I have Logitech MX310 and MX1000 mice. The "hardware" sensitivity is very different (quite evident) for each of them. When I use mx1000 after gaming with mx310, I'm getting tired of setting the right sens. value in the System Preferences. That's why I would like to know if there's a way of changing mouse sensitivity in-one-click. It's even better to set something like a preset with a key. Is there any solution for that? Thanks in advance, Matt.
