I have a logitech M557 bluetooth mouse, and it has a start button (key133) on it. I would like the button to be re-mapped to mouse key2, which is basically clicking on the scroll wheel. I've tried to re-map the mouse's key9, which is the button mapped to keyboard's key113, to key2, but that only made the situation even worse, because it's still subsequently mapped to key133, while having the newly mapped key2 function. Please help! Thank you!!
