Body: <p>I have an MKV file with multiple subtitles.  I would like to mark one set of those subtitles as default, so that it is turned on by default when the video starts playing.  NOTE: I do not want to "burn" this subtitles set into the video (I want to be able to turn these subtitles off at any point in time if I so choose).</p>
  
  <p>Is there an MKV editing tool that would allow me to do this?</p>

  There are two aspects to your query - 1)setting one of the subtitle streams as the default and 2)automatically displaying it during playback.I'm not aware of a method to force a player to display subtitles if that facility has been turned off in its settings.
  
  For the first facility, try mkvpropedit from [MKVToolNix](https://mkvtoolnix.download/index.html) to set the default flag for a subtitle stream. See 2nd [example](https://mkvtoolnix.download/doc/mkvpropedit.html#mkvpropedit.examples).
