Emacs; How can I only display the current task and hide others in org-mode?

Question

Org mode.
I have a large task tree, and I want to select only 1 in the buffer (write notes only for him) and hide others during editing.
How can i do this?

task-1 subtask-1.1 subtask-1.2 task-2 subtask2.1 ... ... 

For example, I want to display only for me:

 subtask-1.2 (notes for this subtask) 

Answer 1

Use the narrow-to-defun or org-narrow-to-subtree to org-narrow-to-subtree point. ( widen to return to the contents of the entire buffer).

Default hotkeys:

 Cx ns # org-narrow-to-subtree (bound in org-mode) Cx nd # narrow-to-defun Cx nw # widen
