Re: [RFC] C-c C-c in agenda

[Samuel Wales]

i think it can be confusing to new users to have column mode
accidentally activated.  what are the things they will try to get out
of it?  maybe worth considering all the panic commands they'd try, and
either deactivate or message what to do to deactivate?

if c-c c-c is being weighed, maybe consider it as one of those things
to possibly tip the balance?  i do not use column mode (drawers are
slow, too disorrganized to make a contact list with it), so cannot
say.

some things they might try are: q, c-c c-c, c-c c-k, esc esc esc, c-g,
undo, whatever they tried last, c-u on whatever they tried last,
revert, kill buffer, ? as a speed command, look at mode line, skim the
manual [for what?], c-z, whatever vim does, spacemacs?.

similar for things like outline search view and org agenda restriction
lock, but in my experience, those are less commonly accidentally
activated.
