Expanding highlighted nodes

Expanding highlighted nodes

[T. Short]

Is there a way to expand highlighted nodes? I really like the tags tree (C-c \)
and the TODO tree (C-c C-v). After either of these, I'd like to expand
everything under the highlighted nodes.

Not really.  You might want to look into the new mapping API which  
would make it easy
to implement something like this.

Here's a way to expand highlighted areas that works with C-c \ and C-c C-v and
other highlighted sparse trees:

(defun org-expand-highlights ()
"Expand (cycle) highlighted tree nodes"
  (interactive)
  (dolist (highlight org-occur-highlights)
    (goto-char (overlay-start highlight))
    (org-cycle)))

Note that I barely know emacs lisp, so this may be clumsy. It appears to work
well enough for me. It does leave the node following highlighted.

Well, nice!  The only problem is hat it is an extra comment, and I  
don't have a good hook for you where to put this.  So you need to call  
two separate commands to make this happen.  If you don't mind this,  
then you are done.

If the matching entry has children, the org-cycle will only show the  
children's heading, not the whole subtree.  You might want to call it  
twice, or try a different approach using org-back-to-heading and org- 
show-subtree.

Thanks, Carsten. I like it as a separate command. Mostly, I like the plain
versions of C-c C-v (and friends) but like the idea of expanding as needed. And,
this seems to give me that.

I may play with that, but just having the children's headings is sufficient for
most of my org files.
