You are looking for the G-series Profiler, probably in your Logitech Program. Try this Logitech G19 page
Thanks, but the problem was that i couldn't find the link to the key profiler. But i already solved it. In the logitech map located in my program files, there is a file called :
(map g-series) "LGDCORE". Wich is the key profiler. I made a link on my desktop and everything is solved.
But thanks for the help anyway, i appreciate it
