When to use header arguments in org file?
For example, when you want to tangle all source blocks in an Org file, include the line: Before, **header arguments** could also be specified as **separate properties** (`#+PROPERTY: tangle yes`, for example), but that syntax has been **deprecated** in the commit `90b16870` of 2013-06-23 as that was slower to fetch block properties.
What happens when multiple source code blocks tangle?
When multiple source code blocks tangle to a single file with different and conflicting ‘ tangle-mode ’ header arguments, Org’s behavior is undefined. By default Org expands code blocks during tangling.
How to extract source code from a tangled file?
This hook is run from within code files tangled by org-babel-tangle, making it suitable for post-processing, compilation, and evaluation of code in the tangled files. Debuggers normally link errors and messages back to the source code.
How to use cmdline header argument in Babel?
The :cmdline header argument is supported by a couple of languages. For shell, this allows to make the code inside a Babel code block similar to a real shell script.

How to create new heading in org mode?
If you do not want the line to be split, customize org-M-RET-may-split-line .

With a double C-u C-u prefix, the new heading is created at the end of the parent subtree instead.
How to make a list into a headline in Emacs?
Narrow buffer to current subtree. Narrow buffer to current block. Widen buffer to remove narrowing. Turn a normal line or plain list item into a headline—so that it becomes a subheading at its location. Also turn a headline into a normal line by removing the stars. If there is an active region, turn all lines in the region into headlines.
How to select a region of a headline?
To select a region of headlines, it is best to place both point and mark at the beginning of a line, mark at the beginning of the first headline, and point at the line just after the last headline to change. Promote the current subtree by one level. Demote the current subtree by one level.
