Bug: return key does not show the subtree the first time on a newly opened org file

Bug: return key does not show the subtree the first time on a newly opened org file

[Wanrong Lin]

Hi,

I have the following in my org-mode configuration:

(setq org-return-follows-link t)

Also, by default my org files are in overview mode (folded) when opened.

Usually, if my cursor is at the beginning of a heading, I can use the 
return key to cycle the visibility of its subtree. However, this does 
not work when I open an org file and do it the first time (the return 
key will just insert a blank line before the heading). But after the 
first time, it works fine again.

Thanks a lot for looking into this.

Forgot to mention this:

To reproduce the bug, after opening an org file, don't do anything 
(don't even move the cursor),  just press the return key. I use 
"session.el", so when I open an org file, the cursor will go to the the 
position of my last change in the buffer, and I can arrange the point to 
be on a heading. If you don't use "session.el", here is another way to 
reproduce the bug:

Open a test org file "test.org" and put the following into it,

* TODO A 
Test                                                             :mytag:
  SCHEDULED: <2008-02-27 Wed>

*Close* the file, do a tag search on "mytag", in the search result  
press  "TAB"  key to jump to the "TODO A Test" heading, which should be 
folded. Press return key and you will see the failure. Do it again and 
it works.

This is about following links, no (un)folding subtrees...

AFAIK, <RET> doesn't (un)fold a subtree.  Maybe you mean the <TAB> key?
I guess I'm missing something...

Yes, but only with this setting will <return> key be added to the 
"org-mouse-map" key map, and be bound to "org-open-at-point" command 
under certain contexts (like on the leading stars of a heading). 
Further, "org-open-at-point" is advised by org-mouse.el, which will do 
"org-cycle" under certain contexts.

I did meant return key. See my comments above.

Thanks for your comments.

Yes, this is really an accidental feature by a sequence of events:

org-return-follow-link will add org-return to the mouse-map
org-mouse.el will activate the stars in a headline

I can reproduce the bug, but I have no idea what is causing this, it  
must be
something in the internal setup of Emacs keymaps in a new buffer,
I have no idea how to fix this or work around it.

Why in the world would you use RET for cycling instead of TAB?

Yes, there is an advice for this in org-mouse.el.  

I think we should remove it since org-mouse.el shouldn't change the
behavior of keystrokes (only the behavior of the mouse.)

That probably is true. But I have doubt that removing the advice itself 
and bind the key in some other place will really solve the problem. To 
me, it seems somehow the first time you open a org-file, some context is 
not recognized correctly and hence the key map is not activated. If I 
just execute a command, any command (like "C-g" which does nothing), and 
then press the return key, it will work. Is that puzzling? :-)

Because I discovered it and thought that was an official feature and got 
used to it from day 1. :-) I will try to use Tab from now on.

It *is* puzzling.  

I have a fix for this.  I'm testing it a few days more and will commit
it if it works okay.

Look forward to it. Although I am trying to get into the habit of using 
TAB, it won't hurt to have the old way working too. Thanks a lot.
