org-cycle

org-cycle is an interactive autoloaded compiled Lisp function in `org.el'.


(org-cycle &optional ARG)

TAB-action and visibility cycling for Org-mode.

This is the command invoked in Org-mode by the TAB key. Its main purpose
is outline visibility cycling, but it also invokes other actions
in special contexts.

- When this function is called with a prefix argument, rotate the entire
buffer through 3 states (global cycling)
1. OVERVIEW: Show only top-level headlines.
2. CONTENTS: Show all headlines of all levels, but no body text.
3. SHOW ALL: Show everything.
When called with two `C-u C-u' prefixes, switch to the startup visibility,
determined by the variable `org-startup-folded', and by any VISIBILITY
properties in the buffer.
When called with three `C-u C-u C-u' prefixed, show the entire buffer,
including any drawers.

- When inside a table, re-align the table and move to the next field.

- When point is at the beginning of a headline, rotate the subtree started
by this line through 3 different states (local cycling)
1. FOLDED: Only the main headline is shown.
2. CHILDREN: The main headline and the direct children are shown.
From this state, you can move to one of the children
and zoom in further.
3. SUBTREE: Show the entire subtree, including body text.
If there is no subtree, switch directly from CHILDREN to FOLDED.

- When point is at the beginning of an empty headline and the variable
`org-cycle-level-after-item/entry-creation' is set, cycle the level
of the headline by demoting and promoting it to likely levels. This
speeds up creation document structure by pressing TAB once or several
times right after creating a new headline.

- When there is a numeric prefix, go up to a heading with level ARG, do
a `show-subtree' and return to the previous cursor position. If ARG
is negative, go up that many levels.

- When point is not at the beginning of a headline, execute the global
binding for TAB, which is re-indenting the line. See the option
`org-cycle-emulate-tab' for details.

- Special case: if point is at the beginning of the buffer and there is
no headline in line 1, this function will act as if called with prefix arg
(C-u TAB, same as S-TAB) also when called without prefix arg.
But only if also the variable `org-cycle-global-at-bob' is t.
