Arrow Cycling: If you have multiple types of arrows in your inventory, eg: Regular, Beast, Explosive, Comet, Poison, Skeleton, then you can cycle between all of the arrows by left clicking with a bow. If your bow has infinity then it will only apply to Regular arrows, not custom arrows.
Exp Trading: When right-clicking an enchantment table with a glass bottle, or an empty bucket, you get an item that saves the exp. You can save the items in a chest to prevent exp loss when dying, and sell the items on the market for cash.
