Use "text name { ... }". Look in the manual for it.
For a scrollbar , there are two options ... you could make it with buttons for 1 line down / up , or you could make a scrollbar wich will be harder (I cant think of a way right now how it could be done). There was a tutorial about scrollbars , but I dont remember who wrote it. Also , there is a 'text engine' in the AUM series , in the Morrowind section...
