49Ttk is the new Tk themed widget set. \
50One of the widgets it includes is the notebook widget, \
51which provides a set of tabs that allow the selection of a group of panels, \
52each with distinct content. \
53They are a feature of many modern user interfaces. \
54Not only can the tabs be selected with the mouse, \
55but they can also be switched between using Ctrl+Tab \
56when the notebook page heading itself is selected. \
57Note that the second tab is disabled, and cannot be selected.
