Insert new heading with same level as current. If the cursor is in a plain list item, a new item is created (see Plain lists). When this command is used in the middle of a line, the line is split and the rest of the line becomes the new headline2.
Insert new TODO entry with same level as current heading.
In a new entry with no text yet, TAB will cycle through reasonable levels.
Promote/demote current heading by one level.
Promote/demote the current subtree by one level.
Move subtree up/down (swap with previous/next subtree of same level).
Refile entry or region to a different location. See Refile and copy.
Narrow buffer to current subtree / widen it again
When there is an active region (Transient Mark mode), promotion and demotion work on all headlines in the region.
If you do not want the line to be split,
customize the variable
