There is already the E key to use default action, what about 3 default action you can set on, lets say Q E R for example
E is your first one, let say, it open Warehouse inventory
Q is your second one set to .. let say .. Open Warehouse Door
R is set to inspect
I find this a good idea because you wont to clic and select option as much because you preselected 3 of the action you use the most on that item.
Huge game changer.
