Yes, I suggested that in those cases, org-cycle should fold the subtree 
point is in, i. e. fold up to the next parent heading above.

Hm, for me, TAB does not currently seem to do any indenting anywhere in 
an Org file. Have you changed anything from the default configuration? 
Or maybe I did and forgot about it... But I can find any reference to / 
binding for unmodified tab in my init.el. If so, is this indenting 
handled by 'org-cycle' or is the binding of Tab to 'org-cycle' somehow 
selective based on where in an Org file point is positioned?

If people use tab for indentation in Org out of the box when not on 
headings (which it has never done for me, I think), my suggestion would 
indeed be moot.

> That said: C-c C-t or M-x outline-hide-body

I tried out this command, but it does not do what I have in mind 
(folding subtrees from a non-parent position, not hiding non-heading text).

If tab really does indent in Org files in the default configuration when 
not on a heading, I'd limit my suggestion to the following:

Make 'org-fold-hide-subtree' and / or 'outline-hide-subtree' work from 
anywhere inside a subtree that is not itself a parent heading - not just 
when positioned on the parent heading of the subtree point is in.

Best,

Philipp

They would have gotten an error.
I changed it now that 'nbb backend is still allowed in a clojure
source block but it will internally treated as ClojureScript.

I changed the docstrings to always mention either Clojure or ClojureScript.
I'm open for more improvements/suggestions.

Attached a new patch.

Thanks,

Subject: [PATCH] ob-clojure.el: Fix results output, support clojure-cli

* lisp/ob-clojure.el (org-babel-clojure-backend): Add support for
clojure-cli.
* lisp/ob-clojure.el (org-babel-clojurescript-backend): Move nbb to
clojurescript.
* lisp/ob-clojure.el (org-babel-expand-body:clojure)
* lisp/ob-clojure.el (ob-clojure-eval-with-cider): Return only the
last expression when :results is not set or value, and return only
stdout when :results is set to output.
* lisp/ob-clojure.el (ob-clojure-eval-with-cmd): Rename function as
it is not only for babashka.
* lisp/ob-clojure.el (org-babel-execute:clojure): Differentiate
between Clojure and ClojureScript source blocks.

The problem was that the ob-clojure results where not correctly
taking the results parameter into account.
E.g. with the cider backend, you would get all printed or returned
values for each line in your block:

(def small-map {:a 2 :b 4 :c 8})
{:some :map}
(prn :xx)
(:b small-map)

| #'user/small-map |
| {:some :map}     |
| 4                |

or for babashka you would only get the printed values but not the
last return value:
(def small-map {:a 2 :b 4 :c 8})
{:some :map}
(prn :xx)
(:b small-map)

: :xx

Now when you specify :results value, the result is only the last
returned value, and with :results output you get all values
printed to stdout.
So the examples above would all result in the same:
(def small-map {:a 2 :b 4 :c 8})
{:some :map}
(prn :xx)
(:b small-map)

: 4

Ups, I attached the wrong one.
Here the correct patch..

Subject: [PATCH] ob-clojure.el: Fix results output, support clojure-cli

* lisp/ob-clojure.el (org-babel-clojure-backend): Add support for
clojure-cli.
* lisp/ob-clojure.el (org-babel-clojurescript-backend): Move nbb to
clojurescript.
* lisp/ob-clojure.el (org-babel-expand-body:clojure)
* lisp/ob-clojure.el (ob-clojure-eval-with-cider): Return only the
last expression when :results is not set or value, and return only
stdout when :results is set to output.
* lisp/ob-clojure.el (ob-clojure-eval-with-cmd): Rename function as
it is not only for babashka.
* lisp/ob-clojure.el (org-babel-execute:clojure): Differentiate
between Clojure and ClojureScript source blocks.

