List of all Shortcodes Created with add_shortcode

Is it possible to write a function that would list out all the instance of add_shortcode()?

For example: A theme doesn’t have documentation or a shortcode generator to allow easy inserting of the theme’s shortcodes. I would like to have a function find all the add_shortcode’s in the theme and show them to me.

Any help is greatly appreciated.

Thank You.
