These function examples are meant for people who have a minimal grasp of adding code to their functions.php, preferably in the child theme.

Comic Easel has an action location inside the navigation widget for the center section of it. In this section you can add additional buttons or text clicks like a buy now button or even a share click link.

add_action('inside-comic-navigation', 'custom_insert_into_navigation');

function custom_insert_into_navigation() { ?>
<script type="text/javascript" language="javascript">
function toggle() {
    var ele = document.getElementById("Share");
    var text = document.getElementById("displayShare");
    if(ele.style.display == "block") {
        ele.style.display = "none";
        text.innerHTML = "show";
    } else {
        ele.style.display = "block";
        text.innerHTML = "hide";
    }
} 
</script>
<div><a id="displayShare" href="javascript:toggle();">Share</a></div>
<?php }

This is an example of adding a function to execute into the inside-comic-navigation action location. What it does is output the script and a href to toggle the javascript necessary to open the CSS Share Element.

You could even do something really simple:

add_action('inside-comic-navigation', 'custom_insert_into_navigation_forum_link');

function custom_insert_into_navigation_forum_link() { ?>
      <a class="navi navi-forum" title="Frumph.NET Forums" href="http://forum.frumph.net/">Forum</a>
<?php }

In this example, all you are injecting is an href – link to go to the forums, it’s adding the appropriate classes so you can CSS them like the rest of the buttons/links in the navigation widget, and a unique class “navi_forum” specifically for that link.
