# LINUX VERSION
# Counts the total number of keystrokes
# Designed to compare battery performance wireless keyboards for Batteroo / Batteriser
# Just a quick implementation of pyxhook
# Most of this code is from the example file https://github.com/JeffHoogland/pyxhook
# Requires pyxhook module
# Visit GitHub https://github.com/JeffHoogland/pyxhook
# Just Download the raw pyxhook.py file and put it in the same folder as this script
# and run this script with python
# Press Esc at any time to Quit and show the count - remember Esc counts as a key!

    #print key_pressed
