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.  This message is presented to
let the user know that he/she successfully copied the contents under flat
review to the clipboard.
