Hi All,

I tend to use a right arrow (→, U2192) from time to time in plain
lists to separate normal item from conclusions / next actions etc.:

  - Topic
    - Fact 1
    - Fact 2
    → Conclusion

I would appreciate it if org-mode could support this type of bullet
point.  The attached patch implements what I had in mind.

I'm not sure if the adaptation in /org-cycle-list-bullet/ is useful
for others --- I don't use the arrow for many items in a list, but
only single ones --- But I included it in the patch for completeness.

(Also, there may be better ways to encode unicode chars in regexp than
using the utf-8 encoding, that the patch uses.)

Cheers,
Martin

  Hi Martin,
  
  thank you for the patch.
  
  I will, however, not install it, at least not in the present form.
  
  Org-mode is hard-core plain text, and for me this also means that
  all the control parts that have special meaning should be plain
  ASCII characters.  The only exception is that tags are allowed
  contain characters specific for other languages.  So I do not
  want to hard-code a non-ASCII character in this way.
  
  I would consider a patch which introduces a variable listing
  the allowed bullet characters.  If you want to make such a patch,
  it will be a non-trivial patch and you would have to sign
  over copyright to the FSF so that I can include it.
  
  Sorry for making this so hard....
  
  One thing I would worry about is this:  Org sometimes normalized
  all bullets in a list to have the same bullet type.  This would
  interfere with your idea of having one special bullet in an
  otherwise normal list.  Has this never cause problems in your setup?
  
  - Carsten

    Hey, me too! I use exactly → to hightlight items, but also to mark implications (I use ∴ for conclusions); I have many keys for that type of useful symbols. :-) (or should I write ☺…?)

    However, I have done it always like this:
  
     - Topic
       - Fact 1
       - Fact 2
       - → Conclusion
  
    So it is still a list, but I know this item is special. In this way I can also use the symbol in headings:
  
  * some task
  ** option1
  ** → option2 (this is what I did)
  
  
    I still have to check org-choose.el, which provides a way to mark the chosen option between many alternatives in a more formal way.
  
    Greetings,
  
  Daniel

    This is, actually, a much better idea, so let's not go there
    and make the item bullets configurable.  It is possible that
    too much confusion will arrise from it.
    
    It is also, in my opinion, quite visible!  If you want to make
    it still more visible, you can try something like
    
    (font-lock-add-keywords 'org-mode
    '(("^\\([ \t]*[-*+]\\|^\\*+\\)[ \t]+→.*"
        0 font-lock-warning-face prepend)))

      This sounds reasonable, thanks.
