Selecting a tile and pressing the shortcut key to nudge its pixel offset (pressing + to nudge it up in the z value, for instance) doesn't work without first selecting the nudge command from the context menu by right-clicking the selected tile. Also, only matching tiles are affected, including any pixel offsets.
While working with the new isometric map editor, I've found it very tedious to try and raise or lower the elevation of the turfs using the nudge commands. Any dissimilarity between two tiles will result in only the active tile being nudged.
I would prefer it if all selected atoms respond to the nudge commands, irregardless of type, icon_state, pixel offsets or other differences. In addition, we should be able to use the nudge shortcut keys, like +, to instantly alter all selected atoms without having to first use the command in the context menu.
