I would like to temporarily not be able to see what I am writing (counter-intuitive, I know, but sometimes it's helpful to not be able to immediately criticize what you are writing in order to actually get some writing done).
One solution would be to turn off my display, but that is rather complicated in some situations (most laptops nowadays --including mine-- don't dim to 0% and other solutions are OS dependent). As I use emacs for pretty much any type of writing, I would prefer an emacs solution. As I am lisp-illiterate (still, sigh), I could use some help.
I presume that making text invisible can be done by setting the facecolor to the background color; however, I don't know how to do that outside the
Edit>Text properties>Display Faces menu. Furthermore, I would also like to be able to toggle the visibility of the text and I have no idea how to restore the previous color.
Any pointers are appreciated.
