Hi to all,
I copied an orgmode setup from http://www.newartisans.com/2007/08/using-org-mode-as-a-day-planner.html in order to test the described way of GTDing there. Since it works fine for me, I am trying to understand, what's going on beyond the surface. I found the expression above in the setup elisp file. After examining the manual and serveral sites, I still don't understand the term [?a] within that statement. Can anybody brighten my mind?
Thank you all!

I assume you are referring to the following line?
(define-key mode-specific-map [?a] 'org-agenda)
This line binds org-agenda to "C-c a". (You can checkout the
documentation for mode-specific-map by typing "C-h v
mode-specific-map").
The org-manual suggests the following line, which does the same thing:
(global-set-key "\C-ca" 'org-agenda)
Best,
Matt

The square brackets say it's a vector, and ?x is the reader-syntax for
characters. So it's a vector with exactly one item, the character `a'.
So this statement binds the command `org-agenda' to the key `a' in the
keymap `mode-specific-map'.
You could have written any of the following with equal results:
(define-key mode-specific-map "?a" 'org-agenda)
(define-key mode-specific-map (kbd "a") 'org-agenda)
I prefer the `kbd' version. That understands the keybinding syntax that
is displayed in `C-h k', and which is used in all manuals, too.
