 * This file is a wrapper around a modified version of the "BibTex" translator from Zotero 2.1.10, 
 * which uses available methods from that translator for extracting / generating a BibTeX-compatible cite key.
 * This Translator uses a greatly simplified doExport() function to output only "\cite{key}" on export.
 * By setting "Quick Copy" to use this translator (in Zotero 'Export' Preferences), you can 
 * Drag & Drop citations in the form of a Bibtex "\cite{key}" from Zotero.
 * There are a few variables near the top that allow simple control over the formatting of this exported content,
 * Such as which command to use (if any), and what to put between multiple items.
 *
 * Original tweaks by:  Andrew Leifer               leifer ( at ) fas ( dot ) harvard (dot) edu
 * Inspired by similar work by: Avram Lyon          ajlyon [at] gmail.com     
 */
/* TODO
 * Can Zotero search dynamically for the preferred "bib" translator (according to priority)?
 * - e.g. something like .getTranslators() method
 *   http://www.zotero.org/support/dev/translators/coding#calling_other_translators
 */

var citeCommand = "\\cite"; //jaw -- specify preferred cite command (escape the backslash).
var keySep      = ", ";      //jaw -- used to separate multiple keys within the command above.
/*jaw  
 * Multiple keys will be separated by `keySep`: default is a comma + space ", "
 * The cite key(s) will be wrapped in curly braces {}, with `citeCommand` appended to the front.
 * Leave `citeCommand` blank ("") if you just want the naked cite key(s) on Quick Copy.
