A:AnswerThe top part is a touchpad. It can recognize scrolling with one or two fingers, and can recognize the different amount of fingers on the touchpad as well.
A:AnswerThe batteries can be rechargeable or not, but there is no way to recharge rechargeable batteries through the mouse. It takes two AAA batteries, and, with normal use, they last about six months.
A:AnswerI don’t believe it can pair to multiple devices but if you’re using two monitors, they should both be connected to the same computer. The mouse also connects to the computer, not the monitor, and you will be able to use the mouse on both screens.
A:AnswerYes you can right click. It does have a quirk where you have to lift your index finger to right click but apparently I had always done that as a habit anyways since it never bothered me when I got this mouse.
