Bind key to increase / decrease font size in emacs

elisp, emacs, font-size

Solution

I think you want `C-x C-+` or `C-x C--`.

Problem

In my terminal (I have terminator) I can use the key combinations Ctrl + and Ctrl - to increase / decrease the font size. In emacs I can do the following to set the font-height: ``` (set-face-attribute 'default nil :height 70) ``` But I do not know how to increase / decrease it. How could I easily add this to my emacs configuration?
