[Pharo-project] Indent code

When I select a few lines of text in Pharo 2.0 code editor and hit TAB it is not indented as in other IDE's. Instead it is deleted similar to when one hits space key. Usually TAB in IDE code editors is used to indent a selected block of text and SHIFT+TAB is used for the reverse (outdent). Is this a bug or just handled differently? Thx T.
