M-<RET>     (`org-insert-heading')
     Insert a new heading/item with the same level than the one at point.
C-<RET>     (`org-insert-heading-respect-content')
     Just like `M-<RET>', except when adding a new heading below the
     current heading, the new heading is placed after the body instead
     of before it.  This command works from anywhere in the entry.
M-S-<RET>     (`org-insert-todo-heading')
     Insert new TODO entry with same level as current heading.  See
     also the variable `org-treat-insert-todo-heading-as-state-change'.
C-S-<RET>     (`org-insert-todo-heading-respect-content')
     Insert new TODO entry with same level as current heading.  Like
     `C-<RET>', the new headline will be inserted after the current
     subtree.
<TAB>     (`org-cycle')
     In a new entry with no text yet, the first <TAB> demotes the entry
     to become a child of the previous one.  The next <TAB> makes it a
     parent, and so on, all the way to top level.  Yet another <TAB>,
     and you are back to the initial level.
M-<left>     (`org-do-promote')
     Promote current heading by one level.
M-<right>     (`org-do-demote')
     Demote current heading by one level.
M-S-<left>     (`org-promote-subtree')
     Promote the current subtree by one level.
M-S-<right>     (`org-demote-subtree')
     Demote the current subtree by one level.
M-S-<up>     (`org-move-subtree-up')
     Move subtree up (swap with previous subtree of same level).
M-S-<down>     (`org-move-subtree-down')
     Move subtree down (swap with next subtree of same level).
M-h     (`org-mark-element')
     Mark the element at point.  Hitting repeatedly will mark
     subsequent elements of the one just marked.  E.g., hitting <M-h>
     on a paragraph will mark it, hitting <M-h> immediately again will
     mark the next one.
