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 it1. Just try it out and you will see immediately how it works.
Org mode contains several commands for creating such trees, all these commands can be accessed through a dispatcher:
For frequently used sparse trees of specific search strings, you can
use the option
org-agenda-custom-commands to define fast
keyboard access to specific sparse trees. These commands will then be
accessible through the agenda dispatcher (see 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. Or you can use C-c C-e C-v to export only the visible part
of the document and print the resulting file.
