Probably not what you want but, assuming that the keys you hit are
always the same, you could always define a keyboard macro, name it and
save it as emacs lisp code.

for example, the attached (because the insert-kbd-macro command creates
emacs lisp code with control characters) defines a new command which, if
starting from a code block special edit mode, exits that block, saves
the file, tangles the whole buffer and re-enters the code block:
You can then bind this new command to a key of your choice.  Untested...

* new function
  Allows one to exit a special code block editing mode, save the file,
  tangle all code blocks and then re-enter the code block editing
  mode.

#+begin_src emacs-lisp
(fset 'esf/org-save-tangle-reedit-macro
   (lambda (&optional arg) 
     "Keyboard macro." 
     (interactive "p") 
     (kmacro-exec-ring-item (quote ("\x03'\x18\x13\x03\x16t\x03'" 0 "%d")) arg)))
#+end_src
