WordPress.org

Allows you to create small HTML templates to use inside your posts on pages. The templates can contain dynamic fields, wich you set the value when writing a post or page. The plugin adds a button to you TinyMCE Editor for you to choose the template you want to add.

Its perfect if you have a post or page layout you, or yours site user, post frequently. You can, for instance, create a template for all download links in your site and, when you press the button to add this template to your post, the plugin asks you whats the name and link of the file. Its very useful for creating tables as well.
