The first application of custom searches is the definition of keyboard shortcuts for frequently used searches, either creating an agenda buffer, or a sparse tree (the latter covering of course only the current buffer).
Custom commands are configured in the variable
org-agenda-custom-commands. You can customize this variable, for
example by pressing C-c a C. You can also directly set it with Emacs
Lisp in .emacs. The following example contains all valid agenda
(setq org-agenda-custom-commands '(("x" agenda) ("y" agenda*) ("w" todo "WAITING") ("W" todo-tree "WAITING") ("u" tags "+boss-urgent") ("v" tags-todo "+boss-urgent") ("U" tags-tree "+boss-urgent") ("f" occur-tree "\\<FIXME\\>") ("h" . "HOME+Name tags searches") ; description for "h" prefix ("hl" tags "+home+Lisa") ("hp" tags "+home+Peter") ("hk" tags "+home+Kim")))
The initial string in each entry defines the keys you have to press after the dispatcher command C-c a in order to access the command. Usually this will be just a single character, but if you have many similar commands, you can also define two-letter combinations where the first character is the same in several combinations and serves as a prefix key113. The second parameter is the search type, followed by the string or regular expression to be used for the matching. The example above will therefore define:
as a global search for agenda entries planned114 this week/day.
as a global search for agenda entries planned this week/day, but only those
with an hour specification like
[h]h:mm—think of them as appointments.
as a global search for TODO entries with ‘WAITING’ as the TODO keyword
as the same search, but only in the current buffer and displaying the results as a sparse tree
as a global tags search for headlines marked ‘:boss:’ but not ‘:urgent:’
as the same search as C-c a u, but limiting the search to headlines that are also TODO items
as the same search as C-c a u, but only in the current buffer and displaying the result as a sparse tree
to create a sparse tree (again: current buffer only) with all entries containing the word ‘FIXME’
as a prefix command for a HOME tags search where you have to press an additional key (l, p or k) to select a name (Lisa, Peter, or Kim) as additional tag to match.
Note that the
*-tree agenda views need to be called from an
Org buffer as they operate on the current buffer only.
You can provide a description for a prefix key by inserting a cons cell with the prefix and the description.
here that these entries have some planning information attached to them, like
a time-stamp, a scheduled or a deadline string. See
org-agenda-entry-types on how to set what planning information will be
taken into account.
