FindMe allows you to search for items in nearby inventories by pressing a key. For that you simply need to hover over an item

I use this myself and it works great. Keep in mind it is a server-side mod as well now.

It currently has a bug with AE2 interface terminal, where it cant render the encoded recipe's output
Buuz135/FindMe#20

its fixed in AppliedEnergistics/Applied-Energistics-2#6132 , so it should be fine now
