In Komodo Edit 12, how to override the default syntax highlighting behavior of non-alphanumeric symbols?

I program in Forth and Komodo’s syntax highlighting has a behavior that I don’t want. It seems that it treats symbols like @ or > as a separate class of tokens. But because symbols in Forth aren’t special and can be included in function names I want to disable this behavior for just Forth. I know about the koForthLanguage.py file and have added several keywords but am frustrated by the incorrect highlighting I get where for example the word (as functions are known) >r is interpreted as the tokens > and r resulting in that it isn’t displayed in the color I set for the keywords >r is a part of.
