Spacemacs (Emacs) Fonts And Faces Notes

** View Details Of The Current Letter

The way to see details of the character under the current point is to use ` what - cursor - position ` with the universtal prefix argument.

On Spacemacs the command is : 

SPC
  u
  C-x
  =

You can also use [TODO: Code shorthand span ] which is the default ` M - x ` for me, but also mapped to ` SPC SPC ` . Using it, you can add the universal argument towards the end of the command like : 

M-x
  what-cursor-position
  C-u
  RET

And you don't have to type all of ` what - cursor - position ` just enough so that it's the first highlight in the helm list. Just make sure to hit [TODO: Code shorthand span ] before hitting RET (return)

In default Emacs, the universal argument is set with [TODO: Code shorthand span ] instead of ` SPC u ` , but Spacemacs rebinds it so it can use [TODO: Code shorthand span ] as scroll up like Vim does.

So, if you're using an Emacs setup that doesn't rebind the key, the command is : 

C-u C-x =

** Viewing Font Faces

I'm setup to use helm. To see all the font faces and what they look like use : 

M-x spacemacs/helm-faces

When the list comes up, you can select a face and hit RET to view the settings for it and then select the [TODO: Code shorthand span ] link to change it.

** Changing Font Faces

For some reason in my setup I can't remove a property (e.g. Foreground or Background color) from a face. It won't save. I have to replace it to get it to stay.
