Emacs: Uncolor Region/Buffer
Normally, you can Alt+x font-lock-mode
to turn off syntax coloring.
But if you copied some text from another buffer into a new buffer, turning off font-lock-mode
won't remove existing coloring.
Here's a command that removes syntax coloring.
(defun xah-unfontify-region-or-buffer () "Unfontify text selection or buffer. URL `http://xahlee.info/emacs/emacs/elisp_uncolor_region.html' Version 2017-05-31 2021-10-04" (interactive) (if (region-active-p) (font-lock-unfontify-region (region-beginning) (region-end)) (font-lock-unfontify-buffer)))
