please enable the "Professonal Mode" in "Settings" in our APP,
and more scenarios will be available in the config editor UI,
try one dedicated keymapping for looting or inventory in one of the TBD scenarios,
and activate this scenario(sub config) to use your new keymapping.
that might help:)
but please note that you are using the mouse and keyboard to simulate the controller, and you will have to think and behave as a controller user!
