hard question – HELP

Hi
I’m trying to change the behavior of the wordpress editor. To do that I need to know the var $_GET[“action”] in the following file: wp_path/wp-includes/js/tinymce/tiny_mce_config.php

Let me explain this better – the var $_GET[“action”] is present in the URL when we hit “edit” post/page.

Resume: with this I’ll know if we are writing a new post or editing a post.

If you need more details to help me please ask.

Thanks
