Where is the edge loop hotkey set in the keymap section of 2.8? Alt+LMB does nothing, and I'm trying to determine if this is a bug and the nature of the issue so I can report it. In looking at the keymap settings, I can find "Edge Ring Select" twice, but not "Edge Loop" which should be Alt+LMB.

Can someone tell me where specifically I can find this hotkey to make sure it's present and set? (ie what is the full path to it in the Keymap tree, or what search term will show it)?

Is there a way to add it back manually?

I've tested this on the Feb and April 14th builds of 2.8 and the same issue is present. I've also reset to factory defaults.
The &#9095; Alt-Select can be found under "Loop Select" and should exist in the default settings.

Edge loop select refers to edges that are connected end to end, while edge ring is a ring of parallel edges between two edge loops.
