twig autocomplete variables

Hello,
I wonder whether it is possible to make automatic refill of the variables in the twig file.

For phpstorm I found something like this:
https://stackoverflow.com/questions/262 ... -twig-vars

However, I do not know how to call an opencart class in this way.

Would anyone know how to advise me how to do it?
Alternatively, advise the best IDE for opencart?

Use TextCrawler and look for the term: 'autocomplete' from the TWIG extension filter. It will provide all the answers.
