2.2.1 Global and local cycling
Outlines make it possible to hide parts of the text in the buffer. Org uses just two commands, bound to TAB and S-TAB to change the visibility in the buffer.
TAB (org-cycle)
Subtree cycling: Rotate current subtree among the states
,-> FOLDED -> CHILDREN -> SUBTREE --.
'-----------------------------------'
Point must be on a headline for this to work[^4].
S-TAB (org-global-cycle)
C-u TAB
Global cycling: Rotate the entire buffer among the states
,-> OVERVIEW -> CONTENTS -> SHOW ALL --.
'--------------------------------------'
When S-TAB is called with a numeric prefix argument N, view contents only up to headlines of level N.
Note that inside tables (see Tables), S-TAB jumps to the previous field instead.
You can run global cycling using TAB only if point is at the very beginning of the buffer, but not on a headline, and org-cycle-global-at-bob is set to a non-nil value.
C-u C-u TAB (org-set-startup-visibility)
Switch back to the startup visibility of the buffer (see Initial visibility).
C-u C-u C-u TAB (org-show-all)
Show all, including drawers.
C-c C-r (org-reveal)
Reveal context around point, showing the current entry, the following heading and the hierarchy above. It is useful for working near a location that has been exposed by a sparse tree command (see Sparse Trees) or an agenda command (see Commands in the Agenda Buffer). With a prefix argument, show, on each level, all sibling headings. With a double prefix argument, also show the entire subtree of the parent.
C-c C-k (org-show-branches)
Expose all the headings of the subtree, but not their bodies.
C-c TAB (org-show-children)
Expose all direct children of the subtree. With a numeric prefix argument N, expose all children down to level N.
C-c C-x b (org-tree-to-indirect-buffer)
Show the current subtree in an indirect buffer[^5]. With a numeric prefix argument N, go up to level N and then take that tree. If N is negative then go up that many levels. With a C-u prefix, do not remove the previously used indirect buffer.
C-c C-x v (org-copy-visible)
Copy the visible text in the region into the kill ring.
