I'd like make a macro that handles virtually all interactions in a game (Talking, moving to the next page of a dialogue etc.). This way I can really reduce the need for players to use the mouse, however I'm not entirely sure of the best way to go about it.

I figure if I give all NPC's the verb Interact(), then one macro will work for all of them. As for things like dialogues, should I creat an Interact() verb that checks which page you are currently reading? Or is there a better way to go about this?

I believe NEStalgia does this with use of the Space key to interact.
