# It uses an Awk script, column -t, and rofi-dmenu to do so.
# Furthermore, rofi-dmenu expects the file ~/.config/rofi/keybinds.rasi to exist for theming.

# Awk script used for parsing `hyprctl binds`
# Basically:
# $1 contains submap; if empty replace with Default; also replaces shutdown mode. 
# $2 contains modmap; parsed and replaced with human-readable modifiers
# $3 contains key
# $4 contains description
