the default key bindings for QLineEdit are hard-coded, but the actual 
key sequences used are platform-dependent (and the same goes for most 
(all?) other widgets which have them).

but what is your reason for wanting to change the default behaviour?

as a user, i would expect all the 'normal' shortcuts to work when typing 
in a line edit. if Ctrl+Z undid something in some other widget that i 
wasn't looking at, it could become very confusing. (IIRC this was how 
things used to work with qt3 - and good riddance to that!).
