Bug with cua-mode & org-support-shift-select

Bug with cua-mode & org-support-shift-select

[Ivan Vanyushkin]

Hello.

I want to use C-x/C-c/C-v and Shift-arrows selection with org-mode.

GNU Emacs 23.1.50.1, org-mode 6.34, .emacs:
(cua-mode 1)
(setq org-support-shift-select t)

If this two options are on, then Shift key selection with arrow keys 
doesn't work: no selection, just cursor movements. According to 
http://orgmode.org/manual/Conflicts.html I think that org-mode should 
support CUA. If not, what can you suggest for correct support of 
C-x/C-c/C-v + org-support-shift-select?

As far as I can say, the reason of problem is there:

In org.el:
(defun org-call-for-shift-select (cmd)
   (let ((this-command-keys-shift-translated t))
     (call-interactively cmd)))

Called like this: (org-call-for-shift-select 'forward-char)

In cua-base.el Shift key is detected like this:
     (memq 'shift (event-modifiers
               (aref (this-single-command-raw-keys) 0)))
binded as pre-command-hook.

So, I think, Shift key is just not detected by CUA, and need a way to 
set it's flag. Sorry, I don't know emacs lisp.

Thank you for your suggestions.

Vanilla emacs now has shift selection (as of version 23?), so try
disabling shift select in CUA and enabling the standard shift select.

M-x customize-variable shift-select-mode

Re: Bug with cua-mode & org-support-shift-select

I see no way to disable shift-select handling in CUA.

CUA on initializing disables shift-select-mode, and also if try to 
enable later, we got bug 
http://emacsbugs.donarmstrong.com/cgi-bin/bugreport.cgi?bug=4249 :

<citation>
CUA mode and shift-select-mode don't seem to be aware of each other.

If I turn on CUA first, and then shift-select-mode, shifted selection
fails (e.g. shift-right marks only one character as region).

Emacs -Q
(cua-mode 1)
(setq shift-select-mode t)

Why would one want to do that?
For example in order to get org-mode to work correctly with shifted
selection and the appropriate org-mode customization variable.

The fact that org-mode doesn't understand CUA's shifted selection is a
bit sad, too.
</citation>

So need some other way to fix this.
