What did Carol Burnett do at the end of each show as a signal to her late grandmother?

The ritual started the first time that Burnett appeared on TV in the 1950s. She told her beloved Nanny, who said "Well, you gotta say hello to me". So they decided on this silent gesture, which Burnett continued to do at the end of each episode long after her grandmother had died.
