EVT_KEY_DOWN has this autorepeat behaviour, done.

It does now ;-)

Haven't got an easy solution to this one. Problem is, we are setting the 
selected line in the wxListBox "manually" in response to keypresses. If you 
transfer focus to the list by clicking, then it shows the proper behaviour 
(as it is using its own handlers to respond to the keypresses).

The best solution would be to shunt the key events to the listbox using 
wxEvtHandler.ProcessEvent (), but this doesn't work. Nor does manually 
setting the focus using wxWindow.SetFocus (). There is no documented
way to programmatically control the scrollin go the list box. wxListCtrl does 
have this API, but only on windows.
