title: When should i use <leader> mapping in vim?
body: <p>I'm a vim's newbie. I'm trying to do some remapping in vim.</p>
  
  <p>When i use:</p>
  
  <pre><code>map &lt;leader&gt;cp &lt;Esc&gt;:CtrlP&lt;return&gt;
  
  nmap cp :CtrlP&lt;return&gt;
  </code></pre>
  
  <p>It does the same thing.</p>
  
  <p>I know what <code>&lt;leader&gt;</code> is. But i want to know the different between normal mapping and mapping with <code>&lt;leader&gt;</code> mapping.</p>
  
  <p>So what is the different between them? When should i use <code>&lt;leader&gt;</code> for mapping?</p>
