[NTG-context] Custom highlight ConTeXt syntax in AUCTEX

[NTG-context] Custom highlight ConTeXt syntax in AUCTEX

Dear All!
I've been using emacs AUCTEX for quite a while and found it very convenient
to work with.

One issue is the lack of syntax highlighting.

I've tried some elisp code and added the following hook when I'm in
ConTeXt-mode:

(add-hook 'ConTeXt-mode-hook
          (lambda ()
            (font-lock-add-keywords nil
                                    '(("\\(\\\\starttext\\)\\>" 1
font-lock-warning-face t)
                                      ("\\(\\\\stoptext\\)\\>" 1
font-lock-warning-face t)))))

and it seems to highlight the start-stop text keyword.

So my question is:
Is there a way to accomplish a similar way of highlighting all other
keywords that belongs to the ConTeXt typesetting syntax?

Maybe a REGEXP (I'm not good at writing those) can do this in some way
without manually write every start-stop sequence that exists.

Have anyone, using AUCTEX, already did some customizing already who wants
to share it with me.

Many thanks in advance

/Jan-Erik

https://wiki.contextgarden.net/Text_Editors says, Emacs has ConTeXt 
support including syntax highlighting.

I don’t use Emacs, so I don’t know how to activate/configure it.
Maybe it expects a different file extension, like .ctx?

It does not highlight e.g \starttext keyword by default. The colorscheme seems adapted to LaTeX mode so I managed to fix this now for all \start - \stop commands with this code put in ~/.emacs.d/init.el

(add-hook ’ConTeXt-mode-hook
        (lambda ()
                 (font-lock-add-keywords nil
                               ’((”\\(\\\\start\\w*\\)\\>” 1 font-lock-function-name-face t)
                                  (”\\(\\\\stop\\w*\\)\\>” 1 font-lock-function-name-face t)))))

And the regexp was done with help from interactive inbuilt function re-builder in emacs

The next goal is to highlight variabels like \textwidth for example

Thanks for feedback
