When an alarm is triggered, the alarm notifier will be displayed indicating the details, along with 2 options: Stop or Snooze.
Stop - Turns off the audio and closes the popup alarm message. It will not re-alarm.
Snooze - Allows you to re-alarm minutes or hours later.
If the Auto Snooze option is selected, this alarm would re-alarm in 10 minutes, and you will only have to touch the snooze button for any remaining snoozes. There is a 20 sec delay to allow time to disable the auto snooze if you need to change the snooze time.
