title: What are the use cases of Vim's bracket ([ and ]) marks?
body: <p>According to <code>:h mark</code>:</p>
  
  <pre><code>                                                m[ m]
  m[  or  m]              Set the '[ or '] mark.  Useful when an operator is
                          to be simulated by multiple commands.  (does not move
                          the cursor, this is not a motion command).
  </code></pre>
  
  <p><code>m&lt;</code> and <code>m&gt;</code> can be pretty useful but the above description is too vague for me and I couldn't find any examples.</p>
