Based on other replies it looks as if the OP found a way to intercept 
the event with suitable binding.

But I can answer the "why": on Mac OS X in a one-line text box up-arrow 
should move the cursor to the beginning and down-arrow to the end. 
That's standard behavior.

In any case I can't imagine ever wanting to see special chars get added 
when arrow keys are pressed. The default behavior of the Entry widget is 
unfortunate.
