The game was designed with mouse in mind, so would take a lot of rewriting to make it possible to configure the click buttons to keyboard buttons, and I don't think it is worth it, as most people have a mouse even for laptop. I have considered copy paste, but I don't think I am good enough at programming to make it work. The drones usually have one position from which they pick up and one position to which they deliver, and a range of 96px I think, so if a position is more than 96px (radius) away from the base, it won't use that position. It is possible to put fuel in the drills, both by hand (right click) and with funnels/drones. It could be if the hitbox of the ore vein is in the way, that the funnel won't be able to be placed right up against the drill, in which case it won't funnel into it. You can fix this by placing the drill centered on the ore vein, or off to one side where the funnels are gonna be.
