how do you propose to move the cursor within an entry or similar
widget?

the current code in GTK+ attempts to do "the best" thing, by using
arrows to navigate between focusable widgets except when the current
focus widget was felt to require internal navigation with arrow keys. 

you can override this in a key_release event handler, but its
moderately complicated, and will cause problems if any of the widgets
are entries and the user wants to navigate within them.
