##### This is my (demuredemeanor) toggler script
# Source Code:  https://notabug.org/demure/scripts/src/master/toggler.sh
#
# This script is intended to be a scaleable invoker of various quick toggles I code.
# The inspiration was an AWK 'oneliner' that wasn't playing well with i3wm's bindsym+exec due to quotes/pipe.
