well, arma has a scrollwheel for commands on the mmb, so hopefully you've got that figured out. Maybe both will work. I dunno, I've always used wasd for movement. To each their own, if they can get everything to work.
you have to manually delete the old keybinding as well, arma is one of those annoying games where it doesnt do it automatically Any conflicting ones are highlighed red if i remember rightly, which makes them easier to find
