This is the official manual for the latest Org-mode release.
Use C-c ' to edit the current code block. This brings up a language
major-mode edit buffer containing the body of the code block. Manually
saving this buffer with <C-x C-s> will write the contents back to the Org
buffer. You can also set
org-edit-src-auto-save-idle-delay to save the

<lang>is the language named in the header line of the code block, then the edit buffer will be placed in that major-mode. This variable can be used to map arbitrary language names to existing major modes.
nil, which means that when code blocks are evaluated during export or tangled, they are re-inserted into the code block, which may replace sequences of spaces with tab characters. When non-nil, whitespace in code blocks will be preserved during export or tangling, exactly as it appears. This variable is especially useful for tangling languages such as Python, in which whitespace indentation in the output is critical.
