textualuserinterface Based on the core (termina) vocabulary, I also provide a set of words for creating textual user interfaces. The model used here has the user provide three functions. One sets up a 'hints' area, one sets up key handlers, and one is the display. The `ti:application` word calls the hints & key handler setup, then runs a loop, calling the display word and then displaying the 'hints' below it. It will then read a key and process it.
