Highlight special string

Highlight special string

[Karl Maihofer]

Hi,

I don't know if this is an Org- or Emacs-Question. For highlighting  
special strings in AucTeX I used a variable  
"font-latex-user-keyword-classes" so I thought there may be an  
org-specific variable to achieve what I want in orgmode.

I'd like to highlight the strings "(ok)" and "(fail)" in my  
Org-document. Ok should get a green background, fail a red one. I  
think highlighting in emacs should last, but it would be great to have  
these strings highlighted in HTML-export, too, if this is no problem.

Could anybody give me a hint how to define highlighting for special  
strings in orgmode?

Thanks a lot!
Karl

Not exactly what you want, but for temporary highlights (useful for
instance to see if you are repeating the same word too much in a text) you
can use hi-lock-mode.

Turn hi-lock-mode on with M-x hi-lock-mode. Then you can highlight a word
with "C-x w h" (highlight-regexp) or a the line containing a word with "C-x
w l" (highlight-lines-matching-regexp). Remove highlights with "C-x w r".

Please find the *lasting* solution that I'm using, hence IMHO better than
hi-lock.

The only thing you would still miss is the ability to get those highlighted
words exported to HTML or PDF.

        (add-hook hook 'fontify-keywords))
#+end_src

As signaled in my comments, the only problem I have is that when such a word
appears in a Org heading, the Org heading fontification is disabled -- only
for that single line!

Would someone be able to fix that last tiny feature...

Best regards,
  Seb
