Shift + mousewheel gone?

[Punched-nagrand]

@Kaivax

The Key Bindings for selecting a specific action bar page (shift+1-6), paging forward (shift+mousewheel up), and paging backward (shift+mousewheel down) have been reset. These can be re-bound in the Action Bar section of the Key Bindings menu.

I think they were reset. Give this a try?
