"Squeak by Example" section 6.2 , in the section on "Refactoring" discusses the "R" button that should appear on the far right end of the button bar. I'm using squeak-dev which uses OmniBrowser by default, but that button isn't there. What do I need to do to add it? The footnote at the bottom of that page indicates that it should be there by default.
