I've just updated my representation of the Scripting DOM API Documentation for InDesign CC 2018 (13).
The website supports copy & paste for every text where the copy icon appears while hoovering with the mouse.
You can find a short overview of the DOM here: http://www.indesignjs.de/auflage2/wp-content/uploads/2015/04/InDesign_Skripting_Kurzreferenz.pdf
In case you're interested in the creation process, have a look at the transformations at https://github.com/grefel/extendscriptApiDoc
A big THANK YOU towards jongware who inspired me with his version at http://jongware.mit.edu/ for the work!
Woo hoo! That's fast -- it's not even 2018 yet!
thank you very much for this!
