title: In Jupyter notebook, how to change auto indent to tab instead of 4 spaces
body: <p>I just started using jupyter notebook. Google search didn't help. Thanks!</p>
  
  <p><strong>Update: Quick Summary of answers</strong></p>
  
  <p>Running the following code in a cell before you start a ipython file got the task done for me. One problem is that we have to run this everytime for each file.</p>
  
  <pre>
  
      %%javascript
  
      // apply setting to all current CodeMirror instances
      IPython.notebook.get_cells().map(
          function(c) {  return c.code_mirror.options.indentWithTabs=true;  }
      );
  
      // make sure new CodeMirror instances created in the future also use this setting
      CodeMirror.defaults.indentWithTabs=true;
  
  </pre>
