得

• 3⇒ 光标向右移动3个字符
• 4) 光标向后移动4句
• 2b 光标向左移2个单词

• d3w 删除后面三个单词
• d} 删除本段光标后面部分
• d) 删除本句光标后面部分

• c) 替换本句其余部分
• c$ 替换本行后面部分

利用可视化模式

1. 按v进入可视化模式
2. 移动光标高亮需要重用的文本
3. 按d剪切，按y复制
4. 移动光标到目标位置
5. 按P粘贴到光标之后
6. 按p粘贴到光标之前

• :s/reg/rep/ 用rep替换当前行内首个匹配reg的字符串
• :s/reg/rep/g 用rep替换当前行内所有的匹配reg的字符串
• :%s/reg/rep/g 全文本替换
• :%s/reg/rep/gc 全文本替换前提是确认

• «= 向左缩进
• >⇒ 向右缩进

当然一般都用autoindent和各类源代码的缩进plugin来缩进
