f3 doesn't give me numbers, it just gives me string names like "minecraft:log1" or "minecraft:stone_bricks". and I tried f3 + h, but nothing changes, even if i reload the f3.
update: I was looking in the wrong place lmao. Found the 4000 numbered IDs by mousing over. still doesn't work with worldedit though, just says "couldnt figure out what ___ refers to", even with the mod prefix
