What is PrimeFaces p: editor based?

I want to add some client side functionality to PrimeFaces p: editor , but for some reason I am unable to expose the client side JavaScript code they used to build the component. Can anyone point me to this?

PS the two things I want to do is make the component mutable (PrimeFaces does not support this) and I want to add shortcut buttons for pasting preprogrammed text. Any hints on how this will be done would be appreciated.
