How does WP generate html?

Question

I think this must be a simple question, despite the seemingly broad title. My wordpress theme by default displays several social icons. (You can see them here, in the upper right corner.) I'm trying to add a new icon to the existing ones. I've already generated and uploaded a new image, modified all the css and php files that (I think) required modification. However, I'm missing one key thing: somewhere, somehow the theme generates some source html that includes an unordered list that displays the icons:

<ul id="socialize-icons">
    <li id="icon-rss"><a href="http://somelink.com">RSS Feed</a></li>
    <li id="icon-facebook"><a href="http://somelink">facebook</a></li>
    <li id="icon-twitter"><a href="http://somelink">twitter</a></li>
</ul>

I cannot figure out where this code is generated so that I tweek it to include my new additional icon. If someone could point me in the right direction (a function, some wp documentation), I'd really appreciated it.

Answer 1

As @Ambitious Amoeba indicated above, what I was looking for was hardcoded in the footer template.

Answer 2

HTML markup can be generated in several ways:

• directly included in theme's template files;
• generated by template tags in templates;
• generated by native or plugin functions attached to hooks.

From quick look at this specific theme's code I found this:

array(  "name" => "Socialize Icons",
            "desc" => "Enter Links to Your Twitter, Facebook, and RSS feeds.<br />If you want to remove the icon, clear the field and save this page",
            "type" => "socialize_icons"),

Which makes me think it has theme options page, where you can change or make blank those fields.
