Quick thing.

I've found the key combo to pull items from something without opening them (IE Metal plates from a smelter), but how can I load items. (IE: Coal to a Train, or robotic arm) ?

Holding the items you want to put into something, Ctrl-left-Click if you want to fill a full stack, Ctrl-Right-Click if you want to add half a stack.

Is there anyway to do it without holding an item?

Also, many thanks for the answer Koub.

It's the only way the game can know what item you want to insert in the device you're interacting with.

Assumed as much, but just wanted to check.

Thanks for the help Koub.
