Custom Wordpress Editor?

After looking around for hours I couldn't see anything even close to what I saw here: http://www.youtube.com/watch?v=Y2Bu5NoYZ7M&feature=player_embedded

As you can see, they created a custom editor for Wordpress (not just some edits to TinyMCE), its a whole different editor even with an option to switch back to TinyMCE.

Does anyone kn开发者_如何学Cow how to create custom editors for wordpress without altering the core files and just via a custom theme? I am starting to think its a custom meta box...but I am not sure.

Any clue will be much appreciated!

I suggest to use a plugin to extend the default tinymce WP uses.. Take a look at this plugin: http://wordpress.org/extend/plugins/wp-super-edit/screenshots/

If you really want a completely different editor, ckeditor is quite ok.. There is a plugin too: http://wordpress.org/extend/plugins/ckeditor-for-wordpress/screenshots/

Always use or write a plugin an don't change any core files is indeed the way to go!

Please let me know what you think!
