mentry::ipv6AddrMentry
  Commandmentry::ipv6AddrMentry – Create and manipulate
    mentry widgets for IPv6 addressesmentry::ipv6AddrMentry pathName ?options?
pathName
    for displaying and editing IPv6 addresses in the standard hexadecimal
    notation (where the eight groups of one to four hexadecimal digits are
    separated from each other by o colon).  The supported
    options are the same as in the case of the
    mentry::mentry
    command.type attribute of
    the widget to the value "IPv6Addr" and returns the name of the
    newly created widget.mentry::ipv6AddrMentry command defines five new
    keyboard bindings for the entry components of the mentry widget it
    creates:  The Up key increments the entry's value by 1 if
    the latter is less than 65535.  Similarly, the Down key
    decrements the entry's value by 1 if the latter is greater than 0. 
    The Prior key increments the entry's value by at most 10 if
    the latter is less than 65535.  Similarly, the Next key
    decrements the entry's value by at most 10 if the latter is greater than
    0.  If the entry is empty then all of these keys insert the value
    0 into the entry.  Finally, Control-v
    (Command-v on the Mac) pastes the current contents of the
    clipboad into the mentry, provided that it is a valid IPv6 address.Up and
    Down keys can also be triggered by rolling the mouse
    wheel.  In addition, on Mac OS Classic and Mac OS X/11+ Aqua, the
    actions performed by the Prior and Next keys are
    also triggered by the <Option-MouseWheel>
    event.  The same holds true on all windowing systems if the Tk version
    is 8.7a4 or later, where the Option modifier is bound
    to the Option key on Mac OS X/11+ and to the Alt
    key on Windows and X11.mentry::putIPv6Addr Commandmentry::putIPv6Addr – Output an IPv6 address to a

    zeros).  The command generates an error if the address is
