<h4><span style="color:#ffbb66;"><strong>vim三种模式</strong></span></h4> 
<ul><li><strong>命令行模式&#xff1a;在此模式下可以控制屏幕光标移动&#xff0c;字符或行的删除&#xff0c;移动复制某区段及进入插入模式或者底行模式</strong></li><li><strong>插入模式&#xff1a;只有在此模式下才可以做文字输入&#xff0c;按ESC即可退到命令行模式</strong></li><li><strong>底行模式&#xff1a;将文件保存或退出vim&#xff0c;也可以设置编辑环境&#xff0c;如寻找字符串、列出行号……等。</strong></li></ul> 
<p><strong>ps&#xff1a;一般我们在使用时把vim简化成两个模式&#xff0c;就是将底行模式也算入命令行模式</strong></p> 
<h4><span style="color:#ffbb66;"><strong>基本操作</strong></span></h4> 
<p><strong>vim filename 就会进入到文件内部&#xff0c;进去就是命令行模式</strong></p> 
<p><strong><span style="color:#3399ea;">切换至插入模式</span>&#xff1a;按下</strong><span style="color:#f33b45;"><strong>【a&#xff0c;A&#xff0c;i&#xff0c;I&#xff0c;o&#xff0c;O】</strong></span><strong>即可进入插入模式</strong></p> 
<p><strong>a&#xff1a;当前位置下一个开始输入</strong></p> 
<p><strong>A:当前行行尾开始输入</strong></p> 
<p><strong>i&#xff1a;当前位置前一个位置开始输入</strong></p> 
<p><strong>I&#xff1a;从当前行行首开始输入</strong></p> 
<p><strong>o&#xff1a;下一行开始输入&#xff08;另起一个新行开始输入&#xff09;</strong></p> 
<p><strong>O&#xff1a;上一行开始输入&#xff08;另起一个新的行开始输入&#xff09;</strong></p> 
<p><span style="color:#3399ea;"><strong>进入replace模式按下</strong></span><span style="color:#f33b45;"><strong>r或者R</strong></span></p> 
<p><strong>r&#xff1a;替换一个字符之后就退出了replace模式进入了命令行模式</strong></p> 
<p><strong>R&#xff1a;一直处于replace模式&#xff0c;除非手动退出该模式</strong></p> 
<p><strong><span style="color:#3399ea;">切换至命令行模式</span>&#xff1a;按下<span style="color:#f33b45;">ESC</span>即可</strong></p> 
<p><strong><span style="color:#3399ea;">切换至底行模式</span>&#xff1a;按下[  <span style="color:#f33b45;">:   /    ?</span>]任意一个即可进入底行模式</strong></p> 
<p><strong>底行模式退出vim及保存文件&#xff1a;按下【&#xff1a;】进入底行模式</strong></p> 
<p><strong>&#xff1a;w filename   将文章以指定的文件名filename保存&#xff08;与你当前操作不冲突&#xff0c;另存&#xff09;</strong></p> 
<p><strong>&#xff1a;wq  存盘并退出vim</strong></p> 
<p><strong>: q!   不存盘强制退出vim</strong></p> 
<h4><span style="color:#ffbb66;"><strong>移动光标</strong></span></h4> 
<p><strong>处于命令行模式下操作以下命令</strong></p> 
<p><strong><span style="color:#f33b45;">「h」、「j」、「k」、「l」</span>&#xff0c;分别控制光标左、下、上、右移一格。</strong></p> 
<p><strong>按「ctrl」&#43;「b」&#xff1a;屏幕往“后”移动一页&#xff08;看到上一页&#xff09;</strong></p> 
<p><strong>按「ctrl」&#43;「f」&#xff1a;屏幕往“前”移动一页&#xff08;看到下一页&#xff09;</strong></p> 
<p><strong>按「ctrl」&#43;「u」&#xff1a;屏幕往“后”移动半页。&#xff08;看到上半页&#xff09;</strong></p> 
<p><strong>按「ctrl」&#43;「d」&#xff1a;屏幕往“前”移动半页。&#xff08;看到下半页&#xff09;</strong></p> 
<p><strong>按「gg」&#xff1a;移动到文章的开头。</strong></p> 
<p><strong>按「G」&#xff1a;移动到文章的最后一行开头。&#xff08;【nG】移动到这个文件的第n行(可配合<span style="color:#f33b45;">:set nu</span>)&#xff09;</strong></p> 
<p><strong>按「$」&#xff1a;移动到光标所在行的“行尾”。</strong></p> 
<p><strong>按「^」&#xff1a;移动到光标所在行的“行首”</strong></p> 
<p><strong>按数字「0」&#xff1a;移动到光标所在行的“行首”</strong></p> 
<p><strong>按「w」&#xff1a;光标跳到下一行的开头&#xff08;最后一行先跳到头再跳到行尾&#xff0c;与b不同&#xff0c;w是往下找&#xff0c;b往上找&#xff09;</strong></p> 
<p><strong>按「e」&#xff1a;光标跳到每一行的的行尾&#xff08;当前光标若不是当前行的最后一个元素&#xff0c;会先跳到当前行最后一个再往下一行最后一个跳&#xff0c;直到最后一行&#xff09;</strong></p> 
<p><strong>按「b」&#xff1a;光标回到每一行的开头&#xff08;当前光标若不是当前行的第一个元素&#xff0c;会先跳到当前行第一个再往上一行第一个元素跳&#xff0c;直到第一行&#xff09;</strong></p> 
<p><strong>按「#l」&#xff1a;光标移到当前行光标位置后的第#个位置&#xff0c;如&#xff1a;5l&#xff08;移动到当前光标后5个元素&#xff0c;必须在本行&#xff09;</strong></p> 
<p><strong>【H】 光标移动到<span style="color:#f33b45;">这个屏幕</span>的最上方那一行的第一个字符&#xff08;与gg不同&#xff09;<br /> 【M】 光标移动到这个屏幕的中间那一行的第一个字符<br /> 【L】光标移动到这个屏幕的最下方那一行的第一个字符</strong></p> 
<p><strong>【n&lt;Enter&gt;】光标向下移动n行</strong></p> 
<h4><span style="color:#ffbb66;">删除文字</span></h4>
