Fast Item Swap Add-on 1.20+

You no longer need to go into your inventory and equip weapons, slowly dragging one icon over another. Instead, you can use the mod Fast Item Swap, which changes the interaction with two types of items: the Totem of Undying and the Shield. Now, you can quickly equip them on your left hand without opening your inventory.

In addition, you can quickly move items from one hand to the other. However, you can only move the Totem and Shield from the right hand to the left, not vice versa. Check out the preview below to understand how the add-on works.
