After receiving help the system saves the history of page switching.
To return to a specific page, use the switching button "Back" and "Forward", used to switch between the next or previous page that was already viewed.
For fast navigation to the required page use the button to the right of the specified buttons. Clicking the button opens the list of page names.
If there are more than 9 transitions (transitions in the direction corresponding to the switching button), the list displays only the nearest nine pages and at the end of the list there is a row containing the text "History". A complete list of visited pages is displayed at selecting this row of the list.
To select the required page, specify the list row with the page name and press "OK".
