FYI, this checkbox seems to not function. Enabling it does not allow AOE looting.
Binding a key to AOE looting (I bound mine to “I” for example as a test) does work, so it appears to be just that one option that fails.
From the release notes:
but will only trigger the AoE Loot functionality while none of the forms of the interact dialog are visible.
In short, the interact dialog (literally any form of it “Greet”, “Talk”, etc) cannot be on screen. We have it this way because of internal feedback. The functionality stems from an issue people were having while, for example, harvesting. It was really awkward to harvest something and have your inventory fill up by other junk.
I do realize that it isn’t really communicated well in-game, mostly because of it being a last minute change (we also increased the range!). That being said, I’ll probably revisit this feature in the near future and see about giving it that extra spit shine polish

Just keep in mind there is a seperate keybinding for AoE Loot that will always work, regardless of Interact prompts.
The extra keybinding doesn’t really work for me as I have my middle mouse button set to the Interact binding. Which means that I really like it if “Search” became “AoE Search” when the AoE Looting checkbox was enabled!
I’m going to be talking with Design about this issue this week. I like the idea of changing the text to “AoE Search/Loot” when you use that option and having AoE Loot trigger when that prompt is up (but only when the search version of that dialog is up).
