[Eli Cochran]

As for the keystrokes, I think that it makes sense if it is a tab and  
arrowkey combination. Tab to the element and then move the element  
using the directional keys. Similar to reordering an item in a list. I  
always like arrows for movement, it seems natural.

I would also allow for larger jumps than single step increments. Most  
layout and drawing applications use the arrow key alone to move by 1  
(whatever 1 means in the context) and then shift-arrow to mean move by  
1x (where x is usually 10 or the next grid step or, again, whatever  
makes sense in the context).
