2.6 Sparse trees
An important feature of Org-mode is the ability to construct sparse trees for selected information in an outline tree, so that the entire document is folded as much as possible, but the selected information is made visible along with the headline structure above it.(8) Just try it out and you will see immediately how it works.
Org-mode contains several commands creating such trees, all these commands can be accessed through a dispatcher:
- C-c / (
- This prompts for an extra key to select a sparse-tree creating command.
- C-c / r
- Occur. Prompts for a regexp and shows a sparse tree with all matches. If the match is in a headline, the headline is made visible. If the match is in the body of an entry, headline and body are made visible. In order to provide minimal context, also the full hierarchy of headlines above the match is shown, as well as the headline following the match. Each match is also highlighted; the highlights disappear when the buffer is changed by an editing command,(9) or by pressing C-c C-c. When called with a C-u prefix argument, previous highlights are kept, so several calls to this command can be stacked.
For frequently used sparse trees of specific search strings, you can
use the variable
org-agenda-custom-commands to define fast
keyboard access to specific sparse trees. These commands will then be
accessible through the agenda dispatcher (see section 10.2 The agenda dispatcher).
(setq org-agenda-custom-commands '(("f" occur-tree "FIXME")))
will define the key C-c a f as a shortcut for creating a sparse tree matching the string ‘FIXME’.
The other sparse tree commands select headings based on TODO keywords, tags, or properties and will be discussed later in this manual.
To print a sparse tree, you can use the Emacs command
ps-print-buffer-with-faces which does not print invisible parts
of the document.(10)
Or you can use the command C-c C-e v to export only the visible
part of the document and print the resulting file.
