The Navbar can simply be closed be left clicking the little cross in the top right of the Navbar, and restored by either typing in "navbar" at the command line followed by typing in the option "on", or left clicking on the dash in the top left hand corner of the drawing area. From the displayed menu the visibility of the view cube may also be controlled.
