1. Put any items in crafting slots of the inventory
2. Open the guide book using "Ctrl" (hover over an item to lookup in guide book)
3. Close the book (Esc)

The items are kept in the crafting slots, they dont affect the weight of the player (you can store like 4 large vessels or anything else).
They are stored in these slots until you open the inventory again.
Does not work if you open a book with a button on the side of the inventory.
