How to add token for syntax highlighting in Komodo Edit 12?

Question

Code editor

I used to write in the Nim programming language (formerly Nimrod) in Sublime Text 3 . Friends advised me to try Komodo Edit . There is very little support for Nim, only a small part of the tokens are highlighted. In the color scheme editor, you can change the highlight, but I did not find how to add new words for highlighting.
Do you know how to add new tokens for highlighting?
