The K2 theme provides a number of additional hooks into the template. If you’re handy with PHP you can easily add any manner of arbitrary content to these 8 regions. For everyone else, there is K2 Hook Up.
This plugin provides an options screen with each unique hook exposed as a simple text box. Insert any HTML, CSS, JavaScript, or PHP that you like, and click submit and it will be instantly published to that region of your template.

If you aren’t altogether comfortable with editing PHP files to customize your site, OpenHook is for you! An increasing number of themes & plugins come equipped with a myriad of hooks — points within their code which can receive user customizations, known as actions — which can be customized from within your WordPress admin panel using OpenHook!
OpenHook brings the world of hooks & actions to the mainstream, providing an easy to use admin interface in which you can customize your site without limit, whether you’re using HTML/CSS/JavaScript or PHP!
Features
<ul>
<li>Customize the hooks present in your favorite themes!</li>
<li>Define any hook you want within OpenHook and add an action to it! In addition to the themes which OpenHook supports explicitly, you can now use OpenHook to customize ANY hook (even something as arcane as <code>theme_hook_before_meta_987</code>) in ANY theme or plugin that has ANY hooks, from WordPress’ bare minimum hooks to hooks that are dynamically created and are as infinitely diverse as your site can be!</li>
<li>Predefined hooks for Astra, the world’s most popular non-default WordPress theme!</li>

<li>Shortcodes
<ul>
<li>[email], for masking email addresses from some spam robots</li>
<li>[global], which makes use of custom fields on a draft page in order to provide a library of reusable strings</li>
<li>[php], an admin-only shortcode for including PHP code within posts</li>
<li>[snap], an easy way to include (nearly) always up-to-date screenshots of websites within your posts</li>
</ul>
