Insert Pages lets you embed any WordPress content (e.g., pages, posts, custom post types) into other WordPress content using the Shortcode API. It also includes a widget for inserting pages into any widget area.
The real power of Insert Pages comes when you start creating custom post types, either programmatically in your theme, or using another plugin like Custom Post Type UI. You can then abstract away common data types (like videos, quizzes, due dates) into their own custom post types, and then show those pieces of content within your normal pages and posts by Inserting them as a shortcode.
EXAMPLE: [insert page=’page-name|ID’ display=’content’]
