Hi

I am using org-babel to write a simulation model and the accompanying
documentation and it works as expected. But I have many source blocks which
I want to tangle into the same source file. At the moment, I am using
"#+source: BLOCKNAME" (see below). But it is easy to forget to add the block
name to the actual tangle block at the bottom. Is there a way of:

1) tangle all source blocks into the same file? As far as I am aware, a new
tangle to the same file name, overwrites the already existing file --- I
would like to append the new code block to the existing file.

or

2) is there a keyboard shortcut, that I can add the name of the block to the
actual tangle block automatically, when the e.g. block name is selected?

Thanks,

Rainer
* Here I am doing this
#+source: Block1
#+begin_src R
  some code
#+end_src

* Here I am doing that
#+source: Block2
#+begin_src R
  some code
#+end_src

* Creation of Source.R
#+begin_src R :tangle source.R
  <<cBlock1>>
  <<cBlock2>>
#+end_src
