1) When I put up a List widget The arrow keys don't work. I can only
use the mouse to choose from the list. The docs don't mention anything
about this. How is this done?
2) I want to display a List box and then while my code is running
update it with text as needed. After the root.mainloop() how do you
start your main program to run and update the list when necessary? Any
sample code would be qappreciated.
