I had accidently scrapped all my Preferences while desperately trying to abort some bug ridden development code using (I hoped) <alt><.>. It has now happended a couple more times since. Is there an <alt> sequence that does this during a run? (Or did I press another key?) Wolfam support gave diagnosis and solution. To reset sensible default Preferences, launch Mathematica while holding <cntr><shift> (I think!). Thanks
