title: How do I highlight code in pycharm?
body: <p>When I'm writing python script using pycharm, I quite often want to highlight a piece of code that I'm working on. e.g., at teh end of the day so I can find it quickly the next day, or if i want to examine another piece of code then return quickly to the section I was working on. </p>
  
  <p>If I was writing a Word document, for example, I might temporarily highlight the text so I can find it quickly. </p>
  
  <p>Is it possible in pycharm to use a temporary highlight or mark up in the code?</p>
