feature request: C-k safety

feature request: C-k safety

[Scott Otterson]

[-- Attachment #1.1: Type: text/plain, Size: 876 bytes --]

For what must be the dozenth time, I've just accidentally deleted a large
tree by typing C-k while in a headline.

This is really easy to do because emacs users have "C-k deletes to the end
of the line" worn deeply into their neural pathways -- it's so automatic for
me that the keystroke is close to subconscious.  A mistaken C-k is
especially hard to detect because org-mode displays the result exactly like
what your subconscious expects, that is, a collapsed headline is deleted to
the end -- and the tree underneath is wiped out with no noticeable warning.

Feature request: add an option preventing tree deletion with C-k without
user confirmation.  Actually, I'd like an option to prevent it period.

If this option is already in there, then you're encouraged to tell me to
RTFM.  But then also please tell me where it is, because I can't find it.

Thanks much,

Scott

Scott,

In the FAQ, you can find this:

(setq org-special-ctrl-k t) before losing your work.

It's a clever compromise, though I suspect it doesn't give as much
protection as you want.

Here's what it does. From the docstring:

When t, the following will happen while the cursor is in the headline:

- When the cursor is at the beginning of a headline, kill the entire
  line and possible the folded subtree below the line.
- When in the middle of the headline text, kill the headline up to the tags.
- When after the headline text, kill the tags.

Hi Scott,

OK, I am giving you a variable org-ctrl-k-protect-subtree to get this  
protection, either with a query or by throwing an error.

But:  my prediction is that you will set this variable to nil again  
soon :D

Let me know how it goes.

Cheers

- Carsten

Scot, Anthony and Carsten,

Thanks a ton for the help (and mods).  I'll try out these two approaches to
protecting me from myself and see which one I like best.

LoL!
Actually, I think is a gread idea, and I will test it also.  Probably error
will
be much better than query. Thank you Scott and Carsten.
Greetings
