title: How to highlight or mark a line in vim
body: <p>We can highlight different marks in vim using mark.vim but, how can I highlight a line in Vim?</p>
  
  <p>For example:</p>
  
  <pre><code>Line One
  Line Two
  Line Three
  </code></pre>
  
  <p>I let the cursor on line one, I highlight <code>line one</code>, the whole line is highlighted.
  Then I type <code>jj</code> to move to line 3, the line one is highlighted too, but didn't disappear.</p>
