;;; kbd.el --- Elisp keybinding -*- lexical-binding: t -*-
;; Author: William Carroll <wpcarro@gmail.com>

;;; Commentary:
;; In order to stay organized, I'm attempting to dedicate KBD prefixes to
;; specific functions.  I'm hoping I can be more deliberate with my keybinding
;; choices this way.
;;
;; Terminology:
;; For a more thorough overview of the terminology refer to `keybindings.md'
;; file.  Here's a brief overview:
;; - workspace: Anything concerning EXWM workspaces.
;; - x11: Anything concerning X11 applications.

;;; Code:
