;;; keybindings.el --- Centralizing my keybindings -*- lexical-binding: t -*-
;; Author: William Carroll <wpcarro@gmail.com>
;; Version: 0.0.1
;; Package-Requires: ((emacs "25.1"))
;;; Commentary:
;; Attempting to centralize my keybindings to simplify my configuration.
;;
;; I have some expectations about my keybindings. Here are some of those
;; defined:
;; - In insert mode:
;; - C-a: beginning-of-line
;; - C-e: end-of-line
;; - C-b: backwards-char
;; - C-f: forwards-char
