i don't know how to use the rubber at the moment, so for now, you can still use the pencil/pen - whatever. Numbers correspond to the selected colour, and 0 to change back to normal. Z to decrease brush size, X to increase thickness J to decrease colour, K to increase There are two different ways of operating the movement: - With the mouse - By holding space and cursors together. Hope you enjoy and if you have anything to help me with a rubber feature, then if you could let me know, that would be awesome!!
