Read Only

I just had one of those “Well Duh! Of course” moments. It came to me with this Emacs Command of the Day tweet:

I always think of Ctrl+x Ctrl+q as turning off read-only-mode in a grep or Dired buffer. See Mike Zamansky’s video on Dired for an example of the latter. But, of course, what it really does is toggle read-only-mode so if you want to put a buffer in view-mode to prevent inadvertent changes you can just use Ctrl+x Ctrl+q to turn it on.
