title: How can I add keywords to common editors？
body: <p>I'm learning data structure. I tried coding to assist my learning. Sometimes I need to highlight some keywords in pseudo code (&quot;SeqList&quot;,&quot;SqList&quot;,&quot;ElemType&quot;) as the color of the preset keywords (&quot;int&quot;).</p>
  <p>I do know I can add keywords in vim, for example, <code>: syn keyword type seqlist</code>, could dye the word &quot;seqlist&quot; as &quot;int&quot;. But I wonder if mainstream editors (vscode, clion, Xcode, sublime) can achieve this?</p>
