Floating Toolbar: -oxy-floating-toolbar Property
Used to display a configured floating toolbar in Author mode.
-oxy-floating-toolbar property is used to configure and display a
      floating toolbar in Author mode. It accepts a space-separated list of
      the following functions:- oxy_button
- oxy_buttonGroup

"|" text value can be used to add a separator between elements of the
      toolbar.  It must be used in conjunction with the -oxy-selected and
        -oxy-selection-inside pseudo-classes. The -oxy-selected
      pseudo-class is automatically set on an element that is fully selected and the
        -oxy-selection-inside pseudo-class is automatically set on an element that
      has a selection inside.

    -oxy-floating-toolbar: 
        oxy_button(actionID, 'bold')
        oxy_button(actionID, 'italic')
        oxy_button(actionID, 'underline')
}This results in a floating toolbar that contains bold, italic, and underline actions presented in Author mode every time text inside a paragraph element is selected.

            edit, '@platform', 
            editable, false, 
            values, 'windows, mac, linux', 
            labels, 'Windows, MacOS, Linux'
            )
}This results in a floating toolbar that contains a Platform:
      label and a drop-down menu used to change the value of the @platform profiling
      attribute. This is presented in Author mode every time a paragraph
      element is fully selected.
