Using the Synchronize Environments extension (AEN 4.2.1)
========================================================

.. raw:: html

    <p>The Synchronize Environments extension allows you to apply a Python, R language
    or any other custom environment inside your current notebook session, without
    needing to start up several Notebook instances using each of the selected
    environments.</p>
    <p>To change environments:</p>
    <ol class="arabic">
    <li><p class="first">Open the <strong>Kernel</strong> menu.</p>
    <div class="figure">
    <img alt="../../../../../../_images/ae-notebooks/4.2.1/aen-user-extensions_kernels41.png" src="../../../../../../_images/ae-notebooks/4.2.1/aen-user-extensions_kernels41.png" />
    </div>
    <div class="line-block">
    <div class="line"><br /></div>
    </div>
    </li>
    <li><p class="first">Click the Change kernel option.</p>
    </li>
    <li><p class="first">From the list, select the environment to use.</p>
    </li>
    </ol>
    <p>NOTE: In AEN 4.1+ the default kernel for projects is <code class="docutils literal"><span class="pre">default</span></code>. In versions
    prior to 4.0, the default kernel for projects is <code class="docutils literal"><span class="pre">root</span> <span class="pre">Python</span></code>.</p>
