+<p>Within an editor window containing Python code, code context can be toggled
+in order to show or hide a pane at the top of the window.  When shown, this
+pane freezes the opening lines for block code, such as those beginning with
+<code class="docutils literal notranslate"><span class="pre">class</span></code>, <code class="docutils literal notranslate"><span class="pre">def</span></code>, or <code class="docutils literal notranslate"><span class="pre">if</span></code> keywords, that would have otherwise scrolled
+out of view.  The size of the pane will be expanded and contracted as needed
+to show the all current levels of context, up to the maximum number of
+lines defined in the Configure IDLE dialog (which defaults to 15).  If there
+are no current context lines and the feature is toggled on, a single blank
+line will display.  Clicking on a line in the context pane will move that
+line to the top of the editor.</p>
