When crafting something using the recipe book and not having enough materials, you can shift click another item into the crafting recipe while still having the recipe book suggestion open (i.e shift clicking a block of gold into an incomplete golden sword recipe). This causes both item names and properties etc. displaying at once in max windowed. In a lesser resolution, item names display seperately but still at the same time. Sometimes, both item textures display, but not both names. Images below.
