 msg.slash.required   = THINGS HAVE CHANGED: By default, all commands now start with a forward-slash ('/') character.  Any text that DOES NOT start with a forward-slash will be passed to the ``eval'' command.  For example, to execute the ``step'' command, type ``/step''.  To evaluate ``1 + 1'', you just need to type ``1 + 1''.  If you prefer the previous behavior, type ``/pref sessionView.requireSlash false''.
