With Q2 2009 (2009.2.9.729) and even Q3 2009 Beta (2009.2.9.1016), the end-user was able to type the ampersand ("&")-prefixed letter in the Text Property of a RadMenuItem on the ContextMenu to select that item. Starting with the final release of Q3 2009 (2009.3.9.1103), those letters are non-repsonsive.