The problem was that the ob-clojure results where not correctly
taking the results parameter into account.
E.g. with the cider backend, you would get all printed or returned
values for each line in your block:

(def small-map {:a 2 :b 4 :c 8})
{:some :map}
(prn :xx)
(:b small-map)

| #'user/small-map |
| {:some :map}     |
| 4                |

or for babashka you would only get the printed values but not the
last return value:
(def small-map {:a 2 :b 4 :c 8})
{:some :map}
(prn :xx)
(:b small-map)

: :xx

Now when you specify :results value, the result is only the last
returned value, and with :results output you get all values
printed to stdout.
So the examples above would all result in the same:
(def small-map {:a 2 :b 4 :c 8})
{:some :map}
(prn :xx)
(:b small-map)

I do not mind to have such feature as well. If you really want to get 
it, you should send a feature request to bug-gnu-emacs.

I expect that it should be implemented in Emacs core since updated 
`define-key' should be available rather early during initialization. 
Looking into
https://www.gnu.org/software/emacs/manual/html_node/elisp/Format-of-Keymaps.html
https://www.gnu.org/software/emacs/manual/html_node/elisp/Key-Lookup.html
I do not see a ready to use slot for location of key definition. Another 
point is that keymap extension should not noticeably affect performance.

Hi,

During discussion in the following thread I realized that the refcard 
was not updated when `org-force-cycle-archived' binding was changed from 
C-TAB to C-c C-<tab> to avoid conflict with switching of tabs.

what i meant was that i have a binding, org-next-link, bound to c-tab.

i acccomplished this with (define-key org-mode-map (quote [C-tab])
(quote org-next-link)) [kbd would be better].

i did similar with org-link-minor-mode.  i was just offtopicing that
it would be useful to jump to those definitions.

i.e. like m-. on a function name, if that is set up to work, or c-h f
command tab ret to go to the fuction definition, but for keys.

Well, sure -- we get that for free.

I think we can consider this proposal over.  While I find 
`org-fold-hide-subtree' very useful, the Org Mode default keyspace 
is very busy already, and we don't hear anyone proposing to drop 
something else in favor of `org-fold-hide-subtree'.  Anyone can 
custom-bind it themselves, of course (which is what I'll continue 
doing).

Agreed.

No, there is an explicit exception for C-g, see (info "(elisp) Key 
Binding Conventions") in "Tips and Conventions" appendix.

It might be a problem to distinguish C-i and <tab> in text terminal.

Even C-c C-x prefix is quite busy. Other modifiers might be a rescue: 
C-c M-something.

However perhaps M-x with fuzzy completion allowing typos (and ideally 
synonyms) might be a better solution.

No, [Ctrl+Tab] and [Ctrl+Shift+Tab] is widely used in other applications 
to switch to next/previous tabs. I would strongly prefer to keep it 
consistent across as much applications as possible. (There are corner 
cases like e.g. vim with multiple tabs running in a terminal application 
having several tabs as well. E.g. gnome terminal is able to pass 
[Ctrl+PgDn], a [Ctrl+Tab] alternative, while it has single tab, but 
intercepts the same shortcut when more terminal tabs are opened, so vim 
keys have to be used.)

C-h f org-next-link

displays at the top:

It is bound to C-c C-x C-n, <menu-bar> <Org> <Hyperlinks> <Next link>.

Is it the feature you are asking for? This one is available out of the box.

Unfortunately it is not trivial to discover binding from a file that is 
not loaded. Actually I found `tab-next' in the manual at first. Earlier 
attempts with "C-<tab>" and "C-TAB" failed due to "[(control tab)]" is 
used in tab-bar.el.

Okay, today I did some research and found that every "C-c 
C-<letter>" binding is used in Org Mode except for "C-c C-g". 
While that one is technically reserved for the mode's use, I 
suspect the reason it's unbound is that people are accustomed to 
using C-g as a quit command (and they get that effect if they 
accidentally type C-c, because then they type C-g and it's just an 
undefined key -- i.e., it quits, which is what the user wanted).

Note that while "C-c C-h" does not appear to be bound, it actually 
is: it gets you a help buffer about the Org Mode keybindings 
(which then, ironically, does not list "C-c C-h" as one of the 
bindings).

(It's not clear to me whether Emacs's conventions consider "C-c 
C-i" to be a letter or whether they treat "C-i" as "TAB" and 
consider it special; based on the previous evidence in this 
thread, maybe the latter, so we shouldn't consider "C-c C-i" to be 
available.)

