Disable Emacs text scaling

Question

Is it possible to disable text Scaling in Emacs? Whenever I reverse the undo direction (Cx C--), the text size decreases. I am using Emacs 24 with Prelude on Ubuntu 12.04

Answer 1

In addition to @xfq's answer, you can turn off scaling by unsetting the key in your init file, or your .emacs file (available at ~/.emacs).

(global-unset-key (kbd "C-x C--"))

( remember that you can reload the file without restarting emacs using Mx load-file .emacs when you're done editing )

You can read more on these commands by typing Ch f text-scale-adjust RET . text-scale-adjust is bound to Cx C-0 , and resets any scaling performed by Cx C-- or Cx C-+ , as explained in that page.

Answer 2

Try Cx C-0 0 . It can reset the default face height to the global default.
