  <title> IPython Console Plugin</title>
  <p>
    The IPython Console Plugin allows real-time interaction with a selected item in the <link xref="desktop_tree_view">
    Application Tree View</link>. Since the IPython Console Plugin is an interactive Python shell, you can import any Python
    modules you want.
  </p>

  <note style="tip">
    <p>
      Make sure you have the standalone package IPython installed in your system. Otherwise, the IPython Console Plugin will
      not work properly.

    <title>Running the IPython Console Plugin</title>
    <p>
      To run the IPython Console Plugin, select one of the accessible items
      listed in the Application Tree View - either an application or a widget. In the plugin, the
      selected item will correspond to the variable 'acc'. 
    </p>
    <p>     
      Pressing <key>Tab</key> shows completions for the current command in the console,
      what can be useful for discovering pyatspi methods.
    </p>
