Translators: the 'flat review' feature of Orca allows the blind user to
explore the text in a window in a 2D fashion.  That is, Orca treats all
the text from all objects in a window (e.g., buttons, labels, etc.) as a
sequence of words in a sequence of lines.  The flat review feature allows
the user to explore this text by the {previous,next} {line,word,character}.
Flat review is modal, and the user can be exploring the window without
changing which object in the window which has focus. The feature used here
will return the flat review to the object with focus.
