Let me try to explain the odd logic of the numeric, alpha and ip
input types.

With only 4 keys, the Enter key is used to step to the next digit/character.
Only when the last digit/character of the input is reached, the Enter key
leaves the menu.

With 6 keys this kind of logic is not necessary, because here we have the
Left and the Right key to move left resp. right.

Hope this helps
Peter
