iD: moving map using arrow keys

Moving the map with the arrow keys in iD editor is in very small steps.
I would like to have the same behaviour as in Potlatch2, where one touch of an arrow key moves the map half the screen width or hight.
Dragging the map with left mouse button pressed is very uncomfortable for me.

For such a feature request I recommend to open an issue in github at https://github.com/openstreetmap/iD/issues
