How to get Contex reveal work in org mode

Question

Having a hard time figuring out what C-c C-r does context reveal

Manual says "With a prefix argument show, on each level, all sibling headings. With a double prefix argument, also show the entire subtree of the parent."

1. When all the Headings are collapsed and I do C-c C-r on a Heading 1
   • nothing happens
2. If I try it on a Heading2 or Heading3 when it is collapsed
   • nothing happens

3. If I try C-u 2 C-c C-r on a second level heading

   • Do I get to see all Heading 2 siblings with the current heading fully expanded ?

   • How can I make this work ?

     • Or does this work only in agenda views or sparse trees only ?

Answer 1

Got it. its for sparse trees.

After C-c / when the cursor is on the the highlighted entry, C-c C-r works. :)
