Right Click - Ability to use the right mouse button. There are many ways this could be done without messing with verbs. Let each atom have a var called right_click or something. If the developer sets the atom's right_click var to 1, then right click will call the atom's RightClick() proc, and if it's set to 0, it will call the verb list and do any other thing it does in the current version.
I'd suggest that BYOND just checks whether atom.RightClick() is defined for an object, instead of checking some sort of atom.right_click variable.
No you don't. There's only one turf in any given spot. One is an underlay of the other.
And you're misusing the word "area" here to mean "turf". An area is a collection of turfs, not a specific spot on the map; that specific spot is a turf.
With turfs the effect is purely graphical, and in the map editor rather misleading.
