You are most welcome. Sorry if I mangled the indent when pasting it into my mail. http://infohost.nmt.edu/tcc/help/pubs/tkinter/web/index.html is useful. Especially http://infohost.nmt.edu/tcc/help/pubs/tkinter/web/key-names.html So is http://effbot.org/tkinterbook/ Write back if you run into trouble. The simple code I sent is just about binding every key press to something that announces what you pressed. You will have to bind particular keys, or sequence of keys to what you want to do. Write a small example to make sure that tkinter can talk to your Kade device ok, because if it cannot we will have to look harder at the problem.
