Start the UITK gallery, and resize the window to have a single column.
Now, with TAB you can navigate between the actions in the header, and the ListItems in the listview that list the different Pages with components. But it is not possible to use the arrow keys to select a ListItem, and then press ENTER/SPACE to open that page, because pressing the arrow (up/down) key automatically triggers the ListItem (onClicked?) and opens the Page. So only the first Page (ActionBar) can be opened using keyboard navigation when you have only one column.
