Brian wants to know if there's an easy way to search for things on his Mac. Leo says that CMD + spacebar will bring up spotlight search. He can just start typing and he'll find what he needs right away.
Bob wants to know how to bulk move notes from one address to another in iCloud. Leo says that he probably can't do that. He'd have to copy and paste one after another.
Brooke wants to know how she can restore a note that she accidentally deleted from her iPhone. She tried to restore it from her backup, but that deleted everything. Leo says the first thing is to turn off the phone so it doesn't backup. Hopefully it was backed up to iCloud, as it does normally. Chances are, however, that it's probably too late if she's restored from an old backup already. But if backup to iCloud was enabled, that's really her only hope.
