title: Using special characters as keywords in latex listings package
body: <p>I am using the listings package for latex.  I am using the SQL language definition and am adding some new keywords that I need, using morekeywords=.</p>
  
  <p>I have trouble defining some special characters as keywords, for example, I need 
  [], &lt;>, &amp;, and -> 
  to be considered as keywords and use the keyword style.</p>
  
  <p>I have tried adding these verbatim or with a preceding backslash.<br>
  It did not work.</p>
  
  <p>Your help would be greatly appreciated.</p>
  
  <p>Thanks.</p>
