Locating item by UI code?

if i have the UI (? UUID ?) code to an item how do i go about locating it? is there a menu that will show these numbers or direct me to the place? some sort of gadget?

UUID means Universal Unique IDentifier.

There are several gadgets that can do this. I've never seen a whole and comprehensive list, so I hope a lot of people will post here to fill in the gaps.

One of them is CrystalShard Foo's Scan-Foo. You type in commands, it can do a particle point and locate it within X meters. Another is one that was given to me by FlipperPA Peregrine a long time ago, I forget the exact name but it was something general like "Object Scanner". I wish I could remember who made it too. I know the answer to that's going to make me blush.

a lovely lady sent me a script that did the trick in world so i'm all good, but it wasn't easy to track this answer down w/o posting in forums. there doesn't seem to be a lot on it unless you're a scripter yourself. so maybe this thread can still lend a hand to anyone else searching for the same answer in the future.

Cool, out of curiosity, could you please send that script to me? Who made it? Thanx!
