I swear I’ve manually entered a list of pages under a “parent” page to show the “child” pages inside of a page or a post. Duh. “Hmm, let’s do a quick search for “List Pages Shortcode” in the WordPress plugin directory. Or worse, try to get the PHP code from the WordPress Codex to list pages in there, oh wait, need a plugin to allow the PHP script to run within a post and then need to find the right PHP code. Yeah, that’s fun.
