WP-SNAP! (WordPress System for Navigating Alphabetized Posts) creates an alphabetical listing of post titles on a Category or Page template file. Navigation through the listings WP-SNAP! generates is accomplished using the alphabet itself. (For example, if a site visitor clicked on the letter D, any post titles that began with that letter would be showcased.) WP-SNAP! will work on any WordPress 2.5 or higher site, but is particularly useful managing glossaries, indexes, reviews, or directories.
WP-SNAP! offers three different navigational styles and integration with both custom permalinks and the WordPress loop. Plugin options can be managed both site-wide and on the template itself with results either restricted to one category or broadened to include child categories as well. The clever web developer should have no problem seamlessly integrating WP-SNAP! into their latest project. Options have also been added to allow the customization of css class names and the appearance of html mark-up.

This widget will get a list of post/cpt title first character. The list is then displayed as an unordered list of links. The links take the user to an archive page for the specific post type and display the posts where its title begins with the character.
If the title begins with the following words, the first character of the second word will be used:
<ul>
<li>A</li>
<li>An</li>
<li>And</li>
<li>The</li>
</ul>
Examples
<ul>
<li>‘A Cup of Joe’ will be listed under ‘C’</li>
<li>‘The Pony’ will be listed under ‘P’</li>
<li>‘Android Green is Nice’ will be listed under ‘A’</li>
<li>‘The 10 Strangest Foods’ will be places under ‘#’ (number sign)</li>
</ul>
