title: How to abbreviate path in Emacs?
body: <p>I want to abbreviate path in emacs.</p>
  
  <p>The standard behavior of emacs is : C-x C-f then typeset the complete name of a file. E.g.</p>
  
  <pre><code>C-x C-f ~/latex/project/style/test.sty
  </code></pre>
  
  <p>One can use  for quick completion of the path.</p>
  
  <p>As I frequently use two of three directories, I'm wondering if it's possible to gave some « abbreviated path ». E.g.</p>
  
  <pre><code>C-x C-f lstyle/test.sty
  </code></pre>
  
  <p>expanded automatically in « <code>~/latex/project/style/test.sty</code> »</p>
  
  <p>Thank you for any help !</p>
