title: Is it possible to highlight a keyword group in 'suffix mode' in Notepad++ User Defined Language?
body: <p>The User Defined Language model in Notepad++ (at least for version 7.X and above) allows for defining a Keyword group in 'Prefix mode'.</p>
  
  <p>A good description is taken from <a href="http://www.thevalvepage.com/swmonkey/2015/08/19/notepad-user-defined-languages/" rel="nofollow noreferrer">this blog post</a>:</p>
  
  <blockquote>
    <p>The more inquisitive of you may well be wondering what that <strong>[Prefix mode]</strong> checkbox is. Well it means the keyword just needs to be the starting characters e.g. if you untick this box and set a keyword of “<em>dont</em>” then only the exact word “<em>dont</em>” (give or take case sensitivity) will be treated as keywords. However if you tick this box then that one keyword will also match <strong><em>dont</strong>givemegrief</em>, <strong><em>dont</strong>makemylifemisery</em>, <strong><em>dont</strong>forcewindows10onme</em>, etc.</p>

  <p>I couldn't find any mention of this in documentation or elsewhere, though: is it possible to define a keyword group in <strong>"Suffix mode"</strong>? </p>
  
  <p>As an example the '<em>key</em>' keyword in Suffix mode should <em>not</em> match: </p>
  
  <blockquote>
    <p>keyword, key_test, key_1</p>
  </blockquote>
  
  <p>But <em>should</em> match:</p>
  
  <blockquote>
    <p><strong><em>key</em></strong>, <em>test_<strong>key</em></strong>,</p>
  </blockquote>
