In the default view when "KDE Adress Boo" is started, the content of the Action flap reads: Address BookAddress Book Properties... KAddressBookAdd Address Book Folder... where it seems that "Address Book" and "KAddressBook" are labels and the rest of the strings buttons. Touching the upper string results in nothing but short visual feedback, touching the lower opens an text input view "New Address Book Folder - KAddressBook Mobile".
