WordPress has a little tab in the top-right corner that, when clicked, drops down some contextual help. Here is a super useful function to hook different help text to different pages.

Simply paste the code below into your functions.php file.

 //hook loading of new page and edit page screens add_action('load-page-new.php','add_custom_help_page'); add_action('load-page.php','add_custom_help_page');  function add_custom_help_page() {    //the contextual help filter    add_filter('contextual_help','custom_page_help'); }  function custom_page_help($help) {    //keep the existing help copy    echo $help;    //add some new copy    echo "<h5>Custom Features</h5>";    echo "<p>Content placed above the more divider will appear in column 1. Content placed below the divider will appear in column 2.</p>"; } 

Thanks to WP Tuts for the tip!
