Describe the feature
There should be an easier way to open latex-preview-pane-mode when in LaTeX mode than using M-x then searching for it.

System information

((system
  (type . gnu/linux)
  (config . "x86_64-pc-linux-gnu")
  (shell . "/usr/bin/zsh")
  (uname . "Linux 5.4.0-48-generic #52-Ubuntu SMP Thu Sep 10 10:58:49 UTC 2020 x86_64")

Such a test would be very useful on CI to prevent from silly mistakes like the one in #1279 creeping in. Basically we need to:

• clone Prelude
• start Emacs

Describe the solution you'd like

It should be possible to provide a custom formatting configuration for cider-nrepl/cljfmt.
The cljfmt configuration format is described here:

https://github.com/weavejester/cljfmt#configuration

The desired solution should have a defcustom variable where the configuration can be provided.

Describe alternatives you've considered

A workaround

These boolean variables do not seem to have an effect when enabled through an entry in custom-set-variables.

zenburn-use-variable-pitch
zenburn-scale-org-headlines
zenburn-scale-outline-headlines

Should these be removed from the customize interface and a comment be added to the README telling users to set this before loading the theme?

Expected behavior

Proper syntax highlighting

Actual behavior

Steps to reproduce the problem

Write a form containing a word starting with def anywhere, e.g. (defface 'angry-face)

I get that the intent was to highlight defresource etc the same way as defn but this reall
