＃+ BEGIN_SRCと＃+ END_SRCを非表示にする、ソースコード内にソースコードのみを保持する方法はありますか？表面的なものですが、短いコードスニペットをたくさん処理しなければならない場合は、状況が明確になります。例えば：
(defun org-xor (a b)
"Exclusive or."
(if a (not b) b))
の代わりに ：
#+BEGIN_SRC emacs-lisp
(defun org-xor (a b)
"Exclusive or."
(if a (not b) b))
#+END_SRC
回答:
で始まるすべての行の顔#+はと呼ばれorg-meta-lineます。
この顔をカスタマイズして、目立たなくすることができます。
(set-face-attribute 'org-meta-line nil :height 0.8 :slant 'normal)ます。それはかなり役に立ちます。
org-meta-line gnu.org/software/emacs/manual/html_node/elisp/…に
私は次のコードを使用しています。それは完璧ではありません。多分それはminor-modeいつか適切になるでしょう。（ソース）。
