And I was not aware of the 'P' key. :-)

Would be nice if it also printed column and meta information, i.e. if 
it included these lines:

  Samples: 1M of event 'cycles:P', 4000 Hz, Event count (approx.): 758731362801 lost: 0/0 drop: 0/0
  Overhead  Shared Object            Symbol

or so?

BTW., the approximate 'event count' is a pretty uninformative value 
these days, right? Might as well not clutter the screen with it.

Thanks,
