title: Quickest way to change a pair of parenthesis to brackets in vim
body: <p>I am new to vim and in the process of discovering tons of interesting things that one can using this powerful editor. </p>
  
  <p>One particular thing that I need to do very frequently is to change a pair of parenthesis in the text to square-brackets  (for example to change <code>( (a+b+c) )</code> to <code>[ (a+b+c) ]</code>) or vice-verso. I now do this by manually changing the two characters <code>(</code> and <code>)</code> to <code>[</code> and <code>]</code>. </p>
  
  <p>However, when there is a lot of text in between the parenthesis, it could be difficult to locate the pair of opening and closing parenthesis especially because after changing the first <code>(</code> to <code>[</code> then the <code>%</code> command will no longer be able to find the corresponding <code>)</code>.</p>
  
  <p>I was wondering if there is a better and quicker way to make such changes?</p>
