I use org-mode to handle my tasks and projects in multiple files.
In the weekly agenda, it is possible to jump to the location of each TODO entry using <TAB> or <RET>. If the target file was not previously open, it is loaded an the cursor is set to the correct headline and the entire document is unfolded, including drawers.
I would very much prefer to see only a sparse tree with everything but the correct headline folded (subtree visibility does not matter).
It is possible to collapse the entire tree by cycling global visibility using C-u <TAB, but then I have to find the heading again.
I know I can hide the rest by narrowing the buffer as described here: Emacs, How can I display only current task and hide others in org-mode? but then I loose context (parent heading, easy access to siblings) and the drawers are still open.
Ideally, I would like to have a command that shows the following:
Edit:
A slighty modified version of the functions user3173715 posted seems to do the trick:
(defun org-show-current-heading-tidily ()
"Show next entry, keeping other entries closed."
(if (save-excursion (end-of-line) (outline-invisible-p))
(progn (org-show-entry) (show-children))
(outline-back-to-heading)
(unless (and (bolp) (org-on-heading-p))
(org-up-heading-safe)
(hide-subtree)
(error "Boundary reached"))
(org-overview)
(org-reveal t)
(org-show-entry)
(show-children)))
Check your org startup options (customize-group > org-startup) like org-startup-folded or org-agenda-inhibit-startup (others have mentioned these already) and set the options to show only the folded view. Org mode variables like #+STARTUP are discussed here.
You may notice that everything is folded when you now jump to the agenda, even the parents of the active item may not be visible. You can then make the context (parents, children, next sibling) visible with org-reveal (C-c C-r as per the manual)
