Correct. Shortcuts are automating biscuits logic. Not only Greenacres type but all the actions on checking whether grenade is inventory, what type, primed already, and on and on. Essentially just an action script. I programed it for vanilla item set.
Can be redone for ogre sets but not customizable.
Meridian is right that it may be not good to force all player to this automation. However, it is not forced. Player ca use it or not.
