Org can select items based on various criteria and display them in a separate
buffer. Six different view types are provided, one of which is agenda: like a
calendar and shows information for specific dates. The extracted information is
displayed in a special agenda buffer.
The information to be shown is normally collected from all agenda
files, the files listed in the variable org-agenda-files. If a
directory is part of this list, all files with the extension .org
in this directory will be part of the list. Add and remove files
from this list using C-c [ and C-c ].

The views are created through a dispatcher, which should be bound to a
global key—for example C-c a. After pressing C-c a, an additional letter is required
to execute a command. a produces a calendar-like agenda view. t produces a list of
TODO items. m produces headlines matching a TAGS expression. There are others as
well. See Agender Dispatcher.
