Honestly I don't think he's actually doing anything nefarious. I think he's creating some kind of global keyboard shortcut or macro utility.
But I'll gladly ignore him. I have seriously tried to help in the past. But he's the most anger-provoking poster I've had the misfortune of encountering.
Are you now trying to read passwords by hacking the OS kernel? Should you manage to write software that can read the keyboard while entering passwords (which I doubt) installing it anywhere will most likely make you liable to criminal prosecution.
Independent of whether it's something nefarious or not I meant it as a don't bother too. Since I've tried helping him too and he just ignores what you tell him.
