<li>任何时候 <tt class="docutils literal">tab</tt> 键，会根据当前的输入给出提示</li>
<li>命令后敲 <tt class="docutils literal">-</tt> 或 <tt class="docutils literal">--</tt> ，然后按 <tt class="docutils literal">tab</tt> 键，可以展示出此命令具体的选项</li>

<div class="section" id="">
<span id="id1"></span><h2>自定义快捷键<a class="headerlink" href="#" title="永久链接至标题">¶</a></h2>
<p>在当前用户目录下新建<tt class="docutils literal">$USER_HOME/.arthas/conf/inputrc</tt>文件，加入自定义配置。</p>
<p>假设我是vim的重度用户，我要把<tt class="docutils literal">ctrl+h</tt>设置为光标向前一个字符，则设置如下，首先拷贝默认配置</p>
<div class="highlight-default notranslate"><pre class="literal-block">"\C-a": beginning-of-line
"\C-e": end-of-line
"\C-f": forward-word
"\C-b": backward-word
"\e[D": backward-char
"\e[C": forward-char

"\e[A": previous-history
"\C-h": backward-delete-char
"\C-?": backward-delete-char
"\C-u": undo
"\C-d": delete-char
"\C-k": kill-line

</div>
<p>然后把<tt class="docutils literal">"\C-h": backward-delete-char</tt>换成<tt class="docutils literal">"\C-h": backward-char</tt>，然后重新连接即可。</p>
