I know a lot of you are not programers and dont want to mess with code. I have an alternate solution for you. Its called HIDMacros. its bacically the pre-project of luamacros. same guy made it but didnt want to bother with the gui. Again like Taran said LuaMacros is in beta so HIDMacros is like the alpha version. The good part is that it has a gui so the learning curve is much less steep. In my time using HIDMacros i haven't encountered any difficulties with it. Please note that it is deprecated so the amount of help you will get is almost none.
