title: A confusion about shortcut key of youcompleteme for vim
body: <p>all. I am trying to use youcompleteme for code completing in vim. Generally, it works well except that when i need to jump between source files. 
  First. I use the subcommand </p>
  
  <pre><code>:YcmCompleter GoToDefinition
  </code></pre>
  
  <p>it can find the definition. BUT it seems so verbose. Then I want to map this subcommand into some shortcut key according to the YCM's instruction:</p>
  
  <pre><code>nnoremap &lt;leader&gt;gl :YcmCompleter GoToDeclaration&lt;CR&gt;
  nnoremap &lt;leader&gt;gf :YcmCompleter GoToDefinition&lt;CR&gt;
  nnoremap &lt;leader&gt;gg :YcmCompleter GoToDefinitionElseDeclaration&lt;CR&gt;
  </code></pre>
  
  <p>I am a little confused. what is short cut key? l or gl ?</p>
