This plugin shows emojis by using shortcodes. It will not override the default <a href="https://codex.wordpress.org/Using_Smilies" title="WordPress Smileys" rel="nofollow ugc">Smileys</a>.
How To Use:
<ol>
<li>After activating this plugin, an emoji icon will appear next to your “Add Media” button above the editor window.</li>
<li>Click on that button to display the dropdown list of available emojis.</li>
<li>Click “Add Shortcode”, and the shortcode will automatically be added to your editor window.</li>
</ol>
Alternatively, you can type in your shortcode by hand using this format:
<pre><code>[sce emoji="happy" /]
</code></pre>
