title: MS Word: change existing captions name
body: <p>this is my first post, so I would like to say hello :)</p>
  
  <p>I have a very large document, it consists of ~150 captions.
  I would like to change name of the captions, for example from 'Picture' to 'Pic.'
  Is there any simple method to do it? I can't imagine changing all of the existing captions and cross-references manualy.</p>
  
  <p>Best regards,
  Michal</p>
