This is the official manual for the latest Org-mode release.
Another possibility is the construction of agenda views that comprise
the results of several commands, each of which creates a block in
the agenda buffer. The available commands include
agenda for the
daily or weekly agenda (as created with C-c a a),
for the global TODO list (as constructed with C-c a t), and the
matching commands discussed above:
tags-todo. Here are two examples:
(setq org-agenda-custom-commands '(("h" "Agenda and Home-related tasks" ((agenda "") (tags-todo "home") (tags "garden"))) ("o" "Agenda and Office-related tasks" ((agenda "") (tags-todo "work") (tags "office")))))
This will define C-c a h to create a multi-block view for stuff you need to attend to at home. The resulting agenda buffer will contain your agenda for the current week, all TODO items that carry the tag ‘home’, and also all lines tagged with ‘garden’. Finally the command C-c a o provides a similar view for office tasks.
