# Send chat messages to Heroes of the Storm via hotkeys
#
# This script features binding chat messages to the keys F5, F6, F7, F8 and F9 by default.
# Key F5 - F8 are subject to single chat messages where key F9 will be subject to a switching
# toggle. That means you can specify a dynamic amount of chat messages that will be iterated on
# and once the end is reached, it will be starting over from the beginning again.

# You can edit the chat messages via the GUI (except switching toggles). The script does also check
# if the current foreground window is the window of the game in order to prevent that the chat messages 
# are inserted elsewhere.
#
# Chat messages are stored in the text file defined via the constant CONFIG_NAME. If it does not exist
# then the script will create a sample file that can be edited afterwards.
