How to use the Theme Page reactions in context
You need to use a theme preprocess hook to pass the variable to the right zone template. Here's how I added it to my header zone:

function my_theme_preprocess_zone(&amp;$vars) {
    $zone = $vars['zone'];

    if ('header' == $zone) {
        $theme = alpha_get_theme();

        // set via context module
        if (isset($theme-&gt;page['section_title'])) {
            $vars['section_title'] = $theme-&gt;page['section_title'];
        }
    }
}


Then in your zone--header.tpl.php file

&lt;?php if (isset($section_title)): ?&gt;
&lt;div class="grid-&lt;?php print $columns ?&gt;"&gt;
    &lt;h1 class="section-title"&gt;&lt;?= $section_title ?&gt;&lt;/h1&gt;
&lt;/div&gt;
&lt;?php endif; ?&gt;
