Custom Grammar's Syntax Highlighting

Hi there,

The page creating-a-grammarlink does not show the full syntax highlighting less keys list. And the page doesn’t say anything about it.

scopes:
  'call_expression > identifier': 'entity.name.function'

I mean, the full list of something like entity.name.function.
After search a lot , I have found this page, https://github.com/atom/one-dark-syntax/blob/master/styles/syntax/_base.less. And after test, it works.

Now , I guess the less keys is a part of theme.

Sorry for my poor English.
I share this for someone who need this.

Update1:

The Example Packages is helpful.

e.g: lots of values in https://github.com/atom/language-javascript/blob/master/grammars/tree-sitter-javascript.cson works.
