Keep in mind my very limited emacs knowledge - but wouldn't it be possible to switch between modes depending where the cursor is? This would mean the buffer is in R-mode, when the cursor is in a R code block, and in org-mode, when the cursor is outside. One could even enable minor-org-mode to keep some functionality n the code blocks? I know this would not be ideal, but wouldn't that be possible?

When I click into the highlighted block, I an send to the indirect buffer. This behavior changes, after saving with C-s, even when nothing has been edited: the area in the original org file looses its magic, and looks normal again and can also be edited! The indirect buffer stays functional and, upon close via C-c ' saves the changes into the original buffer and *overwrites* changes done in this block in the org document. This is a bug which is difficult to fix in all generality. What should really happen is that the text in the original buffer is made read-only. But so far this does not happen in our implementation (due to Dan Davison IIRC). The reason for this is that read-only text properties left by accident in a buffer are difficult to get rid of. There are many things the user could go back and screw up the original. That's why Org choses to protect with highlighting with an overlay. Note that this is not a protection against editing, but it is a visual warning. I never knew that your goal was to make the code block read-only in the Org buffer. Note that I would be really opposed to such a change. Editing code in the prose would really become a pain to me -- please know that I NEVER use the indirect buffer. I only mean while there is a special buffer also editing this block! Pfff! I'm relieved -- I should have understood it ;-) Best regards, Seb -- Sebastien Vauban
