Collapsing the current outline in Emacs org-mode

Question

Say I am in org-mode in a document with the following structure:

* First headline 
* Second headline
** Section A
   Here is one line
   Here is another line
   blah, blah
** Section B

Say the cursor is on the line that reads Here is another line. I would like to collapse ** Section A from this location with a keyboard shortcut.

• If I press <TAB> it does not collapse ** Section A, as I would need the cursor to be on the stars for this to work.
• If I press <Shift-TAB> it collapses all outlines, and not the current one.

Is there any way to cycle through the collapsing of the outline in scope (i.e. the "current outline")?

Answer 1

You can customize the behaviour of the org-cycle command (which is bound to <TAB>) by changing the value of org-cycle-emulate-tab.

To get it to collapse ** Section A when your cursor is on Here is another line add the following line to your .emacs file:

(setq org-cycle-emulate-tab 'white)

The white will allow you to still use <TAB> to indent in empty lines. From org-mode Github:

org-cycle-emulate-tab's value is t

Documentation:
Where should `org-cycle' emulate TAB.
nil         Never
white       Only in completely white lines
whitestart  Only at the beginning of lines, before the first non-white char
t           Everywhere except in headlines
exc-hl-bol  Everywhere except at the start of a headline
