title: VIM snippet phrase dropdown menu
body: <p>Is there way in VIM to have a keystroke invoke a drop-down menu (similar to code completion) , but lists lines of text from a text file to choose from?</p>
  
  <p>I have a list of macros that I want to choose from. Examples are such...</p>
  
  <ul>
  <li>`ABX_ERR("message",value);</li>
  <li>`ADD_TASK(name task);
  so on...</li>
  </ul>
  
  <p>I would like to see all of these in a drop-down menu that I can choose from to insert into the file.</p>
