+** Keybinding Panel (which-key)
+
+[[https://github.com/justbur/emacs-which-key][which-key]] is great for getting an overview of what keybindings are available
+based on the prefix keys you entered.  Learned about this one from Spacemacs.

+#+begin_src emacs-lisp

+** Simplify leader bindings (general.el)
+
+[[https://github.com/noctuid/general.el][general.el]] is a fantastic library for defining prefixed keybindings, especially
+in conjunction with Evil modes.
+
+#+begin_src emacs-lisp
+
+  (setup (:pkg general)
+    (general-evil-setup t)
+
+    (general-create-definer mr/leader-key
+      :keymaps '(normal insert visual emacs)
+      :prefix "SPC"
+      :global-prefix "C-SPC")
+
+    (general-create-definer mr/ctrl-c-keys
+      :prefix "C-c"))
