I don\'t exactly understand you ?(
But anyway:
Whenever you begin talk with an NPC, a chat-dialog would show up. It would consist of three parts: a chat-history, the predefined list, plus a single line editor at the bottom, like the one that is present in the game now. The list would contain
COMMON sentences, that you would probably do with that NPC (ask for beer from a bartender, ask for weapons, repair from a blacksmith, etc.). Whenever you click one of these, it would have the EXACT same effect, as if you had typed that in and pressed ENTER. It just saves you the time, as writing COMMON things a thousand times can become really boring after some time - not speaking of typos...
Here is some ASCII-ART for a chat-dialog:
This d.a.m.n board removes spaces

So, what do you say?

P.S: Is it intended, that the board replaces \"d.a.m.n\" with \"dang\"?
