Help Pane is represented by the HelpPane class. It is located on the top-right side above the Ribbon Tabs content. The Help Pane is shown regardless of what Ribbon Tab is currently selected.
You can use regular, radio and toggle buttons within a Help Pane. The Icon property specifies the icon displayed by the button. The Content property specifies the button tooltip. There are two ways of specifying which actions a button item will perform - using the Click or Tapped event or attaching an ICommand object to a button via the Command property.
