looting everything

I know that if you shift-right click a corpse you will loot everything. Is there a way to switch it so that simple right click loots everything and shift-right click lets you choose? Loot everything is what I want the vast majority of the time . . .

Don't believe so. About the best you can do is turn off the Loot All confirmation, but it's advisable that you have this turned on when grouping and raiding in case there's a mishap.

I would love a loot all button... that would be great to help clear corpses fast...

It's an option somewhere in the settings.

When you right click on a corpse, there is a button at the bottom of the window to loot all.
