we should be able to set priority for keyboard keys
i.e., when i'm busy mining, normally i just press enter twice to mine if i'm in front of it
when a person/vendor/animal get close enough to me i now have to press enter, arrow (up to 2 times) then enter 2 more times.
if the rocks had priorities, i would just have to press enter 3 times and "if" i want to do another action, then i can use the arrow keys.
