When enabled you must use a modifier key while right clicking to sell items to a vendor to help prevent accidental item sales.
This was mainly written to be used with Khaos, but was developed to work without it by providing slash commands when Khaos is not present:
/modifier2sell help -- EN
/modifier2sell aide -- FR
/modifier2sell hilfe -- DE
If bag modification addons wish to be compatible with M2S they can use
Modifier2Sell_BagSlotButton_OnClick(button, ignoreShift, bag, slot)
AllInOneInventory already supports M2S. }}}
