selecting dig then ctrl-left clicking on a tile will dig all of the corners to the same height as the lowest corner, then when dumping dirt if you hold ctrl it will only dump enough dirt to bring it to the same level as the highest corner. And ultimately holding shift and dumping dirt on a tile intersection will add 1 dirt there, I think. Also keep in mind that when digging normally, without ctrl, if you click a tile it will lower the north-west corner of that tile.
Exactly 6.022 x 10^23 worth of Lach molecules.
