That's right -- to enter, just comment on this post, and tell us what you'd bind the "5" button to (that's the one right in the middle, as you can see above) before this Saturday night at 11:59pm. You can enter only once, and one winner will be picked in a random drawing to win both a Razer Naga mouse (MSRP $80), as well as a Razer Megasoma mouse mat to push it around on (MSRP $50). You must be 18 or older to win, as well as a resident of the United States or Canada (excluding Quebec). Click here for the complete official rules.
Good luck to everyone who enters!
