[Qt-creator] Keyboard Bindings under OS X

[Gabriele Genta]

Hi,
I would like to know if there's a way to define keyboard bindings for
the following actions: go to end of line, go to beginning of line,
select to end of line, select to beginning of line. What I want to
achieve is to make the Home and End keys under mac os x work exactly
as they do under linux or windows.
Thanks a lot,

 Gabriele Genta