I think what this is telling me is that Org Mode keybinding real 
estate is quite valuable :-), and that unless there are other 
people who feel as strongly as I do that `org-fold-hide-subtree' 
is amazingly useful, we probably won't decide to bind it by 
default in Org Mode.  So I should just continue to bind it to a 
custom key myself and continue to live a glorious life all alone 
in my private keymap splendour.

Ah, I don't use tab-bar at all (at least not as far as I know), so 
I'm not 100% sure what the above is saying.

Are you saying that the only current default binding for C-<tab> 
in Emacs is that one in tab-bar.el, and therefore we should feel 
free to rebind it in Org Mode?  If so, we should still be 
cautious, since Emacs has policies for maintaining the keybinding 
space.  Generally, the space "C-c C-<LETTER>" is reserved for 
major modes, so ideally we should find something in there if we 
can -- although Org Mode has used up a lot of that space already 
:-), so I'm not sure what's left, unless we decide to swap out 
some existing binding in favor of this one.

(I realize this contradicts what I said in my inital post.  I had 
forgotten that C-<tab> was not part of the mode-reserved space.)

Best regards,
-Karl

Minibuffer file cache completion should not be relevant to Org buffers.

Ah, clearly it is not a good choice -- thank you for noticing 
that.

I think there are two separate questions here:

1) Would it be useful to bind `org-fold-hide-subtree' by default?

2) If yes to (1), then is there a good key to bind it to?  (C-c 
C-something, I guess.)

If we agree on (1), then let's figure out the answer to (2).  I 
don't know if anyone else agrees about (1) yet, though.

By the way, the binding in my Org Mode hook looks like this:

  (when (not (keymap-lookup nil "C-<tab>"))
    (keymap-local-set "C-<tab>" 'org-fold-hide-subtree))

So FWIW C-<tab> is not bound in Org Mode buffers for me, in Emacs 
30.x (i.e., recent development builds).  However, I agree with 
Bastien's logic: C-<tab> is not in the reserved keymap space, so 
Emacs might bind it (and perhaps does bind it in other modes).

I don't know how widely-used `org-cycle-force-archived' is (that's 
the new name of that function).  I don't use it, personally, so if 
we decide against (1)+(2) above, then perhaps I'll just override 
that binding for myself instead.

Best regards,
-Karl

Hey everyone, is there a reason we don't bind 
`org-fold-hide-subtree' by default in Org Mode?

I bind it to C-<tab> and now find this to be one of the most 
useful keybindings in Org Mode.  I suspect my workflow is pretty 
typical.

The use case is simple:

When reading material within a certain heading level, one often 
decides that one is done with that section (and therefore done 
with everything inside it -- including anything at deeper levels 
of nesting).  So one just folds the entire subtree around point 
and moves on, without changing the visibility of any of the 
sibling-or-higher subtrees around it (because often the next place 
one is going is one of them).

This is one of my most frequent actions in Org Mode.  In fact, I 
think it might be the most common Org Mode command I run.

It seems like an obvious thing have bound to a key, and yet Org 
Mode doesn't bind it by default.  Should we?

(I put it on "C-<tab>" because that's normally unbound in Org 
Mode, and because so many of the Org Mode cycling commands involve 
modified tab already.  But I don't feel strongly about the 
particular key, as long as it's fast to type; maybe there's a 
better key available.)

I looked for prior discussion about this in the archives and 
didn't find anything:

It says that the new folding backend won't work with outline.el. But
in this case, I am still using the old backend.
Are the outline.el functions expected to stop working for the old backend too?

I replaced hide-subtree with org-fold-hide-subtree and my subtree
collpasing function seems to work as before even with
org-fold-core-style set to 'overlays. I will update this thread if I
see any issue with that.

Thanks!

I'd say that it is org-core issue. The current behaviour does not really
follow what org-fold-show-entry docstring promises:

>> Show the body directly following its heading.

>> Show the heading too, if it is currently invisible.

In fact, forcefully folding the drawers is relatively recent addition by
Nicolas in 1027e0256903bc2.

I am attaching the patch making drawer folding controllable via optional
argument. WDYT?

