Tkinter - Can't bind arrow key events

Question

I am trying to bind the left and right arrow keys to an event in Tkinter, but when I run the program it appears the events are not triggering. Here is the code:

Answer 1

It might be that you don't intercept the right events. The arrows on the numeric keypad and the other ones have different symbolic names.

See http://infohost.nmt.edu/tcc/help/pubs/tkinter/web/key-names.html

the ones on the numeric keypad are named with a 'KP_' in front.

Hope it helps. Pardon a newbie if not pertinent :-)
