[Garrett Regier <gregier src gnome org>]

commit 568bb9b4d7a4dfaf909358c659660c96da58859e

    Bug 697433 - Allow directly typing a path in file browser
    
    The path can be either absolute, uri, or relative. The entry is initially
    hidden and is only displayed when ~, /, \ or Ctrl+L are pressed and
    will be hidden if Escape is pressed.
