I'm probably one of the few people these days that uses a trackball mouse still. The thing is ancient, but I love it and wouldn't trade it any day. I however have a major issue that's preventing me from using a simple yet important feature of the game.

I can't zoom in / zoom out of the map because my mouse does not have a scroll wheel. Please if at all possible make it so that we can map a new shortcut key for the map zoom function. I'd really like to be able to use my map!

Thanks.
