Ttk is the new Tk themed widget set. \
One of the widgets it includes is the notebook widget, \
which provides a set of tabs that allow the selection of a group of panels, \
each with distinct content. \
They are a feature of many modern user interfaces. \
Not only can the tabs be selected with the mouse, \
but they can also be switched between using Ctrl+Tab \
when the notebook page heading itself is selected. \
Note that the second tab is disabled, and cannot be selected.
