title: Sublime text, write multiple lines with increasing numbers
body: <p>In Sublime text, by selecting multiple lines, or <kbd>Ctrl</kbd>+clicking multiple lines, I can edit all of them at the same time. What I would like, is that the numbers in those rows would be different; increase with each line.</p>
  
  <p>Currently, for example, I would select 6 lines, press <kbd>Ctrl</kbd>+<kbd>Shift</kbd>+<kbd>L</kbd> to get multiple cursors on each of them, then write for example <code>article &gt; h1 { font-weight:normal; }</code>, and what comes out is: </p>
  
  <pre><code>article &gt; h1 { font-weight:normal; }
  article &gt; h1 { font-weight:normal; }
  article &gt; h1 { font-weight:normal; }
  article &gt; h1 { font-weight:normal; }
  article &gt; h1 { font-weight:normal; }
  article &gt; h1 { font-weight:normal; }    
  </code></pre>
  
  <p>And from here, if I want this to apply to all elements from <code>h1</code> through <code>h6</code>, I will edit each line manually to change the number. </p>
  
  <p>So my question is, can Sublime Text output an increasing number in each line in this scenario? Or is there another, easier way of changing them manually after they had all been set to 1's? </p>
