Hot Key suggestion

I think It is pretty cool how you are able to push some buttons on the keyboard and it will do certain things. For instance how you can press "c" and it will take you to your capital. My suggestion is that the arrow keys will either move your map around or zoom in and out. I do not know how other players feel about it but to me I think it would be a whole lot speedier to move around the map and organize troops. Organizing troop movement is a pretty tedious task late game, especially in 50 or even 100 player maps with this feature you could quickly move the map without having to move your mouse. While overall it may not seem like a big issue but I think it would resolve a bit of frustration and increase enjoyment in the game.

Edit: perhaps assign the "a""s"d""w" keys as well or instead.
