title: RefTeX with biblatex field names
body: <p>I'm using RefTeX in EMACS. I have a bibliography file which uses biblatex's field names e.g. I have 'Journaltitle' instead of bibtex's 'Journal'. Here's an example entry:</p>
  
  <pre><code>@article{BerwickPietroskiYankamaChomsky2011,
      Author = {Berwick, Robert C. and Pietroski, Paul M. and Yankama, Beracah and Chomsky, Noam},
      Doi = {10.1111/j.1551-6709.2011.01189.x},
      Journaltitle = {Cognitive Science},
      Pages = {1207--1242},
      Title = {Poverty of the Stimulus Revisited},
      Volume = {35},
      Year = {2011}}
  </code></pre>
  
  <p>When I use <code>C-c [</code> everything works, but I don't see the 'Journaltitle' field displayed i.e. I don't see 'Cognitive Science'. This is because RefTeX is looking for 'Journal'; adding a 'Journal' field to the record results in it showing up.</p>
  
  <p>Two questions:</p>
  
  <ol>
  <li>Is that what's going on?</li>
  <li>Can I tell RefTeX to look for biblatex fields? (The manual didn't help me.) </li>
  </ol>
