title: What are "synchronization points"?
body: <p>In Meld there is an option available to add synchronization points. Unfortunately I cannot figure out what these so called synchronization points do. I have messed around with it but it doesn't actually seem to do anything (except break live comparison).</p>
  
  <p>I have checked the manual and searched around but have not been able to solve this mystery.</p>
  
  <p>The option is available in the edit menu and in the context menu:</p>