Best,
Ihor

Subject: [PATCH] org-fold-show-entry: Do not fold drawers unless requested

* lisp/org-fold.el (org-fold-show-entry): Do not fold drawers in the
unfolded entry unless the new optional argument is non-nil.  Folding
the drawers was introduced in 1027e0256903bc2, but does not follow the
function docstring.  Moreover, folding drawers creates unexpected
behaviour in some cases.  See
https://orgmode.org/list/m2a6bl4mmr.fsf@andrew.cmu.edu

* etc/ORG-NEWS (~org-fold-show-entry~ does not fold drawers by default
anymore): Document the change.

* lisp/org-agenda.el (org-agenda-show):
(org-agenda-show-and-scroll-up):

* lisp/org-clock.el (org-clock-goto):
* lisp/org-compat.el (outline-toggle-children):
* lisp/org-timer.el (org-timer--get-timer-title):
* lisp/org.el (org-move-subtree-down):
(org-return): Explicitly request folding drawers inside the revealed
entry in the places where it appears to make sense.

Thanks for the heads up! This was just a blind kill-yank from a macro
with extra arg.

Still, it needs to be done.
Attaching the patch with fixed indent statements and reindented code.

Best,

+;;; Commentary:
+
+;; This file contains code handling temporary invisibility (folding
+;; and unfolding) of text in org buffers.
+
+;; The folding is implemented using generic org-fold-core library.  This file
+;; contains org-specific implementation of the folding.  Also, various
+;; useful functions from org-fold-core are aliased under shorted `org-fold'
+;; prefix.
+
+;; The following features are implemented:
+;; - Folding/unfolding various Org mode elements and regions of Org buffers:
+;;   + Region before first heading;
+;;   + Org headings, their text, children (subtree), siblings, parents, etc;
+;;   + Org blocks and drawers
+;; - Revealing Org structure around invisible point location
+;; - Revealing folded Org elements broken by user edits

+
+\\<org-mode-map>Some actions may move point into invisible
+locations.  As a consequence, Org always exposes a neighborhood
+around point.  How much is shown depends on the initial action,
+or context.  Valid contexts are
+
+  agenda         when exposing an entry from the agenda
+  org-goto       when using the command `org-goto' (`\\[org-goto]')
+  occur-tree     when using the command `org-occur' (`\\[org-sparse-tree] /')
+  tags-tree      when constructing a sparse tree based on tags matches
+  link-search    when exposing search matches associated with a link
+  mark-goto      when exposing the jump goal of a mark
+  bookmark-jump  when exposing a bookmark location
+  isearch        when exiting from an incremental search
+  default        default for all contexts not set explicitly
+
+Allowed visibility spans are
+
+  minimal        show current headline; if point is not on headline,
+                 also show entry
+
+  local          show current headline, entry and next headline
+
+  ancestors      show current headline and its direct ancestors; if
+                 point is not on headline, also show entry
+
+  ancestors-full show current subtree and its direct ancestors
+
+  lineage        show current headline, its direct ancestors and all
+                 their children; if point is not on headline, also show
+                 entry and first child
+

+                 their entries and children; if point is not located on
+                 the headline, also show current entry and all children
+
+As special cases, a nil or t value means show all contexts in
+`minimal' or `canonical' view, respectively.
+
+Some views can make displayed information very compact, but also
+make it harder to edit the location of the match.  In such

+;;; Commentary:
+
+;; This file contains code handling temporary invisibility (folding
+;; and unfolding) of text in org buffers.
+
+;; The folding is implemented using generic org-fold-core library.  This file
+;; contains org-specific implementation of the folding.  Also, various
+;; useful functions from org-fold-core are aliased under shorted `org-fold'
+;; prefix.
+
+;; The following features are implemented:
+;; - Folding/unfolding various Org mode elements and regions of Org buffers:
+;;   + Region before first heading;
+;;   + Org headings, their text, children (subtree), siblings, parents, etc;
+;;   + Org blocks and drawers
+;; - Revealing Org structure around invisible point location
+;; - Revealing folded Org elements broken by user edits

+\\<org-mode-map>Some actions may move point into invisible

+
+As special cases, a nil or t value means show all contexts in
+`minimal' or `canonical' view, respectively.
+
+Some views can make displayed information very compact, but also
