No longer able to bind keys to numpad enter

[Hyohakusha]

Being left handed, this really sucks as I've already got the rest of the numpad bound. It used to be my melee channeling button, and while changing it to a mouse button works for say Excal's 4, it makes dual wielding a glaive and pistol impossible. I don't see why it was changed; if someone was going to use the numpad normally, they wouldn't bind anything to it in the first place.
