Logitech G-Series Keyboard script

--[[
This script is made by GeekGarage aka. xibit1987
Created for G19, but will work on other G-Series hardware

Guide on how to use:
{["key"]=12, ["state"]=false, ["type"]="t", ["keys"]={"rctrl", "lshift", "s"}, ["mouse"]=1, ["lcdText"]={"Text Here", "and you", "can use up to 8 lines on G19", "and 3 lines on others"}}

"key" is the G-Key number, for now it's not in use and is only there to keep an overview of the array so it's easy to see what key you are editing
"state" DO NOT TOUCH! Used to check state in toggle type mode
"type" is Toggle type key [t] or Hold/keep pressed down type of key [h]
"keys" are what keys to emulate pressed, always add modifiers first like "lshift", "rshift", "lctrl", since it will be pressed in the order they are added (Look at example above). Default if not in use is    ["keys"]={nil}
"mouse" is what mouse button to press (can only handle a single button. Default if not in use   ["mouse"]=nil
"lcdText" is the text you want to display. each section ["Text Here"] is a new line. The display can show up to 9 lines, but the last line is used to show if key is toggled or pressed down

Remember if you add a line ONLY the last one is without "," at the end. Same if you delete some of the keys, remember to remove "," at the last one

this is a default line for a key not in use:
{["key"]=1, ["state"]=false, ["type"]="t", ["keys"]={nil}, ["mouse"]=nil, ["lcdText"]={nil}}
