I'm using Spacemacs, in term mode and on a mac. While I can adjust the standard font size I am often moving from/to a different monitor, and I want to be able to tweak the font size for the moment. Is there an easier way than changing the font size in my config file?

    You can use the inbuilt text-scale-adjust command or apply one of the solutions mentioned here: emacs.stackexchange.com/q/7583/115 – Kaushal Modi Aug 24 '16 at 16:32
  • @KaushalModi I'm a beginner to this sort of editor. It looks like I need to define a function to use text-scale-adjust, or is there some way to use it out of the box? – steel Aug 24 '16 at 16:37

    In emacs -Q (without loading custom configs like spacemacs), text-scale-adjust is bound to C-x C-=. After hitting that, you simply hit +,-,0 as you need. – Kaushal Modi Aug 24 '16 at 16:40

    Or you can find out if and what spacemacs binds that to by doing C-h f text-scale-adjust (not sure if spacemacs binds describe-function to C-h f or something else). – Kaushal Modi Aug 24 '16 at 16:41
  • @KaushalModi Thanks for the C-h f tip, that's great. The documentation there confirms what you're saying, but those bindings aren't working for me. – steel Aug 24 '16 at 16:42

On a mac it is CMD +/-.

To learn more about this, ctrl h f lets you learn about functions and their bindings. In this case text-scale-adjust, as described in other answers and blog posts. The docs say it is bound to C-+, but in this case, Cis actually the command key, not the control key.

  • I don't use Mac but I have seen the same for, I think, any software out there.. Microsoft stuff, Adobe stuff, etc: Ctrl (Win) <-> Cmd (Mac) – Kaushal Modi Aug 24 '16 at 16:55
  • @KaushalModi what's interesting is that looking up a method, C-h f, requires the control key. So it seems like maybe it means different things at different times on a mac? – steel Aug 24 '16 at 17:06

    That's definitely odd.. On unix-based systems and Windows at least, the C- means the exact same thing in C-h f and C-x C-=. To understand this better, I would first see in an emacs -Q session (without loading any config) if C- symbolizes.. is it consistently Ctrl, or consistently Cmd, or not consistent? – Kaushal Modi Aug 24 '16 at 17:09

    I hope a mac user weighs in to help you with this. – Kaushal Modi Aug 24 '16 at 17:10
