What are the two buttons on the left side of Logitech M510 wireless mouse for?

[zzzhhh]

As title. They doesn't do anything when I press them. Thanks.

You'd need specific drivers to allow presentation of all those buttons to the OS, and then to define each button's function within a game...

It's not as if WIndows has normal 12 button mouse's functions laid out by default..

Normally they are back and forward and will work inside folders and browser windows, get drivers from their website if they don't do anything
