What makes this item so special that it gets to go to that part of my screen? How do I use it? Are there other items like this?

Those are part of a new item class called "Trinkets". They're like a mixture of useable items and passive items; the effect is always present, but you can only have one at a time. If you find another trinket and pick it up, you'll drop the one you have right now.
