+ Disable use of keyboard keys for scrolling.

+ By default cursor movement keys (including Home, End, Page Up and Down)
+ are used to scroll the window appropriately. If the derived class uses
+ these keys for something else, e.g. changing the currently selected
+ item, this function can be used to disable this behaviour as it's not
+ only not necessary then but can actually be actively harmful if another
+ object forwards a keyboard event corresponding to one of the above keys
+ to us using ProcessWindowEvent() because the event will always be
+ processed which can be undesirable.
