[O] org+cua "C-c ;" on selected region

[Martin Gross]

Hello

I am sorry if this has been answered before, but my google
research was not very successful.

When the cua-mode is enabled and I try to select a region to comment
it via "C-c ;" the selection is just copied, but not commented.  With
auctex-mode I use "C-c C-c ;" to do this and it works well.  ¿How can
I get the same behavior on org-mode?

Thank you very much in advance!

Martin
