I've been watching a Last of Us let's play after I play each section and I've noticed that when he comes upon a number of items in one place, they all get picked up at once. Is there a way to pick up a bunch of stuff at once, or is he just hammering the triangle button?
You can pick up multiple items at once by holding triangle.
Note: I usually still prefer to pick them up one at a time so I can see exactly what I'm getting. But if you the ability to tell without the little symbols this can save you some time.
