+;;  - right: Vim-like arrows on HJKL, home/end page up/down, mouse scroll
+;;  - left: Tab/Shift-Tab, prev/next
+;;  - top: Super-num (i3/sway) or Alt-num (browser), zoom in/out
+
+;; The `lrld` action stands for "live reload". This will re-parse everything
+;; except for linux-dev, i.e. you cannot live reload and switch keyboard devices.
