+#### `/npc_talk_force_edit`	Toggles edit mode.
+		From now on (until you issue this command again), all NPC you
+		talk to will be in edit mode (provided you are allowed to
+		edit them). This is useful if something's wrong with your NPC
+		like i.e. you made it select a dialog automaticly and let
+		that dialog lead to d_end.
