The best online manual I know of for Tkinter is here: http://effbot.org/tkinterbook/ despite being 10 years old. But then I haven't looked for one for about that long, either. For tkinter key events are a bit odd, given that Tkinter tries to help you and considers special keys, punctuation and non-ascii printing characters as separate things should you want to bind to them. It's actually easier to write the code and say 'play with this' rather than to explain when you would need to use event.char and when event.keysym (Plus the code will tell you what Tkinter uses, I might remember wrong.) Save this in a file and run it. from Tkinter import * root = Tk() prompt = 'Press any key. Remember to keep your mouse in the cyan box. ' lab = Label(root, text=prompt, width=len(prompt), bg='cyan') lab.pack() def key(event): msg = 'event.char is %r and event.keysym is %r' % (event.char, event.keysym) lab.config(text=msg) root.bind_all('<Key>', key) root.mainloop() ---------- If you need to put unicode chars in your label, that's a different probem. If knowing when a control or alt-gr key is released is important to you, the code will have to be modified to detect this specially. Type some control chars at the cyan window and you will see what I mean. Happy Hacking, Laura -- https://mail.python.org/mailman/listinfo/python-list
