What you see here:
I can't do that. FIrst of all I have to hold down ctrl to give move orders, which seems weird but I'm not sure because I just bought the game.
But when I do hold down ctrl and right click, all I can give is give a simple move order to a specific location. If I click and drag, after I let up on the right mouse button all it does is order the unit to the point where I clicked to begin the drag.
