Enables the display of custom-field variables in the WordPress post editor via a TinyMCE button. Works well with custom post types as well as default post types.

Use the TinyMCE button to choose from a list of custom fields attached to the post to insert, or manually specify a custom field to display using the following syntax:

{%custom_field_name%}
