        <h1>Template Plugin: Selected Content Replacement</h1>
        <p>This is an example of replacing selected content within the TinyMCE editor with content from the <a href="" target="_blank">template</a> plugin in TinyMCE 5.</p>
            <p>Content authors can write their content in the editor, and they may need to insert a button with a specific label.</p>
            <p>All they need to do is write the label, select the label text, and insert the template. Their selected content will be inserted in to element with the class "template_selected_content_classes" within the template they select.</p>
            <p>New Button Label</p>
            <p>Select the line above, and click the "Insert Template" button in the template. There is only one template, so that will be pre-selected - just click Save. You will see the line above be replaced with the template, and the selected content be inserted in to the template.</p>
        <p>For this example, the template source is within the TinyMCE init configuration. This will make it easier to
            play with the example. In a real-world use case, you may like to use <a href="" class="_blank">externally hosted templates</a>.</p>
        <p>Refer to the <a href="" target="_blank">template_selected_content_classes</a> documentation for further details.</p>
