Mouse3 in the demo didn't work for me. I'm also keen to rebind mouse3, as I'm using a razer mouse which has notoriously damage-prone middle button.
I'm using esdf (turn, not strafe) at the moment, but it's slightly clumsy without the mouse3 function. I see no reason why mouse1 couldn't have the same function(similar to mmo controls) when you click on the terrain, as it wouldn't conflict with selecting units or clicking on the ui
