Quick help when pressing '?' in an agenda view?

[Nathaniel W Griswold]

I noticed that org-agenda-mode stands out in that '?' is not bound to open some 
kind of help by default. Org agenda is unique in this, it is the first out of 
many views i have used that did not have '?' bound to open some kind of help. 
Seems to be convention in pretty much anything builtin to emacs or added by 
third party that takes over a buffer and interacts with the user. Some examples 
of builtin are dired, list-buffers, ibuffer, list-bookmarks.

'?' is currently default `org-agenda-show-the-flagging-note`, i haven't used 
that quite yet.

There hasn't been much discussion on the list about this, There was brief 
discussion on the list about 'h' here: 
https://orgmode.org/list/87v9b6qn23.fsf@gmail.com/. Maybe most people don't 
really care about this. Do other people ever use '?' or was that just me 
because i came from the vim world? It was something that stood out to me when i 
first started using org-mode, so i thought i would present it to the list as 
feedback data.

I didn't realize for a while that "C-h m" opens describe-mode by default, and 
describe-mode is kinda what i wanted for my problems. I had been opening the 
org info manual, taking a couple steps to navigate to 'Agenda Commands', and 
referencing that. I then bookmarked it because i was doing it so much. Maybe i 
was being stupid but i was new to stuff and i think the '?' is intended for 
people who are getting started and it would have helped me out there.

Anyway, just some thoughts.

Thank you, everyone. Great work on the software.
