. . . I'm getting confused about how to use these features. Sometimes, by chance, I'll find an example/use. but often as not I'm looking at a raw reference dump with no clue how to use (best practices) these features. For example, org-id has http://orgmode.org/worg/org-api/org-id-api.html but no real explanation on what it is or how to use it. Googling doesn't bring anything either. in-buffer settings (http://orgmode.org/manual/In_002dbuffer-settings.html#In_002dbuffer-settings) is fairly cryptic for me too. Sometimes I can figure out what's going on, but I'm far from having a "best use" understanding. For example, I can look at the "source" for at WORG page (http://orgmode.org/worg/worg-setup.org.html) and see:

#+STARTUP: align fold nodlcheck hidestars oddeven lognotestate

#+SEQ_TODO: TODO(t) INPROGRESS(i) WAITING(w@) | DONE(d) CANCELED(c@)

#+TAGS: Write(w) Update(u) Fix(f) Check(c)

#+TITLE: Worg setup on the http://orgmode.org server

#+AUTHOR: Worg people

#+EMAIL: mdl AT imapmail DOT org

#+LANGUAGE: en

#+PRIORITIES: A C B

#+CATEGORY: worg

#+OPTIONS: H:3 num:nil toc:nil \n:nil ::t |:t ^:t -:t f:t *:t tex:t d:(HIDE) tags:not-in-toc

I can then sift through the reference "in-buffer settings," but I'm not much wiser on the whytofors. Has anybody, tutorial-wise, really sorted these concepts out properly?

One task I'd like to have is the ability to embed keywords throughout an org file so that a parser can find and grab these sections. I'm assailed with seemingly many ways: PROPERTIES, org-element, org-id, tags -- most/all of which I have only the dimmest grasp.

Thanks,
