# keyboard automute for linux
# makes you less of an ass while using your MECHANICAL KEYBOARD in zoom/teams/whatever meetings
#
# usage:
# 1. build the kernel module in keycounts, then insmod keycounts.ko
# 2. run this script as root
# Note, you may need to modify the mute() and unmute() functions to actually mute and unmute
# on your system
# YMMV
# if you like this, buy me a beer or support your local charity
