type “Alt+x org-mode”, then, type “Shift+Tab” to cycle thru levels of subsection hiding. Or, move cursor to particular heading, type “Tab” to do cycle on that particular level.

i just learned outline-mode this month, due to reading emacs 23's NEWs file.

in outline mode, type Alt+x describe-mode, and it'll spit out its inline doc. Then you can read all about the shortcuts for hiding header or text etc.

Quote:

Commands:
C-c C-n outline-next-visible-heading move by visible headings
C-c C-p outline-previous-visible-heading
C-c C-f outline-forward-same-level similar but skip subheadings
C-c C-b outline-backward-same-level
C-c C-u outline-up-heading move from subheading to heading

C-c C-t make all text invisible (not headings).
C-c C-a make everything in buffer visible.
C-c C-q make only the first N levels of headers visible.

however, the keys are exceedingly complex and their logic cumbersome, especially if you have cua-mode on, or if you also have your own keyboard customizations.

So, i went to emacswiki for some read up.

http://www.emacswiki.org/emacs/OutlineMode

which gives a very good intro about outline mode.

Then, i found out about outline-magic package by Carsten Dominik, which provides much better shortcuts and commands, so you simply use arrow keys to do various expanding/hiding of the headers, or just press tab to cycle thru the common pattern of toggling thru showing/hiding sub sections.

The name Carsten Dominik sounds familiar, and indeed, he's the author of org-mode, which i never used but did spend some time on in the past to vaguely recall it's outgrowth of outline-mode.

So, i did a hour of study or 2. Basically, my quick conclusion is that org-mode completely supplants outline-mode in features and quality.

just set your mode to org-mode, then just type tab key to hide/show headers or subsections. org-mode is robust and well maintained, so it's good to bet on. :D

you could put:
(defalias 'outline-mode 'org-mode)

hope this helps. :D
