Hi, a really good code editor which has a lot of ability.  
How i can use apply as “info” or how i can add the class for using highlighting?

You’re going to have to formulate your question a bit more precisely. I don’t understand it in its current form.

Actually, I did not understand my question too,  
But working with Lezer helped to understand how to work with visualization / highlighting.  
Because previously I tried to use “apply” as “info” from the interface Completion  
( tried to use Node for adding class and styles )
